Looking for the Diesel Starter for a D311--7S 8119 motor. Want to leave the pony pinion assembly on and mount the starter below it. Don't know if the solenoid would be a problem.

Are you looking for a conversion starter (solenoid engagement type) or an original inertia drive with remote mounted solenoid? Does the flywheel housing have provision to mount the starter?

it appears that there will be no room between the top of the starter and the pinion clutch housing as the 3 bolt plate is close to the housing. so i assume i need a remote solenoid to make the starter fit. I will use the pony for cold starts and the starter for hot starts when i stall the engine!
a 12 volt starter would be nice if available as i would only need one 12V battery for both starters

Well, those are nice thoughts but there are complications.
With the factory starter hole only an original type (comes as 24V) inertia drive with remote solenoid works without modification.
To use the 42MT starter conversion with the available RH helix drive and the special drive end housing the starter hole in the bell housing needs to be offset ground 1/16" and the DEH bolt holes drilled out to 5/8" size due to the fact that the available 11 tooth helical drive is 1/8" larger diameter than original. No modifications to the original pony clutch housing are required but the conversion starter solenoid will hang out the side to where the side covers will not mount.

There is a more involved installation that will allow side panel installation if you choose. You can study up on all this here.

dpendzic That is what I have on my D-2. It is a 24 volt inertia drive starter. I have two 12 volt batteries for the main engine starter and run the pony starter off one 12 volt battery. I also have a 24 volt charging system to keep the batteries charged. Everything sets in far enough so the side panels will fit.



I have an extra 24 volt inertia drive starter if I can find the drive end for it if you are interested. Don't know what it would cost to ship but that I all it would cost you. (Claney's Price)

Brian--that sounds fantastic!!! I'll add the second battery box and battery and worry about charging later on. did you get to find or fabricate your side panels yet? Wish we could meet up again at another spring fling!!

Dan I can't find the drive end for this starter, although I see they have them on E-bay. You will also need an 11 or 12 tooth right helical inertia drive. If you still want this starter send me an address and I will box it up and get it on it's way. I have just finished the left side panel for my D-2 and started cutting out the right side panel when my plasma cutter quit on me. I'll take pictures when I finish them. Let me know about this starter.
Brian

Drive end housings and inertia drives for the early starter are not commonly found on ebay. Drive has to be the one for D2, not D4/D6.

Brian and Pete--now i am getting a little confused--the 4U dozer is 1957--last year made but the replacement engine is 7S-8119 and i have no idea of the year--are the flywheel teeth different or can i assume i need what Brian said an 11 or 12 tooth right helical inertia drive? and if it can be 11 or 12 teeth wouldn't the pitch diameters be different?
I better look into the availability of the inertia drive before getting into this any further.

There is only one drive that is correct for the original D311 starter
Cat #1H2473 Delco #1919905
Only one drive end housing is correct for the original D311 starter

There is no interchange.
Your 7S-8119 engine is a late 1953 engine. Same as the original D311 with 93T flywheel.

Not until you go to the conversion (42MT starter preferred) do you have the option of 11 or 12 tooth drive but that's because you are boring the flywheel housing in a position to accommodate them.
