Installing
Specified torque ⇒ 5 Balancer shaft module
- Check chain drive components for wear.
- Screw balance shaft module onto cylinder block hand-tight.
- Align the balance shaft module so that the belt pulley end is flush with the outer edge of the cylinder block.
- Check that marking -arrow- on crankshaft sprocket is positioned almost at top.
- Clean chain with a lint-free cloth.
- Fit chain onto chain sprockets of crankshaft, oil pump and balance shaft as shown in illustration.
- Marking on crankshaft sprocket must align with single colour marking on chain link -top arrow- in this case.
- Marking on balance shaft sprocket must be located between 2 colour markings on chain links -bottom arrow-.
- The colour markings are only on the outer plates of the chain. They must be on the outside. This also guarantees the original direction of rotation of the chain.
- Insert guide sprocket into chain, and bolt to balance shaft module at 23 Nm.
- Install chain tensioner.
- Replace bolts -2- and tighten as follows.
| 1) | Centre bolt | 8 Nm |
|---|---|---|
| 2) | Bolt on oil pump | 8 Nm |
| 3) | Bolt on guide rail | 8 Nm |
| 4) | Centre bolt | Turn 90° (1/4 turn) further |
| 5) | Bolt on oil pump | Turn 90° (1/4 turn) further |
| 6) | Bolt on guide rail | Turn 90° (1/4 turn) further |
- Remove locking pin - T40011- from chain tensioner.
- Check whether markings on sprocket/crankshaft and sprocket/balance shaft are still positioned correctly to colour markings on chain links -arrows-.
- Install sealing flange on belt pulley end ⇒ 1.9.2 Ancillary bracket (removing and installing).
- Install balance shaft cover.
- Install sump ⇒ 1.3 Removing and installing sump.
- Install toothed belt ⇒ 2.1.1 Removing and installing engine bracket.
