(4) 7K-1977 Washer Note: The 7K-1977 Washer (4) is made of a cotton fabric that is impregnated with resin. The washer will not damage the sealing surface of the cylinder block.
Secure the spacer plate to the cylinder block with bolts (1) and gaskets (2), (3) and (4). Use two bolts on each side of each cylinder. Use three gaskets for each bolt. Tighten the bolts evenly in four steps:
Tighten the bolts to a torque of 14 N m (10 lb ft).
Tighten the bolts to a torque of 35 N m (25 lb ft).
Tighten the bolts to a torque of 70 N m (50 lb ft).
Tighten the bolts to a torque of 95 N m (70 lb ft). Note: Use the bare cylinder liners. Do not install the filler bands or the O-ring seals onto the cylinder liners yet.
Make sure that the surfaces of the engine block, the cylinder liner, and the spacer plate are clean. Remove any nicks from the surface of the spacer plate.
Place a cylinder liner into a bore. Fit adapter (6) onto the cylinder liner. Place plate (7) onto the adapter.

Use crossblock (8), two plates (7), and two bolts (9) to seat the cylinder liner in the bore. Tighten the bolts evenly in four steps:
Tighten the bolts to a torque of 7 N m (5 lb ft).
Tighten the bolts to a torque of 20 N m (15 lb ft).
Tighten the bolts to a torque of 35 N m (25 lb ft).
Tighten the bolts to a torque of 70 N m (50 lb ft). After the bolts are tightened, Measure the distance from the bottom edge of the crossbar to the surface of the spacer plate. The distance must be equal on both sides of the cylinder liner. If the distance is not equal, repeat the bolt tightening.
Use the 8T-0455 Liner Projection Tool Group (10) to measure the cylinder liner projection. Note: The Special Instruction, SMHS7727 is provided with the tool group.
