Tightening bolt on electric PTO for Sabre 1948HV

I recently had the bolt that holds the electric PTO/drive pulley to the main shaft of the engine break and had to replace it. I'm now having problems getting it tight enough to not work itself loose while mowing.

Does anyone have any suggestions on how I can stop the crankshaft from turning while I try to tighten the bolt?

thanks for any suggestions!

Use an impact wrench.
I'd also use some blue Loc Tite.
You did replace it with a grade 8 bolt right?

Ah, impact wrench, good idea!

I bought a OEM replacement bolt, so I'd assume it's the same grade as the one that broke....It had six little tick marks on the head.

Thanks for the help,
mike

Welcome to the forum.

I was going to suggest a star washer but I see your problem is holding the crank from turning.

Yep, use an impact gun and make sure your lock washer is in place.
