Naturally aspirated

7. Measure clutch plate thickness, renew plate if less than service limit.

Naturally aspirated

Clutch plate thickness – new clutch plate = 6.9 – 7.4 mm

Clutch plate thickness – service limit = 5.6 mm

Turbo

Clutch plate thickness – new clutch plate = 7.1 – 7.5 mm

Clutch plate thickness – service limit = 5.8 mm

8. Measure rivet depth, renew plate if less than service limit.

Rivet depth – new clutch plate = 1.0 mm

Rivet depth – service limit = 0.2 mm

9. Measure clutch plate run – out using a dial gauge and a gearbox mainshaft; renew plate if outside service limit.

Run – out – new clutch plate = 0.8 mm

Run – out – service limit = 1.0 mm

10. Check clutch plate for signs of wear or damage. Check for signs of overheating on drive straps (deep straw to blue colour); renew pressure plate if necessary.

CAUTION: Renew a pressure plate which has been accidentally dropped.

11. Using a straight edge and feeler gauges, check surface of pressure plate for warping at 4 separate points, renew plate if warping exceeds service limited.

Naturally aspirated

Pressure plate warping – service limit = 0.15 mm

Turbo

Pressure plate warping – service limit = 0.18 mm

Release bearing

12. Remove bolt securing release fork to shaft, withdraw shaft; recover fork.
13. Release spring securing release bearing, remove bearing.
14. Remove shaft oil seal from differential housing; discard seal.
15. Examine release bearing for signs of wear or damage, renew if necessary.
