The starter (or more accurately, the solenoid, or maybe the pinion) is going bad on my 1979 Gulfstar
. I'd like to get a replacement, and rebuilt the old one to have around as a spare.
The user's guide shows part #NA000623, which apparently translates to a Delco 28 MT starter, replacements
for which are widely available. But some of these have 10 teeth, and some have 12 teeth.
The original Perkins
4-108 apparently used a Lucas M45G (direct drive) starter with 10 teeth. The "North American Accessoies' package apparently changed to a Delco reduction gear
starter, the 28MT.
But is it supposed to have 10 teeth, or 12? Does it matter?
I'll pull off the old starter, of course, and count the teeth on the pinion, but I wanted to have another starter ready to bolt on while I'm still bleeding and cursing after getting the old one off.
