4'6" X 7' SINGLE AXLE TRAILER: FINISHING

Fit your chosen coupler to the trailer using 3/8" UNF bolts and lock nuts or larger if required.

Bolts should only protrude through one side wall of the tongue section. Full width thru bolts should not be used and they may compress the box section and the coupler will not be securely fixed. It may be a bit of a squeeze getting the nuts from within the tongue section and a bit of grease on your spanner may help hold the nut in place while you turn the bolt.

Check that the coupler is centrally aligned before tightening up securely.

Fit the chain and hooks to the tongue using a chain washer and high tensile bolt.

Fit a plug holder if required on the tongue to keep the plug out of harms way while the trailer is in storage.

Fit the drop locks to the front and rear trailer uprights and bolt up securely and fit the tailgates.

Double check your spring hanger bolts and "U" bolts on the axle that they are secure and tight and the wheels to the trailer.

Hand tighten the stud nuts to help align the rim on the hub and tighten the nuts in sequence as below. Ideally use a torque wrench to ensure that the nuts are tightened adequately.

Torque Settings for wheel nuts are

7/16" UNF 110Nm or 80 Ftlbs

1/2" UNF 125Nm or 90 Ftlbs

Check with your local DMV for details on the paperwork required to legally get your trailer on the road.

After the trailers first decent trip or within the first 500 miles, recheck all coupler, spring and axle bolts for tightness. Recheck the wheel stud nut torque settings.
