Tighten bolts (1) evenly in four steps: 1st step ... 10 lb. ft.(14 N m)2nd step ... 25 lb. ft.(35 N m)3rd step ... 50 lb. ft.(70 N m)4th step ... 70 lb. ft.(95 N m)2. Install tooling as shown. Tighten bolts (4) evenly in four steps: 1st step ... 5 lb. ft.(7 N m)2nd step ... 15 lb. ft.(20 N m)3rd step ... 25 lb. ft.(35 N m)4th step ... 50 lb. ft.(70 N m)3. Measure cylinder liner projection with dial indicator (3) in 1P2402 Block (2) as shown. Measure at four places around each cylinder liner near the clamped area. Average of four projection measurements from any cylinder liner must be ... .005 .003 in.(0.13 0.08 mm)Maximum permissible difference between all four measurements ... .002 in.(0.05 mm)Maximum permissible difference between average projection of any two cylinder liners next to each other in the same spacer plate ... .002 in.(0.05 mm)4. Minimum permissible depth to machine counterbore to adjust cylinder liner projection ... .030 in.(0.76 mm) Maximum permissible depth to machine counterbore to adjust cylinder liner projection ... .045 in.(1.14 mm)Install a .030 in. (0.76 mm) shim plus any added shims necessary to get the correct cylinder liner projection. Be sure that the .030 in. (0.76 mm) shim is directly under the cylinder liner flange.Put 7M7260 Liquid Gasket on the top of the top shim and on the bottom of the bottom shim before installing.(5) 3H465 Plate.(6) 8B7548 Push-puller Crossbar.(7) 1P2397 Adapter plate.(8) 3H465 Plate (installed upside down).(Without Spacer Plate)
