Exhaust camshaft front oil seal (page 2 of 2)

12. Fit camshaft gear retaining bolt to camshaft.
13. Screw tool 18G 1299A, into camshaft oil seal.
14. Remove oil seal by tightening centre bolt of tool 18G 1299A-1.
15. Discard camshaft oil seal.
16. Remove bolt from camshaft.

Refit

1. Inspect camshaft timing belt for signs of uneven wear, splitting or oil contamination, renew timing belt if necessary. See Adjustments.
2. Clean sealing area of cylinder head and camshaft carrier, ensuring all traces of rubber are removed. DO NOT use a scraper as this may damage sealing surfaces.
3. Lubricate sealing surfaces of new oil seal with clean engine oil.

4. Using tool 18G 1587 fit camshaft oil seal.
5. Clean camshaft gear.

CAUTION: If the sintered gears have been subjected to prolonged oil contamination, they must be soaked in a solvent bath and thoroughly washed in clean solvent before refitment. Because of the porous construction of sintered material, oil impregnated in the gear will emerge and contaminate a new timing belt.

6. Align camshaft gear timing marks and fit camshaft gear to camshaft.
7. Fit tool 18G 1570 to camshaft gears.
8. Fit bolt and washer securing camshaft gear to camshaft and tighten bolt to 33 Nm.

9. Check crankshaft pulley timing mark is aligned with mark on lower cover.
10. Using fingers only, fit timing belt over camshaft gears. Ensure belt run between the crankshaft gear and the camshaft gears is kept taut during the fitment procedure.
11. Check that timing belt is positioned centrally around all the gears and tensioner pulley.
12. Remove tool 18G 1570.
13. Loosen tensioner backplate bolt.
14. Rotate crankshaft 2 complete revolutions and align camshaft gear timing marks.
15. Tighten tensioner backplate bolt to 10 Nm.
16. Tighten tensioner pulley Allen bolt to 45 Nm.

CAUTION: Do not exceed the specified torque figure.

17. Fit camshaft timing belt upper cover. See this section.
18. Connect battery earth lead.
