Just found your channel, and man, underrated is an understatement. I've been in custom chassis fabrication now for about 20 years. Just as shown in your videos, this kind of work requires a strong foundation in all things mechanical with a sharp mind for problem solving. Really great content my friend. Hope to see your channel gain some traction with the UA-cam algorithm.
I put a Yamaha 570cc 2 stroke engine from a 1990 Yamaha Exciter snowmobile in a 1994 Yamaha G4 golf cart with a lift kit & some nice knobby off road tires etc. about 10yrs ago. Crazy fast without a roll cage & no front brakes! YIKES! LOL :-) Lots of fun though. I was surprised the stock rear diff held up just fine. I really like that gearbox though. I just need to freshen up the engine on mine with a new piston & rings kit & fabricate a roll cage & some front brakes. Makes me want to go out in the garage & get back at it, thanks for sharing! Nice build so far, my 1st video of yours, gonna check out the others.
Thank you for making this video. Not many people cover the gear box as well as you did. This to me is the make it or break it aspect of a motorcycle powered buggy or car. If you can't go in reverse the thing will get super annoying to drive.
Thank you for watching! The gearbox is expensive, but the buggy would be as enjoyable without it. I'd not attempt some trails because I'd be afraid of getting stuck with no way to back up...
Wow!! I got a comment from Ike!!! Huge fan of you guys!!! Thank you for watching one of my videos!! Next time you come to Oregon, gambler 100 mini bike race, I'm gonna try and find you to say Hi, and get a pic with you guys.....
Set up an adjustment like a car uses to adjust the belts on alternators. Screw adjusts through a pivot pin then a nut tightens it up to keep the screw from backing out. Would be easy to do on your set up. Would also help to brace it
Smiles all round, and like the gearbox...Just sad RPM doesn't have a better website or updated as the fab is wicked and sure they get lots of work but its 2019 you have to keep up with the online market
I am in the design stages of some dual-purpose machines and the forward-reverse aspect of the build had me slightly perplexed so this was super informative. I think that gearbox would be overkill for the small buggies I am going to build my grandsons, as they will be using pit bike engines, but for the big buggies that my sons and I plan to build this will be perfect providing it isn't 2/3rds the cost of my budget Lol! I have seen some other brand gearboxes going for nearly 3k. I can transplant a complete FWD drivetrain into it for that kind of money. Thanks for sharing and I wish I had your shop and tools LOL!
Letting you know I just called to get one for a 1300 Hayabusa. I did tell them I saw the trans on Moto-Mule. Hope it helps I hope I get a discount lol. He’s doing some planning to handle the power I’m wanting to push. It’s down to the tire size now.
loved the episode! I've been looking for info on reverse gearboxes. Your fabrication work is on a level of its own, super impressive. I like the new music loops too, much better.
Great unit mate it'll do the job perfectly I made my box outa an quad bottom end works awsum the chain is noisy so made a shroud to keep sound down ,lookin 4ward to you driving the monster mate cheers
Nice vid👍Is there a limit as to how far you can cant/tilt the gearbox?As you know,the more you tilt it,the oil level at the sightglass will change.....
What a phenomenal job geez you always impress us with your abilities and quality workmanship this channel is at the top of my watchlist,Can't get enough, good job ML
Your very informative and helpful I would love to have the tools and time for building things like you have built I usually have to start with something that someone else has built and fix it to what I want with all the wrong tools lol I really do enjoy your videos keep them coming
Well done ! i think this is the best set up i've seen with this type of RPM gear box, this was my first choice but I wanted to have 4x4. so i went for the maverick x3 gear box and adapted a sprocket instead of the clutch, so now I have reverse, HI - LO and 4x4. there are a ton of spare parts online for it and i run can am maverick axles.
Sounds like an awesome setup!!! I just picked up a RZR transmission from a parted out XP900. Very similar to your X3 setup. Saving it for a future project.... Thanks for watching!!!
@@motomule What kind of cost are the RPM boxes? i've been looking for one for a while but most are too expensive for their rated HP. Might be interesting to run a shaft drive from the bike motor to the gearbox then it can be used as a drop box to run in 4wd. Also been thinking of doing the same thing using a manual transmission from a FWD car, just rotated 90 degrees. so CV outputs run front to back.
