Machspeed Posted January 21, 2021 Author Share Posted January 21, 2021 Don't shy away from painting your alternator, John. Just mask off the front shaft and the regulator/brush holder on the back. Also be aware that it grounds through the case, so you might want a star washer that can get through the paint and get a good ground. Most 3G alternators have an unused threaded boss on the rear. This can take a ground wire directly to where the battery negative bolts to the block, if you like. Good points, Jim. I'll may spray bomb the sucker....lol! Thanks!

kramttocs Posted January 21, 2021 Share Posted January 21, 2021 Good points, Jim. I'll may spray bomb the sucker....lol! Thanks! Sounds like another reason for you to get into powder coating I've never attempted to take one of the newer ones apart or googled how to rebuild them but the stock master cylinder is a snap. Apples and oranges perhaps... I haven't used the paint you guys have mentioned but have used Eastwoods booster paint and their cast aluminum paint. Happy with both.

That’s funny, my first thought was prep, primer and paint. Works on aircraft. I thought you wanted pretty aluminum! Link to comment Share on other sites More sharing options...
Rembrant Posted January 21, 2021 Share Posted January 21, 2021 Was wondering if Fluid Film would address it? Basically just wipe it on. Man, that stuff is great on steel parts and bolts. I've wire brushed some bolts and stuck them in a container overnight, wiped them off and installed them. No rust yet. I'm a big fan of Fluid Film as well, and it certainly wouldn't hurt to wipe it on. I will probably do the same. Here is the aluminum master cylinder out of the 1995 F150 that I junked for the frame for my 1980 F150. It appears to have been fairly well preserved under all that gunk. I just cleaned it up last night. It seems to be in OK condition for being 26 years old. Piston cups and bore seem to be OK. It was pretty dirty though, inside and out. Would I be crazy to assemble it and use it as it is, or should I just buy a new one and be done with it? Comments good or bad? Link to comment Share on other sites More sharing options...

Might see if the plastic will stand up to brake cleaner and clean the inside of the reservoir. Link to comment Share on other sites More sharing options...

Would there be any issue with cleaning the reservoir out with water and degreaser, as long as I let it dry out well? Link to comment Share on other sites More sharing options...

Gary Lewis Posted January 21, 2021 Share Posted January 21, 2021 Glycol fluids are more like antifreeze than they are like oil. So, you are saying not to use water and a degreaser? Would brake cleaner be the thing to use since it is designed to clean brake parts? Link to comment Share on other sites More sharing options...

Brake cleaner is NOT to remove brake fluid, it's to remove grease and oils from surfaces that you handle, before that grease/oil contaminates the friction material. There are plenty of YouTube or other online tutorials for cleaning your coolant overflow reservoir. The same sort of peroxide-surfactant combinations will work in the poly brake reservoirs.

Is this sorta what you mean? Do you know of a better one? Link to comment Share on other sites More sharing options...
