GM J-44641 Duramax 6.6L Rear Crankshaft Seal and Wear Sleeve Remover Puller (Alt. ST-195)

General Motors Tool Number: GM-44641

Application: 2001 and later GMT800, 2500HD, 3500 models with a 6.6-liter Duramax diesel engine.

Description: The rear crankshaft seal on these models is press-fitted to both the engine block and crankshaft. Traditional methods of prying seals from the block can damage both. The GM J-44641 is a specialized puller designed to safely remove the rear crankshaft seal without causing damage.

Features:

  • Three-Jaw Design: The puller features three jaws that securely grip the inner lip of the seal.
  • Forcing Screw Mechanism: The forcing screw, attached to the center plate, reacts against the crankshaft end to pull the seal out smoothly and efficiently.

This tool ensures a safe and effective removal process, preserving the integrity of the engine components.
