Disassembly
1. Requires removal of all items beginning on
page 14.
2. Remove the swashplate (40) and pump
cylinder block assembly (69) as a single
item.
3. Separate the pump cylinder block assembly
(69) and the thrust bearing (65) from the
swashplate (40) and set aside.
NOTE: Removal will be aided by applying a
small amount of pressure on the trun-
nion mounted swashplate towards the
center section. While CAREFULLY
removing the swashplate and block as-
sembly, keep the block face flush with
the center section to minimize damage
to the running surface.
Inspection

bearing assembly (65) for wear or damage.