That's a fantastic gear box and you have set it up awesome 👍 I seen your rpm link and the rear caliper an disc brake set up is a good idea but looks a bit small if it has weight an high up running through it but I'd imagine they'd have different grades for the buyers to choose from. You buggy is coming along real nice and built tough. Take care Mark.
Thank you!! I have brakes on each wheel, so I didn't consider the one mounted to the gearbox. It would add a little weight up high, but it would also remove unsprung weight which could be a bigger gain??? Thank you for watching!!
Hi , I’m so glad I saw your video. Very good explanation of how this gear box works and how to install it . Thanks a lot. Will this work on an old Vw Baja bug or Vw dune buggy with a Suzuki Hayabusa engine?
@@evanlewis2095 Nice!! I have a friend that has a UA-cam channel called Dirt Garage. If you haven't seen his channel yet, go check it out. He does everything in his yard too. Pretty cool. I've been collecting tools for over 30 years, everyone I have a few extra bucks I tuck it away for tools.. It's my "drug" addiction... 😆
You''re re inventing the wheel. These gear boxes have been layng. Around over 50 years. All u need is the gearbox from an Alpine twin track work sled by Skidoo. You're all too young to know. Haha
Dandahermit Seals I disagree, a skidoo box won’t handle all the load that goes through it, so much more force plus extra weight that goes through the boxes when you use it for offroad application then being on snow.
I'll tell you right now MR. Your days of chains stretching to death are over.. mine needed one adjustment .. were running nearly identical packages. blackbird 19/22 rpm 5.4:1 mine 1800 lbs though
Oh if I only had the cad setup, I can only imagine how much that bracket would cost for a machine shop to make 🥴. Anyway brilliant design Mike, I can almost picture how to mount the gear box, I just first have to figure out how I’m mounting the motor 🤔. I don’t want my motor in the back seat lol!
Great explanation on the RPM Gearbox. I've used them on 3 different builds in the past and your tensioner/ this b$*tch ain't going nowhere mount looks great. On one of the builds I added a small flex plate off a 22hp Honda v twin to the input shaft and used a starter motor off of John deere tractor, It worked great. Keep up the awesome work man!!!
Great work! Why not mount the breather filter upside down with a loop of hose extending a few inches higher than the actual filter? As it sits if the filter gets dirty (imagine that) and debris enters the hose it will be directed directly into the gearbox by gravity. With a loop higher than the filter any debris must defy gravity to enter the hose and fall into the gearbox. I'm assuming the "breathing" of the gearbox is very gradual as it heats or cools and there is no significant air velocity to factor in. And of course, when things break (they often do) having that little loop higher than the (now tossed down the trail) filter eliminates purchasing another $3,500 gearbox. Oh, and don't forget water. It goes downhill, generally. Cheers!!
Could you please make a video of how you make the switching mechanism between the Forward Reverse 0n your gearbox to the pedal and does it have a Neutral and Park? Thank you.
Awesome creation! I came, I learned, and now have a reverse solution. Speaking of filling with oil, that dry hardened nut shrieking in the lathe getting drilled out made me and my drill dr cringe. Stay sharp a lot longer with a touch of oil to keep the heat down.
Nice mounting bracket. What about oil in the gearbox? Is it OK to have the gearbox tipped at that angle assuming that their logo is the zero plane/angle? All the oil would collect into the output portion of the drive with no oil in the input gears.
Should have the pivot point axis as close to centered on the output shaft as possible in order to keep forces down. Landings and rough terrain will have a negative affect and I assume rear suspension will come into play with its physics as well.
Did the gearbox come with the oil level check window, or did you install it? If it came installed by the factory, does the factory have a prescribed orientation for the gearbox for proper check window orientation and proper oil function? If you intalled the check window, how did you determine where to put it? When tilting the gearbox to adjust chain tension, won't that change the orientation of the check window? What orientation will the buggy need to be in, in order for the gearbox to be in the oroper orientation to check the oil level?
Really cool build, but it looks like there is a ton of slop in the gearbox. Do you get a lot of driveline lash? I'm considering buying one of these for a crosskart I am building.
