Removing the Cooled Valve-Seat Ring - Fig . 2
Place puller bush (5) through the exhaust passage
onto the valve-seat ring. From the combustion
chamber side, screw hex. bolt (4), together with
washer (2), bearing (3) and puller support (1), into the
puller bush. Pull out the valve-seat ring by tightening
the hex. bolt. Clean receiving bore in the cylinder
head without damaging it.
Before fitting, gauge the receiving bore in the
cylinder head. If the diameter of the receiving bore in
the case of:
- uncooled valve-seat ring is greater than 79,03
mm,
- cooled valve-seat ring is greater than 72,03 mm
and/or at the bottom is greater than 91,03 mm,
an oversize ring must be fitted. Further details can be
obtained from our Deutz Service Departments.
Canting or the formation of burrs must be
avoided!
Hammering-in instead of pulling-in with puller
tool is not permisible!
Fitting the Uncooled Valve-Seat Ring - Fig. 3 -
Lightly oil seat ring on outer periphery and push it
into the cylinder head. Mount threaded spindle (1),
together with hex. nut (6), washers (5), bearing (4)
and bush (3). The seat ring is pulled onto its seat by
tightening the hex. nut (6). Ensure full seating! A
repetition of the pulling-in operation results in a
certain enlargement of the receiving bore in the cylin-
der head, so that an oversize ring may then be
necessary.
