Bosch 010 Distributor Rebuild

Just a note, these pictures were taken back in 2001 when I first started rebuilding distributors. I have upgraded all my tools and procedures since, including a Sun 600 Distributor Tester to ensure every one meets factory specifications. Goto http://www.glenn-ring.com/bosch to see current stock.


Here's what it looks like when I 1st get it.

This is the inside. Some rust but everything's there.

Here's the back. No condensor or bracket.

The Bosch bagde looks pretty good.

Remove 3 screws and the contact plate comes out.

Here's all the parts of the top section.

Now you can see the advance mechanism .

Notice the "fiber" washer. They're very fragile.

Now remove the wire retainer on the Distributor drive.

The roll pin holds the drive on. This has to be punched out so the shaft can be can be removed.

Pretty greasy. That's 40 years of oil and dirt.

Now you know why i rebuild these.

Here's the shaft and advance mechanism.
Notice where the 2 springs attach to the plate. You need to remove those and the advance will come apart.

These are the shims ans spaces that were removed. The ones on the left sit between the contact place and the advance.
The ones in the center sit between the adcance and the body. The ones on the right go between the body and the distributor drive.

Here's a close up of the advance weights. The are held on with small "C" clips.
Also note that they are to different sizes and must go back the same way.

Under the weights are small washer/spacers. Finally there is a very thin and fragile plate that needs to be removed.
If you are not very careful, it WILL crack.

Here's the advance totally apart.

Note the "C" clips and spacers.

This is the top section of the advance. The 2 springs do not have to be removed.

Another shot of the shaft and the bottom of the advance.

Here it is... totally part and ready to be cleaned.
I let the parts soak in a pan of parts cleaner and use a brush to remove the oil and dirt.
I use a bench grinder with a fine wire brush for the body and larger parts.
I use a Dremel for the hard to get to spots and smaller parts.

Here's everything all clean.

The body has been totally stripped and is ready for paint.

The inside is alittle cleaner than before.

The weights have been cleaned and i use a paper towel with parts cleaner to clean the spacers.

This is the order of parts for the points bolt

Here's the contact plate and the cap clips.

The shaft has been cleaned. I very carefully cleaned the fiber surface with a paper towel and some parts cleaner.

The bottom of the advance with the weights back on.

Here's the Bosch Distributor grease.

I apply some Bosch "Distributor" grease on the shaft and then slide the top of the advance back on.
It only goes on 1 way. You'll know if it's on wrong. The springs get but back on the holding tabs.
Test it by pulling the weights toward the outside and the top section should rotate.

I put masking tape over the Bosch badge and use a razor to cut around it.

I also cover the the body so i don't have to be too careful.

The body is painted and i don't have to worry about the badge. It won't be that shinny once it dries.

Now put the wire retainer back on.

Starting to get there.

The contact plate drops in and 3 screws hold it in.
Make sure the longer distribtor cap clip is on the left of the badge or the distributor cap won't fit.

A little grease on the points shaft.

Here's points installed along with the bolt.
You have to make sure that the bolt doesn't contact the body. I use a meter to double check.
Don't forget to grease the distributor cam or the points will wear quickly.

Well... here it is.

The inside looks alot cleaner then when i 1st got it.

I added a condensor bracket so the correct condensor can be mounted.

Here's my current collection. The one with the black cap is a 019 and the one on the right is a German 009.


Sun 600 Distributor Tester.

I hope this helps you with your rebuild. It takes about 4 hours of work to completely disassembly, clean and reassemble the distributor.

I can restore your distributor or sell you a restored 010/019/022 distributor outright. Goto http://www.Glenn-Ring.com/bosch to see current stock or email me for details.
