Can anyone tell me if there might be a place in the GMC archives I can find
out how to do this?

Actually, I don't even know how to find the archives.

Thanks

Its pretty easy to do. Disconnect the battery lead to the starter. Then remove the battery cable from the starter solenoid. Then there are just two bolts holding the starter to the Onan housing. If you are down under the side of the Onan you can see it very clearly. You do not have to remove any shrouds.

To remove the Onan starter:

1. Disconnect the battery cable or open the disconnect switch if you have one.

2. Remove the one nut holding the battery cable to the stater solenoid. There also is one more wire on that same stud that needs to be removed.

3. Remove the single small wire to the starter solenoid. It is a push on connector.

4. Remove the two mounting bolts or nuts holding the starter in place and slide the starter in towards the coach. I believe it is a 9/16" socket wrench.

That's it. You are done.

It took me longer to type this note then it is going to take you to remove the starter. (I'm a terrible typist).

While you have it out you might have it rebuilt, I just had my Onan 6K starter rebuilt with new drive gear and bushings by local Onan authorized repair center for 54 bucks, they even put machinist bluing on the drive gear so I can check the teeth alignment with the ring gear on the flywheel. Wish I would of done this long ago, like new! If I had done it when I replaced the broken mounting bracket (3yrs ago) would have saved me 15 minutes.
Quite easy job to pull and re-install.

Yes, I just had mine rebuilt locally. New bushings, brushes, solenoid and drive gear. They also turned commutator. I did not have them paint it when it was done. Total cost was $50.00. Hopefully it will last another 30 years.

Ray,

Here's a link to where you can download Maintenance Manual X-7525 for
1975/1976 GMC Motorhomes.

http://www.bdub.net/factory-manuals.html

For MM 1975 / 1976 X-7525 click on:

http://www.bdub.net/manuals/X7525/index.html

For 1976 Supplement X-7625 click on:

http://www.bdub.net/manuals/X7625/index.html

While you're at it I would suggest you download:

For Parts Book 78Z Covers all years click on:

http://www.bdub.net/manuals/parts/index.html

Once you've downloaded MM X-7525 here's where you can find the procedure to
remove the starter:

Section 24C ONAN MOTOT GENERATOR
Page: 24C-30
Paragraph: STARTER REMOVAL

I would suggest that you consider buying a cast iron starter bracket from
Ragusa as they have a tendency to crack:

Click on Engine Items to find Part Number: RV-04 @ $45.00
