Hi,

First off, I'm not a life long tractor guy. I'm an ex-city guy who now owns an older tractor. It is an old gas WD45, and it has the push rod starter button. The tractor has been converted to 12 volts.

My problem - I really don't like the push rod starter. Always seems to give me grief, and the replacement parts I've seen are generally of poor quality. I've read various posts about replacing the push rod / button with a solenoid. Seems like something I should be able to do without much difficulty (yes, I know that heavy soldering is required).

My question -- the replacement stud -- is there a direct fit replacement? I've searched and have not found one so far. If there is no direct fit, any recommendations on a size that has worked well for other folks? And where does one find a starter stud? (seems like a stupid question, but I find myself in new territory with repairing an old tractor...learning all sorts of new things like welding patches into rims, and that tractor brakes are "interesting").

Anyhow, thanks in advance for any sage advice that folks can provide.

A good starter rebuilder should have the stud. Replace the starter with one from a AC 100 combine, it has the stud in it. MACK

I keep the stud kits in stock because I'm a rebuilder. I don't normally sell the kits to our customer's because it gets involved tearing down the Starter motor to install the kit. If you have a local rebuilder, he should be able to help you out. They run around $12-$14 bucks for the kit. If you don't have a local rebuilder that can help you out, if you feel you want the challenge, I can sell you a kit and install it yourself...

Thank you both. There is a start/alternator shop about an hour away. I'll start with them.

Figured I should give a final update on this. Your advice and estimate were both spot on. $13 for the post kit, $5 for new bushings, and $20 for labor. Well worth it to let them do the work and test it out.

Look around for a 12 to 18 inch long piece of starter cable. Something with 5/16 ring terminals at each end. You'll need it to connect the solenoid stud to the starter stud. If you can't find one I bet Steve can build one for you.

Trying to do the starter and 12 v conversion. Any suggestions or help.

I offer both services. I can convert your Starter to 12V with a solenoid. I also offer a complete 12V conversion kit for a lot of the early AC Tractors. Visit our website if interested.
