C. Replacing Hydraulic Fluid in the Pump (continued)
9. replace reservoir onto the bottom of the pump using new seals. replace and tighten screw in
bottom of reservoir.
10. Re-attach the pump onto the base casting and re-attach the hydraulic lines and electric power.
11. Put 22 ounces of fresh hydraulic fluid into the pump through the dip stick hole and replace the
dip stick.
12. run the booms up and down three or four times. Wait approximately 5 minutes and, with the
booms down, check the fluid level. The fluid level should not show on the stick because
approximately 12 ounces of fluid have been replaced into the lines and hydraulic cylinder.
13. Add 10 ounces of fluid and re-check the dip stick. To avoid having to screw the dip stick in all
the way while adjusting the fluid level, the lower line of the two "full" lines may be used for you
reading.
14. A couple of more ounces of fluid may have to be added to bring the fluid level to the full mark.
When the full level is obtained, screw the dip stick in completely and seat the "o" ring.
D. Replacing the Hydraulic Cylinder
elbow adapter fittings (30 & 31) are provided on replacement hydraulic cylinders.
The elbow
adapter with restricted orifice (30) should not be removed from the cylinder for any reason.
Wearing
safety glasses and protective clothing, you may use the following procedure to change the hydraulic
cylinder:
1. make sure the latch (9) is securely in place. As a precaution, secure the booms to the apparatus
so they cannot come down on their own.
2. remove the fluid lines (see figure 15, page 19) from the elbow adapter fittings.
Do not
remove the elbow fittings from the cylinder.
Place the open ends of the fluid lines into a
receptacle to catch the fluid.
3. Loosen the socket head cap screw on the lower side of the top clevis clamp.
4. remove pin (57) from the lower clevis clamp.
5. Turn the cylinder counterclockwise to remove the cylinder ram from the top clevis clamp yoke.
6. replace the cylinder and turn clockwise to re-attach the cylinder ram into the top clevis clamp
yoke.
7. replace pin (57) through the lower clevis clamp.
