What to do about grease in track rollers

[Ed Miller]

My OC-46 small repair job continues.   I got the track frame off and and am working on repairing the broken studs and bearing caps that hold the track rollers in place.  Parts are on the way from Zimmermans.  I noticed that all the rollers are filled with grease.   I have an oil gun coming with my part order.  Should I just shoot some 90 weight oil in there or use something lighter to clean the grease out and then add the 90 weight.  Any suggestions?

Thanks
Ed

50 weight non-detergent engine oil is what is recommended. I would think on a hot day it would thin out the grease.

Just to let you know. . .I have been pondering that question for awhile as well.  Thanks for the answer Blake.

If it was me I would use the John Deere corn head lube. Deere used to use oil and they went to it. Flows at temperatures low enough for me.

Ed, I went back through some of the older posts on this forum, and found a lot of good info about track and transmission lubes when I had my OC-46 apart last fall. I had the same problem of someone using grease on the rolls. I just socked the 50wt non detergent to the ones that I didn't have apart untill I had plenty of oil coming out of them. Ran it, and lubed it some more. The key info I found out on this site, is not to use any type of hypoid gear oil... 50wt non detergent motor oil or 90wt mineral oil is what you should be using.
