Mixer Hydraulic Troubleshooting 8.2.3
Step Possible Cause If . . .
1 Remove the din plug, then remove the coil by
unscrewing the nut on top of the coil. With
the coil removed, re-attach the din plug and
energize the coil by moving the mixer switch
to Forward or Reverse, then insert a screw
driver into the center of the coil. Does the
coil magnetize when the din plug amber light
is "ON"?
•
Yes, go to Step 2.
•
No, replace the coil.
2 Is the relief pressure set correctly?
(Refer to Fig. 8-6 Hydraulic Valve
Pressure Setting , for pressure settings.)
•
Yes, go to Step 3.
•
No, first turn "OFF" the Isuzu engine, then
remove one of the two hydraulic hoses
going to the agitator hydraulic motor, cap off
the fitting on the motor and use a 3,000 PSI
gauge with the proper JIC fitting, attach it to
the hose. Start the Isuzu engine, turn "ON"
the main power in the control box, move the
"Mixer" toggle switch to the "Forward"
position and read the pressure gauge. If the
pressure needs to be adjusted use the
pressure relief valve labeled "RVA", loosen
the jam nut and adjust the pressure with the
allen screw at the end of the relief. Turn
clockwise to increase pressure and counter
clockwise to decrease pressure, then
tighten the jam nut to lock the pressure.
Next turn "OFF" the Isuzu engine, remove
the cap and pressure gauge, then re-attach
the hose.
3 Is the hydraulic flow 1.5 GPM from the
hydraulic valve? If you do not have a flow
meter, call a local hydraulic shop to run the
test for you.
•
Yes, call Crafco, Inc. and speak to a
customer service technician you should
have been able to find the problem.
•
No, replace the flow divider in the hydraulic
valve.
4
Is the hydraulic flow correct from the
hydraulic pump? If you do not have a flow
meter, call a local hydraulic shop to run the
test for you. (Refer to
Fig. 8-6 Hydraulic
Valve Pressure Setting for flow rate).
•
Yes, call Crafco, Inc. and speak to a
customer service technician you should
have been able to find the problem.
•
No, replace the hydraulic pump.
