The Garrett 740659-0008 is the rebuild kit for the wastegated GTP38 on a 1999.5–2003 7.3 Powerstroke. It is not the kit for the early TP38. Those trucks have no wastegate, and this kit will not fit them.

The kit is the rotating and sealing hardware for a stock GTP38 center section: journal bearing, thrust bearing, thrust collar, spacer, turbine and compressor piston rings, the backplate seal, and the housing bolts. Wheels, housings, and the wastegate actuator are not included. Use it when the turbo is oily, the shaft has play, or the housing is already off for a compressor-wheel swap. The pedestal O-rings and the compressor-housing O-ring are still worth replacing at the same time. Those are separate parts.

It fits late-1999.5 through 2003 Super Duty and Excursion 7.3 trucks with the GTP38. Build date after December 7, 1998. Early 1999 and OBS trucks need the TP38 kit.

• F-250, F-350, F-450, F-550, and Excursion

A rebuilt center section will still leak oil if the pedestal rings are reused. Order PEDSKIT94-03 with it.
