5.3 TIRE CARE
I
mproper inflation will shorten the life of your tires and will adversely affect performance. For proper tire
inflation refer to Section 1.5 recommendations.
NOTICE:
Replacement tires must be the same size as original equipment. Increased tire load
ratings are permissible but tire rating does not increase the rated load carrying capacity of the
vehicle.
5.4 WHEEL & TIRE REMOVAL/INSTALLATION
Place blocks ahead of and behind the wheels that will remain on ground. Slightly loosen lug nuts. Place
jack under one side of vehicle on frame rail at point midway from front and back of vehicle. Raise vehicle
and remove lug nuts and wheels. To install, tighten the lug nuts evenly in a star pattern until the nuts are
all seated and torque to. 65 ft. lbs. (88.1 N.m). Recheck lug nut torque with the vehicle on the ground.
NOTICE:
The wheel may be bent if not torqued in a crossing pattern. This will cause the wheel
to wobble.
5.5 CLEANING
Wash underside to remove all dirt and debris. Do not direct high pressure water at the controller, speed
switches, or tops of the batteries.
Wash body and seat with a mild detergent. Do not use abrasives (bodies are painted). Frequent washings
with mild soap will preserve the finish of your vehicle. For stubborn and imbedded dirt, a soft bristle brush
may be used. Tar, asphalt, creosote and the like should be removed immediately to prevent staining of
paint.
5.6 LUBRICATION
For three wheel vehicles, semi-annually grease the single front hub assembly (Figure 5.6.1). For four
wheel vehicles, semi-annually grease the two steering arm spindles (Figure 5.6.2). Use a high quality
wheel bearing grease. Remove the weight from the front suspension before lubricating to ensure proper
grease distribution.
The differential should be checked periodically for signs of leakage. Contact your Columbia Dealer for
fluid replacement.
