Hello - I own a 1950's vintage Oliver OC3 and am hoping to get some tips on upkeep. Last fall I discovered a local mechanic who worked on them and had a worn sprocket replaced because the track kept coming off, He also checked a few other things as it hadn't been used in a couple of years and it seemed to run fine for the few times we used it for removing snow. The other day when in gear the clutch started making a squealing as it was released. When pushing the clutch in the noise went away. It's not slipping but could this be a bearing problem or need of lubricate? My knowledge of tractor mechanic is very limited... I'm in wood. 😉

I notice that there is not much activity on this forum about OC3s but thought someone might have some insight into the problem and whether I can fix it myself or have to get it hauled into the shop again. Thanks in advance.

Thanks! Now I have to revise my description of the noise. My husband said it sounded like squealing but I went out and listened yesterday and it sounds more like grinding so I'm thinking that it is the transmission and not the clutch. 😒 Not good... if it can be repaired it will be expensive.

Welcome to the forum. Grinding can't be good! I wonder if a splined shaft is striped? Do you have a repair manual?

Unfortunately no manual. I never heard the term "splined shaft"... is that part of the transmission?

Here is a picture of the Oliver OC-3 clutch disc. The hole in the center is splined to accept a output shaft with the opposite but matching splines to transfer rotation from the engine to the transmission....

I may have explained this poorly but it was just a suggestion as to what the issue could be.

Okay, thanks. Definitely will be an expensive repair job.
