Recall 99V042000 · manufacturer campaign SPEC 99001

What's wrong

VEHICLE DESCRIPTION: TRANSIT BUSES. DUE TO THE ROUTING OF THE HIGH PRESSURE HYDRAULIC HOSE CONNECTING THE DISTRIBUTION MANIFOLD TO THE COOLING FAN, HYDRAULIC MOTOR OR THE HIGHER OPERATIONAL SPEED OF CNG ENGINES COULD, IN CERTAIN CIRCUMSTANCES, PUSH THE PRESSURE DEVELOPED BY THE HYDRAULIC PUMP BEYOND THE NOMINAL WORKING PRESSURE OF THE INSTALLED HOSE. THERE IS THE POSSIBILITY OF STRESSING THE HOSE BEYOND ITS MINIMUM BEND RADIUS AND/OR BEYOND ITS NOMINAL WORKING TEMPERATURE/PRESSURE RATINGS.

The risk

A HOSE FAILURE COULD OCCUR ALLOWING HYDRAULIC FLUID STEAM TO IMPINGE ONTO HOT EXHAUST COMPONENTS AND INITIATE AN ENGINE COMPARTMENT FIRE.

The fix

SPARTAN IS DEVELOPING A FIELD RETROFIT KIT WHICH WILL CONSIST OF A NEW HYDRAULIC FLUID HOSE THAT WILL BE 3 INCHES LONGER THAN THE ORIGINAL AND HAVE A HIGHER WORKING PRESSURE RATING; A 45 DEGREE HOSE CONNECTION FITTING WILL BE ADDED AT THE FAN MOTOR INLET PORT; THE HOSE WILL BE RE-ROUTED AND ALSO CLIPPED OR CLAMPED; AND THE MANIFOLD BLOCK/PRIORITY VALVE WILL BE RELOCATED.

ALL VEHICLES IN INVENTORY AT MANUFACTURERS.NO OWNERS INVOLVED.
