Thanks for watching. This mower's self propel "kinda" worked but the fix was not easy.
I repaired an old school Snapper transmission using a parts diagram. It was time-consuming but it was my mower and I did find the repair process very satisfying; particularly considering the cost of a new transmission.
wow nice work, you really wanted to keeping it work and I respect that.
Thanks for the content today
no problem and thank you Mike Hittner for your time.
Genius idea what you did with the pin. Great video as always 👍
Thanks! I'm glad you liked the fix.
I have used cotter pins to replace roll pins as long as it doesn't interfere with mechanical rotation
that's a good choice
Great job sir. Great job indeed.
thank you Paul Betker
A zip tie can be used as plastic filler for building up parts and as long as a Snapper got a sniff of their 00 grease once in a wile there was NEVER a problem with the rear end. My 89 was flawless but the one I got that was DRY and FULL of leaves just took a new pinion gear and just went right on running. 00 grease is in between gun grease and oil, a gun grease that sags. I used it in all matters of things and can be gotten at Tractor Suppy called 'Cotton Picker Spindle Grease' but still has the 00 number, just not the Snapper prefix. Good stuff and Happy weekend!
yes I've used the zip ties like that before. I'll need to get a hold of some grease, however since oil came out of this one, that's what I put back in.
@@HomeGaragechannel Sounds like a plan! Happy weekend!
thank you!

Any Video gets a like even though I don't have time to watch some of them !
Keep Em Coming !
thank you very much Furrowx! It means a lot to me.
I would definitely attempt that repair and or replacement never a nylon or plastic gear set with oil bath like that all the ones I have taken apart were dry or a amount of white lithium grease and I have never seen sealant oozing from the covers and on the actual primary and planetary gears
you know what you're right. The times I've taken one of these apart, it's typically grease but that was Front wheel drive. Since this one is mostly plastics, that's why it's oil.
I don't think they originally came with oil because typically petroleum based oil will soften and degrade most plastics and even quicker when heated.Its not like that application is a rear differential like on a rear wheel drive truck or car
from the owners manual, the 2 lubricants were either gear oil or lithium based grease. Since this one is not the metal case which requires the grease, it must be the gear oil.
Good job and i agree about replacing the transmission.
thank you, It makes good sense
Well done as usual!
Thank you for watching!
Nice repair video, bro! I’ve never seen a lawnmower transmission torn apart. I am a small engine mechanic, but still fairly new to the trade and haven’t had to tear into a transmission yet.
thanks man. If I was working at a repair shop or if I owned it, I would not recommend this fix because of warranty issue not to mention time. Most consumers would never pay to have this repair done and with no guarantees either.
@ I hear ya. My dad opened up a transmission (may be a CVT as it is variable speed, no “set” speeds) on a 20 year old Husqvarna mower one time and fixed it successfully. He gave me the mower and I still have it. I’m looking to sell it. The unit is a 1999 model with some kind of plastic or fiberglass deck, still in solid condition. Has a 5.5 hp Briggs Quantum on it. So yeah,it’s 26 years old now, and still fires right up.
nice, but you don't want to hold on to it and use it? Sounds like a great mower.
@@HomeGaragechannel True story: I struggle with that very decision.. It’s 26 years old without a spec of rust on the deck. It was given to me by my uncle. Before that, It was given to him by a neighbor. I gave it to my dad and he went through it, fixed the transmission and then years later, gave it back to me because he & my mom have a very large yard and don’t need it. Needless to say, it’s “been around the block”. 😂 It was hardly used during the time my dad and I have had it. It does smoke a bit on startup, but then quits once it warms up. I keep an eye on the oil level. I thought about putting a 20w-50 oil in it and see if that eliminates the smoke on start up. Otherwise it starts easy and runs like a clock.
