  • Ford 9N timing issues
  • I'm helping a friend get a Ford 9N running. He sent it to a mechanic who replaced or cleaned pretty much everything in the motor. Unfortunately he went bankrupt without getting the tractor running. At least he got it put back together and returned it on a trailer. The tractor will turn over (but not very fast). Spark is happening in the correct time and we performed all the steps in the manual to make sure the timing is correct. Since we couldn't get it to fire, (not even a pop) we decided to pull start it. We noticed that oil is being blown out the air filter so we pulled the intake to the carburetor off and turned it over. It seemed to blow air out not pull air in. We're wondering if the timing gear is not installed correctly. What steps should we perform to make sure this is the issue or is there something we're missing? Thank you.

  • All great thoughts! Unfortunately we won't be able to work on it for a few weeks but We'll keep you posted on what we find out. Thank you.

  • If engine checks out OK, problem most likely in incorrect wiring. Are you set up with the OEM 6V/POS GRN system or has it been switched out to 12V?

  • The tractor had an 8V battery and we thought it might be weak so we switched it back to a 6V. After reading some other posts, it looks like we'll have to also do something with the regulator. We should be able to get it running before looking at that, correct?

    With the intake manifold off, check the position of each valve when it should be at top dead center of the compression stroke. Also that all the valves open and close completely. This should give you an idea about what is happening.

  • Oil/air blowing out. . .
    Cam timing might very well be an issue. Then again maybe not. Engine cranking slow could be the 6V starter and/or a bad ground. I just redid my 8N 6V starter cable with a new 00 gauge wire. Yours? Find #1 on the dist cap, pull the plug and crank it over.
    With thumb over hole, as it builds compression, the rotor should be spinning around to #1 position. is it? Once your on the comp stroke, you can also rotate the engine by hand to get the engine to TDC on the timing indicator and the piston at TDC. Then once again see where the rotor is pointing.
    As long as you have a dirty thumb now, place it over all plug holes and crank. Compression should force your thumb off all holes. Does it?
    Others should be along shortly with vast more knowledge.

  • This 9N has the timing indicator on the front of the engine. Should we be looking at taking the front end off as the manual suggests? We're backyard mechanics at best. ;-) Is there an easy way of telling if we're in the intake or the exhaust stroke? Thanks.