Love the fab work! Would it be overkill to add a spacer between those tensioner heim joints and use one long bolt to make them double shear at each end? Just thinking out loud while watching.
Thank you! I could do that up front on the motor mount side because those holes are in alignment. I screwed up on the rear ones, they don't quite line up with each other.... Thank you for watching and offering constructive criticism!!!!
Awesome I've also been thinking about getting 3 rear differentials (preferably) so I can CV shafts as drive shafts to a front and rear differential with cvs going from those to the wheels. Also thinking maybe could get a axle and run it sideways with cut down housings to differentials w/Cvs to wheels but that's alot of weight and I'm not sure how to work out the hearing I'd need in the center diff that goes the output shaft of the motor where a sprocket would normally by
Also I ideally would like to use a 250 cc engine I have laying around but I'm just not sure its feasible with all that rotating mass of 6 CV shafts and 3 differentials but also I think itd only be feasible this way cause I can adjust the gearing to whatever i need by changing out the center diff or the gear sets inside if i cant find a diff the correct ratio. The 250 also has a 4 speed transition on it. It is from a cheap quad
I went to the link and didnt show a price so that tells me to expensive to list a price , i bought a complete buggy with a reverse gear box for 700 bucks everything works but the chineezium motor smoked like a hooker on a friday night so dropping a gs 750 in it , hope the gearbox can handle it ....
I Love your videos, love watching you do things, you've got all the rite toold to Do just about anything you need.. keep up the good work, looking forward to seeing it roll. Thanks
The arrangement at 17:40 is fine to trim the drive chain but it is not an anti-twist structure as the extension bolts and the sheet metal work will flex vertically if the gearbox twists. Some higher thinking is required to make an anti-twist structure to aid that gearbox but most probably the gearbox alone can take what punishment it is offered.
Agree, and needs a diagonal (or 2) to resist twist. (think airplane fuselage, or wing, construction.).. so use turnbuckle to adjust chain tension only. (only needs a lightweight unit). Also use a riveted link chain as split link is a point of failure in anything over about 50hp. (ask me how I know).hehe
Top of your breather hose should be facing downward so when you wash it or run it in the water or rain the water will soak the filter and it won't just run down into your gearbox use a piece of 5/16 tubing put a 90°bend face the the filter down love your videos good clean work well thought out
Very Awesome Video ! Thanks for all the information and well narrated explanations my first time on your channel but i will watch more especially on that Buggy build that sounds pretty cool to me
That is an amazing unit, but you failed to mention that it costs as much as a decent car....out of range for most people.....beautiful job on the cradle!!
Thanks. True, it's expensive. But adding up everything I have into this project, I'll be into it less than half of a new RZR.... Plus, I get to say I built it, and it's paid for!!! Thanks for watching.
Excellent fab work . I wonder if that set up would be enough to power my baja bug ? I have 25K in. I Hate the VW motor . over heating . 2332cc . yes 930 cv ?
I have seen people adapting outboard engine V-6 powerheads to VW transaxles. Then using an electric water pump and small aftermarket radiators with electric fans.
hey great work very helpful video i have been building for a while now and that is one of the best setups i have seen yet i am sure it will get some attention very nice
what's it like driving without a diff? I know go karts deal with it by the nearside rear wheel slightly lifting off the ground in corners. But with on a buggy with suspension, that nearside wheel is going to be pretty glued to the ground.
The diff has fuck all got to do with ns wheel lifting that's shocks an chassis ,lock diff just drives both wheels all the time same as each other, open diff naer side wheel wen in a turn rotates less than outside wheel = SLIP DIFF, ,on a lock diff it causes oversteer easier AS the inside wheel is spinning in correspondence with outer wheel travelling furter ,likely causing regular oversteer in tighter corners using a fully locked diff car , LIMIT SLIP diff is best of both worlds ,easier to live with ie tyres an predictability so is more fun, trust me,
Your pivot should be around the centerline of the axle. Your adjusters don't allow you to shorten enough to change the chain. So how do you shift from forward to reverse?
