Something Failed, let’s find it! Transmission Analysis.

just for taught about these clips
if u had a cap system that went over the clip to keep it from opening up when it is hammered. like for example like the old ford starters. might work
or if u used a clip w/o the holes then cut a recess in the part that hits it then it would not be able to spread the clip when engaged.

Something like this would be the $hit. Takes all the load off the snap ring. It would take up more room so would have had to be in the original design.

I found this write up, while it’s for an old model H2 trans, the principles should be the same:

Just from handling the output shaft I know for sure there’s at least 2mm between the 3rd circlip and the gear when it’s all shoved over against the circlip for 4th. Way too much space.

Hell, it sounds like there is already room for the center snap ring, just need the groove cut now.

Going to pass on adding it and just do bigger circlips and shimming it right.

Well here’s an interesting development....

Part #35 in the trans fiche is a splined washer that’s supposed to ride between the splined bushes and the 3rd 4th circlips.

GUESS WHOS TRANSMISSION DOESNT HAVE ANY #35s in it!!

Wondering if they’re omitted intentionally when the billet forth goes on at Robinson now?

Good forensics Rob...i will check mine when I'm next inside...won't be for a couple of weeks

I'm pretty sure I can't help here, but I've been encountering missing parts during my camshaft project, and just sadly is consistent with all bikes on which I've worked where a dealer tech touched it beforehand. Almost as universal as the bear $hits in the woods and the Pope is Catholic, if a dealer tech presumes that a part will be out of sight when the bike is buttoned up, parts *will* be left out.

They made some changes early on. Early gearboxes had a bushing and splined washers, later had splined bushings.

Thanks explains it, I must have the original manual lol
