Stroke Control Housing, and Knob Replacement (refer to Dwg.
440.400.000.010B)
Reverse the above removal procedures for the replacement of the
items mentioned above; however, the following additional procedures
must be adhered to:
a. Tighten the pre-load nut (17) (removed in step j above) just
enough to eliminate axial movement of the eccentric assembly.
The eccentric shaft (45) must slide in and out without any
binding.
NOTE: Pumps with an Electric Stroke Positioner do not have detent
stroke mechanism. For pumps with an Electric Stroke Positioner,
proceed to step e. For pumps with a Manual Stroke Positioner,
proceed to step b.
b. Refer to Dwg. 440.400.000.030 for the next two steps, c and d.
c. Screw the carrier bearing (22) to the stroke adjust housing (25)
up to the edge of the two holes for the detent pawls (52). Position
the two holes so that they are horizontal.
d. Lubricate with silicone grease and install the spring, followed by
the pawl, into the holes and hold them in position. Continue to
turn the carrier bearing clockwise to secure the pawls.
e. Turn the carrier bearing (22) clockwise until it stops. The bearing
(19) must be against the eccentric shaft (45) shoulder before
tightening the screw (21) (removed in step c above).
f. Set the stroke position to approximately zero by turning the car-
rier bearing (22) counterclockwise until it stops. Then rotate the
carrier bearing one turn clockwise.
g. Place a dial indicator with a magnetic base on top of the gearbox.
Set the indicator shaft to indicate the eccentricity of the sheave
(46), as shown in Figure 4-1.
