The high pressure hose is constructed with reusable or crimp ends. The hydraulic motor is located at the rear of the bus, inside the engine compartment. The end of the hose that is connected to the fan motor has disconnected from the hose connector.

Remedy

Dealers will replace the hydraulic hose assembly. Owner notification began april 1, 2003. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact orion at 1‑905‑403‑1111.

Recall number 03V063000 · Recall details

What is wrong

Vehicle description: transit buses equipped with vanner 60 series battery equalizers. The equalizer could fail to operate properly and cause malfunction of the battery charging system.

Risk

Without fusing, the equalizer may melt, burn, or smoke, possibly resulting in a fire or a smoke filled bus, thus necessitating a passenger evacuation of the bus. The failure mode can cause operator distraction, and/or possible personal injury.

Remedy

Recall number 98V331000 · Recall details

What is wrong

Vehicle description: transit buses equipped with wheel chair barriers. The wheel chair barriers are attached to the floor structure with a bolt threaded into the floor structure. In the case of a frontal crash, with the wheel chair position occupied, the bolt threads could strip allowing movement of the wheel chair barrier.

Risk

This condition could allow movement of the wheel chair which could cause personal injury, or death, to the wheel chair occupant.

Remedy

Recall number 98V210000 · Recall details

What is wrong

Vehicle description: transit buses equipped with sunsource/fauver tandem hydraulic pumps. The hydraulic piston pump is driven by the engine and a shaft out of the back of the pump providing power to the power steering pump. The shafts are connected together with a coupling. This coupling is fitted with two retainer clips which keeps it centered between the two pumps. These buses were shipped missing the coupling retainer clips.

Risk
