JABSCO Hy-Line User Manual

For LH32 and LH34 models:
Do not fit gear drive key, gear, tab
washer or gear nut. Instead fit tab
washer (7a) and bearing nut (8a).
Tighton the bearing nut by hand to hold
the assembly in place, taking up any
end float. It may help to warm the inner
ring of the rear bearing to ease fitment
onto the shaft.
d) Rotate the shaft a minimum of 4 times
and tighten the gear nut (8) again by
hand. (Bearing nut (8a) for LH32 and
LH34 models)
e) Rotate the shaft a further 4 times,
tighten the gear nut again by hand and
then tighten the nut a further quarter
turn, using the C-Spanner. (Bearing
nut 8a for LH32 and LH34 models)
f) Rotate the shaft 4 more times and
torque the gear nut (8) to the figure
shown on the performance data sheet.
Repeat two-three times until no further
tightening of the gear nut is perceived.
(Bearing nut (8a) for LH32 and LH34
models)
g) Repeat c) to f) for drive shaft. Note:
when fitting the second gear, align
gear timing marks. (See figure 24).
DO NOT fit gear (6) on LH32 and
LH34 models.
h) Check that there is no perceptible
movement of either shaft in any
direction and FINALLY BEND OVER
TAB WASHERS to lock the gear nuts.
For LH32 and LH34 models:
Before carrying out instruction i) fit the
gear drive keys (28), gears (6), tab
washers (7) and gear nuts (8). Ensure
that the timing marks (see fig 24) are
aligned. Tighten the gear nuts to the
torque shown on the Performance
Data Sheet. Finally, bend over the tab
washers to lock the gear nut in place.
i) Front oil seals (23) should be pressed
in, until they are flush with the front
face of the bearing housing (1). Take
care not to curl or damage the lip or
displace the gaiter spring on the shaft.
Ensure they are square to the shaft
(not tilted).
