NOTE
The oil cup pocket feeding lubricant to the wrist pin bushing is on the top
of the connecting rod and should be in the up position.
18. Install crankshaft in the power frame. Take care not to
scratch bearing surfaces of the crankshaft.
19. Reinstall the shims (9), gaskets (10) and bearing housings
(8) per instructions in section 10.4.2. When tightening the
fasteners retaining the bearing cover, use crisscross
pattern for tightening with a torque wrench.
20. Reinstall or replace the rod bearings (4) in the connecting
rod and connecting rod caps per instructions in section
10.4.2. Ensure that rod caps are properly assembled with
their mating connecting rod.
21. A dial indicator must be used to properly adjust the endplay
of the crankshaft. Improper adjustment may result in
excessive temperature, vibration, noise, and reduced
bearing life. FMC recommends between .002" tight to .005"
loose of internal axial clearance (end play) when properly
assembled. The final adjustment must be verified using a
dial indicator as shown in the following steps.
NOTE
Too tight of end play will cause higher friction and operating
temperature. Too loose of end play will cause excessive vibration and
noise.
22. Turn the crankshaft more than two revolutions to ensure the
connecting rods (3) are loose and that there is no binding in
the rod bearings; the wrist pin joints are free; and the
crossheads move freely in the power frame.
