1) Install gear ring and check run-out.
Thoroughly clean mating faces of gear ring and crankshaft flange, fasten gear ring into position with
bolts. Tighten flange bolts (2) to the torque: 2455 N.m (1810ft .lbs)
Install a set of roller bearing on both ends of crankshaft, and measure gear ring face run-out with dial
indicator. Because of the effect of roller bearing clearance, it is required to measure synchronously on
shaft end and gear end face with dial indicator; the real run-out on any position is the D-valve of the
two readings. When the run-out exceeds 0.224mm (0.0088in), take down gear ring and check the
reason of over D-valve.
2)
Install the outer races of the connecting rod bearings (13) and the outer race retainer ring (3) in
the three connecting rods separately. Outer retainer ring should be installed as following: when the
pump is at the middle strokes, oil collecting ring should be at the bottom; tighten bearing retainer
bolts (4) with the torque 75 N.m (55ft .lbs) and lock with wires. NOTE: The inner/outer races and
rollers of the connecting rod bearings are matched by group and must not be intermixed.
3)
Install the outer race of the crosshead bearings (19) into three connecting rod small ends .It is
preferred that the outer race assembly be “pressed” into position of frozen in “dry ice” (CO2) or a
deep freeze until it can be inserted into the bore. Under emergency circumstances, the outer race
assembly can be installed by using a large torch and heating the eye of the connecting rod. DO NOT
EXCEED 149 (
℃
300°F) (Use TemilStick) and DO OT USE WATER to cool the strap.
NOTE: The inner and outer races of the crosshead bearings are matched by group and
