Starter for Perkins 4-108

[RJ86]

Hello all:

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.

Thanks-
RJ

Don't know how many teeth, but I installed an Argentinian starter on my 4-108 a few years ago: Half size and half the weight and plenty strong to spin the engine at a good clip.
Paid around $228.00 in Fort Lauderdale at East Coast Battery.
Marine Batteries, Alternators, Starters, Rolls Batteries, Delta Batteries, Etc.

Much easier to install than the Delco starter due to less weight and size..

I could dig up part numbers or some details, but try to Google Compact starter or Argentinian starter first..
(I Yeah, I know Argentine is best know for their Tango and not for starter motors, but this one is good)
