Overdrive help. popping out of gear and grinding.

I think it looks good 56. Some clean up as you said and reassembly with all the parts should do it. Some wear on the collar but no chipping.

The "stick out" everyone refers to, sets the total end play for the overdrive gearset. There needs to be some and not too much. Too much and it will pop out of gear. Too little and when it gets hot it will lock up. It doesn't need much, I don't know the spec, but I would guess it is somewhere around .010". You might be able to pull the PTO cover after install, and check the end play there.

Thank you sir! I lucked out with good lighting. Not really sure how/why but they did turn out good

I'll try to call Herm someday and get the correct specs and a synchro. Then see how it does.

Okay, back to work on the overdrive. I had put the stock gear back in it before, so I was able to drive it. Then got busy and never worked on the overdrive since. But now that the body is getting closer to being done and I'll have Flossy on the road this summer, I really need to figure this od out. So I put the planetary gears in and there seems to be alot of forward-backard movement. I don't know if this is normal?

With it pushed in the spacing is 0.511
Pulled out is. 0.558.

Seems really far from the .677 it's supposed to be. I did get a synchro from KW, so all I need is confirmation on the spacing. I'd like to hear your thoughts then I'll try to call Herm on Monday.

Like we discussed back a few posts 56', I think that number range is .667 to .680. Give Herm a call to verify. This number sets the end play of the unit. It needs about .010". A better way than stick out would be to actually measure the end play on the assembled unit. I am not sure if you can do that through the P.T.O. cover or not. If you can, that is the way to set it. Herm should have spacers to set the end play or "stick out".
