D6 pony motor conversion to electric start

Daniel Hurlburt I have a D6 Model # 44A2539 series B. I'm trying to convert it to electric start.I found a Delco starter # in a d6 service manual and ordered it from a local auto parts dealer(24 volt)40MT starter. The pinion gear on the pony motor has 14 teeth. the pinion gear on the electric starter has 11 teeth and is smaller in dia.I can't find a electric starter with 14 teeth.has anyone else run in to this.can I take the pinion gear off the pony motor and have it installed on the electric starter.It seems to me that the 11 tooth pinion (which is smaller in dia.) will not mesh right with the ring gear an will take off the teeth.Has anyone encountered this before? Also a local rebuilder of alternators told me he can install a 24 volt regulator in a standard car alternator. Much cheaper than a standard H.D. one.All it will be doing is charging the battries back up after starting.
ozhank53 I am in the process of converting my D2 to electric start. I have the same delco starter, but with different drive - one that meshes with ring gear on flywheel. I am in process of cutting hole into clutch bellhousing and to drill and tap three holes to fasten the starter motor to. You need to disable decompression system for starting, and run starter for 7 seconds to build up fuel and oil pressure before opening throttle.

I am interested in the 24v regulator for car. alternator to recharge start batteries. I would be interested in more information.

R.W. Guy;s: CME Inc., out of miami,fl. makes a conversion kit ready to bolt on,without all the hassle, I converted my D8H a few yrs.ago with their outfit. If interested email, & I'll send you their contact info.Good Luck,Roger
ozhank53 I've finally found the time to finish the starter motor installation. I used a 92mm carbide tipped hole saw to make the hole with lots of kerosine. Drilled and tapped the holes. I found it best to remove the pilot motor starting clutch assembly. Tested this afternoon - wonderful to hear the motor run after nearly 18months!. Need to make battery mounting bracket where pilot motor sat, and modify the left hand side motor protection guard to accomodate the solonoid, drill hole for starter button.
Ken S I would appreciate any info on this conversion. Thanks

david young I would like the info on starter conversion. I can't seem to find the parts source. Thanks
Dan Hurlburt Starters are avaiable many places. It's a standard 24 volt Delco-Reme Srarter. Some important things.
1. Need a adapter plate made by Cat. This places the starter in the right position.
2. The pinion gear on the starter has to be strial cut to match the ring gear. You'll fine it to be 11 tooth Vs the size and teeth on the pont motor. The adapter plate compensates for the diffrence.
3. you'll need a 24 volt battery or two 12 volt in series.
4. you'll have to install a 24 volt alternatior.Get on with a built in voltage regulator.

Converting it was the best thing I have ever done.

CATMECH they changed the ring gear on the main engine to a straight teeth when they put the electric starter on. you have to replace the angle cut gear.

Jerry Zahradnik I am restoring a 1949 John Deere Model R diesel tractor with a pony motor. The pony is a 2 cylinder opposed piston engine. I am told that this engine was either manufactured by Caterpillar for John Deere or was made by the same supplier that made the engines for Caterpillar. Does anyone know where I can find new or used parts for the pony?

Clyde Leitold To whom it may concern, Some things to think about. I am planning on trying to make a deal on a d6c in the near future. It has a standard shift, no big deal to me and it starts with a pony motor. While i'll admit it is nice to jump up in the cab hit the preheat and start the engine. Lets think for a minute. Cost of a fairly expensive starter. Much bigger and more batteries, probably an alternator with much higher output. gauge fuse and all the retro fitting. You do it or the cost of somebody else doing it. If you pony motor is in good shape go with it. Maybe it would be cheaper in the long run to rebuild the pony motor. Once these machines are up and running you don't usually shut them off until you are finished using them. Clyde
Clyde Leitold Gentlemen If your pony motor is in rough shape maybe it is better to do the conversion. But if not maybe it is better to leave well enough alone. If your main motor is in good shape and the pony motor starts and runs easily, once these machines are up and running you you usually let them run until you are finished using them right? By the time you are totally finished with your retro-fit how much does it really cost. Just something to think about. Could somebody please tell what it really cost including labor? How much are these kits? I'm dealing on a D6C with pony motor and a standard trans as we speak. "An Old Iron Greeting" Clyde
