I haven't touched my TC5 since the last rebuild and now that my novak case is finally going to get here, i am looking it over again. It seems like the drivetrain is binding up a little due to the belts being tight. I am running a spool in the rear and a one way in the front. If i pull the spur, both axles spin freely but if i install it and connect the belts, it seems alot tighter than it should be. Any ideas?
