Maintenance & Adjustments
Danger! All power sources including water pumps must be disconnected and
secured before performing any maintenance or adjustments on your
water-Reel. Failure to disconnect all power sources before performing
maintenance or adjustments may result in machine damage, personal
injury, or death.
Runner Clearance:
The clearance between the runner vanes and the volute wear ring is set at
the factory at 0.045” which is satisfactory for most irrigation applications and
normally should not be changed. If runner adjustment becomes necessary:
A. Remove the faceplate, by removing eight 3/8” nuts from the bolt circle
B. Remove the 5/8” runner lock nut.
C. The runner is adjusted on the shaft by adding and removing spacers on
the backside of the runner. The 5/8” runner lock nut must be replaced
with a torque of 75 ft. lbs each time the spacers are added or removed.
First adjust the runner on the shaft (with the faceplate held in place and
without o-ring) until a slight metal to metal contact is heard as the runner is
turned. This establishes a zero clearance point. To set the clearance to
0.045” for clean water, remove one 0.045” spacer on the runner shaft.
Replace the 5/8” runner lock nut and torque to 75 ft. lbs. “Caution”
Excessive runner clearance decreases turbine power capability of the
water motor.
D. Replace the faceplate o-ring and 3/8” nuts.
