New Method of Direct Electric Start

Hi Alan,
Looks pretty good.
I have a couple of questions.
Does the starter power up after engaging the pinion or before....no-load starter motors can spin up to 5,000 rpm or more.

I wonder about the starter motor itself. Looks like an old style 40MT motor when they had seperate solenoid and inertia drive. Those motors are pretty much becoming extinct and I am not aware of a modern equivalent.

Certainly better than the previous top mount version that ate pony clutches...I think.

Also, before everyone gets all excited, that would only work on the D318 or the D4600where there is ample room between the pony clutch housing and the governor.

Old Magnet, you'd have to ask Byran about that one, I just posted what he told me.
I like the idea for my DW10, since there is no room for an electric starter where the stock one attaches. Darn shame too, the hole is drilled in the bellhousing and has a bolt on cover already. Unless someone makes a 12 or 24 volt starter only 6 inches long! Too bad there is no way to mount one on the other side of the tractor....tons of room over there!
Electric start makes a lot of sense for a machine you are actually going to work, sometimes machines get the engines killed in places you need to get out of in a hurry! Not so important on a show machine!
Too bad no one makes a mini-starter with enough grunt to turn over a D318...I guess they isn't enough demand for a hot rod Cat yet! Car guys have it good....

hello alan ,have you looked at a air starter ,there are a few different one around ,only need a compressor then 😎 ,bruce oz

Hello Bruce, thanks for the information.
An air starter is a thought, although I'm betting size would still be a problem. Right now, my personal economy is very bad, it's going to be a while before anything I have gets anything done to it. The problem on a DW10 is there is only 6-7 inches between the face of the belhousing and the spot where the steering arm attaches to the steering box, which hangs off the inside of the frame rail. I'd have to go measure things just to see how much room there is, an offset starter like some of those pictures is what is needed.
So, for the mean time, I just seek information. I have a good replacement pony motor for my dead one, but direct start sure would be nice!

OK,
But you did ask if there were forseen problems.
I've seen some pretty compact hydraulic drive starter motors but then you have the hydraulic source to contend with.

Old Magnet, I sent Bryan an email with your concerns. As soon as he sends me an answer, I'll be sure to post the information.
Now, if there's a starter with about a 2 foot shaft extension, then I could use it...or figure out a gear drive to get the actual starter motor up higher...too bad I'm not a fabricator...Alan

Thanks Alan,
Curious to see what the responses will be.

I'll say one thing, Bryan is quick at responding! Here is what he says..

Alan,,,The starter in the picture is a older 40 MT Delco..Known as the series 2.No problem getting parts... BUT I use the newer version anyway...The series 1, is what he is talking about ( with the inertia drive ) You engage the pinion first.. then crank the starter,, it will disengage it's self as soon as the diesel starts...Bryan
Just the facts, Jack.

Hope this helped,

Alan

Old Magnet is right, no way you can use this set up in the U model D2/D4's and the J series D2's also.😞
