1. Apply a light coating of grease to the entire outside of the stub axles and fully insert
the axles into the trailer bed axle tube. noTe: The stub axles for each side of your
trailer are different! The stub axle marked ‘D’ goes into the right side of the trailer
bed (bicycle drive side) and the stub axle marked ‘ND’ goes into the left side of the
trailer bed (bicycle non-drive side). During installation, rotate the stub axles so that
the wedges are orientated in the 6 o’clock position. Finally, tighten the wedge bolts
(torque = 20 Nm) to hold the stub axles in the trailer bed.
2. To install the wheels, slide an axle washer onto the stub axle followed by a wheel
and then secure the assembly with the proper wheel retaining bolt (torque = 30 Nm).
NOTE: The wheel retaining bolts for each side of your trailer are different!
The drive side bolt has left-hand threads and the non-drive side has right-hand
threads. Markings on the bolt head will tell you which bolt to use on which side
of the trailer.
3. Install the (14) M5 x 16mm socket head cap screws into the bosses located on the
curved wheel cover tube and snug tight (torque max = 7 Nm). The fasteners are
included for mounting fenders and spoke guards to your trailer. Make your own or
visit surlybikes.com to see what we offer.
4. Thread the (8) M6 x 25mm machine screws (2 per clamp) into the clamps of the
wheel covers. Slide the wheel covers on to the wheel cover stubs with the spoke
guard bosses facing inboard toward the trailer bed. Ensure that the wheel cover is
positioned flush against the trailer bed and tighten clamp hardware (torque = 8 Nm).
Install the deflector shields by using the (4) M6 x 20mm flat-head machine screws
(torque = 6 Nm).
5. Install reflectors on the rear wheel cover stubs on the outside of the wheel
cover clamps.
6. Thread the (4) M6 x 20mm machine screws into the boom clamp at the front
of the trailer bed. Do not tighten yet.
7. Install one spring onto each hitch thumbscrew and thread thumbscrews
into the hitch hooks.
8. Slide the non-drive side yoke into the clamp of the drive side yoke and install the
(2) M6 x 20mm machine screws into the clamp. You’ll adjust the hitch width later.
9. Attach the boom to the yoke with the appropriate hardware through the hammer
joint. NOTE: The washers are serrated on one side only and must be installed
correctly! The smooth side of each washer should face the brass, the rough side
toward the paint. You’ll adjust the tightness of both pivots later. Be sure to thoroughly
grease all friction surfaces in the joint! Grease is the word.
