Assembly
NOTE: When assembling the motor, check the identifi-
cation marks made during disassembly to make sure
the parts are properly aligned during assembly.
1. LubricateO--rings,pressureseals,back--upgaskets
and seal grooves with a thin coat of petroleum jelly. Lu-
bricate all other internal partsfreely with clean hydraulic
oil.
2. Install new shaft seal into front flange.
3. Install lubricated pressure seals into the grooves in
the front flange and rear cover. Follow by carefully plac-
ing the back--up rings into the grooves.
4. Install new O--rings to the body.
5. Lubricate gear faces and bearing surfaces of drive
gear, idler gear and bearing blocks. Carefully assemble
bearing blocks and gears noting identification marks
made during disassembly.
6. Position the motor body on its side. Carefully slide
bearing block and gear assembly into the body cavity
using identification marks made during disassembly.
7. Remove any excess lubrication from mating sur-
faces of body, rear cover and front flange. Make sure
that these surfaces are clean and dry.
8. Install dowel pins in body.
IMPORTANT: Do not dislodge O--rings, pressure
seals or back--up rings during final assembly.
9. Gently slide the rear cover onto the assembly using
marker or scribe mark for proper location. Firm hand
pressure should be sufficientto engage the dowel p ins.

12.Place motor front flange in a vise and alternately
torque the cap screws from 215 to 280 in--lb (24 to 32
N--m).
13.Put a small amount of hydraulic oil in port on motor
and rotate driveshaft one revolution. Protect the shaft if
using a pliers. If drive shaft binds, disassemble motor
