Melted diff gear on 2wd...

Adam F · #1 22-09-2013

Anyone had any problems with melted diff gears on the 2wd cars? (SC but same as the other 2wds)

Mine has a steel idler if it makes any difference...

I've experienced this in a stadium truck with a ball diff many years ago, but never in a buggy. I put it down to the bigger wheels on the truck requiring a much higher torque than in a buggy to turn the wheels.

Back when I use to run my rear motored car I always chewed through plastic diff gears with my steel idlers. So we changed to a Kevlar diff gear and we never had a problem again

I think this is it but I'm not too sure, check will Alec he will know

Did you melt the gear teeth or where the diff balls sit?

The teeth themselves, had put some metal gear grease on them but they lasted less than one round..

Car was second hand, so will try a new gear and see how it goes...

Not seen that yet, try this diff gear http://www.smddirect.co.uk/tu0257-pom-gear-52t-2wd-1265 and also I wouldn't use metal gear grease myself I've always found a few drops of shock oil on the gears works well
