Features:
The VD2 refaces the valve seat in a lathe-type facing action.
The tool head includes two inclined slideways for refacing 30° and 45° valve seats.
A single point turning tool is clamped to tool slide guided in the respective slideway.
When the VD2 is rotated around the pilot by hand, the turning tool travels in a circle around the valve seat with continuous outward transverse feed motion under the correct seat angle.
A steady rest which is mounted on the cylinder head stabilizes the VD2 below the crank handle. The steady rest eliminates runout when rotating the VD2 around the pilot. As a result, the seat is refaced to concentricity with the valve guide under the correct seat angle.
Operation:
Operation of the VD2 is quite simple.
Place VD2 on pilot inserted in valve guide.
Mount steady rest for additional support.
Place turning tool in front of the inner edge of the valve seat.
Set depth of cut by turning a micrometer mechanism to maintain positive control over the material to be removed from the valve seat.
Rotate VD2 by hand around the pilot to reface the valve seat.
Application:
The VD2 is designed to reface valve seats of the engines of trucks. heavy construction vehicles and small ships.
