Tales from the Workshop
Unusual tips and fixes.
Hydraulic clutch operation has one big advantage over its cable counterpart, which is that it adjusts itself as the clutch centre plate wears, saving the need to constantly adjust the clutch to accommodate for wear. The downside of this is that often the driver will be unaware that the clutch is wearing and the clutch plate will eventually get to the point where the lining is too thin to support drive and will fail.
That’s precisely what happened to the owner of this 1997 Volvo 940. He had owned the car for many years and had never fitted a new clutch. It’s possible that the clutch feel had changed over time, but the change went unnoticed until he was pulling away at a junction and the car refused to move.
The inline set-up of the Volvo makes the gearbox easy to remove, and once the clutch was unbolted we could see that the lining had gone completely from one side of the drive plate.
The clutch drive plate had lost all of its lining.
