Hydraulic Oil Change Cont.
17. It’s time to remove any potential air pockets in the hydraulic system. With the hydraulic system correctly reassembled, start the Mudd-Ox
and run at 1,500 RPM for a minute. Get the oil to operating temperature. Then, slowly raise the RPM’s a few hundred at a time. If there is a
“rattle” noise coming from the hydraulics, that is air in the system. Immediately bring the RPM to idle for a minute. Then try again. During
this time, have another mechanic monitor the hydraulic oil tank level. If the oil level falls below the sight glass, fill up immediately.
18. Once the machine will go through the entire RPM range in neutral without rattling, you may begin with the control levers. Slowly move the
control levers forward approximately an inch. Run for a minute. If there is no air, continue moving forward in steps. If the hydraulics begin
to rattle, bring back to neutral for a minute then try again. Repeat for control levers in reverse. Then slowly move control levers backward.
Continue to move the control levers with varying degrees of stroke.
Note:
It is
very
important to not “drive” against the air as this will
damage the pumps. Once the Mudd-Ox can be driven in both directions without any air, shut off and let the oil temperature completely cool
down.
19. Carefully lower the Mudd-Ox to the ground. Reinstall engine cover. Now, proceed to get inside the vehicle and start up. Get to operating
temperature. Slowly begin to drive around a controlled environment such as flat ground. Listen and feel for air in the hydraulic system; the
machine will feel “tight” if the pumps have air. If there is air,
do not
attempt to drive against it. Work the control levers as in step #18.
20. Once the Mudd-Ox can be driven on flat ground in both directions without any air, attempt to drive on small grades both up and down. Also
attempt to counter-rotate the Mudd-Ox by pushing the control levers in opposite directions. If there is no air, the oil change is complete.
