OE-Style Fitment and Construction

Built as a clutch flywheel for manual transmission service, the LuK LFW137 provides the flat, stable surface needed for proper clutch operation. Its 24.8-inch flywheel diameter, 14.43-inch inner diameter, and 132-tooth ring gear are matched to the listed applications, making it a practical replacement when servicing a Ford Ranger or Mazda B2300/B2500 clutch system. This part cross-references Sachs NFW1145 for the same application.

Compatible with 1995-2001 Ford Ranger and 1995-1997 Mazda B2300, plus 1998-2001 Mazda B2500. The LuK LFW137 is a direct replacement choice when the original flywheel is worn, heat-checked, or no longer provides the correct clutch contact surface.

Common Problems This Flywheel Can Address

• Clutch chatter caused by an uneven flywheel surface
• Judder or vibration during takeoff
• Heat spots, scoring, or glazing on the friction face
• Starter engagement issues related to ring gear wear
• Clutch replacement jobs that require a fresh flywheel surface

Installation Notes and Tips

Inspect the clutch, release components, and crankshaft sealing area before installation. For 1995-2001 Ford Ranger and 1995-2001 Mazda B2300/B2500 applications, refer to LB194 regarding slave cylinder release bearing compatibility. Verify tooth count, diameter, and OE-style fitment before assembly, and follow the vehicle manufacturer’s torque and service procedures.

Quality Assurance

LuK manufactures this flywheel to OE specifications, including the ring gear and dowel pins, to support accurate fit and consistent clutch operation. Because it is supplied as a new component, it avoids the variability associated with resurfacing an existing flywheel.
