JUNE 2010 --
Kenworth is recalling certain model year 2009 through 2010 T660 tractor trailors
manufactured from July 1, 2008 through July 31, 2009. The retaining pins
securing the hood strut lock tube to the hood strut assembly may become loose
and fall out allowing the lock tube to rotate on the strut assembly. In its
normal operation the safety latch feature is automatically set and it prevents
the hood from closing. With the hood closed and the retaining pins missing, the
lock tube may rotate relative to the good strut resulting in a non-operational
safety latch feature when the hood is opened. A non-operational safety latch
feature may not be detected by an operator increasing the risk of personal
injury and/or vehicle damage should the hood unexpectedly close. Dealers will
replace the pivot disc and lock tube retaining pins with a revised pivot disc
and cap screws. This service will be performed free of charge. The safety recall
is expected to begin during June 2010. Kenworth"s safety recall number is
10KWE. 10V-266
MAY
2010 --
Kenworth is recalling certain model year 2010 T2000, T660, T800 and W900
vehicles manufactured between July 30, 2009 and September 18, 2009. The rear
axle outer end hub may have not been primed with oil properly during the rear
axle installation process. Potential lack of oil may cause the outer end bearing
to heat up and/or seize, possibly resulting in the overheating of the wheel end.
A wheel end fire may occur, increasing the risk of a crash. Dealers will replace
the bearings, seals and will add oil to the outer end hub as well as inspect
races and axle housing for damage and replacing as necessary free of charge. The
safety recall is expected to begin during June 2010. 10V-185
MAY
2010 --
Kenworth is recalling certain model year 2011 T270, T370, and T800 trucks
manufactured from January 28 through March 19, 2010, equipped with DV-2 air
governor containing part number G90-1070- 2111111 on the T270/370 model trucks
and part number G90-1070-11113111 on the T800 model trucks. The DV-2 air
governor was misassembled with a blank plug instead of a breather. Without the
breather installed, the air governor may not be able to detect the loss of air
pressure in the air system during normal use. This condition may result in the
slow activation of the emergency spring brakes. Although the operator is warned
of low air pressure by audible and visual low air pressure warning alarms, a
vehicle crash or fire is possible if these warnings are not heeded. Kenworth
will notify owners and repair the vehicles by replacing the blank plug with a
breather and inspect for proper function free of charge. The safety recall is
expected to begin during June 2010. Kenworth's campaign number is
10KWD. 10V-211
MAY
2010 --
Kenworth is recalling certain model year 2009 through 2011 C500 trucks
manufactured from October 24, 2008 through January 13, 2010. During maneuvers
with certain combinations of wheel turn, articulation, and bump, the brake
chamber can contact the rear hood support. The contact can damage the brake
chamber leading to a loss of braking function at the affected wheel end,
increasing the risk of a crash. Kenworth will notify owners and dealers will
repair the vehicles free of charge. The safety recall is expected to begin
during June 2010. . Kenworth's recall number is 10KWC. 10V-212
APRIL 2010 --
Kenworth is recalling
certain model year 2010 T270
and T370 trucks equipped
with non-LMS hubs. The
spindle nut attaching the
hub and bearing to the axle
spindle (steer or drive) may
have been over-torqued
during the hub installation
process. An over-torque of
the spindle nut may cause
the bearing to seize,
possibly resulting in the
overheating of the wheel
end. As a result, a wheel
end fire may occur. Dealers
will replace the bearings
free of charge. The spindle
and hub will be inspected
for scoring and replaced if
necessary. The safety recall
is expected to begin during
May 2010.

SEPTEMBER 2009
-- PACCAR is recalling model
year 2008-2010 Kenworth
T300, T270, and T370, model
year 2009-2010 T800 and
Peterbilt model year
2008-2010 335, 340, and 367
vehicles built on Cummins"
diesel engine. The vehicles
may be designed with a hard
wired, dash-mounted switch
that enables the vehicle
operator to inhibit after
treatment diesel particulate
filter regeneration in
environments where the
operator believes it may be
unsafe for elevated exhaust
temperatures. Due to an
issue with the logic in the
ECM software in these
engines, the switch may not
function correctly, leading
the operator to believe that
the switch is in "inhibit"
mode when it is not. This
condition will permit hot
exhaust gases to exit the
vehicle tailpipe, increasing
the risk of melting or
burning of nearby surfaces,
or a fire. Paccar is working
with Cummins to repair the
engines free of charge
please see 09E-046. The
safety recall is expected to
begin during September 2009.
09V-348
JUNE
2009 -- Kenworth
is recalling 13 MY 2009
T2000 vehicles for failing
to comply with the
requirements of Federal
Motor Vehicle Safety
Standard No. 106, "Brake
Hoses." Air tube expander
fitting used between the air
tube inlet and dash air
gauges for the trailer does
not meet the burst pressure
requirements. This can
result in brake hose
rupture, air pressure loss,
and compromised vehicle
braking which could result
in a crash without warning.
Dealers will inspect and
replace the expander fitting
which is related to 1,200
PSI. This service will be
performed free of charge.
The manufacturer has not yet
provided an owner
notification schedule.
09V-227
JUNE 2009 --
Kenworth is recalling 9 MY
2009 T800S vehicles equipped
with Dana front axle. The
brake spider mounting
fasteners attaching the
brake spider to the front
steer axle flange may have
received insufficient torque
during the installation
process. The insufficient
torque may allow the brake
spider fasteners and brake
spider to become loose. This
can allow the fasteners to
shear and fall either onto
the roadway or into the drum
brake assembly, potentially
allowing the brake to bind
and causing increased
stopping distance and a
crash could occur. Dealers
will inspect and replace the
brake spider mounting
fasteners and torque them
properly, as well as review
the brake spider and steer
axle flange holes for signs
of vibration and fatigue and
replace if necessary. This
service will be performed
free of charge. The
manufacturer has not yet
provided an owner
notification schedule.
09V-229
JUNE
2009 -- Kenworth
is recalling 3,423 MY
2004-2009 T2000, T800, T600,
W900 and T660 vehicles.
Increased brake excitation
in a certain vehicle
configuration which includes
Bendix drum brakes, wide
base low profile single
tires, and an AG400 or AG460
rear suspension, can cause
fatigue and cracking of
brake assembly components.
Cracking can cause a
complete fracture of the cam
tube, which could increase
stopping distance and
decrease parking brake hold
capability. Dealers will
inspect the rear axle brakes
assembly, replace cracked
rear axle brakes assembly
components where required,
and install cam tube support
brackets on all rear axle
wheel ends free of charge.
The recall is expected to
begin or before July 25,
2009. 09V-239 |
