  • 9n Camshaft Gear
  • I have a 1939 9N with a stripped camshaft gear that obviously needs to be changed. It is the old style gear where the outer portion of the gear is made of fiber and the center is steel with a large slot in it. Is there a way to change this gear without removing the camshaft from the engine? I have the front timing gear cover off but would sure like to avoid tearing the camshaft out if possible.

  • You do realize that big slot in the dear is for driving the distributor, right? So getting it right is the whole deal in a nutshell.... just sayin'....

  • The recommendations I have seen on the fiber gear is to change the camshaft and gear to the newer style with bolt on gear. It might be possible to take that old fiber gear off but getting it back on in perfect time, might be a bit tough. If you go to the newer gear, you should be able to line up the timing fairly easily. I have not done this so don't know all the ins and outs to doing it.

  • Thanks for the input Mike. It looks like I will be pushing the $200 mark for the replacement cam and bolt on gear unless someone has a suggestion on where a better price can be found. I'm thinking about pulling the cam and taking it to a machine shop to have a new fiber gear pressed on. There are alignment marks on the hub to indicate where to press the new gear on. The question is whether or not it is worth the $130 or so this route will save.
