Can you help with starter identification?

[cruiser]

I have a spare starter for my slant six powered 1974 Duster, and am thinking about rebuilding it. However, if its not the correct one for my car I'll keep looking for a better one. Here are the markings on the starter:

Molded into the aluminum case on the side adjacent to the mounting ears:

67 KOP
2095219
1 D/C/P/D (Chrysler/Dodge/DeSoto logo)

At the top of the black motor housing barrel:

4 975


Any and all ideas welcome. Thanks!

The 209 number is probably the casting # & I would guess that is late 50s/early 60s. If there was no reason to alter the casting, that # could have been continued for many years.

check mounting lugs pinion tooth count and pinion diameter and the clocking of the main body in respect to mounting holes with a known working starter....

if it has 25mm 9 tooth pinion..... its a direct drive gen II "street" hemi starter from the first year of manufacture i.e rare as hens dentures in the general scheme of things (worth a bit)
or its a 1960?61 slant 6 starter

both are kinda specific to those applications

i.e won't work on your car as standard. but may be viable on an australian mopar like mine, hence I know (enough to be dangerous) about them


proper one for your application?? dunno hence the pointers about tooth count and "clocking" above.

in general from early 60s until the 90s the mounting was the same
the radial distance from the centre line of the crank and the number of teeth on the ring gear dictated the pinion configuration
the depth of throw of the pinion gear was much the same

obviously there will be special cases

But you can fit a starter off a 1990s 5.2 v8 to many things from the early 60s onwards which adds weight to the case of there being reasonable standardisation, regardless of the rest of the electric motor configuration.

How about a photo of the starter? If it's the typical gear reduction starter used from the '60's to '80's, they pretty much all interchange. If your concern is matching casting numbers, that's a different story. There should be a "bullseye" date code on that cast part. Maybe that's the 67 you see?

The Chrysler gear reduction starter was introduced for the 1962 model year. 2095219 is the casting number of the aluminum housing used on 1962-1969 starters, part numbers 2095150 and 2098500. "67" denotes the housing was cast in 1967. "KOP" is likely "KCP" and is a foundry marking.

A matching armature housing should have the part number (2095150 or 2098500) with a date code, and possibly the name "CHRYSLER". "4 975" on the armature housing does not sound like a Chrysler stamping. It is not the correct format for the three digit date code. It could indicate something else. The armature housing might be an aftermarket, or other service unit.

Your starter is possibly a mix of parts from a mass rebuilder. There were several revisions to these gear reduction starters from 1962 through 1987 and rebuilt starters can have a mix of some parts that interchange from different models. Markings can vary and can be hard to read if the housings have been blasted or tumbled. Housings and internal parts were also available from aftermarket sources with differing markings. 1970 and later starters can be quickly identified externally from 1962-1969 by the presence of the two bolts and nuts attaching the brush holder to the different aluminum housing with provisions for the bolts.

An original 1974 225 Slant Six starter is part number 3755900. Casting number of its aluminum housing is 3755259.

That's the pinion housing for a '62-'69 starter. Originally it would have been mated to a motor housing stamped 2095150 or 2098500.

The pinion housing and brush plate were redesigned for '70; depending on your car's build date you're looking for a pinion housing marked 2875553 or 3755259, and a motor housing stamped 3656575 or 3755900 (respectively) if you're trying to be dead-on-balls, numbers-matching correct. But there are a bunch of other motor housing stampings that originally got mated to a 3755259 pinion housing, too, if you're not worried about a show judge deducting points because your starter motor doesn't have the correct number stamped on the motor housing.

Thanks to all, especially Slant Six Dan, who weighed in. Very helpful info all around!
