Figure 16. Motor Cylinder Block Assembly Tool
2.250 inch
1.125 Radius
6.000 inch
Break sharp edges, both sides
Use 28 gauge
sheet metal
NOTE: To hold bypass plate (38) in po-
sition, apply a small drop of grease to its
slot before installing.
8. Install spacer (27), 16T pinion gear (28),
washer (82), snap ring (83), and washer (82)
onto motor shaft (24).
9. Insert the motor shaft assembly far enough to
seat the motor cylinder block (21).
10.Install piston washers (18), springs (17), and
pistons (16) in cylinder block (21).
11. If not already available, make an assembly
tool from 28 ga. sheet metal as shown in Fig-
ure 16. The assembly tool must be free of
burrs and rough edges.
12.Using the assembly tool to compress pistons
(22), install cylinder block assembly (21). Be
careful not to dislodge bypass plate (38) when
installing the cylinder block assembly.
13.Again using the assembly tool to compress
pistons (22), slide thrust bearing (25), behind
the tool, into its cavity in front of the cylinder
block (21) and assembled pistons.
NOTE: The thick race of thrust bearing
(25) must face the pistons.
14.While holding the cylinder block assembly
(21) and the thrust bearing (25) in place, with-
draw the assembly tool from between the
thrust bearing and the pistons.
15. Install motor thrust bearing retainer (57)
16.Reassemble the planetary differential assem-
