Luk DMF191 Clutch Flywheel

LuK DMF191 Dual Mass Flywheel Overview

The LuK DMF191 is a dual mass flywheel engineered for specific Volkswagen applications, including Golf, Golf SportWagen, Beetle, Jetta, and Passat models. Built to OE-style specifications, it is tuned to reduce drivetrain stress and maintain smoother clutch operation compared with a solid flywheel setup.

Key Features

• Dual mass flywheel design for drivetrain damping and smoother engagement
• Flywheel diameter: 22.7 in. / 8.937 in.
• Flywheel inner diameter: 15.5 in. / 6.102 in.
• Flywheel cup depth/step height: -0.593 in. / -15.05 mm
• 129-tooth ring gear for proper starter engagement
• OE-matched fitment for select Volkswagen manual transmission applications

Detailed Description

LuK DMF191 is a clutch flywheel built around the dual mass flywheel concept used on many late-model Volkswagen platforms. The design helps isolate engine vibration from the transmission, which is important for preserving clutch feel and reducing stress on related drivetrain components. This part number, DMF191, is specified for 2014-2019 Volkswagen applications and is a direct-fit option for drivers replacing a worn OE flywheel on a Golf, Golf SportWagen, Beetle, Jetta, or Passat.

LuK notes that its DMF design is individually tuned by vehicle application, which matters because flywheel mass, step height, and tooth count must align with the original drivetrain setup. The DMF191 cross-references 06J105266AK, 4150726100, and NDMF191 for the same application.

What This Flywheel Helps Address

• Clutch chatter or rough engagement during takeoff
• Excess drivetrain vibration transferred into the cabin
• Premature wear on engine mounts from torsional shock
• Gearbox stress caused by inconsistent flywheel damping
• Crankshaft loading associated with worn or incorrect flywheel design

Installation Notes and Tips

Confirm the flywheel diameter, inner diameter, step height, and 129-tooth count against the original part before installation. This LuK DMF191 is used on select Volkswagen Golf and Jetta platforms, so matching the exact year and model is important for proper starter and clutch alignment. Inspect the clutch assembly, release components, and rear main seal during service to avoid repeat labor.
