Procedure
Removing
Loosen toothed belt pulley for exhaust camshaft
- Remove upper part of toothed belt guard ⇒ 2.3.1 Removing and installing upper toothed belt guard.
- Set piston in cylinder no. 1 to TDC position ⇒ 4.7 Setting piston to TDC position.
- Loosen bolt -1- approx. one turn using counter-hold tool - T10172- with adapter -T10172/2- and -T10172/1-.
Remove toothed belt pulley for exhaust camshaft:
- Loosen camshaft adjuster -2- of inlet camshaft ⇒ Fig. ““Loosening camshaft adjuster on inlet side:”“, page 164.
- Hold inlet camshaft in position using counter-hold tool - T10172- and adapter - T10172/1-.
- Loosen bolt -1-.
- Detach toothed belt from camshafts. ⇒ 2.7 Removing toothed belt from camshaft
- Unscrew securing bolt -1- of toothed belt pulley, and remove toothed belt pulley.
Installing
- Camshafts are located in “TDC” position.
- The camshaft pulleys are properly aligned with each other.
- Crankshaft is in “TDC position”.
- Renew bolt -1- for camshaft adjuster on inlet side, and screw it in to stop by hand.
- Renew bolt -2- for toothed belt pulley on exhaust side, and screw it in to stop by hand.
- It should just be possible to turn camshaft pulleys on camshafts but no rocking is permissible.
- Fit toothed belt in position and adjust valve timing ⇒ 2.7 Removing toothed belt from camshaft.
Pre-tightening
- Hold inlet camshaft in position using counter-hold tool - T10554- and counter-hold tool - T10172-.
- Pre-tighten bolt -1- to specified pre-tightening torque in two stages.
| Stage | Securing bolt for camshaft adjuster | Torque setting |
|---|---|---|
| 1. | -1- | 15 Nm |
| 2. | -1- | 50 Nm |
- Hold inlet camshaft in position using counter-hold tool - T10172- and adapter - T10172/1-.
- Pre-tighten bolt -1- to specified pre-tightening torque in two stages.
| Stage | Securing bolt for toothed belt pulley | Torque setting |
|---|---|---|
| 1. | -1- | 15 Nm |
| 2. | -1- | 50 Nm |
Tightening to final specified torque
- Tighten bolt -1- for camshaft adjuster to final specified torque.
| Stage | Securing bolt for camshaft adjuster | Angle to turn bolts |
| 1. | -1- | 135° |
- Tighten securing bolt for toothed belt pulley on exhaust side to final specified torque.
| Stage | Securing bolt for toothed belt pulley | Angle to turn bolts |
| 1. | -1- | 90° |
- Screw in plug -1-, and tighten it to specified torque.
- Hold inlet camshaft in position using counter-hold tool - T10172A- and counter-hold tool - T10554-.
| Stage | Plug for camshaft adjuster | Torque setting |
| 1. | -1- | 20 Nm |
Installing
Further assembly is performed in the reverse order of removal.
