start by: a) remove pistons1. Remove coolant from cylinder block.2. Put covers on journals of crankshaft for protection from dirt or water. 3. Use tooling (A) to remove the cylinder liners.Install Cylinder Liners
1. Clean the cylinder liners and the liner bores in the cylinder block.2. Install the cylinder liners in the block without the O-ring seals.3. Check the cylinder liner projection as follows: a) Install the 3/4"-16 NF bolts and the 2F126 washers of tooling (B) on the cylinder block next to each liner. Tighten the bolts to a torque of 70 lb.ft. (9.7 mkg) to hold the spacer plate in position on the block.b) Put the adapter plate and one plate of tooling (B) on top of the liner and install the remainder of tooling (B). Be sure the bar is in position at the center of the liner. Tighten the bolts that hold tooling (B) evenly to a torque of 50 lb.ft. (6.9 mkg).c) Check to be sure the distance from the bottom edge of the bar to the top of the cylinder block is the same on both sides of the liner. d) Check the cylinder liner projection with tool group (C) at four locations around the liner.e) Liner projection must be .005 .003 in. (0.13 0.08 mm). Measurements on the same liner must not be different by more than .001 in. (0.03 mm). Average measurements between liners next to each other must not be different by more than .001 in. (0.03 mm). Turning the liner in the bore can make a difference in the liner projection. 4. If the liner projection is not .005 .003 in. (0.13 0.08 mm), check the thickness of the following parts: spacer plate, spacer plate gasket, and cylinder liner flange (1). The thickness of the spacer plate must be .338 .001 in. (8.59 0.03 mm). The thickness of the spacer plate gasket must be .008 .001 in. (0.20 0.03 mm). The thickness of the cylinder liner flange must be .3500 .0008 in. (8.890 0.020 mm). The cylinder liner projection can be changed by making a counterbore in the block to a minimum depth of .030 in. (0.76 mm) with a cylinder block counterboring tool. See SPECIAL INSTRUCTION, FORM FM055228-01. Shims are available for the adjustment of the liner projection. See PROJECTION OF CYLINDER LINER in 3406 VEHICLE ENGINE, TESTING AND ADJUSTING for the shim thickness and part number.5. Put a mark on the liner and block so the liner can be installed in the same position as it was removed.6. Remove tooling (B) and (C). Remove the liner. Install new O-ring seals on the liners. Put 7M7260 Liquid Gasket Material on the under side of the cylinder liner flange. Do not put 7M7260 Liquid Gasket Material on the cylinder block. 7. Put liquid soap on the O-ring seals and on the cylinder bores. Put the cylinder liners in position in the cylinder block bores. Push the liners down with
