J450n Posted December 20, 2011 Share Posted December 20, 2011 I have to question the sealed diff idea, If the diff was in fact sealed the the drive cups wouldn't spin, I wonder if o-rings behind the cogs on the drive cups would make a better seal. Mine didn't leak straight away, everything seemed fine until the following morning where there was a blob of oil on the workbench, and the bottom of the gearbox was coated. Pulled it apart again and the diff was nearly empty. The oil Had leaked past the drive cups. Quote Link to comment Share on other sites More sharing options...
stretch Posted December 20, 2011 Author Share Posted December 20, 2011 What wt oil was that using mate? Quote Link to comment Share on other sites More sharing options...
J450n Posted December 20, 2011 Share Posted December 20, 2011 it was 15w50, not specifically for rc cars, just didn't want it to run dry and end up a shattered diff, But I've tried all sorts and it all leaked, the 5000w lasted about three trips out, about twelve hours in total. But much happier since I switched back to grease, I think oil in the diff is better suited to racer's who should be checking there diffs after every meeting, and top up/refill as required.

notfast Posted December 20, 2011 Share Posted December 20, 2011 I use team associated black grease from ms. Packed the diff with the stuff and had no leaks. Sure it's a little stiff to begin with but it soon smooths everything out. 1 Quote Link to comment Share on other sites More sharing options...

stretch Posted December 20, 2011 Author Share Posted December 20, 2011 (edited) I reverted back to grease (Red Teflon) in the diff and the problem went away, I didn't pack the diff with it, just smeared the cogs, and did the same with the gearbox. it's now back to normal. you got a link to the stuff as I will try that if 5k doesn't work. Is it the same stuff used for cycling? weldtite Edited December 20, 2011 by stretch Quote Link to comment Share on other sites More sharing options...

RobBloor Posted December 22, 2011 Share Posted December 22, 2011 I can vouch for ToadzRC as well, for the bulkhead and/or other 'shineys' - Ive had one or two 'shineys' for my firestorm off them, pretty rapid delivery from the US. http://www.toadzrc.com/ Quote Link to comment Share on other sites More sharing options...
stretch Posted December 23, 2011 Author Share Posted December 23, 2011 decided to do my diff today and decided not to bother with oils in the end Diff wasn't too bad actually considering I've never done it before, there was a couple of blobs not touching anything though gave it a clean up using brake cleaner and compressed air to dry then a blob of Weldtite TF2 grease in one side Job done, now just to get it out and test it Quote Link to comment Share on other sites More sharing options...
