2000 New Flyer D60HF problems

What is wrong

New flyer is recalling 431 my 1996-2001 d60hf diesel transit buses equipped with a rooftop air conditioning evaporator. The evaporator drain lines make contact with components (ballast assemblies) within the interior lighting panel below the drain line port. This can result in either damage to the drain line, which introduces moisture into the lighting panel, or restriction of the line which results in a back-up and overflow of moisture through the fresh air return vent and back into the lighting panel.

Risk

Moisture in sufficient quantities within the lighting panel may result in a shorting of the electrical components and a vehicle fire.

Remedy

New flyer will incorporate an elbow fitting into the drain line where it enters the lighting panel from the roof, which will promote clearance between the line and the ballast assembly. The recall began on february 6, 2008. Owners may contact new flyer at 1‑204‑934‑4803.

Recall number 08V053000 · Recall details

What is wrong

On certain transit buses, the u-joint assemblies have inadequate spline engagement on one of the two end yokes.

Risk

Excessive play in the steering system could develop and, if not corrected, cause a loss of steering control which could result in a crash.

Remedy

The u-joint assembly will be inspected and replaced if necessary. The recall began on june 10, 2007. Owners may contact new flyer at 1‑204‑934‑4874.

Recall number 07V268000 · Recall details

What is wrong

On certain transit buses, the center axle wheel end brakes may not release after being parked for an extended period of time.

Risk

The driver could lose control of the vehicle when driving away from a parked position, which could result in a crash.

Remedy

New flyer will install an additional air system r14 relay valve, #4 notch automatic slack adjusters, and type 30 long stoke brake chambers on the center axle; the logic control module will be reprogrammed, add new ABS components (sensors, speed rings and harnesses) if not already equipped with ABS; and will revise plc programming. Owners may contact new flyer at 1‑204‑982‑8400.

Recall number 04V042000 · Recall details

What is wrong

Certain transit buses fail to comply with the requirements of federal motor vehicle safety standard no. 121, "air brake systems." the service brake release timing and park brake apply timing are out of compliance with the standard.

Risk

These vehicles do not comply with federal standards.

Remedy

To resolve the issue of noncompliance with the service brake release timing, dealers will re-route the redundant signal line to the center axle relay valve and the center and rear relay valves will be swapped. Owner notification began july 17, 2003. Owners should contact new flyer at 1‑204‑982‑8400.

Recall number 03V248000 · Recall details

The office of defects investigation opened this preliminary evaluationbased on a fleet report of 3 thermal events allegedlythe result of condensation from the air conditioner's evaporator drain hose shorting electrical connections and various electrical components. The investigation was opened to evaluate and determine the cause of these thermal events. A technical evaluationdetermined that the drain line for the rooftop evaporator unit contacted the ballast inverter for the fluorescent lighting panel and became abraded.the abrasion of the drain lineresulted in low pressure and low volumes of moisture being introduced into the lighting panel resulting in electrical shorts.new flyer decided to conduct a safety recall to correct the problem.the corrective action will be to install an elbow on the air conditioning drain line where it enters the bus interior.this elbow relocates the drain line to provide the needed clearance between the line and lighting components.this remedy resolves the issue under investigation and, therefore, this investigation is closed.

This investigation was prompted by a transit fleet, which informed odi in november, 2003, that they were experiencing brake problems on their high floor articulating style buses.in the letter, the fleet stated that they had experienced over 50 incidents where the rear brakes failed to release during morning pullout from their parking location.they alleged that there had been three crashes resulting in property damge as the result of this sticking brake phenomenon.the crashes originate when the middle axle brakes fail to release and the rear engine vehicle pushes the middle axle resulting in a jack-knife condition of the articulated bus. As a result of odi'sinvestigation, new flyer has agreed to initiate a safety recall and correct this condition on all affected buses.the action taken by new flyer is sufficient to resolve the issue raised by this investigation. A copy of the recallis attached.accordingly, this investigation is closed.
