OK - so I was tightening up the clutch/shaft bolt on a 96 670 rotax motor. I couldn't hold it for the 74 foot pounds to get to spec. So - I grabbed an almost all plastic strap wrench and wrapped it around the shaft between the clutch plates and tried to get to 74 ft/lbs.... Well - I noticed quickly, but not quick enough that the plastic strap wrench has 2 steel nuts on it.
So I ended up making a scratch in each clutch about 2 inches long. I sanded it down a little as it was pretty sharp. It is smooth now, but still able to catch it with a fingernail.
Is this going to tear up my belts if I ever get this thing running????