Sweet! This was what I was waiting for. Detail on the gearbox! Side thought...should that chain be a riveted style instead of a quick link? Seems like once bikes get past about 650cc they start using fully riveted chain connections instead of the quick link?
The shaft is as hard as a standard motorcycle counter shaft. I believe the sprockets are a bit softer (they show more wear). I have over 150 hours on my RPM box without significant spline wear. I'm also running close to 200hp in a 1300 lb car.
@@plkracer It's your project, but if I saw wear after only 150 hours, I would be concerned. I know that XR650's have issues with gear and spline wear, which utilizes a similar sized gear. Good luck with the project. Looks nice.
I was a cranky bugger until you introduced the Heim joints to tension the box. You have my attention now! Continue please.

This would be perfect for my street bike engine in my vw bug
Nice Work!
So what stops you from twisting the box when you tighten the turn buckles to diffrent tensions dino how to explain it beller
I'll need to move both turnbuckles together, you are correct, if not careful you could twist the box with the turnbuckles. Thanks for watching.
Sounds crazy but could I use this set up to power my 1991 Toyota fwd celica?
Probably not, it has no differential, it would be crazy hard to steer....
Looks like a well thought out quality product.
It is very well built.

Would a belt instead of a chain keep the heat down a little better? Maybe that could be a back up plan
Not sure??? I'm hoping this setup proves itself... Thank you for watching!!!
Smashed the like button as always. Keep up the awesome work.
Thank you!!!!
Think this will handle the stress of being turned sideways to be sending the output shafts longitudinal instead of transverse.
If you were using it to feed differentials, that would lower the stress that this would see, because of the gear reduction past it. So, yes.
Awesome I've also been thinking about getting 3 rear differentials (preferably) so I can CV shafts as drive shafts to a front and rear differential with cvs going from those to the wheels.

I went to the link and didnt show a price so that tells me to expensive to list a price , i bought a complete buggy with a reverse gear box for 700 bucks everything works but the chineezium motor smoked like a hooker on a friday night so dropping a gs 750 in it , hope the gearbox can handle it ....
@@4486xxdawsonI inquired about one for my project and they quoted $2200
I Love your videos, love watching you do things, you've got all the rite toold to Do just about anything you need.. keep up the good work, looking forward to seeing it roll. Thanks
Thank you for watching!!!! So close to being able to drive it....
The arrangement at 17:40 is fine to trim the drive chain but it is not an anti-twist structure as the extension bolts and the sheet metal work will flex vertically if the gearbox twists. Some higher thinking is required to make an anti-twist structure to aid that gearbox but most probably the gearbox alone can take what punishment it is offered.
Agree, and needs a diagonal (or 2) to resist twist. (think airplane fuselage, or wing, construction.).. so use turnbuckle to adjust chain tension only. (only needs a lightweight unit). Also use a riveted link chain as split link is a point of failure in anything over about 50hp. (ask me how I know).hehe
Nice Job! looks solid! Do you have the cadd files you used?
Top of your breather hose should be facing downward so when you wash it or run it in the water or rain the water will soak the filter and it won't just run down into your gearbox use a piece of 5/16 tubing put a 90°bend face the the filter down love your videos good clean work well thought out
Yes, I need to fix that. Thanks for watching!!
Very Awesome Video ! Thanks for all the information and well narrated explanations my first time on your channel but i will watch more especially on that Buggy build that sounds pretty cool to me
Thanks!! I plan to get back to work on that buggy here soon. The weather is finally starting to improve!!!
That is an amazing unit, but you failed to mention that it costs as much as a decent car....out of range for most people.....beautiful job on the cradle!!
Thanks. True, it's expensive. But adding up everything I have into this project, I'll be into it less than half of a new RZR.... Plus, I get to say I built it, and it's paid for!!! Thanks for watching.
fabricationnation hasn't been to a car lot in 40 years.
Be nice to have a shop with all this euipme t.makes everything so much easier
That things awesome!! Can’t wait!
Me neither!!! Then we can get work on toddler beds!!!
Yes sir!!
On the other side you can add a small alternator on shaft from your gearbox for back up battery, just an idea..
Cool idea. Thanks for watching!!!
@@motomule I have pictures of my RPM with an alternator on the FB group, if you go that route.
