ASSEMBLY INSTRUCTIONS
Unloading the HSL and Final
Assembly
I
n most cases the 7831 HSL has come to you with the
main wheels and tires shipped loose due to shipping
width, restrictions.
1.
Install the main wheels and tires to the hitch rock
shaft hubs
2.
Due to the HSL being a towed implement the tire
tread is typically installed opposite of that of a tread
where power would be applied through it.
For
instructions and specifications on torqueing the lug
nut assemblies,
(See Figure 3-1 and Table 2-1.)
NOTE
There is a protruding step on the hub pilot. The wheel
center plate must fit over the hub pilot and then bottom
out against the hub flange. Failure to get the wheel
properly positioned against the hub face will cause the
wheel to loosen and cause damage to the hub and/or
wheel.
3.
With the tire and wheel assembly correctly positioned
against the hub, begin to tighten the flange nuts
sequentially as shown on decal 3-573-010210 in
to 50 foot pounds.
4.
Re-check the positioning of the wheel relative to the
hub and proceed by tightening the lug nut assemblies
sequentially to 450 to 500 foot pounds.

DANGER
Read and Understand the installation, service and safety instructions manual before installing or
servicing the hub. Failure to do so may result in personal injury or death, and may result in a
compromise of your vehicle’s safety through loss or failure of a wheel or compromise of the braking
system.
Use a torque wrench to assure proper torque, failure to do so will compromise your products service,
life and safety. Under torque and over torque can cause thread and/or nut damage, and may result in
the loss of a wheel.
Recheck torque after the first 50 to 100 miles of service. Parts may seat naturally, causing the torque
to drop. Proper torque is essential for the service, life and safety of this product.
