HYDRAULIC SYSTEM MAINTENANCE. (cont)
Pump Assembly. (Sheet 14 of 23)
Using feeler gage, measure gap
between body (118) and cover
(100, Figure 10-49) without
shim(s). Measure at four bolt
(98) locations. Note the average
thickness and add 0.008 inch.
This will be the total shim
thickness to be added to cover
without shim(s). If the
thickness of shim(s) required is
less than 0.005 inch and more
than 0.025 inch, add thickness of
the shim(s) required from feeler
gage measurement plus 0.008 inch
to the 0.015 inch shim thickness
of the other cover. Divide the
total thickness of the shim(s)
evenly and install the same
thickness of shim(s) on each
Remove four of eight bolts (98),
lockwashers (99) and the cover
(100, Figure 10-50) without
Thickness of one shim is
0.00473 inch and thickness of
other shim is 0.00197 inch.
Position shim(s) (102 and 101) on
cover (100, Figure 10-51) at
thickness determined in step 16.
Install remaining new preformed
packing (103), cover (100),
remaining four of eight
lockwashers (99) and bolts (98).
Tighten four bolts (98) to 32
ft-lb torque. Swashplate (132)
must move freely after four bolts
(98) are tightened.
