General
Valve seats of which the seat surfaces are badly damaged, or on which the wear limit
has been reached through frequent grinding, must be replaced.
The most advantageous position for replacing the valve seat is to bring the valve cage in
a vertical position as shown in Fig. 1.
Note: When the valve seat must be removed with the valve cage in the inverted
position, it must be suspended on the engine room crane slightly above a
wooden underlay. Device 94261 can then be attached from below and the
valve seat carefully withdrawn until it drops caused by its own weight .
Therefore, the valve seat must be properly secured with additional wooden
underlays. The distance to the wooden underlay is to be kept as small as
possible to avoid any accidents or damage.

Removal
1) Fit both pairs of ring halves of the valve seat fitting and dismantling device 94261
into the groove on the circumference of the valve cage 2 and valve seat 1
respectively.
2) With the aid of the three jack screws of the valve seat fitting and dismantling device,
the valve seat can be pressed out of its seating in the valve cage.
D
Should a valve seat be removed for any reason, it must be reground by means of
valve grinding device 94291 before refitting.
