Grinding sound on full acceleration
Hi everyone,
I just finished upgrading and repairing the transmission in my cougar sv, but something doesn't seem right. When driving slowly I get an intermittent 'click' sound, and at high acceleration a grinding/slipping sound. I stripped back the entire transmission. Cleaned everything Replaced the diff screw set, upgraded the diff balls to CN Changed some bearings to ceramic ones Changed the idler Altered the internal ration to 1:2.8 with the appropriate gears Changed the slipper set, and went to a 80T Changed the pinion to a 23T The diff is tightened as tight as possible, and then undone 90 degrees as the manual states. The slipper spring is very tight (maybe too tight?) Gears meshed at the pinion very tight, with slip of paper between. Everything greased as it should be - Moly in diff, silicone in parts where the manual says. Ceramic grease on other gears The motor is a 9.5T Any ideas what the problem may be. Is it overgeared? maybe going to an 81T or reducing the pinion ? Thanks heaps for any advice Cheers! |

Problem solved.
It turned out my allen key driver was slightly loose resulting in reduced torque when screwing the diff tight (hence not tight enough). When I used a plain allen key I was able to tighten it several more turns so I was unable to rotate the diff by hand. I also backed off a little on the slipper spring. Now everything is running sweet, nice acceleration without noise, wheelies with full power. Thanks anyway Cheers! |

Undergeared if anything.
