WTF am I doing wrong, I've never had this problem, could it be the 5.5r bolted in, or am i just crap at adjusting this diff? |
It's not your motor. I have been racing a Durga with a Novak Ballistic 6.5T and have had no problem with the diffs.
A chewed up pulley has almost always related to the diff being too loose. Other possibilities are:
1. Wrong grease used to build the diff. Both the thrust bearing and the diff plates and balls need a coating of -diff grease only-. Other greases allow the diff to move too freely and can cause them to slip and grind.
2. Diff build backwards. This has been a hot topic ever since the DB-01 was released. A diff built backwards will loosen very quickly
3. Thrust bearing has failed or is jammed up.. A bad thrust bearing will prevent the diff from properly operating and result in similar problems to the diff being built backwards.
Hope this helps.
