US Hitch Model H10-400 2

• Ratchet drive, extension and T-40 Torx security bit/socket

• 1/2" wrench or socket

• 9/16” wrench or socket

• 3/4” wrench or socket

• 1 1/8" wrench or socket

• Thread locking compound - "Blue" Loctite 242 or equivalent

• Torque wrench (Not pictured)

• Penetrating lubricant – WD-40 or equivalent (Not pictured)

NOTE: The T-40 Torx is a security (aka “tamperproof”) bit that is needed to remove two bolts. This is

available from well-stocked hardware stores and online retailers like Amazon. It is also available

from US Hitch dealers.

NOTE: Thread locking compound is critical to the safe use of any hitch you install. Please use Loctite

242 "Blue" or its equivalent on all bolts that are not equipped with self-locking Nylock nuts.

NOTE: Elevating your trike will make installation easier. Always follow the manufacturer’s

recommendation for properly raising and securing your trike.

To begin installation, allows the exhaust system to cool down (if it has been running). When pipes are

cool to the touch, loosen the muffler clamp on each side of the trike.

Apply penetrating lubricant to the muffler slip-on point and allow it to work for a few minutes.

Twist the muffler from side to side until it moves freely. You do NOT need to remove the mufflers for this

installation. You only need to move them to the side to gain clear access to the bolts you will remove in the

next step.

Remove the tamperproof T-40 bolts found near the rear exhaust brackets on each side of the trike.

Remove the washers from these bolts to use during installation.

Install one of the saved washers on a 5/16-18 Grade 8 bolt and apply threadlock. Hold the baseplate up to

the trike frame and align the baseplate with the mounting points created when you removed the Torx

head bolts. Install the bolt far enough to securely hold the baseplate in place (about half way), but do not

tighten it fully.

Repeat this process for the other side. Tighten the bolts enough to raise the baseplate until it is near level,

but again, do not fully tighten these bolts. You’ll want to be able to reposition the baseplate as you install

the front bolts.

Place a supplied 3/8”-16 flat nut over one of the holes on the front horizontal frame member. You can

most easily reach over the top from the front of the frame member, then move/hold the nut over one of

the mounting holes.

Install a 3/8” washer on a 3/8”-16 Grade 8 bolt and apply threadlock. Insert and hand tighten the 3/8”-16

bolt. Repeat this process for the other side, then tighten all four bolts. If you have a torque wrench available

(recommended), torque the 5/16” bolts to 18 ft. lbs. Torque the 3/8”bolts to 33 ft. lbs.

This completes the installation of the baseplate.

Apply threadlock to the ½”-13 Grade 8 flange head bolts and install the tow bar. Tighten these bolts to 80

ft. lbs.

Apply threadlock to the bolt for the hitch ball. Install the bolt and lock washer. Tighten to 160 ft. lbs.
