M 06.00 Cylinder

- 21 - 29 -
Preparations:
Ref.: M-Disassembly cross reference
scheme.
Dismantling:
– Remove (pull) cylinder carefully from pis-
ton.
Inspection / repair:
– Check cylinder for broken cooling fins,
wear, score marks or any other damage.
Index of piston ring wear
To be measured at the very bottom end of
the cylinder where normally no wear at all
occurs during operation.
– Insert respective piston ring which
should be checked into the cylinder.
Take care for right-angled position !
– Measure dimension a with feeler gauge
and compare with figures as indicated in
Tab. A.
These data refer to oversize as well.
Piston rings exceeding figures as indi-
cated have to be replaced!

Index of cylinder wear

To be measured at the upper end of con-
tact area of piston rings i.e. in the area
where usually the highest amount of wear
occures.
– Insert new piston ring.
Take care for right-angled position !
– Measure dimension b with feeler gauge
and compare with figures as indicated in
Tab. A.
These data refer to oversize as well.
If the max. figure is exceeded the cylin-
der is worn out and has to be replaced
or used for re-conditioning to oversize as
indicated in Tab. B.

Assembly:
– Offset the piston ring gaps by approxi-
mately 120° to each other to avoid ex-
cessive blow-by.
Piston rings and cylinder have to be
properly oiled !
– Set the scale of the piston ring clamping
device - 21 - dependant upon diameter
of piston.
– Carefully slide the collar over the piston
rings and clamp the tightener.
– Carefully fit the cylinder !
As soon as the cylinder has been slid
over the piston rings, release the tighten-
ing strap and remove the clamping
device.
Honing
General:
If an already run-in but not worn cylinder is
dismantled and re-used the cylinder has to
be re-honed.
The same procedure is applicable for en-
gines, which due to low load have not bro-
ken-in and therefore show excessive oil
consumption due to cylinder glazing.
In this case the glazed smooth cylinder
wall must also be honed.
After re-honing measure piston ring gaps
again. The honing process as such needs
certain experience and should be carried
out by a HATZ-Distributor or any other au-
thorized workshop.
For honing use tool - 29 -
