FINAL INSPECTION
1 . Check for end play (in and out) of nozzle housing on the axis of
the tee housing nose . There should be some free play .
2 . Check end play (up and down) of tee housing .
3 . Rotate the rotor with your finger or a small screwdriver . The rotor
should rotate freely and the tee housing should begin to move
slowly .
NOTE: If you get negative results on any of these final inspections then
refer to the Trouble Shooting Guide that begins on page 13.
STATOR INSTALLATION
Place the stator (8) into the inlet stem (3) by rotating slightly until the
weld on the I .D . of the inlet stem is in between 2 of the fins of the
stator . The weld on the inlet stem keeps the stator from rotating . The
stator retaining ring (39) can now be installed using a pair of needle
nose pliers .
PROBLEM SOLUTION
Excessive Tee-housing bearings wear
Visually inspect the bearing for cracks or signs of corrosion . Check the bearing clearance
between the I .D . of the cup (31 & 33) and the O .D . of the bearing . If the bearings show signs
of wear from deposits, sediment or other foreign matter, or have excessive side to side
movement in the bearing cup, replacement is recommended .
Excessive gearbox bearing wear
If there is excessive side to side play of one of the gear shafts (17, 18, and 21) and one of the
mating bearings (26, 27, 28, 29, and 30) then replacements is recommended .
Poor cleaning performance
Water Pressure & Flow: Is there sufficient pump pressure or water flow at the tank cleaner?
Minimum operating pressure is 30-40 psi measured at the inlet of the machine . Minimum pipe
or hose diameter is 1 ½" I .D .
Nozzle Housing Rotates Slow or Not At All: Upon inspection of the nozzle housing bearings
(33), is there a buildup of deposits, sand or scale? Inspect the seals (36) for signs of wear .
Replace bearings, cups and seals as necessary . If the nozzle housing cups, bearings and seals
need replacement or cleaning, it follows that the tee housing cups, bearings and seals will also
need the same .
Erratic rotation of nozzle housing
If you are able to observe the machine in operation and notice the nozzle housing rotating,
then stopping briefly, then rotating again, this could be symptoms of the following:
• Clutch o-ring is worn or corroded and is not seating completely against the nozzle
housing bevel gear .
• Damaged bevel gears (10, 11): inspect the bevel gears for bent or excessively worn teeth .
If the teeth are worn down approximately 25%, or if one or more teeth are bent, then the
bevel gear(s) should be replaced .
Worn clutch o-ring
Inspect the clutch o-ring (49) condition . If the clutch o-ring is cracked, or if corrosion has
shrunken it in size and it is not filling the o-ring groove on the nozzle housing completely, then
replacement is recommended .
Nozzles clogged
Inspect the nozzles for obstructions by solid particles trapped in the stream straighteners (13) .
Use Teflon tape on nozzle threads prior to re-assembly .
