clutch woes

I'm in the process of putting a new master cylinder and slave cylinder on my truck and I got the slave cylinder off with no issues, minus the part where i had no light. I'm stuck trying to get the master cylinder off, the nuts just wont come out. How have you guys gotta these little things out? I cant maneuver my body good enough to get a good grip and enough pushing force on it, so were probably going to have to cut it off.

Oh and when did Ford switch to metric? Did that include bolts and stuff? I come from the 70's section and it got me used to fractions not whole numbers.



Thanks, parkerparkerm

Beginning in 1980 for some hardware items. Only metric parts used in the 1960/70's were mechanical parts that originated in Europe, installed in Capri/Pinto/Bobcat/Mustang II / 1978/79 Fiesta / 1979 Capri/Mustang.

If standard (hardware) parts in parts catalog pics begin with a letter (example: N620481-S M8 lock nuts on 7A543 clutch master cylinder), they're metric. If with a number, not metric.

I have found that the engine uses mostly SAE fasteners, while the body and frame use metric. A lot of the frame bolts are 18 and 15 mm. I had to buy individual sockets for the 18 mm as it was not included in my socket sets. The switch was started slowly back in the mid 70's.

I would be worried about the firewall. Cutting that MC is doable, but it has a big steel piston in the center, so cut as close to the firewall as you can. Check behind the seam sealer around that reinforcement plate in the engine compartment. Cracks can hide behind there. Also get a good light under the dash and check for cracks starting at the clutch MC bolts. I hope it's just stubborn fasteners, but alas, that was not the case for me. Good luck to you.
