rebuilding TRF501x diffs

[delanobe]

I'm rebuilding my diffs but and was wondering what grease to use??

Some say the green slime stuff is best or Tamiya ceramic grease?

What to use?

Thanks

Don't use either of those greases! The ceramic grease is meant for gears I think, and the slime is for shocks - not sure if it will work but I wouldn't use it. I wouldn't put either of those anywhere near the diffs.

I use Tamiya silicone grease, the clear stuff - it's some of the best I've used. If you don't have any or can't find it (finding Tamiya stuff can be hard) then pretty much any silicone grease will be 'ok'

For the thrust bearing I use anti-wear grease (again, some came in the kit)

when i ran the tamiya, i used associated clear on the diff balls and black on the thrust bearing.

I use tamiya ball diff grease all the time.


I also get to about round 2 of the first day before my diff goes all gritty though, so maybe I'm an idiot....

From what Ive learnt,the dark grey-'MOLY' type grease is good for metal to metal thrust race type applications.As for diff balls which fit through nylon diff gears-only use the clear-'BALL DIFF' type grease.Ive tried the reverse and the diff gear gets chewed up real fasr with the MOLY.

Jason,

Never use "moly" grease in ball diffs. This grease is not designed for high shear pressure use - great for metal bevel gears, but not for ball diffs.

You should always use a silicon grease for the main diff rings and balls. For the thrust race, the Tamiya Anti Wear grease (as Jimmy said) will work well, as will Associated "black" grease or old Losi "red" grease.
