DRIVE
TRAIN - Thrust Bearing Installation
 |
1.
Install the WTC and place the 3/16" i.d.
tubing used in the stern bearing installation on the
WTC drive shaft. Slide it aft on the drive shaft until
it meets the thrust bearing bulkhead. Make sure the
tubing doesn't droop as it slides, but stays inline
with the shaft. With a sharpie, draw a circle around
the tubing on the bulkhead.
|
 |
2.
Remove the WTC. With a 5/16" bit, drill
a hole for the thrust bearing through the circle mark
on the bulkhead.
|
 |
3.
Place the thrust bearing into the hole from the
stern side as shown. Slide the propeller shaft into
the stern bearing and forward through the thrust bearing.
Reinstall the 3/16" tubing on the WTC drive shaft.
Slide the prop shaft into the tubing.
When
coupled, the WTC drive shaft and prop shaft should
form a straight line through the thrust bearing bulkhead
to the stern bearing. If necessary, widen the thrust
bearing hole with a round file to ensure a non-binding
fit. |
 |
4.
Mix a batch of 50/50 epoxy and micro-balloons. Slide the
thrust bearing out of the bulkhead. With a brush, apply
epoxy around the bearing. Slip the thrust bearing into
the bulkhead. Avoid getting epoxy in contact with the
prop shaft. Allow to cure overnight. |

Grease
Is The Word
The
bearings supplied with your kit are oil impregnated
"oilite" bearings. As the shaft hets the bearings
during operations, oil is released by the brearing to
assist in lubrication. We do recommend, however, applying
a good, waterproof bearing grease to the shaft where
it contacts both the stern and thrust bearings.
