Assembly & Installation Procedures

1. Upright and Cross Beam Assembly

A) If using pre-existing base rails ensure that the center to center (fore and aft) distance is

22” and that there are two pairs of slots in the base rails that are 20-5/8" apart (side to

side) Otherwise contact your local dealer for proper base rail selection and installation.

B) Place the uprights into the base rails with the decals facing the rear of the truck.

Secure the uprights to the base rails using the 1/2-inch diameter clevis pins and

secure using the large hairclips in the hardware bag.

All Products limited to Vehicle Tow Rating, see Vehicle Owner’s Manual. Visit www.huskytow.com for Warranty Information / Tech Support /

C) Install the Cross Beam.

NOTE: - The Cross Beam is adjustable in both the Vertical and the Fore & Aft

directions. 4 Sets of holes in the ends of the cross beam provides 3-9/16” of vertical

adjustment in 4 steps of 1-3/16”. 3 Sets of holes in the Upright (item 17) provides 2-

1/2” fore and aft movement from the center line of the Uprights.

IMPORTANT:- The Center of the 5thWheel Hitch should be positioned between 1”

and 3” forward of the Center of the Rear Axle.

D) Find the center line of the rear axle and mark on the upright. Measure 2” forward of

the mark and put a 2nd mark on the upright. Find a set of bolt holes in the upright and

cross beam which positions the center of the cross beam as close as possible to this 2nd

mark, while always keeping the center of the cross beam forward of the rear axle.

All Products limited to Vehicle Tow Rating, see Vehicle Owner’s Manual. Visit www.huskytow.com for Warranty Information / Tech Support /

E) Once you’ve found the horizontal position for the cross beam, next find the vertical

position for the cross beam.

NOTE: - If the Trailer is available for measuring follow the instructions in the section

“Operating Instructions” sub section “Preparing For First Use”. Otherwise put the

Cross Beam in the highest position per instruction (F).

F) Put the cross beam in the highest position using the pattern of holes on the end of the

cross beam. Place a flat washer, lock washer and nut on each bolt & finger tighten.Add

shims as necessary to fill gaps. Snug down the four nuts using an "X" pattern. Torque the

nuts to 110 ft-lbs. Note: Be sure that the Cross Beam straddles the uprights. Do not

over tighten, as this will cause the uprights to fit improperly in the base rails.

Use only the supplied bolts, nuts, and washers to install this kit. All nuts and bolts

are Grade 8 unless specified otherwise.

G. Shims 32043 are provided to adjust crossmember and uprights. Use only if needed

for proper alignment.

Place shim on either side

as needed

3. Handle Assembly

A) Attach the handle with the 3/8” Carriage Bolts, lock washers and nuts. Torque the nuts

to 23 ft.-lbs. Ensure the padlock hasp points down as per the sketch.

2. Head and Yoke Assembly

A) Install Head & Yoke with pivot pin and castle nut. Tighten the castle nut until all the fore

and aft movement is eliminated in the pivot pin and in the head and yoke assembly. This

may require 60mm wrench or pipe wrench. Continue to tighten the castle nut until the

safety pin can be inserted. Close the clip on the Locking Clevis Pin to secure the nut.

B) Using a grease gun, grease Zerk fitting on the plate side of the pivot pin.

Understanding the Safety Features of your New HUSKY 5th

Wheel.

This Husky 5th Wheel Hitch has new features which add to the safety and ease of

operation. The most important feature to understand is that the Hitch will only fully close

when the King Pin of the 5th WheelTrailer is located correctly inside the Hitch.

Before using this 5th Wheel Hitch for the first time, the Operator needs to understand the

operation of the safety features of this Hitch.

A) Pull the Handle fully out, and then let it slide back while pushing it gently forward

towards the cab of the truck to miss the latch. The Hitch should partially close.

B) Looking on the front of the Hitch, the indicator should be as shown in the sketch above.

C) Using a Stick, (Keep fingers out of Jaw area) press on the Trigger Plate located

underneath the Jaw. Pressing on the Trigger Plate will release the jaw mechanism and it

will fully close. The Lock Hasp Indicator should now show that the Jaw is closed.

After the test, pull on the handle all the way out to reset the Latch Mechanism

WARNING

CLOSING THE HITCH BY TRIPPING THE TRIGGER PLATE SHOULD ONLY BE

DONE AS A TEST. IN NORMAL OPERATION LEAVE THE HITCH OPEN UNLESS

IT IS COUPLED TO A TRAILER.

THE TRAILER.

Operating Instructions

About Your Husky 26K W 5th Wheel Hitch

The Husky 26K W 5th WheelHitch System is designed to tow 5th WheelTrailers with a Gross

Vehicle Weight Rating up to 26,000 lbs. Do not exceed the rated GVWRof your vehicle as it will

create an unsafe towing condition. It has a 4-way swivel head, its height is adjustable from 15.75

to 19.25 inches in 1-3/16-inch increments and is removed from the bed of the truck by pulling 4

retaining pins.

Preparing For First Use

Your Husky 26K W 5th wheel system is now installed and you're anxious to be on your way down the

road. You're almost there but take a few minutes to ensure your hitch is set up properly for your

particular truck/coach combination by following the steps below.

1. Verify that the cross member is set at the proper height to provide a minimum of 6" clearance

between the bottom of the trailer nose and the top of the truck bedsides and allows for a level-

towing attitude of the 5th WheelTrailer (See Figure 1 below).

Figure 1

With top face of head level measure up to top of pickup box (dimension Y in Figure 1). On

the trailer measure up from the face of the pin box to the underneath of the trailer

(dimension X in Figure 1). Measurement X less measurement Y gives the amount of

clearance between the top of the pickup box and the underneath of the trailer.

At a minimum this should be 6”, if the trailer and tow vehicle are going off-road then this

needs to be 8” to 10”.

If this dimension is less than 6” DO NOT USE THIS TRAILER

WITH THIS TOW VEHICLE. Severe damage may occur to both the

pickup box and the trailer.
