Dadddio Posted January 10, 2017 Share Posted January 10, 2017 I am in the process of replacing the input shafts bearing and countershaft bearings in my 5 spd. My question is can I clean the gears and syncrose while I have the case split. They are pretty nasty....sat for 20 years. What could I clean it with? Could i use brake cleaner?

Nelsonian Posted January 10, 2017 Share Posted January 10, 2017 Evaporust is a good starting point. It is safe on all metals and hands body as well as environment. Quote Link to comment Share on other sites More sharing options...
Dadddio Posted January 10, 2017 Author Share Posted January 10, 2017 Thanks Nelsonian. It's not rusty at all. It sat empty and the oil that was there has kinda turned to a thick sludge. Quote Link to comment Share on other sites More sharing options...
JoeK Posted January 13, 2017 Share Posted January 13, 2017 Paint thinner works pretty well Quote Link to comment Share on other sites More sharing options...
grannyknot Posted January 13, 2017 Share Posted January 13, 2017 Spray can carb cleaner, paint thinner, Varsol, (just not water based cleaners) and a old tooth brush, blow it out after with compressed air, then oil it again. If you are not completely disassembling everything and feel there is still gunk that you didn't get you can run ATF as the tranny fluid for a day, then drain and fill with proper oil. ATF has alot of detergents and will scrub everything nicely, just don't push it, no hard shifts. 1 Quote Link to comment Share on other sites More sharing options...
Dadddio Posted January 13, 2017 Author Share Posted January 13, 2017 Thanks for the input. I ended up using 50/50 ATF and diesel fuel. I figured the detergents in the ATF and oil in the diesel would work well together. Seems to have cleaned very good. I still may run some ATF through it anyway.
