While I am rebuilding and inspecting my gearbox… gears, bushings, bearings… I find most gears have some pitting at the pressure point areas where the corresponding mate runs. I just wanted to get the 2nd gear upgrade for my 72 Combat which bring the gear closer to 3rd (the ones with the Groove markings) but after I did a thorough cleaning with my ultrasonic tub and then inspecting all the gears carefully they all seem to show Brinelling. Going to a belt drive system will alleviate this I hope. I will end up replacing the entire set with new. But here is my question. Has anyone tried using cryogenic metal treatment to his or her commando parts? Am I way over the top or is this affordable and worthwhile. I know this is done in racecars and industry. Your thoughts on this if you have used this treatment.???
