Ok, I've been reluctant to post this for fear of sounding like a dumb-a**, but here goes. I've done clutches & trannys on later models, but this is my first go-round with the flathead & closed driveline. Is it normal to have clearance problems r&r-ing the trans? There doesn't seem to be enough room to pull the trans back far enough to get the input clear of the disc. Trans case hits support cross member & mount ears on rear bearing retainer won't clear frame & floor pan. I did finally get it out somehow with a lot of pulling, wiggling, & bad words! So, now its time to go back in-----What's the trick? Remove the rear brng. retainer? Guys have been doing this in driveways & backyards for 70 years! What am I doing wrong?
Thanks, Bob ( 40 four door Deluxe)
 
Sounds like you might not have the rear of the engine up high enough, and have the rear mounts out of the way....
 
I don,t know if you are trying to get it out the bottom,but the trans comes out to top.Raise engine should not be a problem.
 
Thanks Guys, But engine is jacked up & touching firewall, mounts are out & yes I'm working from the inside. It has headers & dual exhaust I didn't unhook. Could that be keeping the back of the engine from going high enough?
 
I found the easiest way to replace a clutch on a 40 ford was to remove grill radiator and pull engine trans out of the car together....ive done it your way but cracked one of the top bolts on the bell housing...with the grill out i found i didnt have to nose dive the motor to the transmission if it was still in the car....my exhaust is always disconnected when i pull an engine....just so much easier to inspect everything out of the car when you pull of the pressure plate and disc and inspect the flywheel...i can see things alot better in daylight...the flywheel may need to be surfaced and your pilot bushing may be oblong,,,I also found out that some tractor companies carry the correct pressure plate!! good luck Gump
 
Be careful using a tractor pressure plate! They bolt right up but if an actual tractor part it will not have the counterweighted releae fingers. V8 plates use counterweights that apply extra pressure to the disc as the RPM's come up to prevent slippage and yet provide an easy to push pedal. Hold your clutch pedal nearly all the way down and rev the engine to 3,000+ RPM. You will feel the pedal push back as the RPM goes up. Tractor engines (9N, 2N, 8N) only run about 1900 RPM so no weights used.
