Instruction Manual for F1300/1600 Mud Pump
26
When installing the pinion shaft assembly on the pump, observe the following precautions:
a)
Insure pinion bearing carrier gasket (1) and oil seal carrier gasket (2) are in place and in good
condition.
b)
When installing the bearing sleeve (3) and the cover (4), make oil collecting groove face to (7)
and correctly align with oil return bore.
c)
Remove burrs, dents or gouges from the outer surface of the anti-wear sleeve (5) before sliding
cover (4) into place. When sliding lip of seal over end of shaft exercise care to prevent it from being
damaged by the sharp edge of the keyway. Also pay particular attention to insure oil seal lip IS NOT
TURNED by edge of the sleeve when sliding seal into the anti-wear sleeve.
d)
Tighten bearing bolts (6) with the approximate torque 110
～
215N.m (80-160ft .lbs)
e)
Check condition of the pinion bearing inner and outer races and rollers. If there is any indication
of galling, flaking or grooving, or if diametric clearance exceeds 0.3mm, it is recommended the entire
bearing be replaced.
3.4 Crankshaft Assembly
The crankshaft assembly consists of the crankshaft, gear ring, connecting rod with bearings, and the
main bearings. The running clearances of the bearings are predetermined by their precision fit to the
shaft and their respective bores. When performing any maintenance or overhaul, make sure the fit
shown in Table 3 are obtained.
