Wheel ends
Two types of lubrication are used in wheel ends:
oil or semi-fluid grease. If oil is used, check the oil
level in all hubs before every trip. Add oil when low,
but only to the level indicated by the mark on the
hubcap face. Too much oil may cause leaks.
Semi-fluid grease will be indicated by a label on
the wheel end or trailer. There will be no oil level
viewing window in the hubcap. Even though there
is no way to visually check the lubrication level, you
must still inspect the wheel ends before every trip to
ensure that there are no lubrication leaks. Grease
around the inner hub seal or grease contamination
on the inside of a wheel and tire indicates a
possible leak and requires immediate service.
Wabash National recommends compliance with
TMC Recommended Practice No. 631A with
respect to wheel-end-lubrication inspection,
maintenance, and service. This Recommended
Practice states that a hub should be filled with
semi-fluid grease to the 3 o’clock-and-9 o’clock
level (cavity filled 50% full).
WaRNING:
follow the guidelines below to avoid potentially
hazardous situations that may result in death or
serious injury.
• Never mix oil and semi-fluid grease in the same
wheel end.
• Always use the same type of oil or semi-fluid
grease in the same wheel end.
• Consult your local lubricant supplier for product
recommendations.
Doors
Lubricate the door counterbalance, bearings,
rollers, hinges, and locking handle regularly with
a dry spray lubricant according to manufacturer’s
recommendations. When lubricating, wipe dirt
residue and buildup from the roller tracks. Do not
use any petroleum-based lubricant on the rubber
door seals. Additional operation and maintenance
information for your specific door system can be
reviewed at the appropriate web sites accessible
through www.wabashnational.com.
CAUTION:
The frequency of door maintenance will vary
with climate conditions and use.
