    Dale: I wish your videos were available back when I was stripping the enduros down to be dirt bikes. Lucky to have a manual back then. You are doing a great job.

      Thanks John, yeah, the videos are much better than a book, if the information is correct, there is always room for error.

    That case split a lot easier than any I worked on. Good job Dale. I think I have one of those little plastic caps laying around. If I run across it I'll stick it in an envelope.

    Looks like you've torn many of these engines down, knowing exactly what you're looking at. I certainly understand why you want to allocate your time to your own projects. Just never enough time. Not only that, but decent bikes for rebuilding are becoming hard to find.

    12:57 With regards to the grease on the gearbox output shaft I think its a good thing. I've recently had to replace the output shaft on my 30 year old Honda MT50 moped because the splines had suffered from 'false brinelling' (worn out!). Mind you on my moped the output sprocket is not held tight on the shaft, it can always wobble about, it's a bad design in my opinion. I think and I have read that grease can help reduce this problem.

    • @montana2strokeracer
      @montana2strokeracer  Месяц назад +1

      Yes, I can see it, think they were running on the beach in Florida. Yes, those Hondas have the two bolts that fasten the retainer to the sprocket, never thought it was a good idea.

    Hi Dale, what is your process for deciding where you need a shim when there is no documentation? mating gear being planar, or gaps or ??

    • @montana2strokeracer
      @montana2strokeracer  Месяц назад

      Are you referring to transmission shafts or crankshaft?

    • @rowlandcrew
      @rowlandcrew Месяц назад

      @@montana2strokeracer mostly the transmission and clutch side gears, but since I notice you comment on the crank spacers, there must be some objectives, like: keep things centered, no rubbing, teeth lined up, oil gaps.... I suspect that over the years there must be some trends or rules that the factories have shared.

    • @montana2strokeracer
      @montana2strokeracer  Месяц назад

      These transmissions have 3 different variations that I am aware of. Some use shims on the countershaft, others don't. I just like to see if someone has been in there and stuck some in where they shouldn't be. On the crankshaft it is just so you don't overcrowd it in the case. In an upcoming video I will measure the interior of the cases to make sure the crankshaft will fit. Thats the main issue, because when you tighten the drive gear on the clutch side it will pull the crank fully to the right side against the bearing and shim. You just want to ensure you don't have it too wide so that when you tighten the case screws it locks it up. This can cause a lot of damage. But if you build the crank to the specified width, you will not have a problem, just like to check and show folks what clearance is left inside the cases.
