4. INSPECT CYLINDER BORE DIAMETER
Using a cylinder gauge, measure the cylinder bore
diameter at positions A, B and C in the thrust and axial
directions.
Standard diameter:
87.500 – 87.512 mm (3.4449 – 3.4453 in.)
Maximum diameter:
87.52 mm (3.4457 in.)
If the diameter is greater than maximum, replace the
cylinder block.
5. REMOVE CYLINDER RIDGE
If the wear is less than 0.2 mm (0.008 in.), using a
ridge reamer, grind the top of the cylinder.
6. INSPECT MAIN BEARING CAP BOLTS
(for 12 Pointed Head Bolts)
Using a vernier caliper, measure the tension portion
diameter of the main bearing cap bolt.
Standard diameter:
7.500 – 7.600 mm (0.2953 – 0.2992 in.)
Minimum diameter:
7.20 mm (0.2835 In.)
If the diameter is less than minimum, replace the bolt.
