center diff in rc8t ?'s
 

do you have to change gearing in center diff if you change spur gear?

i put on the 46t spur gear and had a GREAT time with the rc8t...i love this truck...it actually ran cool but after about 15 minutes it heated to 150 so i let it cool for a while and ran the Dual BL!!...GOOD TIMES!!

when i put the diff together with the new 46 gear i did not install shims...after 5-10 minutes i noticed center diff crunching a little and installed 3 small shims...it seems to be smooth now

1)is my diff beat?
2)i have several UE spider 8's...will they work and should i install one?

Gorgeous truck! Personally I would take the diff apart and inspect the gears for damage..

1. Open it up and check the bevel gears.
2. 8 spider ofna center diffs will work.

would someone mind explaining a little more about this original question. i also have a BL RC8T and i run the 46t spur gear but i never changed a thing to my center diff. everything seems smooth and sweet. should i have changed something in the diff when i went from the stock 54t to the 46t????

No, unless the diff bevel gears themselves are broken.

i had the same question RU james...i think my gears are fine...no teeth missing...might have slight wear but hard to tell...i will run it and see if the CRUNCH is gone!!

hey LITO,are the UE spider8's better than stock diff?
