 Topic: D14 starter for a CA?
Posted: 14 hours 24 minutes ago at 10:19pm |
|
Is a 12v D 14 starter mechanically compatible with a CA. I'd like to change it out for the purpose of having a 12v starter and the use of a solenoid. Thanks

i think the 6v and 12v systems use a different flywheel with a different number of teeth.
12v starter has 9 teeth...... 6v starter has 14 teeth....
why not just have your 6v starter changed to a solenoid stud... and use 12v on it ?

For the B,C & CA tractor you MUST use a 14t starter drive. If you are willing to change the starter drive and re-drill the starter mounting hole in the nose cone to properly position the starter drive to the flywheel, it could be made to work. I would just take the CA starter to a competent rebuilder and have it made into a 12 volt unit with a stud instead of a button. You could just use the CA starter as is with 12 volts, however you will probably ruin the ring gear in time.

If it was fun to pull in LOW gear, I could have a John Deere.
Real pullers don't have speed limits.
If you can't make it GO... make it SHINY

As Paul said you might have trouble with the 6V starter using 12V on it then again i HAVE A CA with a 6V starter that I know has been cranked by a 12V battery for at least 40 years.

Is adding a stud to the CA starter pretty straightforward or is it more in-depth that I would need to take it to a starter repair shop?

installing the stud is not for beginners.. but if you have a BIG SOLDER IRON and you are familiar with solder techniques, it can be done at home.

I have gone through various gyrations with Model C starters.
One Model C which I owned 20+ years ago broke 3 starter drives and chewed up the ring gear on the flywheel using 12 Volts; I finally converted it to a 6 Volt alternator system before selling it.
My current Model C is running 12 Volts on the 6 Volt starter, it doesn't slam the drive in as hard as the previous one but it is still quite brisk. This starter is actually from a WD, I swapped the pinion out for the appropriate 14 tooth unit and rotated the nose cone by re-drilling the mounting holes. I also soldered a brass bolt onto the contact to convert it to a solenoid (Ford relay) system. So far so good.
Your mileage may vary

Is there any reason I can't just drill a hole through the original contact and insert a bolt up through the hole? Would there be enough room on the contact to do so? There would be no High heat soldering that way. Just throwing that out there??

the original contact sticks thru a HOLE in the case with the wire solder on the inside and contact on the outside.. If you drill a hole thru the contact, you probably will not have much support left in the remaining piece... and your going to drill into the soldered wire on the inside..

We switched over to 12v on our CA probably 5 or 6 years ago. Original 6v starter works just fine and have not had any issues to this point.

i use the 6v starter on a 12v battery on 4-5 different tractors... I pulled off the PUSH ROD and cut a little triangle plate out of 1/8 inch thick.. i PUSH the button down, then set the triangle plate in the groove and install the pivot pin.. That keeps the switch engaged 100% of the time.. If you cant get it compressed all the way, i install it plate, then push a sheetmetal wedge between the button and plate to compress it the last few thousands..
