March Recalls

The Bendix recall (NHTSA 12E-001) for the ATR-6 traction relay valve as reported earlier is still making the news. This is Bendix’s recall, in addition to the various truck builders’ recalls. In this one the now say they have a temporary fix, pending a permanent repair being developed.

 Later information from other more recent publications indicates that they have since developed a permanent repair and are making efforts to get them into the field. This notice says, "Bendix will notify owners who purchased the affected ATR-6 traction relay valves as aftermarket parts.

I’m sure Bendix will make every effort to notify owners, but as I always like to say, if you bought one at a parts counter, there’s a chance that Bendix will have no way of knowing that you have it. If you did so, or if you had one installed at an independent repair shop, I highly recommend that you go back to that parts house or repair shop. Let them trace it out and take appropriate action if need be.

 Most or all truck builders who were holding up shipments of trucks have gotten theirs and are now shipping again.

Paccar (Kenworth and Peterbilt) have issued their own recall (12V-026) for vehicles that were shipped with the affected valves. They show a total of 15,932 trucks involved in their recall.

Ford is recalling (12V-009) certain 2011 F-650 trucks manufactured between 2/2/2012 and 2/17 2011, and equipped with a Meritor MFS08 front steer axle.

 The bolts attaching the steering arm to the steering knuckle were not properly tightened. This condition can result in the steering arm loosening or separating.

Ford will notify owners, and dealers will inspect and repair the vehicles as necessary. Owners may contact the Ford Motor Co. Customer Relationship Center at 866 436 7332. Ford’s campaign number is 11S26. A total of 36 vehicles may be involved.

I don’t know how many MRs are in the fire service. I’m sure there are some. I doubt if there are many, if any LEs being used as fire trucks.

KME is recalling (12V-027) certain 2003 through 2011 AerialCats equipped with a bucket that is operated with electronic controls and a turntable that is equipped with hydraulic controls. On these vehicles, upon activation of the dead man’s switch on the turntable, the ladder may unexpectedly move. If the ladder unexpectedly moves, the operator may lose control of the bucket location.

KME will notify owners and dealers will repair the trucks free of charge. Owners may contact KME at 570 669 5154.

This is my own thought on the subject. I know of at least one, and there may be other earlier similar AerialCats that have gone back to KME for maintenance and/or repairs. I have to wonder if, in the process of doing repairs, KME may have upgraded controls to later standards, bringing them into the recalled range. This is just a guess on my part. I have no way of knowing this as I don’t know what KME does when vehicles come back into their facility for work. But it might be worth the price of a phone call.

HME has a recall (12V-033) out for a total of two 2011 1871 fire trucks with Cummins engines. This recall is for the same V-band clamps as reported last October (Cummins, Pierce) and November (Daimler, KME). HME is working with Cummins to identify the owners. Cummins is handling the notification and remedy. Owners may contact Cummins at 812 377 5000. Their campaign number is C1154.

 That's it for this month.  Even though this winter has been truly mild where I am, Spring is always welcome. I’m ready for it! …. Sam

    MRs aren’t common, but they’re not rare either.  I know of engines, rescues, and aerials all built on MR chassis.

    Not sure if all I knew of in person are still in service.  The late 80s was probably the heyday for their use as fire apparatus, so many are now aging out after 20+ years.
