Bobcat 610 Driven Sheave/Jackshaft Bearing replacement.

[Grundy1700]

I think I need to replace the bearing for the jackshaft on my driven sheave. Oil leaks down the left side of the frame, and I can see, (and hear), the driven sheave bouncing around. How hard is it to pull the bearing off of the jackshaft? If I bought a gear puller, I believe I could easily get the sprocket off. But then I am worried about getting the bearing off with it's housing. Is there anything to grab onto? Can it just be pulled off, and pushed back on, with the jackshaft still in the machine?

Grundy….jackshaft bearing replacement is a pretty serious job. Shouldn't be undertaken without a manual. There are also several threads on this subject on this forum that will help. I guess you COULD replace the bearing without pulling the shaft but it is not something I would do as there are too many other things to check during this job. You will have several alignments to insure are correct in both sides, chains and clutch linings to check…..this is also a perfect time to assess the condition of the driven sheave bushings and rebuild the roto-swivel assembly if necessary. I rarely go that deep and NOT find other things that need attention.

Thank you for responding 6brnorma. I have not been able to track down anyone to do this kind of work on an old machine in my area. I will have to try harder to find someone. This does not sound like something within my capabilities.

Where do you live?

Where do you live?

I am about 1/2 hour south of Morris, Illinois. I have been in contact with the Ottawa Bobcat dealer, but their mechanic seemed to be a young kid who was unfamiliar with my machine.

You are a long ways from anyone that I can recommend. I'll ask around….there has to be someone that can help.

Nothing like an 8 year old thread, with the exact issue one is having.
--Jackshaft pillow block & bearing. The part is a NLA from Bobcat. Part # 6515105 (Housing) LPS wants ~$62+40 for shipping.
Doing some web re-search it appears the industrial part UCF206-20 would be the closest matching cross-reference. Any engineering experts able to confirm/deny. (again Bobcat OEM is NLA) I'm looking for the pillow block housing specifically. Amazon has UCF206-20 for ~$20-40.

Alternatively. Used ebay parts or other photos show two cut out-outs in the casting ring which retains the bearing (N/S or E/W). Either outside face or inside face (gasket side) of some castings. Is this a design flaw? design feature?. My existing part has an external N/S cut outs. which allows the driven jackshaft to move up and down. Thoughts?
