Application:

The VDS1A is designed to reface valve seats of the engines of motorcycles. cars and light commericial vehicles.

Features:
The VDS1A 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 VDS1a 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 VDS1A below the crank handle. The steady rest eliminates runout when rotating the VDS1A 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 VDS1A is quite simple.
Place VDS1A 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 VDS1A by hand around the pilot to reface the valve seat.
