Looking for advice on adjusting the pto clutch. I was able to back off the three lock nuts but two of the square head adjusting bolts seem to be rusted in place. They do not move in or out after soaking overnight with pb blaster. Also something odd, my wsm says that the bolts are 6mm. They are not. A 7 mm fits but not tightly. I don't want to use too much force and round off the bolt head. I tried 2 different 6 mm wrenches, they are definitely too small. Has anyone else run into a similar issue like this. Thanks

They may have been loc tited from the factory. You have to use heat?

Also the book references the size of the bolt not the wrench size!

Did you put in a fresh PTO disc?