I also have a Toro 22 inch mower that’s practically brand new. It was given to me. I think it was used once. The previous owner stated that the self propel didn’t work. I turned it over and the only problem is the pulley on the shaft was not the correct one for the motor shaft diameter. I don’t know how a mistake like that was made at the factory. It had a battery-electric motor. If you know anything about Toro’s, their battery-electric mowers are built just like their gasoline counterparts, except they have an electric motor. I took the motor off, replaced it with a sweet “Briggs & Stratton Professional-Series” 175cc OHV engine that came off a Troy-Bilt mower that I had new since 2010 or so. The self propel pulley from the Toro fit perfectly as this engine shaft has a larger diameter. The Briggs motor is still a beast. I knew when I bought it, the engine would outlast the rest of the Troy-Bilt, and I was right. I’d put that engine up against a Honda GCV any day. It’s built better and more heavy duty. I’ve change the oil, replace the plug, replaced the flywheel key when I hit a root (didn’t bend the shaft) and adjusted the valves once. So, in my view, I have a brand new Toro Personal Pace mower for free. The engine on it is as good as new, even after all these years. There’s no carbon build up in the muffler. So, what would you do? Keep the old Husqvarna and the new Toro, or the new Toro and sell/give the Husqvarna?
I have a 1 acre yard so I usually mow with a rider. However, I’ve used a walk behind before I bought a used rider. I now use the walk behind for the edge work and a hill. I value your thoughts as I watch many of your videos.
I have yet to get a hold of a Toro with a battery, but maybe this year. Also the 175cc engine is fantastic, at least in my opinion, too bad so many people neglected them. Wow, it's been a long time since I've mowed an acre with a walk behind. It took hours to do. Can't do that anymore at my age, so I'll just keep it as a memory from years ago. And thanks I appreciate your time watching.
If it worth saving and you can fixed it why not great job 👍
thank you very much Gary Higgins
Good fix that pin won’t move till that mower is kaput👍
my thoughts exactly
I’ve got a mid 2000s craftsman 22” front wheel drive mower that tends to not go straight with self propel activated. Would that be an issue with the wheels being worn out on the axles, or maybe the gears might be stripped. Besides that it runs fantastic, starts in 1-2 pulls has the tried and true reliable Briggs & Stratton 6.75. Got it for free from a neighbor and after about ten bucks and some carb cleaning I got it running in a couple pulls. Heck of a lot more durable than some of the cheap junk we get these days. Your channel is one of the several channels that have helped me learn to diagnose and fix many running issues with mowers and two stroke machines. If you possibly have an answer for the issue with it going straight, or maybe you already have a video on it, that would be awesome. Great video as always, and thanks again.
thank you so much for the compliment. As for the mower, I would have someone start it, left of the front and activate the drive. Then I would "carefully" grab the front wheel and see how much force it takes to make it stop. If both take the same amount to get them slow down, the issue is not the drive but could possibly be a wheel alignment issue.
TY for Sharing
You are welcome, I appreciate you watching.
Yeah, I think that level of repair is quite impressive and can only be done or attempted by a few people, but I probably would have just turned it into a push mower
I know what you mean. If the gear had been in bad shape, I would have made it a push mower as well.
I would like to investigate it I've never done one so I would love to learn thank you for the video
You got it. Doesn't hurt to give it a shot!
I think the engine Oil had a strange color - much like a molten snickers. On a car Engine this is a sign of having coolant in the oil (the more the color goes towards caramel the more water...)
I know right, not sure why it looked like that.
Hey that’s a great fix! I definitely would’ve given the same repair a shot. I always keep some of those General Transmission gear boxes around for 22” Toro and AYP mowers, but honestly I’ve never come across a bad one yet. I’m sure it’ll happen sooner or later, though!
I know what you mean. I try to keep spares but I typically end up not needing them .
Any fix that works is a good fix. I would have done the same repair, or pull it apart, take careful measurements, then make replacement parts from alloy for longevity.
I like the way you put it.
$70 for the transmission, $3 new air filter, $3 oil change, $24 labor(low side) = $100. To sell for $150 in my area. Not enough "meat" on the bone for me.
oh I know what you mean. The margin is so thin you can see thru it.
it was worth trying the repair before buying a new trans. I like those lawnboys.
totally agree and yes I think lawn boys are a great brand too .
This would be a good opportunity to learn 3d print gaskets.
I didn't know they made filament like that, I'll have to do some research, thank you!
@@HomeGaragechannel TPU is a flexible filament, but have heard it can be difficult to use. I believe it's resistant to some oils, as well. I haven't used it yet, but I only 3D print as a hobby using other people's graphical design skills
thank you for sharing that.
I would attempt to repair. A self-propelled mower with a broken drive system is harder to push than a simple non self-propelled version. This, IMO, is the weak link on Toro mowers, and that transmission looks a LOT like the one in my Toro. Thanks for the tips on a possible repair.
no problem and thanks for the time.
