Detailed Description

The LuK LFW142 is a clutch flywheel for manual transmission repair where the flywheel surface condition is critical to clutch performance. Its OE-style dimensions and 132-tooth ring gear support proper starter engagement and clutch operation. This part number is a smart replacement choice when resurfacing is not preferred or when the existing flywheel is worn, heat-checked, or uneven. LuK LFW142 is used in service for 1983-1994 Ford Ranger, 1994 Mazda B2300, 1983-1988 Ford Thunderbird, 1986-1987 Ford Aerostar, 1984-1986 Mercury Cougar, and 1983-1984 Mercury Capri applications.

This part cross-references Sachs NFW1101 for the same application.
