Timing Belt Replacement (Alt. & P/S Belt Removed):
- Support engine
- Remove Engine mounting Bracket
- Remove Alternator
- Remove timing belt upper cover
- Turn crankshaft clockwise to TDC on Cyl. 1 ensure timing marks are aligned (2) & (3)
- Loosen crankshaft pulley bolt (6) but do not remove
- Remove tensioner unit (5)
- Remove timing belt from cam shaft sprockets
- Prevent crankshaft from turning whilst removing crankshaft pulley bolt
- Remove crankshaft pulley (7)
- Remove timing belt lower cover
- Remove crankshaft sprocket guide washer (9)
- Remove Timing Belt
- Remove tensioner pulley bolt (10)
- Remove tensioner pulley (11)
- Check tensioner pulley for smooth operation if its notchy or ceased replace with new unit
- Fit tensioner pulley, apply locking compound to bolt threads, avoiding leading threads, and tighten to 43 Nm (31.7 Lb-Ft)
- Fit new timing belt in ANTI-CLOCKWISE direction whilst ensuring belt is taut between sprockets
- Refit crankshaft guide washer
- Refit timing belt lower cover
- Refit crankshaft pulley and retaining bolt to prevent pully slipping off.
- Ensure timing marks are aligned (2) & (3)
- Check tensioner body for leakage or damage and replace if necessary
- Check pushrod does not move when pushed against a firm surface if pushrod moves replace unit
- Check push rod protrusion is10-11mm (12) if not replace unit
- Slowly compress push rod into tensioner body until holes aligned. Use vice or press
- Retain pushrod with 1.27mm allen key through hole in tensioner body (13)
- Install tensioner Unit (5)
- Tighten tensioner unit bolts (4) to 21Nm (15.5 Lb-Ft)
- Turn tensioner pully bolt ANTI-CLOCKWISE with a torque of 69Nm (50.9Lb-Ft) (14)
- Remove allen key from tensioner body to release pushrod (13)
- Remove torque wrench(14)
- Turn crankshaft 2 turns CLOCKWISE to TDC Cyl.1 ensure alignment of timing marks (2) & (3). If not aligned repeat installation and tensioning points (pain in the arse I know but if you take your time first time round then it should be spot on)
- Install remaining components in reverse order of removal
- Tighten crankshaft pulley bolt (6) to 108Nm (79.7 Lb-Ft)
