14. Lift the crankshaft until it is free of all
main bearings. Continue until bearing
faces of crankshaft reaches next
bearing. If crankshaft does not slip
through bearings freely, push rollers
into race. If bearings are extremely
loose and worn, it may be necessary to
install spiral lock pins (refer to Special
Tools section of the Parts Manual) to
hold rollers in place. Continue until
crankshaft is clear of all bearings.
15. Remove bearing retainers from the
frame.
16. Set power frame back on mounting feet
before removing main bearings.
NOTICE
As the two end bearings are 0.050”
larger than the center bearings, it is
advisable to remove the right end
bearing and center right bearing out
the right side of the frame and the left
end bearing and center left bearing
out the left side of the frame.
17. With bearing locks removed, bearings
may be driven out of bore with a
hammer and brass or aluminum blunt
nosed drift punch.
WARNING
Do not drive against rollers or
bearing cage. Drive only against the
bearing race, as severe damage to
the bearings could occur.
WARNING
When reassembling the crankshaft
assembly, make sure to follow these
steps:
1. Pack the bearings in dry ice
before assembling in the frame.
2. Slightly heat the inner bearing
races before installing on the
crankshaft.
3. Braze the retaining rings on the
crankshaft after installing the
inner bearing races. Avoid
direct contact with the inner race
or the crankshaft.
4. Reinstall the safety wire for the
bolts
holding
the
splined
coupling to the crankshaft.
Failure to follow these directions may
result in serious damage to the
pump.
