Sharing my motorcycle repairs, and motorcycle restorations with others. My interests are in 1960's and 1970's Japanese made motorcycles, mostly dirt bikes, dual purpose, and street scramblers of the era. You will see full restorations, engine work, machine work, welding and painting, all having to do with these older bikes. Follow along, I want you to hang out with me in my shop. I will show you how to repair components, not just replace parts. Based in Montana USA.
Convert a Lawn boy mower lower bushing to a needle bearing
In this video I bore the lower crankshaft bushing out to accept a needle bearing, I do this with the Jet milling machine, and a criterion boring head. Then I heat the casting to 250 degrees for 1 hour and install the bearing with the help of a rubber mallet.

I have to compliment you on your efforts to provide light and camera angles that closely show the machining processes (or any procedure) making it a LOT more interesting to watch. Especially since I find trying to properly illuminate a work area causes me lots of grief, even without trying to make videos! My kingdom for the Perfect Worklight! BTW I think it's so great that people choose to repair (and upgrade) lawnmowers and similar rather than simply throw them away!
Thank you Dale. Funnily enough i was looking to make a custom clutch cable for Triumph and during my headscratching, found Venhill selling the Bird Cage tool. I thought as you did, that's got to be easy to make. I can advise that their price is equivalent to approx 190 USD!!!... So thank you so much for a great video and saving many of us a lot of money. 😊
I put a Barnett clutch and springs in my 87 CR250 back in the 90s and man those are some STIFF springs!
Greatest lawnmower ever made! The old Brick top was such a cool design. I’m 66 and have managed to keep mine running and don’t plan on ever buying a brand new lawnmower. Great work Dale!
Thanks Dale. For those that might be interested this mower is 52 years old (owned by me) and had the original seals still in it top and bottom and it still ran and started great. Bottom of crank close to blade (side play) had far exceeded original specs and was super sloppy. piston and cylinder spec out like new still with no wear what so ever. don't even have to use my new. piston that I acquired about 20 years ago Ring end gap was close to 0.040 if you can believe that and it still had decent compression.. Steady died of 2 stroke lawn boy oil is all this machine has ever seen. Again thank you for helping me out here. Charlie
Great job Dale,never seen this model before.🏍
Can we see your lawn boy collection?
Have a f7 been in storage ( basement )for many years, all I had was 1st gear ? Doug ( repair shop guru) said had detent ball fall out of shifter - long rod ,,ball missing ? Called a leaner ( pagoda MC club )(70's old school). . . Local Kawasaki dealer ( been modernized)(they just want to sell new)( you have what?), can you tell where to go cause even Doug is now close to 70 (retired), thanks Tony ...
Awesome upgrade ,and awesome machine work, that lawnboy will be a screamer
Hi Dale, since you have a way to harden and temper steel, you might have experimented to see how hard transmission gears are. I have been thinking of making some but have not done hardening test on old gears. Do you have a hardness tester and what fact or lore do you have about how a gear is hardened and how hard is ideal?
Beef prime rib roasts,61ish in change 👍👍👍👍
Great bit of information and repair work there Dale! Keep it coming!
Great fix Dale. They used to make a two stroke mower here many years ago that had a 35cc J.A.P engine in. I have an old Suffolk Super Colt with a side valve four stroke. Made by the Suffolk Iron Foundry. Its from the 1970s, but the same design as the ones they made in the 1950s. Best wishes, Dean.
That is a good repair.
Thanks for the video, Dale. I subscribed a couple weeks ago when you were splitting the 2-cyl Yamaha crankshaft apart.
Thanks Wally, sure appreciate the subscription. Glad to have you on board.
Well it looks like you have some spare parts and some scrape metal , cool video Dale .
Yes it could be used but will require hours of machine work.
Yes we had new one Peace out 300 the cost of it
Thanks David
Excellent work.
Thank you John.
You forgot the best part 😀 They're Twostrokes braap 💨💨
Right on brother!
This will help for 1-2 years, but the real problem is the seals leaking after time. As an ex dealer in lawnboy we tried double lipped seals and even stacking 2 seals in the case. It all helps, but the seals will eventually fail. Keep up the good work !
Hey Dennis, I did this retrofit to mine personal mower over 10 years ago. Use it every season and have not put a seal in it since. Starts easy and runs great. Not to say it can't happen, just hasn't happened to me. I have tried the double stack seals and lipped seals too, and your right once the bushing is walered out the seal will never hold. But this prevents the crank from moving excessively. Just my experience.
great repair job dale should last a good whille keep up the good work next video please
Thanks buddy
It's been 30 years since I have heard a lawn boy run😂😂
Well, maybe it's time to find another one. Still a neat machine and there are no dead man devices, remember how simple things use to be?
Great video, I watched all clips in your LB playlist. You make it look so easy. My old C series “long snout” cases were not round OD bushings, looked they poured the brass in, then bored it out to fit. I have 3 from the 70’s that I use weekly & a couple of spare cases. No local machinists would tackle the conversion. Had the INA made SCE1412 bearings & seals already…
I think your right RC, I think the bronze was poured when they cast the cases. It's not real uniform. I am not surprised about the machine shop; I have a lot of folks tell me they don't bore motorcycle cylinders either if they are over 10 years old. I guess it's a liability thing. Sometimes I worry about it too, when I get a cylinder sent to me and it is insured for 1000.00 bucks. Makes me think twice before I bore it. Everyone messes up from time to time. I have done several of these lower end conversions and they work great. The one I did on my own mower has been running for over 10 years now, and I have not had to put another seal in it.
Thanks Dale! Cheers, Peter.
Peter....your back, great to see ya.
What's a lawn mower? las Vegas we have rock yards front and back! LOL
Frank you can sit this one out man.
