Timing gear?

My 9N, front mount, turns over good but the gear that the distributor tang mounts into, doesn't turn. How really bad is this? Can I pull hood and then move front wheels out and then pull the timing cover off without tearing down the whole engine, and just replace the timing gear? If so, how do I replace gear and make sure I do it so that I am in time? And, if I have sheared a tooth or teeth off of the timing gear, where would these wind up, in the pan maybe getting ready to cause me bigger problems?

Chuck,
You don't have to separate the front wheels to pull the timing cover. After you remove the hood, radiator, fan, and distributor, You will have to loosen the bolt in the crankshaft pully and pull the pully forward about 1/2 to 3/4 inch. (the timing cover sets on position pins (two, I think) so after removing the bolts, you have to pull the cover forward off the pins.) Loosening the crank bolt may be a challenge. The whole engine wants to turn over when you try to loosen it. I read on this board someone suggested removing a spark plug and inserting some nylon rope -- enough so that the piston will not be able to reach top dead center, which will allow you to loosen the bolt.

Sorry to hear about your perdicament. Hope you can get it towed somewhere more agreeable for the repair work.

Good Luck,
Steve

Steve, Thanks for the input. When you were talking about the crank bolt, are you referring to a bolt on the pulley? or will I have to pull the crankshaft gear off? Looking in the ford FO4 manual, it looks like the timing gear is on the end of the cam shaft and they indicate that on early 9N, may be very difficult to remove from cam shaft. Any experience here? Thanks for any additional help. Chuck

Chuck,
The big bolt (15/16ths) in the end of the crank pulley is the one I'm talking about. You don't have to remove the crankshaft gear.

I'm reading in the FO-4 where it says to disconnect the drag link and radius rod on one side and swing the front end assembly out of the way. Maybe that's easier, I don't know. Never tried it that way. But I didn't disconnect any of the front end. I think you have to do that little maneuver to REMOVE the pulley. I chose not to remove it, just slide it back a little. That way you can pull the timing cover forward off the position pins then lift it straight up. I've done it a couple of times that way. Good luck.

Steve

Steve, Thanks, that makes sense. I towed my tractor out of the field last night with my wife's help. She drove the Suburban, thank goodness for four wheel drive, and pulled me back to the house. Now at least I can work on a flat concrete surface with necessary tools at easier reach, oh yeah, and with light, as I will probably have to do most of this in the evening after work. Thanks again. I will post later as I get into it. Chuck

if you shered off a tooth it will be in the oil pan wiating to couse you greef . get your self an fo4 manual it with help you with this job not to hard ,dont think you will have to take off the front wheels but again the fo4 will help you with that . there are timeing marks on the cam gear and the main gear that have to be lined up when you take it apart so you stay in time when you put it back together. good luck

Thanks. That is better news than I expected. Wish I wasn't stuck in the field on the other side of my property. Thanks again, Chuck
