Assembly
Step 27
Turn the rear flange over and
place it on the housing. Lower
the flange in place so that the
bolt holes are aligned.
Step 28
Insert a 16mm x 45mm socket-
head cap screw 114978-045 in
each of the four bolt holes;
tighten them to 145±10 n/m
(107±7 lb-ft).
Step 29
Turn the assembled housing
and flange so that the rear
pump shaft is horizontal.
Step 30
Measure the shaft end play:
Place a dial indicator with a
magnetic base on the face of
the rear flange, and set the
rod tip on the end of the rear
pump shaft.
Step 31
Tap the end of the shaft with a
rubber mallet, and set the dial
indicator to zero. Then tap the
other end of the shaft and record
the result.
Step 32
Subtract 0.05mm from the
recorded measurement; this will
be the thickness of the required
shim stack.
Step 33
Loosen the cap screws 114978-
045 from the rear flange, then
remove the flange from the
housing and set it aside. Hold
the swash arm in place with a
locking C-clamp.
Step 34
Combine shims to reach the
required thickness.
Step 35
Remove the taper bearing cup
from the flange, and place the
shims in the bearing bore. Set
the bearing cup back in place on
top of the shim stack.
Step 36
Set the rear flange on the housing
again; insert the cap screws
114978-045, remove the locking
clamp, and tighten the cap
screws to 145±10 n/m (107±7
lb-ft).
