  • Starter switch on NAA
  • I want to replace the starter switch on my 1953 Golden Jubilee. I believe a lock washer and nut have to be removed from inside the case. How best to proceed? If it means removing the top cover, are there any cautions or tricks involved that I should carefully note.

  • First, it is your tractor so you can do anything you wish to it. That being said, it is also important that you perform true root cause problem solving procedures for any issue/problem. You donít want to be replacing parts until you know if the old part is defective or not. Never assume a part is bad otherwise. So, I have to ask, is the starter push button switch working now? If not, you could have other issues causing the malfunction. Often poor/incorrect wiring is the culprit. Many times, when fellas attempt to do a 12-volt switch over job, wiring gets all mucked up. Even if system is OEM 6V/POS GRN, if not wired correctly, problems will arise. Often times the problem is identified as a bad battery, whether 6V or 12V. If the starter motor just click, click, clicks when the starter push button switch is activated, it isnít the switch, or the starter motor solenoid, it is usually a weak or bad battery. How old is it now? Get it tested for specific gravity at a starter shop or auto parts store. If the starter motor needs to be rebuilt, your local shop can test it and rebuild it. Ditto for the generator. If you have a 12V switchover job, is it done correctly? We have a superb document in our HOW-TOís forum, under sub category ĎELECTRICALí. Search for: ĒWIRING PICTOGRAMS by JMORĒ created by a member here, Jesse Morris, to use as a correct wiring guide and scroll down to find your system. You will also find the 39-53 MPC a useful tool as it lists all the parts for the Nís up to the NAA, including the starter pushbutton. The I&T FO-19 manual is exclusively for the Ford NAA/JUBILEE. It has the starter system in it as well. All Iím saying is to confirm the problem before dropping your cash and time on something that may not be the root cause problem. The starter switch push button is part number 8N-11500. This pushbutton switch was used from 1948 thru 1964 on all models. There is also a gasket that goes with it. JUST8Ns has the parts.

  • The top cover has to be removed in order to change out the switch. at the rear of the cover is a tab that covers a spring and check ball. make sure the spring is not lost inside the trans or elsewhere. Replace cover gasket. not a hard job at all.

  • Once I loosen the bolts and start to lift the top cover, will there be any other issues to deal with, such as unhooking the shift lever (?) or whatever.

    I'm hoping that it will be as simple as lifting it (just) high enough to reach in and loosen the nut, pull out the old starter switch, re-insert the new one and carefully tighten up the nut, put on a new gasket and move on...

    Please advise if you know of any follow-up details besides removing bolts and lifting the cover.
    Many thanks,
