Summary: The air compressor air supply line is routed from the compressor over the top of the frame rail, under the brake hydromax, and down to the air system. This line can contact the steel section of the hydromax hydraulic supply line, causing a leak to occur in the hydraulic line, allowing hydraulic fluid to leak on the left front wheel and brake assembly.
Consequence: The leak allows enough fluid to be pumped from the system to eliminate power steering assist. The electronic secondary brake pump will engage, but the leak will result in increased stopping distance.
Remedy: Dealers will install a cushion clip on the top left frame rail separating and eliminating any contact between the steel jacketed air line and the metal section of the hydraulic line.
Notes: System: brakes; air system.vehicle description: truck chassis.note: if your vehicle is presented to an authorized dealer on an agreed upon service date and the remedy is not provided within a reasonable time and free of charge or the remedy does not correct the defect or noncompliance, please contact oshkosh service at 1-414-235-1726.

Has your Oshkosh been repaired?

Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.

Check your VIN with NHTSA

NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Oshkosh dealer can also check your VIN. Recall repairs are free.
