10.10.20 Checking the Piston Ring Gap
-
Insert each of the three piston rings in turn, in a
part of the cylinder that still maintains its
original diameter, making sure they are square
to the axis of the cylinder.
-
Measure the piston ring gap using feeler
gauges.
-
Replace piston rings exhibiting a gap exceeding
the specified limit.
Note:
Before replacing the piston rings alone, on
the original piston, check the piston ring to groove
clearance and the piston to cylinder clearances are
within the specified limits. The new rings may sit
differently that the old ones, which had bedded-in,
when fitted on a used cylinder.