@@plkracer I will check that out, thanks!!
What did younuse for the shift lever for F N R?
I'll show that in the next video for that project!
Could this gearbox be optimized for use with a Honda Valkyrie engine since the Valkyrie is a shaft driven bike?
Don't think so, it's designed for chain drive setups.
@@motomule Dang, that sucks but I appreciate the quick response. Thanks man, great content!
I have garage envy. You have some great tools. 😁✌
Thanks! I've been collecting tools for over 30 years... Thanks for watching.
Good teacher , i like the way you explain
Excellent fab work . I wonder if that set up would be enough to power my baja bug ? I have 25K in. I Hate the VW motor . over heating . 2332cc . yes 930 cv ?
Not sure?? Yes, 930 CV's.
Have you seen this bug??: ua-cam.com/video/_uxUB9h4A_k/v-deo.html
I have seen people adapting outboard engine V-6 powerheads to VW transaxles. Then using an electric water pump and small aftermarket radiators with electric fans.
It seems like this could work for a tracked vehicle too, with a hydraulic motor.
Maybe, but not a skid steer, it has no differential. Thanks for watching Kevin!!!
hey great work very helpful video i have been building for a while now and that is one of the best setups i have seen yet i am sure it will get some attention very nice
Thank you!! I can't wait try it out. Thanks for watching!!!
Buen día a gracias seńor por compartir su gran trabajo ,me suscribo estoy suscrito éxito siempre
what's it like driving without a diff?
I know go karts deal with it by the nearside rear wheel slightly lifting off the ground in corners.
But with on a buggy with suspension, that nearside wheel is going to be pretty glued to the ground.
dfpguitar I’d assume just lots of oversteer
The diff has fuck all got to do with ns wheel lifting that's shocks an chassis ,lock diff just drives both wheels all the time same as each other, open diff naer side wheel wen in a turn rotates less than outside wheel = SLIP DIFF, ,on a lock diff it causes oversteer easier AS the inside wheel is spinning in correspondence with outer wheel travelling furter ,likely causing regular oversteer in tighter corners using a fully locked diff car , LIMIT SLIP diff is best of both worlds ,easier to live with ie tyres an predictability so is more fun, trust me,
Your pivot should be around the centerline of the axle. Your adjusters don't allow you to shorten enough to change the chain. So how do you shift from forward to reverse?
Sorry this question is so late. On the reverse box. The shaf opposite of the sprocket. Could you run a pulley for ac?
@@korosuchimu1479 not sure? Probably, but it's designed for a brake.
Ok this is what I’m looking for to power my vw bug with my GSXR 1000 motor that’s awesome!
Sweet! This was what I was waiting for. Detail on the gearbox! Side thought...should that chain be a riveted style instead of a quick link? Seems like once bikes get past about 650cc they start using fully riveted chain connections instead of the quick link?
I'm using a quick link on this, but yes, most big street bike use riveted links, no master link.
I have a rpm box also and my chain is riveted, I went for that option cause my motor is a zx1400 and push a fair of power through it.
My question is how are you going to shift from forward to reverse with the shift shaft behind everything?
Would it make sense to add a splined spacer that bolts to the gear? It looks like that thin gear is going to wear that shaft pretty fast.
The shaft is as hard as a standard motorcycle counter shaft. I believe the sprockets are a bit softer (they show more wear). I have over 150 hours on my RPM box without significant spline wear. I'm also running close to 200hp in a 1300 lb car.
@@plkracer It's your project, but if I saw wear after only 150 hours, I would be concerned. I know that XR650's have issues with gear and spline wear, which utilizes a similar sized gear. Good luck with the project. Looks nice.
Hey, where did you get the RPM sprocket from? I'm trying to get a bigger tooth spocket of at least 23T.
Do they make these for a predator 420cc engine??
Nice project !
Thanks for watching!!
Very informative video 👍
Nice video!
Wow exactly what I'm looking for🤯. Nice awesome build 👍
Thanks!!! Thanks for watching!!
Nice video! Do you know the thread/fitting size for the breather? Thanks!
I think it is just 5/16 hose fitting. Thanks!!
