replacing points 68 20hp johnson

Im replacing the points in my 68 20hp johnson . I have never attempted this before , is this easily accomplished? There is a piece of oily felt in the package, is this part of installation or just for moisture control in packaging?

Welcome to iboats!

Replacing the point sets is easy. Physically replace one set at a time. Use the second set as a wire guide to show you where the wires go. To adjust the point gap, rotate the crank shaft until the crank shaft key way aligns with the point sets rub block (the part that contacts the point cam). Set the point gap for .020.
Rotate the crank shaft 180 degrees, and again line up the crank key with the rub block for the second point set and set for .020.

The fiber 'wick' is an oiler. Replace the original with the new one supplied. The felt should contact the point cam and lubricates the cam surface.

You need a suitable puller to get the flywheel off. A harmonic balancer puller will work. Be sure to use Grade-8 bolts.

Then when you reinstall the flywheel it is extremely important that the flywheel and crankshaft tapers be clean and dry and you MUST use a torque wrench to tighten the nut to 40-45 ft/lbs. Ignore this advice and you can just junk the motor because of the severe damage that will occur.
