START BY:a) remove pistons1. Check to be sure that all coolant has been removed from the cylinder block.2. Cover the crankshaft bearing journals before the cylinder liners are removed.
Typical Example3. Remove the cylinder liner with tooling (A).Install Cylinder Liners
1. Clean the cylinder liners and block.2. Install the liners in the block without the O-ring seals. 3. Install tooling (A) and two 5/8"-11 NC bolts 4 1/2 in. long. Tighten the bolts evenly in four steps: 5 lb.ft. (7 N m), 15 lb.ft. (20 N m), 25 lb.ft. (35 N m) and 50 lb.ft. (70 N m).4. Check the liner (projection) height 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).5. The liner (projection) height must be .0020 to .0056 in. (0.051 to 0.142 mm). The measurement between liners next to each other, must not be more than .002 in. (0.05 mm) difference. The maximum permissible difference between the average projection of all cylinder liners and the projection of any one of the liners is .004 in. (0.10 mm). If the liner is turned in the bore, it can make a difference in the liner (projection) height. 6. If the liner (projection) height is not .0020 to .0056 in. (0.051 to .0142 mm), check the thickness of the liner flange (1) and depth of the liner bore (2) in the block (3). The thickness of the liner flange must be .4048 .0008 in. (10.282 0.020 mm). The depth of the liner bore in block must be .401 .001 in. (10.19 0.03 mm). If the liner bore in the block is worn and the measurement is not correct, the liner bore can be corrected with a cylinder block counterboring tool. See SPECIAL INSTRUCTIONS, FORM FM055228.7. Put a mark on the liner and block so the liner can be installed in the same position from which it was removed. 8. Install new seals (4) on the cylinder liners. Put liquid soap on the seals and in the bores in the cylinder block.
The liners must be installed in the cylinder block immediately after band (5) is installed. Make sure the marks on the liners and the cylinder block are in alignment when the cylinder liners are installed.
9. Put clean engine oil on band (5) and install it on the liner as shown. Put clean SAE 30 oil on the liner and install it immediately in the cylinder block with tool group (C).END BY:a) install pistons
