maincover Preparation.
1. Place the new seal into a bag of oil for a few hours before installing to loosen it up.
2. Completely clean off the seal with some carb cleaner.
3. Check the area where the seal will be placed. Make sure it is very clean.
4. It isn't really needed but I use high-temp silicon sealant on the seal before installing it.
flushfit To install seal, slowly hammer the seal into place, going around the seal in a circling pattern. If you kink the seal while installing it, the seal is ruined. Keep hammering until the seal bottoms out. It should be flush with the case when done.
flyclean Check the flywheel before installing. Mine had a bad groove in it. I used some 240 grit and polished the edge out.
wendge Install the flywheel. Use a Flathead screwdriver on the left side to hold it while you tighten down on your new flywheel bolts. Be careful not to knock the crankshaft in.
Notice: Always use new bolts. They are of the stretch variety and shouldn't be reused. If you place the flywheel close to the crankshaft end and let the bolts draw it onto the crankshaft end you shouldn't run into the problem of pushing the crankshaft into the engine.
flywheel Torque the flywheel bolts.

clutchspring Place clutch spring onto the flywheel. You might have to hold it there, because nothing really holds it on. You may also want to put a dab of grease on the back where it touches the flywheel before installing it. A little grease on the ends of the spring where it hits the pressure plate wouldn't hurt either.
clutchback Install outer clutch pressure plate. It looks like a top hat and should be placed with the top into the spring so the clutch plate surface is showing.
clutch Install the clutch disc with the long end of the spine away from the engine.
plateclean Install inner clutch pressure plate. You should have checked the outer plate for heat spots and cleaned them up, if there were any. Both of my plates had some ruff spots, but they worked out easily with a polish tool.
back Install the outer clutch pressure plate. You need to place the spacers between this plate and the inner plate at this time. I found it's simpler to assemble the whole clutch with the bolts in it first.
threebolts Install bolts. Do the reverse of the process listed on the removal page.
tool Centering the clutch. Before tightening clutch bolts you need a centering tool to line the clutch up. If the clutch isn't lined up correctly the trany will not fit onto the engine. I just eyed it.
finished Torque the clutch bolts.
