Installing cylinder assembly
on H 3 L 30:
– Set pistons „1“ and „3“ to approximately
the same height and attach piston ring
clamping tools - 17 -; attach piston ring
clamping strap 622 469 00 to the centre
piston; see Fig. 71.
– With the help of a second person, care-
fully place the cylinder assembly in
position and insert auxiliary pins
621 646 00 into the recesses on pistons
„1“ and „3“; see Fig. 72.
– Lower the cylinder assembly and at the
same time move the auxiliary pins back
and forth until the pistons enter the cy-
linders.
– Take off the piston ring clamping tools
and move the centre piston back and
forth during the lowering movement until
it enters its cylinder.
– The ring clamping strap is pushed into
the cylinder, and can then be pulled out
of the rectangular side opening in the
crankcase with the aid of a strong piece
of wire.
Installing the cylinder assembly on the

same height and attach the piston ring
clamping tools.
