INSTALLATION.
1.
Carefully install crankshaft (16, Figure 5-9) into engine block, inserting crankshaft end journal into bearing (15).
Coat the bearing race on crankshaft with lubricating oil.
2.
Coat new O-ring seal (14) and angle ring (13) with lubricating oil and install onto crankshaft (16). Install one
belleville washer (12) with dish facing out, and the second belleville washer with dish facing in.
3.
Compress piston rings (9) with a ring compressor. Position piston (5) with ring compressor onto cylinder (6) and
push piston into cylinder.
4.
Remove ring compressor. Adjust position of piston (5) in cylinder (6) so the piston pin bore is fully exposed below
the cylinder liner.
5.
Install assembled piston (5) and cylinder (6) over mounting studs. Engage the top of connecting rod (2) with piston.
6.
Install piston pin (8) in piston (5) and connecting rod (2) bore. Tap into place until the piston pin is centered. Install
new retaining rings (24).
7.
Install flywheel (Para. 5-14).
8.
Assemble piston (5), cylinder (6), and connecting rod (2).
9.
Locate one half of connecting rod bearing (4) into top part of connecting rod (2). Align the lip of the bearing half with
the groove in the connecting rod. Slide the bearing half into the connecting rod while depressing the center of the
bearing half to conform it to the contour of the rod. Seat the bearing half with both ends flush with the flanges of the
rod.
10.
Turn crankshaft to top dead center (TDC) position. Install piston (5), cylinder (6), and connecting rod (2) while
turning crankshaft to bottom dead center (BDC) position.
11.
Install the second half of connecting rod bearing (4) into bottom part of connecting rod (1) in the same manner as
step 8. Apply a coat of lubricating oil to both bearing halves after they are installed.
12.
Mate bottom part of connecting rod (1) to crankshaft journal. Secure connecting rod using two screws (3). Torque
screws to 43 to 46 ft-lbs (58 to 62 Nm).
13.
Install camshaft (Para. 5-12) and flywheel (Para. 5-14).
14.
Install cylinder head (Para. 5-9).
