HINT (Use new cylinder block): Use a piston with the same
number mark as the standard bore diameter marked on the
cylinder block.
3. INSPECT CLEARANCE BETWEEN WALL OF RING
GROOVE AND NEW PISTON RING
Using a feeler gauge, measure the clearance between new
piston ring and the wall of the piston ring groove.
Ring groove clearance:
No.1 0.010–0.080 mm (0.0004–0.0031 in.)
No.2 0.030–0.070 mm (0.0012–0.0028 in.)
If the clearance is greater than maximum, replace the piston.
4. INSPECT PISTON RING END GAP
(a) Insert the piston ring into the cylinder bore.
(b) Using a piston, push the piston ring a little beyond the
bottom of the ring travel, 100 mm (3.94 in.) from the top
of the cylinder block.
(c) Using a feeler gauge, measure the ring end gap.
Standard ring end gap:
No.1 0.300–0.540 mm
(0.0118–0.0213 in.)
No.2 0.350–0.620 mm
(0.0138–0.0244 in.)
Oil (Side rail) 0.200–0.570 mm
(0.0079–0.0224 in.)
Maximum ring end gap:
No.1 1.14 mm (0.0449 in.)
No.2 1.22 mm (0.0480 in.)
Oil (Side rail) 1.17 mm (0.0461 in.)
If the end gap is greater than maximum, replace the piston ring.
If the end gap is greater than maximum, even with a new piston
ring, rebore all the six cylinders or replace the cylinder block.
