How to prep big little parts

sflem849 · Feb 4, 2012

I am starting to take all the big things off the engine and I am wondering what to do with them. How do you prep a generator, water pump, injection pump, etc for paint? Also, how do you keep track of all the bolts and get them painted? When just working on a tractor I usually screw them back in the hole they came from. I don't see that working out well this time.

A sheet of corrugated cardboard and a magic marker.
Poke holes for the bolts and mark there purpose on
the back of the cardboard. If you paint the heads while in
the cardboard they will get nicks when installed.
Cleaning and prepping components takes time, and a
tooth brush as well as a small wire brush. then
dry, sand, mask, and paint. Remember that at IH
they were painted when assembled (even the belts)
cardboard tubes on the axles, cover on the gauges,
and steering wheel. Jim

I put all my bolts and misc hardware into zip lock bags and label the bags for each part they were removed from. All lock washers get replaced with new ones. I put never seize on any bolt over 3/8 when assembling.

The bolts I repaint are usually cleaned with a wire brush on a grinder and primed and painted by hand and stuck into holes in a piece of plywood, etc. By the time of assembly I have usually forgotten what goes where and just look for them. On parts like a starter or generator I might just sand the body or use a wire brush on an electric drill as such parts are too small for an angle grinder. I tape off the label. From there they are cleaned with wax and grease remover, primed with epoxy and painted with urethane just like everything else. The bolts are touched up after assembly, or sometimes replaced with cadmium plated bolts, if I have not already used several cadmium plated ones, as I don't want too many of them. I try to make the shiny bolts blend in with rest of the tractor. I keep the decent unused dot heads in case I want to use them for something else.

I use Janicholson's carboard method, however, remember to make your notes as to where a bolt is used on the BACK side of your cardboard. That way, when you paint the "head" side of the bolts, your notes are still there.

I use a hybrid of Jim and CNKS, but then they both helped me learn so that should not be surprising. I take cardboard boxes and poke holes with a screwdriver, inserting bolts in holes. They are first cleaned on a wire bench grinder. I map the position of the bolts and where they come from on a pad of paper because you will paint over your labels on the cardboard. On reassembly I use the pad as a general guide and a parts book for exact sizes and just make sure I get the right sizes in the right places. Damage is minimal with good paint on a clean surface but I do use a small paint brush and a bit of paint in a cup to touch up the small dings from the wrench.

Nuts/washers are laid out flat and painted one side and then the other or replaced altogether with new that I have pre painted. I don't much care for wasting a lot of time on rusted nuts.

Cotters and other odd parts are either hung from wire or laid out flat and frequently just replaced with new unless they are an odd size.

My best friend is my parts book.

Thanks for all the help guys. Just thought I would post a couple pics I shot yesterday. Now that I have a decent cell phone camera I have been trying to take a lot of pictures along the way. That way I can document what I have done for a super cool photo album and I might have a couple clues on how to put it back together. This will be the first tractor I own that is actually red so I better do a good job!

I already have the water pump and fan assembly off. I will work on the hydraulic pump and distributer today. I would guess the machine shop will want the oil filler and oil filter off??? Then off to the other side for the injection pump and filters. I would guess the machine shop will need the cross over shaft and throttle stuff off???

How far should I go on the steering stuff? I plan on popping the lid off to look for problems in the rear end. I have never heard this tractor run or drive so I am a little scared I will get it all painted up and then have to rip into it big time.

I also use the "holes in cardboard" method. I put the small stuff like nuts and washers on a piece of waxed paper to mininize sticking.

Concerning your questions about the cross shaft and other attachments, I took them all off. All I left was the fan pulley and stuff behind it. Per recommendations of the folks on this site, I took off the oil pan and oil pump, got a tire, stuck the block on it, tied it down, and off to the machine shop.

Here is what happened today. Got all the stuff off the motor and shoved the bolts in cardboard as mentioned. I did write on the top, but I figured I would make a new and cleaner cardboard when I painted. I am asking for contamination using this one.

I really wish I would have gotten to pressure wash this machine VERY good before disassembly. I bought it in pieces with open stuff on the motor and I was a little scared of contamination. If I had known back then that I would be doing a complete rebuild I would have just washed it. I covered up the top and just washed the easy stuff, but it didn't do much.

I am no looking forward to taking the set screw and pin out. That job didn't go well on parts motor number one. I do have great news about parts motor number one! It is a 4.5" motor so I can just bore the pictured motor out and have the big bore!
