3.4 Damper Setting
You set the damper 32, Fig. I only after you replace a valve spindle or valve seat, or
after one of the seating faces is ground.
⇒ Remove the damper 32.
⇒ Make sure that the bores in the damper are clear.
⇒ Make sure that the exhaust valve is closed.
⇒ Use a feeler gauge to make sure there is no clearance between the valve plate
and valve seat.
⇒ Use a depth gauge 94124 to measure the height H between the top and bot-
tom of the bore in the top housing.
⇒
Make sure that the distance H is 122
±0.5 mm.
Remark:
For example, if the measured distance H is 121 mm, you must install
one shim 33. Each shim has a thickness of 1.0 mm.
⇒ Install the correct quantity of shims 33 to get the correct distance H.
⇒ Instal the damper 32.
