1973 R75/5 Rebuild: New Oil Pan Gasket and Camshaft Seal

Both of these showed signs of leaking oil and I replaced them.  You can read about how I did this here:

When replacing the oil pan gasket, I also cleaned the oil pickup screen and checked to be sure the bolts holding the pickup are tightened to the proper torque, 72 INCH/Pounds, not FOOT/Pounds.  I used an INCH/Pound torque wrench on them and also on the oil pan bolts which were set to 70 INCH/Pounds in several stages.  These bolts are easy to strip out unless you use an INCH/Pound torque wrench.

I put in new points and a condenser when I replaced the cam shaft seal and replaced the timing plate machine screws with two Allan head cap screws, M4x0.7×10. Now its easy to adjust the timing plate points cam with the centrifugal advance weights installed with a small Allan head wrench. And, I won’t be wallowing out the slot on machine screws as happened in the past.

I used my larger adjustable seal puller to remove the camshaft seal, but it makes me nervous since the camshaft seal is small and I don’t want to score the camshaft. After I got the camshaft seal pulled, I looked for a puller for small seals. I found a very promising one, Lisle 58430 shaft seal puller. It’s available at some auto parts stores, but I ordered mine from Amazon.

I think this will work very well on future seal pulling jobs.
