hi can anyone tell me if hongnor do a spider diff or heavy duty center diff i keep blowing my center diff been running picco p3 28 motor but changeing to a 21 now to see if that helps
cheers in advance

Genius

I dont think hongnor has anything like that. The hobao spider diff should fit but the gearing is different and its not interchangeable. Iv been using a .21 and a .28 engine on my CRT for the past year and a half, never had any problems. Are you referring to the internal gears?

yes its the 2 big gears in the center diff i have shimed them but it still does it but i run on grass with badlands i think this could be part of the problem aswell cheers

how do you have them shimmed that has alot to do with the problems

Genius

yeah check whether all the shims are still in place behind the gears. Check the cross pins for wear and the diff case where the pins slide in. Play around those areas can really put strain on the whole assembly. Depending on how long you have been running your truck you can expect the gears to wear and develop a sharp edge.

thanks for the tips i have put alloy diff cup on the center and new gears shimmed up 2 shims on all 4 pins hope this will do it this time
cheers

Th Hotbodies LSP diff gears are steel and drop right in, you can find complete diffs on e-bay and just install your big spur gear on it, I run the whole HB LSP diff in the center of my Jammin BCE PJX , i beleive the hellfire internals will work too.
