MAINTENANCE PROCEDURES
This section includes instructions for basic maintenance procedures. If you have the necessary mechanical skills and the required tools, you can perform these procedures. If not, see your authorized Can-Am Roadster dealer.
Tire Inspection
Replace the tire before towing the trailer if the tire tread has less than
1.6 mm (1/16 in) depth or if the built-in wear indicator bars are visible and flush with the remainder of the tire tread.
Inspect both sidewalls of each tire for any bubble, cut or bulge; and replace a damaged tire before towing the trailer.
WARNING
Torque wrench tightening specifications must be strictly adhered to.
Locking devices (e.g.: locking tabs, elastic stop nuts, cotter pins, etc.) must be replaced.
WARNING
A bubble, cut or bulge in the sidewall can result in a tire blowout and loss of control which can lead to serious injury or death.
Hoses, cables or locking ties removed during a procedure must be reinstalled as per factory standards.
Wheels
Coupler
Coupler Inspection
Check tightness of coupler bolts. If bolts are loose, check coupler and tongue for damage. Retighten bolts to the specified torque.
Wheel Inspection
Check wheel for cracks, bumps or other damages. Replace wheel as required.
Wheel Bearings
TIGHTENING TORQUE
Coupler bolts
48 N•m ± 6 N•m
(35 lbf•ft ± 4 lbf•ft)
Wheel Bearing Inspection
Install a jack under trailer frame.
NOTICE Make sure to place the jack under frame and not under trailer shell. Severe damages will occur if the trailer is raised by its shell.
Check locking mechanism operation.
Lubricate and adjust as required.
Tires
Tire Pressure
Check tires pressure. Tire pressure must be checked while the tire is cold.
NOTE: Do not check the tire pressure immediately after towing the trailer.
Allow at least three hours for a tire to cool, if the trailer has been towed for as much as 1.6 km (1 mi).
Cold tire
Push and pull the wheel from the upper edge to feel the play.
If any play is felt, replace wheel hub bearings. See
MENT
.
BEARING REPLACE-
Check if the wheel turns freely. If wheel is hard to turn, lubricate or replace wheel bearings.
TIRE PRESSURE
241 kPa (35 PSI)
Wheel Bearing Lubrication
1. Remove wheel hub, refer to
WHEEL HUB REMOVAL
.
2. Clean the deteriorated grease from the bearings and the hub internal.

3. Check seal condition. Replace it if necessary.
4. Fill the bearings with hi-temp bearing grease NLGI-2 or an equivalent.
NOTICE Do not fill up more than
20% of the cave between the bearings.
5. Install wheel hub as explained in
WHEEL HUB INSTALLATION
.
NOTICE Strictly adhere to the installation procedure.
6. Install wheel and tighten lug nuts to the specified torque in a crisscross sequence.
TIGHTENING TORQUE
Wheel lug nuts
105 N•m ± 15 N•m
(77 lbf•ft ± 11 lbf•ft)
Wheel Hub Removal
NOTE: Bearings are not available as spare parts. When bearing replacement is required, replace wheel hub as an assembly.
1. Install a jack under trailer frame.
NOTICE Make sure to place the jack under frame and not under trailer shell. Severe damage will occur if the trailer is raised by its shell.
2. Remove the wheel.
3. Remove the protective cap.
4. Remove and discard the cotter pin.
5. Remove the wheel hub nut and washer.

Wheel Hub Installation
1. Fill the bearings with the hi-temp bearing grease NLGI-2 or an equivalent.
NOTICE Do not fill up more than
20% of the cave between the bearings.
2. Place hub on the spindle and secure it loosely using the hub nut and its washer.
Adjust the bearing preload as follows:
1. Seat bearings by tightening hub nut while turning the hub.
TIGHTENING TORQUE
(FOR BEARING SEATING ONLY)
Wheel hub nut
17 N•m ± 2 N•m
(150 lbf• in ± 18 lbf• in )
NOTICE This is a preliminary tightening to seat the bearings only.
