SAFETY
PROCEDURE
Axle Removal
1. Place water trailer on firm and level ground (Figure 2). DO
NOT place trailer on soft or uneven ground. Soft or uneven
ground will not allow for secure placement of hydraulic jack
or jack stands.
Figure 2. Trailer Placement
2. Position a hydraulic jack behind the tire, using the frame
(only) as a lift or contact point.The use of a wood block
is acceptable to extend the height of the hydraulic jack.
NOTICE
Only qualified personnel with proper training should
perform this installation. Follow all shop safety rules
when performing this installation.
NOTICE
The following step-by-step procedures are provided to
assist in the removal and replacement of the tandem
electric axle assemblies used on the Multiquip Water
Trailer models: WTE5C and WTE5HP. Both axle
assemblies will be replaced.
NOTICE
Secure trailer in accordance with Job Hazard
Analysis (JHA) 20140618-002, Securing Trailer for
Maintenance/Repairs.
3. Raise the trailer until the tire is no longer contacting
the ground. The tire should be able to freely rotate
while maintaining a minimum clearance between the
ground and tire.
Figure 3. Jacking The Trailer
4. Next, place jack stands underneath the trailer frame.
5. Remove the tires (4) - break the wheel lug nuts (5) loose
with a ratchet (or breaker bar) and socket.
Figure 4. Removing The Tire
6. Save the lug nuts they will be used later.
7. Locate the wiring harnesses along the right and left
side of the trailer rails beneath the trailer frame.
NOTICE
DO NOT attempt to raise the trailer by jacking on
the axles or the suspension. This will cause damage
to the axles or suspension. ALWAYS place the jack
underneath the frame to prevent bending or deformation
of the axles or suspension.

9. Loosen axle hex nuts (P/N 29249) as shown in
Figure 6.
Figure 6. Loosening Axle Hex Nuts
10. Loosen the axle mounting screws (P/N 29248); it
may be necessary to gently tap the screw (Figure 7)
to advance the splines of the screw.

place the axle so that the brake wires (Figure 10) are
oriented towards the rear of the water trailer.
Figure 10. Brake Wire Orientation
2. Align the new axle assembly ((P/N 29396) with the
hanger on the frame and equalizer as shown Figure 11

axle nuts to secure new electric brake axle assembly.
4. Fasteners should be only be hand-tightened at this
time.
5. Use a ratchet and wrench to tighten axle mounting
screws (P/N 29248) and hex axle nuts (P/N 29249) as
shown in (Figure 12). DO NOT tighten screws all the
way. Leave a 1/16" gap as shown in Figure 13.

Axle Wiring
CURB-SIDE
There are two wires extending from the axle tube as shown
in Figure 15, connect these wires as follows:
1. Using butt connectors (P/N 2540), attach the two wires
coming from the axle tube to the two wires coming
from the hub wire harness (Figure 15).
Figure 15. Curb-Side Wiring
STREET-SIDE
There are two wires extending from the axle tube as shown
in Figure 16, connect these wires as follows:
1. Using splice terminal connectors (P/N 19761), attach
the two wires coming from the axle tube to the two
wires coming from the hub wire harness (Figure 16).

WHEEL MOUNTING
Lug Nut Torque Requirements
It is extremely important to apply and maintain proper wheel
mounting torque on the trailer. Be sure to use only the
fasteners matched to the cone angle of the wheel. Proper
procedure for attachment of the wheels is as follows:
3. Start all wheel lug nuts by hand.
4. Torque all lug nuts in sequence. See Figure 18. DO
NOT torque the wheel lug nuts all the way down.
Tighten each lug nut in 3 separate passes as defined
by Table 2.
5. Check to see if the lug nuts are tight after the first 10, 25
and 50 miles of driving and before each tow thereafter.
Figure 18. Wheel Lug Nuts Tightening
Sequence
NOTICE
NEVER use an pneumatic air gun to tighten wheel
lug nuts.
Over-tightening lug nuts will result in breaking the studs
or permanently deforming the mounting stud holes in
the wheels.
WARNING
Lug nuts are prone to loosen after initial installation,
which can lead to death or serious injury. Check all
wheel lug nuts periodically.
