Part Nos:
HD-SH/EV-R, Harley Davidson Shovel/Evolution Honing Plate (Torque Plates)
HD-TC-R, Harley Davidson Twin Cam Honing Plate (Torque Plates)

Both Harley Davidson Honing Plate Kits are supplied with a base plate which features side clamping of the spigot area on the Jug to address the recurring problem of spigot deflection during honing. This is especially prevalent in large bore applications and will eliminate additional clearance that would be necessary to achieve correct piston to cylinder wall clearance.

The plate allows the user to hone straight, round bores through the full length of the Jug. The plate also has tapped holes on the bottom side to facilitate clamping into most honing machines.

The HD-SH/ EV-R Shovel/ Evolution Kit is supplied with the above base plate machined with a dual bolt pattern to accept both Shovel Head and Evolution Jugs. There are two Honing Plates, one for Shovel Head and one for Evolution. A hardware kit containing all the fasteners needed to simulate the assembled engine condition for both engine types is also included.

The HD-TC-R Twin Cam Kit is supplied with the above base plate machined with the bolt pattern to accept the Twin Cam Jug and one Honing Plate. A hardware kit containing all the fasteners needed to simulate the assembled engine is also included.
