D. INSTALLING NEW SEAL ASSEMBLY (#4)
(DO NOT UNWRAP THE NEW SEAL ASSEMBLY UNTIL YOU ARE READY TO INSTALL. ALL
PARTS OF THE ASSEMBLY ARE PACKED IN SEQUENCE OF INSTALLATION.)
1. To replace seal assembly (4), perform above operations under cleaning and remove pump casing (5)
by removing the four bolts (7B) holding casing and the casing bearing (7) to the pump frame (15).
2. After cleaning all parts including pump shaft, begin reassembling the pump. Install grease retainer
seal (6) with cavity portion of seal facing inward. Rebolt casing and casing bearing (7) onto clutch
housing using the four cap screws (7B). Using a light oil lubricant (3 in 1), install ceramic seat with
its neoprene holder into the seal recess making sure it is square with the shaft. Lubricate inside of
bellows assembly with a light oil and verify that the steel ring is stuck (glued) to end of assembly.
Slide bellows assembly onto the shaft and push until the steel ring is against the ceramic seat.
3. Install seal spring on hub of impeller. After coating threads on the pump shaft with an anti-seize
compound, install impeller - seating it securely.
4. Utilizing rubber O-Ring gasket (2) reinstall suction cover using the eight cover bolts (5B). At this
time, check to see that pump runs freely. If impeller rubs cover plate, either impeller is not tight on
the shaft or cover plate needs readjustment - see “impeller clearance”. Tighten these bolts uniformly
using 15 ft. pounds (165 kg/m) on the torque wrench.
5. After reinstalling suction pipe assembly, lubricate and tighten victaulic clamps. Service automatic
lubricator.
TROUBLE SHOOTING YOUR HYDROSEEDER®:
Because of the tremendous work load usually placed upon the HydroSeeder®, minor malfunctions will
occur from time to time. If not remedied immediately, they could lead to poor performance and damage to
the equipment. This section describes possible problems and the action to correct them.
1. Foam in the tank and air entrainment.
The mixture of dry materials with water will sometimes cause excessive foaming while others will
cause air entrainment. This is exhibited by erratic discharge and/or a drop in pressure and distance.
Some solutions are:
A. As the slurry level drops in the tank, slow the agitator.
B. Add 2 or 3 ounces (4 to 6 cl) of an antifoaming agent to the tank.
C. If you can determine which additive is causing the air problem, either add it last or not at all
- unless it’s the water.
D. Reduce recirculation time as much as possible.
2. Plugging or clogging:
DANGER: Turn off engine and disconnect battery cables before working
on equipment. Serious injury or death can result from moving
parts or high pressure spray.
