I'm trying to remove my 86 lt250R quadracer clutch basket and I'm running into some trouble. The manual calls for some "grabbit" tool. What are my options here? The screwdriver/oil filter wrench method didn't work, that sucker is really stuck on there. I'll probably have to get out the breaker bar!

 

The only way to do it is with an impact wrench.

 

Got it, I didn't really understand that an impact wrench "hammered" the nut at the same time it twisted it. I have got it successfully off.
Is the impact driver the best way to put the nut back on, too?

 

I recently had the joy of taking a clutch basket off, and ended up shearing a keyway off the other side of the motor due to it being so tight. My 1/2 torque wrench tops out at 125ft:lbs and it would click and not even budge the nut. The impact spun it right off. I put it back on with the impact because I assumed since it was on so tight it wouldn't hurt anything. I just didn't hammer it too hard.

 

Yep Impact is the only way to go.
