ENGINE BLOCK
CLEANING
Thoroughly clean the oil pan and engine block gasket surfaces.
Use compressed air to clean out:
The galley at the oil filter adaptor hole.
The front and rear oil galley holes.
The feed holes for the crankshaft main bearings.
Once the block has been completely cleaned, apply Loctite PST pipe sealantwith Teflon 592 to the threads of the
front and rear oil galley plugs. Tighten the 1/4 inch NPT plugs to 20 Nꞏm (177in. lbs.) torque. Tighten the 3/8 inch
NPT plugs to 27 Nꞏm (240 in. lbs.) torque.
INSPECTION
1. It is mandatory to use a dial bore gauge to mea-
sure each cylinder bore diameter. To correctly
select the proper size piston, a cylinder bore
gauge, capable of reading in 0.003 mm (.0001 in.)
INCREMENTS is required. If a bore gauge is not
available, do not use an inside micrometer.
2. Measure the inside diameter of the cylinder bore at
three levels below top of bore. Start perpendicular
(across or at 90 degrees) to the axis of the crank-
shaft and then take two additional reading.
3. Measure the cylinder bore diameter crosswise to
the cylinder block near the top of the bore. Repeat
the measurement near the middle of the bore, then
repeat the measurement near the bottom of the
bore.
4. Determine taper by subtracting the smaller diame-
ter from the larger diameter.
5. Rotate measuring device 90° and repeat steps
above.
6. Determine out-of-roundness by comparing the dif-
ference between each measurement.
7. If cylinder bore taper does not exceed 0.025 mm (0.001 inch) and out-of-roundness does not exceed 0.015 mm
(0.0006 inch), the cylinder bore can be honed. If the cylinder bore taper orout- of-round condition exceeds these
maximum limits, the cylinder block must be replaced. A slight amount of taper always exists in the cylinder bore
after the engine has been in use for a period of time.

REMOVAL
1. Remove the vibration damper (1) (Refer to 9 -
ENGINE/ENGINE BLOCK/VIBRATION DAMPER -
REMOVAL).
2. Remove the rear oil seal retainer (Refer to 9 -
ENGINE/ENGINE BLOCK/CRANKSHAFT REAR
OIL SEAL RETAINE - REMOVAL).
3. Remove the oil pan (Refer to 9 - ENGINE/LUBRI-
CATION/OIL PAN - REMOVAL).
4. Remove the oil pump pickup.
5. Remove the windage tray/oil pan gasket.

11. Remove main bearing caps (1) and bearings one
at a time.
12. Remove the thrust washers.
13. Remove the crankshaft out of the block.

INSTALLATION
1. Select the proper main bearings (Refer to 9 -
ENGINE/ENGINE BLOCK/CRANKSHAFT MAIN
BEARINGS - STANDARD PROCEDURE).
2. Install main bearings in block and caps, and lubri-
cate bearings.
3. Position the crankshaft into the cylinder block.
4. Install the thrust washers (1).
