Removing –  Remove poly V-belt → Chapter. –  Remove toothed belt → Chapter. –  Remove sump → Chapter. –  Remove sealing flange at belt pulley end → Chapter. –  Unscrew securing bolts for cover. –  Unclip cover from retaining frame.

–  Lock chain tensioner using locking pin -T10060 A--arrow-. –  Remove idler chain sprocket -1- from retaining frame. –  Remove securing bolts -2- from chain tensioner and remove chain tensioner. –  Remove chain from sprockets and place chain on a clean surface.

–  Lock balancer shaft using a 24/27 mm spanner -1-.  Note The spanner must be positioned centrally to the balance weight and at right-angles to the balancershaft. –  Loosen securing bolt -2- for balance weight. Note Only loosen securing bolt -2- for balance weight, do not remove. –  Unscrew retaining frame -3- from cylinder block and remove retaining frame together withbalancer shaft. –  Place retaining frame on a clean surface. –  Remove securing bolt from balance weight. –  Remove balance weight and sprocket from balancer shaft. –  Turn balancer shaft so that the shaft can be taken out of the bearings. Installing –  Lubricate running surfaces of bearings. –  Insert balancer shaft into the bearings. –  Fit sprocket and balance weight on balancer shaft. Note The sprocket and the balance weight can only be fitted in one position. –  Tighten securing bolt for balance weight and sprocket hand-tight. –  Bolt retaining frame hand-tight to cylinder block so that there is no play.   Note t  Ensure when installing the retaining frame that the dowel sleeves are fitted in the cylinder block and the O-ring is fitted in the retaining frame. t  Align the retaining frame so that the belt pulley end is flush with the outer edge of the cylinder block. –  Bolt retaining frame with balancer shaft to cylinder block. Torque setting: 20 Nm. –  Check that the belt pulley end of the retaining frame is aligned flush with the outer edge of the cylinder block

–  Lock balancer shaft using a 24/27 mm spanner -1-.
