Remove Cylinder Liners
start by:a) remove pistons1. Put a piece of gasket material or a cover over crankshaft journals as a protection before liner is removed. 2. Put tooling (A) in the cylinder liner.
Do not cause damage to piston cooling tube (1) when tooling (A) is installed.
3. Use tooling (A) to remove the liner from its seat in cylinder block. 4. Remove cylinder liner (2) from its bore in cylinder block.5. Remove filler band (3) and seals (4) from the liner.Install Cylinder Liners
1. Clean the cylinder liners and block. Install the liners in the block without the O-ring seals. 2. Install tooling (A) on the liner. Tighten the nuts that hold tooling (A) evenly to a torque of 50 lb. ft. (70 N.m).3. Check the liner projection with tool group (B) at four locations around the liner. The difference between the four measurements must not be more than .002 in. (0.05 mm). The liner projection must be .004 to .008 in. (0.10 to 0.20 mm). The measurement between liners next to each other, must not be more than .002 in. (0.05 mm) difference. The liner projection can change if the liner is turned in the bore.4. Put a mark on the liner and block so the liner can be installed in the same position from which it was removed. 5. Install new seals (2) on the cylinder liners. Put liquid soap on the seals and in the bores in the cylinder block. 6. Put SAE 30 oil on filler band (1) and install it on the liner. Install the liner immediately in the cylinder block with tooling (C).end by:a) install pistons
