Application:

The VDS2 is designed to reface valve seats of the engines of trucks. heavy construction vehicles and small ships.

Features:

The VDS2 refaces the valve seat in a lathe-type facing action.
A gear head includes a feed mechanism for continous outward transverse motion of the single point turning tool when the VDS2 is rotated around a pilot inserted in the valve guide.
The direction of the feed motion is defined by an exchangeable adapter head screwed to the gear head.
A steady rest which is mounted on the cylinder head stabilizes the VDS2 below the crank handle. The steady rest eliminates runout when rotating the VDS2 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 VDS2 is quite simple.
Place VDS2 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 VDS2 by hand around the pilot to reface the valve seat.
