clutch finger failure

I had chatter in the clutch so I opened up the hand hole to adjust and found that one of the release levers had failed. Interestingly, it still shifts and appears to "clutch" fine.

I have a parts facing here that needs new adjusting screws. Would you guys recommend getting a new plate, or swapping the adjusting screws and using the plate that I have?

The TOB is fairly new, but I need to check it also.

I would check into the possibility of having the plate rebuilt. At the bash someone mentioned of a shop in Nashville that could rebuild a cub pressure plate for around $50.

What is interesting to me is that I've adjusted the fingers, including the bent one in the top picture and the clutch functions perfectly. Probably better than many out there.

Is there a way to replace the one bent finger through the hand hole?

I do have the extra plate (shown in the second and third pictures) that I have on the shelf. It is a good plate, just needs the adjusting screws.

Thanks,

Todd

To my way of thinking, what've you got to lose by trying?

Just make sure you've scheduled enough downtime for the tractor to accommodate a split if your attempt to replace the arm through the hole doesn't pan out...

Looks to me like all the fingers are shot. The culprit is the replacement after market throw out bearing. The new graphite bearings are not impregnated with grease like the originals. Also to build that much heat the burn the fingers like that requires a lot of riding the clutch or holding the peddle down for long periods of time. I would not use a after market graphie bearing. Steiner has come out with a new automotive type throw out bearing that seems to work very well. This new bearing is actually a thrust bearing. Be ware of cheap aftermarke pressureplates also. they will cause problems. Rockferd still make new clutch parts for the cub. Reason being the cub size clutch is used in many old garden tractors and power units so there is a demand for the clutch and components.
