I have been reading Old magnets site and this forum and learning what I need to do, but I still need help.
I am tired of messing with the pony motor and would like to just push a button to get the bulldozer started.
I have a 1955 capapillar traxcavater 955a 12a952
How much does this conversion cost?
what starter and parts do I need to get? I want the easiest conversion.
thanks
Joe

Well, I'll tell you I am burned out on coaxing starter conversions.
I'll sell you a Delco 42MT or 40MT starter ready to mount for $700 plus shipping.

Old Magnet,
That sounds like something I would be very interested in.
Is it easy to mount? Looking at you check off list what would I have to do?
thanks

It's a little tricky to start the one mounting bolt to install the starter but other than it being heavy and awkward it's a no brainer. Works best if you can hang/support the weight of the starter while installing. The 12A already has the hole in the flywheel housing (remove the three bolt cover plate).

The starters I have are 24V so you will need batteries and wiring, switches, battery box and mounting etc. Also would need matching generator if you choose to install one.

If you insist on 12v I'd have to set one up.

I do have to remove the pony motor right?
I do want to order a starter from you. How soon can you have ready to ship?
What matching generator would I get?
Is the compartment under my tank big enough for a battery boxe?
Do you have any pictures of install, battery box ect.
Thanks

Pony motor can stay if you choose.
If you have a parts book for your 12A, check the attachment section as 24V direct start was a factory option with batteries mounted under tank.
I have the 24v starter on hand, just need to clear payment.
I don't have pictures of battery installation on the 12A.

This is the generator/alternator and adapter package I would recommend. Not something I have for sale. Aftermarket price is about $450 as I recall.

General Gear has a 955 12A in the yard for dismantling. It may have everything you need. John is very good to deal with.

My 955 12A is factory direct electric start if you need pictures of anything or info on it such as wiring, etc.

Yes, you can go back to the original inertia drive starter and system but be aware that parts for that starter, particularly the drive are obsolete and very hard to come by.

I will look at my parts book tonight to see what you mean Old Magnet. Do you have any pictures of installing the direct drive. Is it easier to remove the pony motor or leave it in? Is their instructions on install you can direct me to so I know I am reading/looking at correct one.
thanks

You can view how the starter mounts up on my website.
http://sites.google.com/site/oldmagcat/

40,50,42MT starters all mount the same.

No difference if pony remains or not. In your case you don't need to remove the pony to use the space for batteries.

The starter is located right below the solenoids(there are two solenoids; one reason being so that the starting motor is guaranteed to receive a full 24V) in the space between the engine and the chassis frame. I couldn't get a good picture of the whole unit, but got one of the nose cone bolted to the flywheel housing. You can see the blank space behind the head where the pony engine would be located.

I also show the back of the firewall where the battery disconnect and heat-start-switch is located. You can see that the batteries are located under the fuel tank.
