Where does this retaining ring go?

Postby MikeEyre74 » Wed Jul 24, 2019 4:31 pm

I took apart my whole transmission and creeper gear assembly because there was some broken stuff. I got both assemblies back together and... ended up with an extra part.

Rats.

Any idea where this spring steel snap ring goes? I’m *pretty sure* it’s a creeper gear piece... but not totally positive.

Yup, creeper. Called "ring internal retaining". Goes in the outer end of the creeper case to hold everything together.

Parts manual shows the parts and where they go.

Does that mean I gotta press it all part again? <groan>

I don't know. Take a look at the parts manual and then the outer/front portion of the creeper case. From the parts manual it appears to snap in, holding the other parts in place.

This isn’t that, then. That ring #20, is in place and much larger.

There it is in the housing, with the mystery ring held in my hand.

Hmm. How about this:

https://flic.kr/p/2gGemcf

#3 is listed as “Bearing, countershaft” and is hidden just underneath the bearing retainer cap. I pulled the cap off and there is nothing under there, but the bearing, counter shaft number three is pointing at the bearing and what looks like a split ring like that thing that I don’t know where it goes? There are witness marks on that split ring that sort of match up to some machine marks on the inside of the bearing retainer cap? Otherwise, there is nothing in there. Might that be it?

Check part number 11, cap retainer bearing, and see if the snap ring comes close to fitting in the end cap.

From the parts manual the snap ring has to fit some where between the two bearing retainers.

It doesn’t come close, it fits *perfect* inside that cap #11. And there are wear marks that indicate that that’s where it was now that I look... but it just doesn’t make sense to me? Why a split ring there? Why not just a washer if that’s what they were looking for? I’d love for someone to chime in and say “yeah, it’s weird, but that’s where it goes.. I just had one apart”.

As it turns out, it actually goes *right there*, as I found out the hard way.

But it makes a world of difference.

You know that your flicker pics are extremely helpful to others- even if they aren't signed in or don't reply. I'm glad that the ring was replaced to its proper location. If you hadn't took the time to do that- well it didn't happen.

You know how that mystery was solved? The Standard Cub forum! There was a fellow there in exactly the same predicament but he wasn't working on a numbered series. I just happened to see the post and what he'd learned. Amazing, the amount of information here, separated by a couple of keystrokes or mouse clicks... that might have gone unsolved and led to my transmissions destruction!

PTL you didn't let it happen. I hadn't been following that particular bearing or ring but later when I LOOKED at the exploded diagram, I SAW trouble of a different sort. Generally any original bearing which has an outer groove, is looking for a retainer ring. I hazard to say but the precise shims for the pinion/ ring lash could be upset if the bearing itself was shifting. Not able to say that with authority but the pinion / ring are spiral helix gears. In one direction they may be okay but in another, not. They tend to either pull or push. Anyway; I'm glad for you and I suspect your new gears work fine.
