All 142 / 144 / 145 problems All workshop issues

Common Transmission and Drivetrain

Worn Clutch (Manual Transmission)

Symptoms

Slipping under load (engine revs rise without acceleration), high biting point, difficulty engaging gears, juddering on takeoff, burning smell.

Cause

Friction material wears thin, pressure plate weakens, oil contamination from a leaking rear main seal.

Fix

Gearbox-out job.

Fit a new clutch kit (plate, cover, release bearing).

Inspect the flywheel for cracks or hot spots, have it skimmed if scored.

Replace the spigot bearing while you're in there.

If the rear main seal is leaking, fix it now, oil on the clutch will destroy it within weeks.

Bleed the hydraulic system and adjust the pedal freeplay to spec.
