1994 INTERNATIONAL HARVESTER 4900 Recall

Campaign:

94V144000 on 08/16/1994

Component:

Engine and engine cooling:engine:gasoline:turbo-charger

Manufactured:

12/31/1993 - 02/28/1994

Affected:

373

Defect:

Four compression backplate retaining fasteners on the turbo-charger were torqued only hand tight. this allows the fasteners to loosen, and causes oil to leak into the compressor air side of the turbo-charger which, when coupled with the heat precipitated by the compressor and the mixing action of the compressor wheel, can result in an air/oil mixture that fuels the engine.

Consequence:

When this occurs, engine run-on and subsequent loss of operator control via the normal throttle mechanism can occur, which could result in a vehicle accident.

Correction:

Replace the suspect turbo-charger with a new turbo-charger.
