September Recalls

Bendix Commercial Vehicle Systems is recalling (NHTSA Recall #12E020) certain brake valves, treadle assemblies and/or plunger kits sold as aftermarket replacement equipment, and sold and installed as original equipment to various vehicle manufacturers.

The brake valve plunger may fracture during brake application, resulting in reduced brake pedal angle and travel. This condition may limit the driver’s ability to deliver full pressure from the foot brake valve. There is also a potential that the brake plunger could become lodged and not allow release of the service brakes.

Bendix will notify owners of the aftermarket equipment and will provide a free remedy. Bendix is working with vehicle manufacturers to identify and repair the vehicles that contain the subject brake valves, treadle assemblies and plunger kits, free of charge.

The safety recall began in June. Owners may contact their vehicle manufacturer or Bendix at 440 329 9386.

And let me add my usual word of caution when I see a part or component being sold as aftermarket replacement: When a component manufacturer puts a part into the supply chain, it may pass through several hands before it reaches the end user (YOU). At any one of those changes of hands, there’s the possibility of the manufacturer or the last guy in line losing track of where it finally went. So you need to be aware of what you have purchased or had installed on your vehicle. If you have had a such a part replaced, you need to make it your business to try to identify it and get with whoever sold it to you to find out if it is or is not one of the ones that has been recalled.

Dorman Products is recalling (12E-021) certain service replacement equipment control arms, part numbers 520-121, 520-122, 2410121 and 2410122, shipped from November 2010 through January 2012.

The control arms may have inadequate heat treatment of the ball stud, possibly resulting in a premature fracture. Fracture of the ball stud on the control arm can result in impaired steering.

Dorman will notify owners and refund all amounts paid and/or replace recalled units at no cost to the owner. The safety recall began on June 13. Owners may contact Dorman at 800 523 2492.

And again, the caution above applies.

Kovatch Mobile Equipment (KME) is recalling (12V253) certain 2010 Predator, Predator SS, Predator Panther and Predator XL vehicles equipped with feature code 04AZX Meritor Wabco Electronic Stability Control (ESC) units. Under certain road and driving conditions, vehicle body roll and road inclination characteristics may adversely affect the slip angle calculation of the ESC system. This might cause the ESC to perceive an oversteeing condition and therefore apply the outer wheel brake on the front axle until the vehicle is perceived to be stable.

Consequence: The vehicle may deviate from the intended line of travel, increasing the risk of a crash.

KME will notify owners, and dealers will install a new ESC module free of charge. The recall began on June 5. Owners may contact KME at 570 669 5154. KME’s recall number is L-02.

Daimler Trucks North America is recalling (12V266) some 2013 Frieghtliner , Western Star and Freightliner Custom Chassis trucks equipped with Detroit Axle front axle knuckles.

The front knuckles on these vehicles may have a machining error in the front wheel bearing area that may lead to a premature spindle failure.

DTNA will notify owners, and dealers will inspect and replace the affected components free of charge. The recall began on or before August 11, 2012. Owners may contact DTNA at 800 547 0712. DTNA’s recall number is FL-629.

Spartan is recalling (12V279) some 2010 – 2012 Gladiator chassis equipped with a Cummins ISX 15L engine and fan clutch assembly.

Fasteners used to mount the fan clutch mounting bracket to the front of the engine may shear, resulting in the cooling fan, fan clutch, and mounting bracket separating from the engine. If this occurs and the cab is in the raised position, the separation could increase the risk of personal injury.

Spartan Chassis will notify owners, and repair the vehicles. The recall was to have begun about July 13. Owners may contact Spartan at 800 543 5008. Spartan’s recall number is 12007.

As predicted some months ago, Pierce is issuing its own recall (12V-311) of certain vehicles manufactured with Detroit Diesel DD13 EPA07 and EPA10 engines. In Pierce’s case, the engines were installed as original equipment on some Arrow XT, Contender Big Block, Dash CF, Quantum and Velocity chassis. The pump to rail high pressure fuel line support system used on these engines is sensitive to assembly torque and may be damaged during service work. As a result of other repairs, the line supports may loosen, potentially leading to fuel line cracking and a fuel leak.

Pierce will notify owners, and the high pressure fuel line support will be replaced by Daimler Trucks North America authorized service facilities, free of charge. The safety recall is expected to begin during March, 2012. Owners may contact DTNA at 800 547 0212 or Pierce at 920 832 3000. Pierce’s recall number is 74B233.

That's all for now.  Enjoy this warm weather while it lasts.  Sam.

    I like Spartan! It is very effective and durable. But KME is also good though.
