1. How do I oil the clutch?
Behind the snap ring, next to the sprocket teeth at the end of the clutch. There’s an internal bronze bushing behind the snap ring that requires lubrication and it’s up to you to put it there each time. With the engine off, squirt several drops of oil behind the snap ring while the bushing is warm.
2. How a chain affects your clutch?
When the chain starts falling off the sprocket then it is time to move the engine forward or backward to take up the slack in the stretched chain.
There are four bolts that hold the engine on the motor mount plate. Take an open-end wrench and a socket wrench (most likely a 9/16″) and loosen the four bolts- pull back the engine until you take up the slop in the chain.
Tighten the bolts back again but make sure the two sprockets are perfectly aligned with each other. You don’t want the sprockets out of alignment because this will cause the chain to come off or wear the sprockets unevenly.Leave about a ½” of play between the top of the chain and the bottom—don’t pull the engine back where the chain is a tight as you can get it.
3. How long will the clutch last?
If it’s installed on the engine crankshaft properly, without using the “magic hammer” to pound it on the shaft, using the right length key (1/2″) and observing all the hints that are pointed out in this article, a clutch should last several years.
