Open Road

Hi guys and gals:
Ever since I bought my 88 S4, one time out of 15 starts(approx), I get a screeching sound out of the starter. I did a coolant change and while in there, I checked the starter, to find the solenoid loose. I took out the starter, to find only one screw, and it was loose. I did not have the courage to take out the screw, to find the size of it. I had no idea, if the solenoid would come apart, and leave me with 4 pieces in my hand, and a set of brushes. So, I tightened it up, and was wondering if someone knows the screw size. I checked the WSM’s but that did not help.
Thanks for any help. Oh yeah, no more screeching now.
Another day under the car......

hi Don
its just the standard M6 X1 pitch
just a taper head version might be harder to find
cheers

Thanks so much, Phil. I left my belly pans off, but refastened everything back up, as I didn’t know how long it would take to find the screw. I should just go check out a starter/alternator rebuild shop.
All the best, and carry on with your incredible restoration.
