The original subject was "Re: Clutch Pilot Tool 7550A".

Hi all, after reading this thread, I want to replace the clutch in my dad's 9N.
Bruce in VA mentioned replacing the Transmission seal and gasket - is that the Oil Seal, Main Drive Gear (8N7052A) and Transmission Case to Center Housing Gasket (9N4662) found on the Ford 9N Parts page?

what about permatex gaskets instead?
This will be my first time splitting the case so any pointers appreciated.

don't mean to hijack this thread, but since the tool is for replacing the clutch, how bout we keep this good info together?

Kubio......while you can now gitt "plastic" clutch centering tool, we recommend removing the tranny input shaft (4-bolts) and use the tranny input shaft to center the clutch. And while the tranny input is apart, replace the oil seal ($3, cheap)

And yes, those are the correct part numbers.
DO NOT USE permatex, NOT NECESSARY.
And yes, yer tranny is supposed to have dangle'n cotter keys.
Remember, clutch disk hub is off-set and thick side faces the tranny.
Polish the pressure plate and flywheel with coarse sandpaper to take the shine OFF.

And NO, you don't need enny wedges, just gently tighten down pressure plate bolts alittle bitt at a time in a "star" pattern. Final inst'l torque is 15ft/lbs. ......Dell

All you need is gasket 7052 (main shaft to tranny) and the seal, 7067. You should also replace p/n 7580, the throwout bearing. You are splitting the center housing from the engine & not from the transmission. As Dell sez, pull the main shaft & use that as the pilot tool. Then, replace the seal & gasket. Do not use just permatex or any other gasket maker. Use the correct paper gasket & your favorite sealer.

Cut the heads off of a couple of bolts & hand screw them into the bell housing to act as guide studs when you put the engine back on. Slide the engine back on the guide studs & look in there to see which way the main shaft needs to turn in order to slide into the clutch disc. Put the pto & tranny in gear & have a helper use a pipe wrench on the pto shaft to slowly turn the main shaft until it slides into the clutch disc.

Having just spent an hour trying to figure out why the throwout bearing wouldn't touch the pressure plate fingers.....one turn on that clutch adjusting eye-bolt will move that throwout bearing a lot further than you think!
