I have a d2 5u that I use for snow and odd jobs, and the pony is starting to show slack in the main bearings. Not end play, but side to side. Makes me nervous to run it! I am wanting to convert this to a direct start. I am wanting to know if anyone has machined the starter hole out in the bell housing, if you made a template or just by measurement. I have looked into the conversion that takes the place of the pony, but I would rather have that spot for the battery.

Is it a special series of starter?

Also, is there lines on the inside of the bell housing so you can machine from the inside out? Any thoughts on this project would be great, thanks.

Why not just put a set of bearings in it?

Some one must have a stash of bearings? I don't seem to find any. I have contacted people that used to work on these, and they gave up trying to find parts. I fear the journal may not be good either. Besides the point, factory, the last d2s had a direct electric start. One on machinery trader right now. Sounds like most of the older direct electric start 4 cylinders were in a generator or other applications. If I could find a different bell housing, I would. Maybe one of you guys has the bearings? I could take the engine off and have you inspect it? Thanks

There's a template you can use listed in the stickies up top. The holes can be drilled in-situ - remove the side covers for access. The pony main bearings are simple plain bushings that can be made very cheaply by machine shops. I've had them made for $30 out of oilite using stock that was already pretty close to the id and od required. This enables you to make the id suit the journals (although I'd recommend turning them down to remove egg and taper. Mark the dowel hole location with the bearings and crank assembled, with the gaskets in place, so you can set the minimum end float. This is a very simple and cheap process for a machine shop.
Edit: I can't find where the template instructions are as the stickies have been rearranged since the last time I paid attention to them but someone here will point you in the right direction. You'll just need a half-inch drill and a hole saw for the big hole.

Think I am correct in saying that the very last 5U had a pony. I stand to be corrected. Not that direct wasn't an option

Yep---my late model 4U (1957) has a pony, but also a plate for DES.

Thanks Neil. We don't have machine shops around here that will mess with things like that. It does sound simple. I have not had the pony off of this tractor, to see what else it might need. It runs fine, just don't watch the flywheel!

What are these stickies you are talking about? Are they old newsletters or cat bulletins that told how to do the direct starter part? I was concerned that it is quite thick, that I may have to mill it out. I want to see what this is. I have several heavy pieces around with a big starter, just a matter of which one cat specifications wanted for it.

Thanks for the messages guys.

Well, just keep the oil up to the top mark and replace it more regularly than you think you should. It's only a quart. The stickies was a set of posts at the top of the discussion page (see the first word in the name of the post) that stayed at the top even as they aged with frequently requested information, including how to install direct electric start. I don't know where those posts have gone now but if you use advanced search with terms such as "direct electric start template", you might find relevant posts.

Hi Team,
as i have said before, the SEARCH Function on this BB is very frustrating to use due to it being hard to find your searched preferences on. Can anything be done as we are getting sick of continually repeating common asked topics data on here.

SO,
here is a link to OM's site. https://sites.google.com/site/oldmagcat/home/getting-started
Hope this helps.
Cheers,
Eddie B.

along with many others I converted my D2 to a starter motor. Depending on your climate, it is definately the answer. search my old posts - and others. it's all been done before.

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
