16. Remove bolt and remove timing chain lubrication jet.

17. Using tool LRT-12-092, remove and discard oil seal from timing cover.

Inspection

1. Clean all components.
2. Check condition of timing chain running surfaces on adjustable and fixed guides.

CAUTION: Adjustable guide fitted to Engine Serial No. Prefixes 15P to 19P may be fitted to early engines provided that timing chain tensioner having a YELLOW coloured body is also fitted.

3. Check timing chains and sprockets for signs of wear.

CAUTION: Timing chains and sprockets fitted to Engine Serial No. Prefixes 15P to 19P may be fitted to early engines as an assembly only, oil pump drive sprockets are interchangeable. Later timing chains have BRONZE coloured timing links.

4. Check that drilling in timing chain lubrication jet is clear. 10. Remove and retain crankshaft pulley bolt.
5. Clean oil seal recess in timing cover and oil seal 11. Fit Woodruff key to crankshaft. running surface on crankshaft. 12. Fit oil pump drive chain to rear row of teeth on
6. Remove all traces of sealant from mating faces of timing cover and cylinder block using suitable solvent. 13. Fit sprocket to crankshaft ensuring that timing

CAUTION: Do not use metal scrapers.

14. Fit oil pump drive sprocket to oil pump and drive
7. Ensure bolt and dowel holes are clean and dry.
8. Clean oil pump sprocket bolt threads.
1. Fit timing chain lubrication jet.
2. Fit timing chain lubrication jet Torx screw and tighten to 10 Nm (7 lbf.ft).
3. If crankshaft has been rotated, check that No.1 piston is at TDC using the following procedures:

4. Temporarily fit and lightly tighten a new crankshaft pulley bolt.
5. Assemble a magnetic base DTI to cylinder block top face, position stylus to cylinder block face and zero gauge.
6. Using crankshaft pulley bolt, rotate crankshaft clockwise until No.1 piston is at top of its stroke and woodruff key slot in crankshaft is at 12 o'clock position.
7. Position stylus of DTI to No.1 piston crown and rotate crankshaft until highest reading is indicated on DTI.
8. Check that Woodruff key slot is still at 12 o'clock position indicating No.1 piston is at TDC firing.
9. Remove DTI.
