Ball Coupling Adjustment:
1.
Install coupling over correct size trailer hitch mating ball and
push down on handle until trigger locks in slot.
2.
Pull up and down on tongue to ensure ball fits snug in
coupler. There should be no play between coupler and ball.
3.
Tighten adjustment nut, located on bottom of coupler
opposite the handle, to take up any excessive play.
NOTE:
If nut is too tight, the handle will not lock into position.
Towing Safety and Operational Guidelines:
Follow all safety and operational rules listed in the following
section:
1.
Make sure vehicle is capable of towing the load. Make sure
vehicle hitch is rated for the load.
2.
Make sure the trailer coupler and hitch ball are the same
sizes and rated for the load.
3.
Make sure trailer coupler is correctly and safely connected
to hitch ball. Coupler handle trigger must be positively
locked. Install lock pin (not provided) to ensure trigger stays
locked during towing.
4.
Be sure to use safety chains supplied with trailer. Safety
chains should be attached to towing vehicle at the same
length on both sides and should not drag on the ground.
5.
Never overload trailer. Trailer is rated to carry pump, pump
frame and a full load of fuel. Loading other items on the
trailer may cause GVW to exceed trailer rating.
Maximum safe highway towing speed is 45 mph. Never allow
passengers on the trailer.
6.
Check all lights for proper operation before each use.
7.
Check tires for wear and proper inflation before each use.
Inflate to psi rating on tire.
8.
Check safety chains for wear and solid connection to trailer
frame.

MECHANICAL SEAL REPLACEMENT
NOTE:
Always replace the mechanical seal parts (Ref. No. E6 & E7)
as an assembly (Ref. No. E5) to ensure proper mating of mechanical
components.
NOTE:
Always inspect impeller stub shaft ball bearing (Ref. No. E14)
during seal replacement. The bearing may have been damaged by
leaking water. Refer to IMPELLER STUB SHAFT BEARING
REPLACEMENT section.
1.
Access impeller/seal plate area as described in SLIDING
ENGINE SLED OPERATION section.
2.
Unscrew impeller (Ref. No. E2) from the impeller stub shaft
(Ref. No. E15). Use a rubber mallet or soft block of wood
and hammer to loosen impeller. Remove any impeller shims
(Ref. No. E3), shaft sleeve and seal head (Ref. E6) from
impeller stub shaft.
3.
Remove two 1/2-13x1" cap screws (Ref. No. E12) holding
seal plate (Ref. No. E11) to bearing housing (Ref. No. E17
or E18). Remove seal plate from bearing housing.
4.
Remove impeller shaft washer (Ref. No. E13) and inspect
impeller stub shaft ball bearing for water damage or wear.
Replace shaft washer with flat surface toward impeller.
5.
Push seal seat from the seat plate recess with a
screwdriver.
6.
Clean the seal plate recess before inserting a new seal seat.
7.
Carefully wipe the polished surface of the seal seat with a
clean cloth.
8.
Wet the rubber portion of the seal seat with a light coating of
soapy water.
9.
Press the new seal seat squarely into the cavity in the seal
plate. If the seal seat does not press squarely into the
cavity, it can be adjusted in place by pushing on it with a
piece of pipe. Always use a piece of cardboard between the
pipe and the seal seat to avoid scratching the seal seat.
(This is a lapped surface and must be handled very
carefully).
10.
After the seal seat is in place, ensure that it is clean and has
not been scratched or cracked.
11.
Using a clean cloth, wipe the impeller stub shaft and make
certain that it is clean.
12.
Install seal plate and secure to bearing housing adapter face
with two 1/2-13x1 cap screws.
13.
Apply a light coating of soapy water to the inside rubber
portion of seal head and slide onto the shaft sleeve. Slip the
shaft sleeve and seal head onto the impeller stub shaft with
seal head lapped surface towards seal seat lapped surface.
14.
Replace any impeller shims removed during disassembly.
15.
Screw the impeller back in place tightening until it is seated
against shims and shaft sleeve.
NOTE:
Make sure seal spring retainer is not pinched between
impeller/shims and end of shaft sleeve.
