BLOCK 4636933 - Caterpillar

start by: a) remove pistons1. Check to be sure that all coolant has been removed from the cylinder block.2. Put a cover over the crankshaft bearing journals before removing the cylinder liners.
TYPICAL EXAMPLE3. Install tooling (A) and remove the cylinder liners.Install Cylinder Liners
1. Clean the cylinder liners and block.2. Install the liners in the block without the O-ring seals.
TYPICAL EXAMPLE3. Install tooling (A) and two 5/8"-11 NC bolts 4 1/2 in. long. Tighten the bolts evenly to 50 lb.ft.(67.8 N m).4. 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).5. The liner projection 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 average projection of all cylinder liners under one cylinder head must not vary more than .004 in. (0.10 mm). Turning the liner in the bore can make a difference in the liner projection.6. If the liner projection is not .0020 to .0056 in. (0.051 to 0.142 mm), check the thickness of the liner flange (1) and depth of the liner bore in the block. The thickness of the liner flange must be .4048 .0008 in. (10.282 0.020 mm). 7. The depth of liner bore (2) in cylinder block (3) 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 FM055228-03.8. Put a mark on the liner and block so the liner can be installed in the same position from which it was removed.
TYPICAL EXAMPLE9. 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.
TYPICAL EXAMPLE10. Put clean diesel fuel 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
