First, how do you know if you have offset cotters? Splitting the cases only? Then, what is the process for installing the offset cotters in a CA77 Dream? Remove the motor, disassemble the clutch and primary chain, and turn the motor upside down so the bottom half of the case can be removed while the guts stay in the motor?
How difficult a job is this?
My 1965 Dream 305 with its 1964 motor is a little funky (can almost feel a few teeth going cllltttt upon shifting from 1-2) going into 2nd at times and I'm wondering if the cotter issue is what's causing it. Never has popped out of gear, though. Also a little tricky to find neutral when warm, but that is rare.
Installing updated/offfset cotters...I take Advil for my offset cotters. No charge for that... Now:
Yes, the only way to know is to split the cases and you have the right idea. Not that it's hard, just takes time and not worth it especially if it's not broke! When these transmissions wear a little, they can have problems with dog engagement, especially second gear. The shift fork doesn't slide the gear over quite far enough and the offset cotters are the fix. If the dogs are rounded or not engaged far enough initially, it can pop out of gear. The gears are always meshed in these transmissions, the dogs are not and can make some noise when they engage. Try shifting a little firmer and you shouldn't really hear anything. Find neutral while rolling is a fact of life for some of the clutch configurations when hot and would have nothing to do with offset cotters. I attached a picture of the trany in second gear. The two middle gears on top are engaged by the "dogs." You can't see the offset cotters, but they position the stationary gear on the right, over to the left a little for more engagement. -48
Did I hear you say "keep on riding big fella?" I think that's what you said. Thanks. I will do just that. :-)
