A = Measuring surface on cylinder liner
B = Measuring surface on cylinder block
C = Tip of dial gauge
D = Cylinder liner height D = A-B
Measuring cylinder liner height
1. Thoroughly clean the cylinder block liner
shelf, the face around the cylinder, the
cylinder liner shelf and the upper face of
the cylinder liner.
2. Fit the cylinder liner without O-rings and
twist down by hand into position.
3. Lift out the liner and wipe the liner shelf in
the cylinder block and the cylinder liner
shelf.
4. Insert the cylinder liner without O-rings
and twist it down into position again by
hand.
5. Place straight edge 87 198 with dial gauge
98 075 on the liner and zero the dial gauge
to the liner (A). Slide the tip of the dial
gauge over to the cylinder block (B) and
measure the height of the liner (A-B) as
illustrated.
6. Measure each liner at two diametrically
opposite points transversely across the
engine.
- The cylinder liner must be slightly above
the face of the cylinder block.
- The difference between the two
measurements on the same liner must not
exceed 0.02 mm.
- The height of the cylinder liner D (=A-B)
above the block should be 0.20 – 0.30 mm.

C Measure the diameter of the cylinder wear ridge 2-8 mm down
the cylinder bore.
D Measure the diameter of the cylinder bore 10-12 mm down the
cylinder bore.
2. Cylinder liner type A
The difference between the diameter of cylinder wear ridge C and
the diameter of cylinder bore D must not exceed 0.06 mm
Cylinder liner type B
The difference between the diameter of cylinder wear ridge C and
the diameter of cylinder bore D must not exceed 0.06 mm
