How To: C15a Wire-3 restoration

[Jordan Baker]

I was looking at those kits. I wish the Chevys of the 40's was available.

This model after looking it up in the C15a-4 Illustrated Parts Catalogue is Delco Remy generator assy 1102695. It has a bearing on the drive end and a bushing on the commutator end.

Tear down of the generator continued today. Everything has been disassembled and the major parts parts sandblasted. The commutator was cleaned up on a lathe. The field coils will be re wrapped as well. All of the small screws are being soaked in parts cleaner then in evaporust to clean them up. I'll be ordering a new fully sealed bearing for the drive end. I just need to find a couple of smaller bits and I should be good to go again.

Hi Jordan

There are a number of NOS field coils available as new kits or old stock on Ebay around $30.00.

Might not be a bad idea to look for a spare one if you are determined to stay with 6 volts. A lot of the fiddly parts are common to Delco for tractor so a local farm tractor dealer....particularly the ones dealing with antique tractors will have loose parts that you can compare without using the darn computer.

I got brushes and springs for a few dollars from a Massey dealer which is familiar with Delco/Massey usage..... same for starters and distributors, bushings, points, caps and rotors.

Keep it sparking.

The past day or so has been spent working on the starter. Broke it all down to its components. New rebuild parts are ordered. The casing, front section and end plate have all been sandblasted and painted with semi-gloss black as per the originals. Once back together this should crank the engine nicely. One unfortunate discovery was that the one main connection on the field coil was broken. I'm checking with the company I've ordered the rebuild kits from to see if they have matching field coils. If not I'll go the eBay route and try and find a matching one.

I'm always amazed at just how many individual parts go into making the vehicles we all love. An example being the copper stud in the starter. It's simple in what it does but takes 8 pieces to do it.

Also you can see where the copper band snapped/corroded away on the field coil. They should be easy to make match last part I noticed was the starter lever. The little contact points were rather heavily worn. I'll be checking the other starters I have to see what condition they are in. If all are similar I figure I'll just rotate them a bit to an unworn section.

Shaun, this was the link I used for rebuilding my jeeps generator when it had a total bearing failure. I still refer to it today as it is a great step by step.

Finally started in on rebuilding the starter today. Brand new field coils were used along with NOS field coils screws. Its amazing just how hard these screws are to get out and then back in again. For removal I made up a tool to use in my impact air gun. Worked great for getting them out. However it wrecked the tops by chewing them up. For getting the field coil shoes back in just as tight I use the long nut and the two bolts as a kind of screw in wedge. I screw the screws in as tight as I can, then place the wedge in and turn it so it presses against both shoes. I can then normally get another 1-1/2 to 2 turns in the screw.

The copper leads were then pushed and pulled into shape and soldered into the copper stud.

Nice work, Jordan.
