1. Use a Grade 8 bolt. It MUST have NO threads where the shaft of the bolt is in contac with the square 1 inch drive shaft. This is the difference between Slide Shaft bolts and regular bolts, the smooth shaft is LONGER and the threaded end is short.
2. When you continue to shear the bolts, the problem is the Square 1 inch drive shaft. Instead of a 1/4 inch diameter hole that the bolt goes thru, the hole has become elongated. This causes a SHEAR action when engaging the motor and drive shaft. That small extra room on the hole causes the square driveshaft to move slightly and this causes a Shear action on the bolt. You either remove the 1 inch square drive shaft and cut 1 inch off the end and drill a new 1/4 inch hole or you cut it inside the storage area and drill a new 1/4 inch hole. Doug
