This all steel crank bolt kit is used to solve the crank snout damage.
Use of this kit solves the crank hub from galling to the crankshaft snout on engines with dampeners or blower drives.
This Belleville washer design is made from chrome vanadium spring steel.
The 3/4-16 bolt is a grade L-9 hex head that is torqued up to 400 foot pounds.
The use of a flange head bolt does not allow the bolt to have proper torque stretch. The flange works like a frictional clutch, robbing some of the torque of the torque wrench from properly tightening and stretching the bolt.
This bolt and washer properly clamps the crank hub to the crank snout, eliminating the back and forth movement that galls the hub and snout together. This galling action makes it nearly impossible to remove the crank hub from the crank.
For use on standard 426 crank snouts, and spline snouts.
For spline snouts and outboard bearing supports, please call 530-308-8827 for needed information so you get the correct length crank bolt kit the first time.
The standard 426 kit comes with a standard 2″ long L-9 bolt and detailed instructions.
Longer bolts up to 6″ are available, and special length bolts are made as ordered, at additional cost.
