Fitting piston rings
Fig. 5
Use the piston ring pliers to engage the piston
rings in the relevant piston ring groove (TOP facing
upwards).
Checking piston ring axial clearance
Fig. 6
Determine the piston ring clearance in each piston
ring groove at various points using a feeler gauge.
To do so, press the piston ring fully into the piston
ring groove at the point to be measured.
Replace the piston and piston rings if the clea-
rance determined is too large.
Piston ring axial clearance, see “Service Data”.