@@montana2strokeracer hey, still interesting i had a lawn boy in California loved that thing made mowing fun,and smelled good while mowing.
I've had many Lawn-Boy lawn mowers all of them for free that someone sit on the side of the road they were always started right up and run until they were gone now I have an industrial one that pulls itself and then I have a bigger one that the parks used to use it has a lot of 200 cc displacement that I can see😅 I love these engines
They are still out there, I pickup up one a couple years back, put gas in it and started 3rd pull. Is the 200cc model the one that Suzuki built for Lawn boy?
As I said before , I dont think i have ever seen a LawnBoy . I will have to start looking . Thanks Dale .
They are so smooth
Look for a green lawnmower...
Just like Ron said, smooth, and green. Did I mention I premix my fuel with bean oil.......smells like Motocross! LOL
@@montana2strokeracer it is blendzall for me, nectar of the gods
On deck!
Awesome
Enjoyed seeing how these assemblies come apart. So when Barry Sheen was racing, was this the bearing he complained about in practice? The same one the mechanics refused to replace? Ended up failing in the race. Kenny Roberts won again that day. I imagine the race bikes were a similar design.
Hey Chris, not sure about the story, it has been years since I read anything about either of them. I'm sure the race bikes were a derivative of the street model with a lot of black magic thrown in for good measure. Oh, those were the times.
Hey Dale! You’re right, ring compressors for two strokes are pretty darn useless. I tried the new style that comes with ratcheting pliers. WAY easier the old way. 👍🏼👍🏼👍🏼👍🏼👍🏼
I have to admit I have tried a lot of different ones, always go back to my fingers. Now you know, thanks for the review.
You bet!!! Thank you for all the experience you’re sharing! It’s really made this bike fun to work on. I’d restored lots of motorcycles back in the early 2000s but they all ran pretty good. Now after this bike and watching your videos I’m happy to say I’ve got this thing running very well!!! Thanks again!!!
Thanks for the educational video Sir, I really enjoyed it, the skills you showed us will probably come in handy for me.
Thank you for hanging out in the shop with me, glad these videos are helpful.
Late to the party. Still fairly early Saturday morning here. Another excellent video Dale. If that rod had let go now THERE would be some carnage. Cheers, Peter.
No problem, Peter, yes there could have been some real problems for sure.
Just late lol
No worries Dale, some refreshments still left.
Not too bad considering the water had been at it Dale. You will get another run out of it I'm sure. I'm busy remaking my crankshaft splitting tool as the crusty B175 crank refused to move and destroyed the tool! Best wishes, Dean.
Wow broke your tool on that B175! Want to see what you come up with. Sounds like yours was worse than mine.... how can that be, must be that British salt air.
@@montana2strokeracer it was sitting with a full crankcase of water since 1977, so perhaps it's forgiven! Milling the new tool is proving to be hard work.
Take a close up with your phone, then bow it up, you won't believe what you can see.
Yes I forget about my phone camera at times, I have been using it more for stills to include lately.
Another Great Video Dale. Enjoy seeing you using your shop-made tools. Seeing these early twins shows how advanced engineering in Japan was at the time. Remember watching the duels between the 250 Bultaco singles and 250 Japanese twines at Ascot and the smell of bean oil heavy in the air.
Thanks John, it's fun making the tools, and when they work.....its gravy! Yes, I think they were advanced for their time, bet they sold a ton of those YL1's, just because they were a twin. Nothing like the smell of bean oil, I mix it in my Lawn boy fuel so I can have the memories while I mow the grass. LOL
Thanks Dale , any information on where to find vintage parts is always Great.
Thanks, buddy, I get a lot of tips from my viewers too. Much appreciated.
That tool you made works great on splitting them. Hope you can find the other piston.
Yeah I will find another someday.
Here
Awesome information about the connecting rods! As you know I need some, super good news. Keep up the good work!
Thanks Ron, I will let you know what I think of the Namura rods when I get it.
Yes that had rust on it Peace out
Love your stuff thank you from Fairbanks Alaska I have a new friend he's the chief mechanic of a fun center here in Fairbanks Alaska
Hey Richard, sure appreciate the kind words my friend. Sorry about the audio on this one. Not sure what happened.
One of the few things I'm learning for the first time today! Thank you for the patience
Welcome to the channel Amir, hope you find some good info here.
hi, Dale frank in blazing hot las vegas.
Hey Frank, waking up to 63 degrees here in the big sky, supposed to be 80 today. Good day for a ride......you want to come along?
@@montana2strokeracer OH! yeah crank them up, i would like to ride your Yamaha 360 flat tracker first, than a old favorite the Pursang.
Sorry I am late to the party, but I 100% agree that the new fender and gaiters update the look of the front end. It gives the bike a kind of Honda S90 vibe. Great work as usual!
No worries, Pete, I agree it is more along the S90 lines. Just looks so much cleaner and sleek.
Brilliant. Very detailed. Love your workshop too, very jealous.
Thanks for the kind words, John. Hope to see you in the shop again.
New watcher here. Keep 'em coming.
Welcome to the channel, thanks for spending time with me in the shop.
53:29, Wow! Absolutely beautiful beautiful bikes, I used to not be much of a fan of the MX versions, however they really grew on me the last few months, absolutely stunning
Thank you, Scott, they are a lot of fun, but so are the little street machines. Thanks for spending time with me in the shop.
Just discover your projects Dale ,enjoy every bit of it.Great job.🚴
Welcome to the channel Alvyn. Sure, appreciate you spending time in the shop with me.
Nice work! Originally came to your channel for machining but us hobbiests seem to have a lot in common with cars and motorcycles. Love the content.
Thanks Phil, you are right my friend, it just seems that working on cars or motorcycles require some machine work, it just increases the fun that can be had in the shop. Sure, appreciate you spending time in the shop with me.