Hey bro what's up? At least you tried and although it wasn't an ideal repair but whatever gets it working again is all that matters.
so very true!
I miss the 2 cycle version of this lawn mower 😢
2 stroke engines were designed by the devil
me too.
@HomeGaragechannel they're are hard to find in running condition
yes I agree
@HomeGaragechannel ✌️👌😎
Always attempt the repair fjrst. Worse comes to worse, just buy another transmission. Its another learning experience!
very well said!
Thats a great idea, melting the pin into place, it's cheaper to do that, then buy a new transmission, especially if the person I'm doing the work for is on a budget, and can't afford a new transmission, and needs the mower to last for a season or two, maybe more
very well said! I would hope they appreciated the mod too.
I recently picked up a Troy Bilt Tb110 with a Briggs 140cc engine for $10. The deck was in rough shape and the seller said it was locked up, so I bought it for parts. It turned out to be a bad recoil and I had a better deck for it, so I ended up swapping the deck and getting it running. It's running great, but it is definitely running fast. I have never adjusted engine speed on one of these. Which direction do I bend the tab to slow the engine? I don't want to risk bending it the wrong way and speeding the engine up any more.
sure thing, push the tab, towards the back of the engine. This will reduce the tension on the spring.
It should be a crime to use sealant instead of a gasket to prevent repairs.
I know, I wish there had been a gasket alternative for this part so I didn't have to use sealant too.
I have a 2017 Toro Personal Pace that threw the drive belt. I put a new belt on it, but I cannot figure out how it threw the original one. Nothing was damaged, and I certainly couldn't put it back on without disassembling everything. I tried. It's so weird. I am giving this machine to my little brother, so I probably going to have to wait til Spring and put it through the paces (pun intended) to make sure that it doesn't do it with the new belt.
I know what you mean, with all the guards on there, it shouldn't have thrown it. Hope you figure it out and it won't throw it again
If it is my mower and I am keeping it, I would do the same thing you did. It would be a tough decision if it was a customer's mower or one that I am selling. I would leave that decision up to the customer, but I would never sell one with a rig job like this, since I wouldn't want to risk selling them a machine that could quickly become a problem.
you make a good point. I had the mower for awhile, not sure how long but I did eventually sell it.
That's the thing about this hobby, lol. When you bring one back from the dead, it is hard not to get attached. If you get too attached though, you end up with 17 of them, like me. I'll have a great Spring though. I have some pretty good machines, and as of yet, I have never paid more than $10 for an individual machine. That's my limit, lol. I'm a cheapskate.
I know what you mean, I've got a huge overstock ready for spring. Also $10 is fair, however I will pay more for a "good brand" that sells at a higher price.
Toro never had parts for those but at the time a replacement was only 30 dollars now they are 70 !
quite the jump in price!
something i thought about; you could have technically used a 3d printer to print new gears with stronger plastic, but im assuming you don't have one so thats probably out of the question. something else i thought about was to melt the gear on the other side so maybe the same thing didnt happen
you are correct, In fact I think I asked that before on the original version of this repair... "should I have melted the plastic on the other gear".. Most people said I should have too. But this mower is long gone so hopefully it's still holding up .
Niceee
Appreciate the view!
Ninja.
We used to remove the drive engagement as they are more trouble than their worth. If you can't push/pull the lawnmower, you probably shouldn't be cutting the grass yourself.
sound advice
Nice fix. Too much time investment for me. I would have removed the transmission and made it a roller. Those 20" lawnboys aren't overly heavy. I did disassemble, repair, and refill the transmission in my lawn vacuum, but that was only bc it was going to be my personal machine. I also did the drive belt this fall, and will NOT do that again!
wow.. I've never had to change the drive belt on that vacuum before, thanks for letting me know what I could be getting myself into.
@@HomeGaragechannel It took over 2 hours total, and it requires a special tool to remove the flywheel/chipper underneath. You basically have to separate EVERYTHING to get to the pulley on the crankshaft to install the belt and then re-assemble it all. Luckily, it only gets a couple hours use every year, so it should last quite a while. If a customer came to me with the problem, it would likely be too costly a repair with the time investment and parts. I still need to get it put back away in my shed, but got behind the game with the snow we had and now it's a soggy wet mess everywhere.
I know what you mean. I left a couple of items out too.
