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)
