  • Starter removal
  • I was given a '42 9N a few years back and I am slowly getting to know the thing. I'm trying to remove the starter but directly in front of the brush end plate, there is a pit-cock of some sort. I don't know what it is for and I can't figure out how to get the starter frame past it. Has anyone run into this situation and how did you resolve it?

  • I think you mean the petcock drain for the coolant. Yeas, it is much easier to remove the starter when the petcock is removed first. The N starter pocket has a scalloped section machined out at the 2 O'Clock Position for easier starter assembly and removal. Follow Bruce(VA)'s tips on R&R 'g it and look in our HOW-TO's forum for more help. Best to get the essential manuals too if'N yer gonna be a an N-Owner. We have the 1942 Master Parts Catalog in our MANUALS forum for free download as well, but, realize, many of these N's have been changed over the years and some parts are no longer serviced. Many have been switched from the original 6V/POS GND to 12 volt systems so look at that first. Get the I&T F-04 manual and the 39-53 MPC first after the '42 MPC.

  • Re: Starter removal
  • Thanks, Tim, for the pics. I do have the I&T FO-4 manual but that does not show me the starter pocket. . . in color. My tractor was changed over to 12 volt by the previous owner. Unfortunately, by the time I received Bruce's response, I had the brush plate and springs already off so I do have a mess (I do have a solution for that though).

    I'm curious though. How would I go about removing the petcock? It looks to me to be part of the block.

  • The block coolant drain petcock is on the LH side of engine, near the starter as shown in the picture. It is brass and is screwed into the block via an NPT (tapered pipe threads) petcock. Removing the starter is easier when this is also removed first. Drain some coolant out of the block first. Go the bottom of the radiator and you'll find another brass petcock similar to this one and place a pan/bucket underneath then open it up to drain coolant.

  • Re: Starter removal
  • Tim, thanks for the help. The picture of the opening made me think that I would have to lift the starter up and to the right to free it. Sure enough, once I put pressure in the right direction, the starter almost came out on its own. The petcock was never an issue.

    I like it when things break because then I learn something. (Right!)

  • The starter has 3 major exterior components; front plate, barrel & rear plate. The 2 bolts that hold the starter on to the bell housing go through all three components & hold it all together. To remove the starter, unscrew the bolts out of the block & put a nut on one of them. Otherwise, the starter comes apart. Not fatal, but not fun either. (tip # 36 at the link
    below) Then, loosen the two bolts holding the oil filter canister to the block, (it does not need to be removed) remove the dipstick, and keep the starter close to the block while pushing the front of it down and lifting the back up. Sometimes you have to remove the drain petcock as well.The bendix is behind the flywheel; your job is to get it over the flywheel.

    Caution: while the starter is off, resist the temptation to screw with the bendix. If you extend the bendix, and it is not the OEM bendix w/ the big spring, you will have a hard time getting the starter installed.

    To install the starter, keep it close to the block while pulling the front of it up and pushing the bendix back into the hole. The bendix has to go behind the flywheel; your job is to get it over the flywheel.
    Lastly, while the starter is off, polish the block & all starter mating surfaces w/ sandpaper to insure a good electrical ground. First, clean the mating area between the barrel and rear plate. Then, clean the mating surfaces where the aluminum rear plate meets the bell housing. The starter's ground circuit is not only through the two long bolts but from the barrel to the rear plate & then to the bell housing as well.

  • Re: Starter removal
  • Thanks, Bruce for the very informative response. Read my response to Tim. I was able to remove the starter and the the petcock was not the problem. I appreciate your willingness to help (and Jim).

  • The petcock just screws in to place (pipe thread) just put a wrench on it and turn it out. You may have enough buildup behind it that no coolant will come out.
