Hi all, I have a Typhon 3s (but this is probably applicable to all the 4x4 3s models).
TL;DR is that my stock pinion is DESTROYED after tightening it and with a steel spur gear.
Longer version:
Recently got the Steel 57T spur gear assembly. I slightly loosened the slipper clutch screw even though it’s supposed to come pre-set but figured just in case. Ran it a few times and things seemed ok. I disassembled the car yesterday to fix something and checked on the pinion and spur gear. Noticed 1 small chip in the pinion and then also noticed that it seemed a bit loose so I put thread lock on the small set screw and tightened it all the way. I wasn’t sure how far to push it toward the motor but went by where i saw a mark already. It seemed ok and definitely set in place. Reassemble the car and took it out today and within 2 minutes heard metallic grinding. So that was the end of my bash session sadly. Got home and took a look. The pinion is destroyed. Spur gear looks perfect though. What did I do wrong?
Is there a better pinion? Was I not supposed to over tighten it? Did I push the pinion in too far toward the motor? Did a pebble or dirt just get in? How do I avoid this happening again?
Thank you!
