I’m just about to recouple my Cub after replacing all of the clutch components with new parts from TM. I’ve read most of the numerous threads on this topic. Bearing was soaked in frequently warmed oil for 8 days and greased with “cheap” grease. New yoke from TM pivots freely but has almost no side to side play. TOB centered. Fingers adjusted as recommended.
I feel pretty good about it right now. My only question has to do with how much exertion it should take to rotate the TOB in the yoke. At this point it stays in place when I move the yoke. But, I can rotate it easily with one finger. I’m not sure if once the tractor is running if it is best initially to have it a little tight due to vibration once the tractor is running and moving.
I know this is a hard question to answer without feeling the fit.
My question is:
Is it better to have it a little stiff when first installed expecting it to loosen fairly quickly as it gets used?
It stays in place now. It’s by no means loose, but rotates pretty easily and I’m wondered if after a fairly short period of use if it’s prone to loosen some so having it a little tight initially is a prudent approach.
Thanks

A snug fit is good, It sounds like it should be fine as it is now.

Thanks Gary. I didn’t really want to take it out but figured now is the time to ask.

Re: How tight should TBO rotate in Yoke
I did think of one other question. My TOB came pre-greased from TM. After soaking it in oil and installing it, I figured I should squirt a little of my black general purpose Walmart grease in just to make sure grease comes out the top hole. White colored grease came out which is what TM used. I put 3 pumps of my grease.
I have read to not mix grease. Maybe that’s just what the manufacturer puts on the cartridge so you’ll always look to buy the same brand of grease. Since I now have introduced my new grease should I grease it until I see my black grease emerge from the hole? Or, in this application is that unnecessary.
Thanks

Re: How tight should TBO rotate in Yoke
Most of the concern about mixing types of grease has to do with mixing additives used in various brands. The cheaper the grease, the less the concern about mixing. It shouldn't matter in this application.

Re: How tight should TBO rotate in Yoke
you want cheap grease in the bearing, it needs to melt so the graphite can absorb it, good grease does not melt so the bearing fails from the graphite being dry, I soak the new bearings for a least a week in oil before using them

Re: How tight should TBO rotate in Yoke
Hi,
Be sure the throwout bearing is held snugly by the holder, squeezed in from the sides.
If it turns too easily in the holder, the top of the bearing can flop forward, and rub on the pressure plate fingers.
Adjust the bend of the holder, if needed, so it holds the bearing snugly.
I would check the holes in the holder.
The holes in the holder can wear, then it becomes too loose, and can move up and down, or side to side.
The holder shouldn't move up and down or side to side.
The pin at the top of the holder can wear too.
TM Tractor has a new holder, if the Cub has the newer style external adjustment, and pin, if the parts are worn.
The holder is different for the Cubs with the internal clutch pedal free play adjustment.
The top of the holder should be almost as wide as the space at the top of the clutch housing, where the pin is, so the holder can't move side to side.
The bearing should be centered on the 3 pressure plate fingers.
