You said you’ve changed the seal numerous times over your time with the tractor. You have a shaft problem in that case. Many of those crank seals last twenty years and more. I’ve changed literally many thousands of seals in my career. Repeated premature failure always has a cause. Find the cause. And it’s not your pullleys.

I've changed the seals several times over the years because the engine was removed to clean the grass build-up on the heads,etc, not because the seals were leaking but because it was already apart.

There is no repeated premature failure just preventive maintenance.


The engine drives a belt that turns the pulleys.
If the pulleys offer resistance to the point of seizing and stopping the engine, will the engine run hotter or cooler?
If the answer is it will run hotter the next question is, is it possible it got hot enough to cause seal damage?
