FIG: 11

NOTE: the exhaust pulley ﬁxing bolt should not be reused.

WARNING: Never attempt to loosen or tighten against the 8824 camshaft or crankshaft locking tools.

Component M – Tensioner Pulley Adjuster Tool

• With the crankshaft still seated against the crankshaft locking pin (K) and the camshaft

locked as shown in Figure 10 release the timing belt tensioner using the tensioner adjuster tool (M). See Figure 12.

FIG: 12

• Remove the belt leaving the pulleys on the camshaft with their ﬁxings ﬁnger-tight.

Camshaft drive belt ﬁtting:

NOTE: Before ﬁtting the new belt ensure the camshaft adjuster control valve and crankshaft sprocket are in good order as described in the manufacturer’s instructions.

With the crankshaft still seated against the crankshaft locking pin (K) and both camshafts locked as shown in Figure 10, ﬁt the new belt to the crankshaft pulley only.

Fit the lower timing belt cover and crankshaft pulley as detailed in the manufacturer’s instructions using an appropriate crankshaft pulley holding tool (see Laser 6998). Tighten the crankshaft pulley bolt to the correct torque and angle (see manufacturer’s data).

Fit the new belt to the rest of the pulleys in the following order – guide pulley, exhaust camshaft and the inlet camshaft.

Check the camshaft pulley ﬁxings are ﬁnger-tight only and the pulleys can turn independently of the camshafts. Tension the belt using the tensioner pulley adjuster (M) as detailed in the manufacturer’s instructions.

www.lasertools.co.uk

Page 11

Check the camshaft adaptor angles as detailed in the Checking Timing section above to ensure the camshafts have not moved (Figures 8 and 9).

Using the appropriate holding tools tighten the camshaft pulley ﬁxings to the manufacturers speciﬁed torque (Assembly torque only, not full ﬁnal torque, in this example around 20Nm).

NOTE: Every time the angles are checked always zero the inclinometer using the reference bar (G) ﬁgure 8 & 9. This is to ensure any change in the angle of the engine when for example raising or lower the vehicle ramp is compensated for.

Final checks:

Release the red and blue locking levers by removing the lever stop pins (L) as shown in Figure 13.

FIG: 13

Remove the crankshaft locking pin (K).

Turn the crankshaft 2 complete turns stopping just before returning to the TDC position and reinsert the crankshaft locking pin (K). Turn the crankshaft until it stops against (K).

Recheck the camshaft angles as detailed in the Checking Timing section (Figures 8 and 9) on pages 8 and 9.

Compare the reading to the manufacturer speciﬁcation. If no adjustment is required the camshaft pulleys can be tightened to the manufacturer’s full speciﬁcation.

If adjustment is required perform the following procedure:

Initial Camshaft Setting & Calculation of Correction Angles:

With the crankshaft still set against the crankshaft pin (K) lock the camshafts as detailed in Figure 10. Using an appropriate pulley holding tool loosen the inlet camshaft adjuster control valve and ﬁnger tighten. See Figure 11.

Using an appropriate pulley holding tool loosen the exhaust camshaft pulley bolt and ﬁnger tighten. See Figure 11.

NOTE: For camshaft holding Laser tools recommend Laser 8421 used with Laser 7279.

Place the inclinometer (I) upside down up against the inclinometer reference bar (G) as shown in Figure 8 and allow to stabilise.

Holding the inclinometer against (G) press ZERO to set the inclinometer to 00.0° and move the inclinometer to sit it on the ﬂat of the inlet camshaft adaptor (E) (the correct way up).

Insert a 6mm hex key into the end of the inlet camshaft adaptor (E) and while holding the hex key, unlock the inlet camshaft by removing the lever stop pin (L – inlet only).

Adjust the position of the camshaft using the hex key until zero (00.0°) is shown on the inclinometer and then lock the adaptor with the locking lever and reinsert the lever stop pin (L).

Repeat this procedure for the exhaust cam.

Once both camshafts are set to zero and locked, tighten the camshaft pulley ﬁxings to 20Nm.

NOTE: For camshaft holding Laser Tools recommend Laser 8421 used with Laser 7279. Re-check that both camshafts are still reading Zero, if not repeat the above process.

Release the red and blue locking levers by removing the lever stop pins (L) as shown in ﬁgure

13. Remove the crankshaft locking pin (K).

Turn the crankshaft 2 complete turns stopping just before returning to the TDC position and reinstall the crankshaft locking pin (K). Turn the crankshaft until it stops against (K).

Recheck the camshaft angles as detailed in the Checking Timing section (Figures 8 and 9) on pages 8 and 9.

Take note of the recorded values, these will be used to calculate the correction angle.

The correction angles for each camshaft have to be calculated. This is using the following equation.

(Speciﬁed Angle) – (Current Angle) = Correction Angle

See examples opposite:

Example calculation

Use vehicle manufacturer’s engine speciﬁc data and measured camshaft timing angle from previous section.

www.lasertools.co.uk

Page 13

EXAMPLE ONLY:

Engine code DADA (1.5lt)

Speciﬁed Inlet timing angle -0.3° +/- 1.2° (manufacture data, engine speciﬁc)

Speciﬁed Exhaust timing angle +1.1° +/- 1.2°

Current Inlet Camshaft Timing Angle (Measured Angle) = (

0.9°) -0.9°

(Speciﬁed Angle) – (Current Angle) = Inlet Correction Timing Angle

(-0.3°) – (-0.9°) = +0.6° turn 0.6° clockwise from Current Angle.

Inlet Calc.

NOTE: Arrows indicate the direction to rotate to reach zero.

Speciﬁed = -0.3 Actual = -0.9 Correction = +0.6

Current Exhaust Camshaft Timing Angle (Measured Angle) = ( 1.0°) -1.0°

(Speciﬁed Angle) – (Current Angle) = Exhaust Correction Timing Angle

(+1.1°) – (-1.0°) = +2.1° turn 2.1° clockwise from Current Angle.

Exhaust Calc.

NOTE: Arrows indicate the direction to rotate to reach zero.

Speciﬁed = +1.1 Actual = -1.0 Correction = +2.1

Final Setting of timing:

NOTE: Once the Correction Angle is identiﬁed, the camshafts must be set to Zero

and then adjusted from zero by the Correction Angle to compensate for the engine manufacturer’s tolerances.

Using an appropriate pulley holding tool loosen the inlet camshaft adjuster control valve and ﬁnger tighten. See Figure 11.

Using an appropriate pulley holding tool loosen the exhaust camshaft pulley bolt and ﬁnger tighten. See Figure 11.

NOTE: For camshaft holding Laser Tools recommend Laser 8421 used with Laser 7279.
