Assemble Steering Metering Unit
| NOTICE |
|---|
Make sure all of the parts of the hand metering unit are clean and free of dirt and foreign material. Put clean hydraulic oil on all of the parts. |
1. Install spring (4), ball (3), seat (2) and plug (1) in housing (5).
2. Use tool group (A) to install the lip type seal in plate (6) with the lip of the seal toward the outside as shown.
3. Install seal (8), bushing (7) and the O-ring seal in plate (6). Make sure the open end of bushing (7) is up when installed.
4. Put plate (6) in position on housing (5) and install the bolts to hold it. Tighten the bolts to a torque of 250 lb.in. (28.3 N·m).
5. Install race (11), bearing (10) and race (9) in housing (5). Make sure that the bearing is between the races.
6. Install six springs (14) in spool (12) with three springs on each side. Make sure the curves of the springs are in contact and in the center of the spool. The notched side of the spring ends must be up.
7. Install sleeve (13) over spool (12) so the notch (slot) in the bottom of sleeve (13) engages with the ends of springs (14). Install the pin that holds the sleeve and spool together.
8. Install sleeve (13) in housing (5).
9. Put plate (16) in position on housing (5).
NOTE: The plate will fit on the housing one way only.
10. Install drive (15) in housing (5). Make sure the notch (slot) in drive (15) is engaged with the pin that holds the sleeve and spool together.
11. Install spacer (18) and gear set (17).
NOTE: Make sure the gear of gear set (17) is in alignment with pin (19) as shown. Pin (19) is the pin that holds the sleeve and spool together.
12. Put cap (20) in position and install the bolts to hold it. Tighten the bolts to a torque of 250 lb.in. (28.3 N·m).
