NOTE
The cylinder block assembly usually comes out in one piece; however, some of the parts can
separate. This does not present a problem as these parts can be assembled later.
n.
The swashplate (35) has a notch which locates over a pin (36) in the housing (37) to prevent improper assembly;
however, mark the housing for proper orientation of the swashplate during assembly.
o.
The fixed swashplate (35) and shaft assembly can now be removed by grasping the shaft (34) and lifting both
parts out of the housing.
p.
The tapered bearing (38) can be pressed off the shaft if required. Be careful not to damage the seal diameter of
the shaft while removing the bearing. The bearing race (39) is press fit in the housing (37).
4-10.1.2 Inspection and Repair
a.
It is recommended that the entire shaft seal (4-9) be replaced. If, however, the seal is being reused, inspect
each part separately for damage.
b.
Clean metal parts by using a solvent wash and air drying.
c.
If the shaft (34), bearings (19 or 38), end cap (12) or housing is replaced, the shaft end play must be checked.
d.
To check the shaft end play, assemble the shaft (34) and bearings (19 and 38), housing (37), end cap (12) and
gasket (40). The shaft end play should be from .006" to .016". If adjustment is necessary, a shim (21) can be
placed under the bearing race (18) in the end cap (12).
4-10.1.3 Assembly.
a.
Place the fixed swashplate (35) over the shaft-bearing (34, 39) assembly and place into housing (37) locating the
notch in the swashplate on the pin (36) in the housing.
b.
Prior to assembly of the cylinder block, inspect the pistons (33) for contamination or excessively worn slipper
pads. Replace any pistons that are found to be defective.
c.
To install the cylinder block assembly it is necessary to check the alignment of certain parts. There is no special
relationship of pistons to bores, springs, etc. However, the alignment of the ball guide (31) and cylinder block
splines is critical. The undersized tooth in the spline of the cylinder block (23) must line up with the missing tooth
in the ball guide (31) spline.
