Diesel engine 17YD 1.7 l
Attention! For correct adjustment of valve timing, it is important that the toothed belt of the camshaft drive is correctly tensioned. The belt tension can only be accurately checked using a special device Opel KM-510A.
Check the timing belt tension.
Set cylinder #1 to TDC.
Adjustment using the measuring bar KM-238-2 and the indicator MKM-571

Instead of a measuring bar, you can use a steel ruler to which the indicator is attached.
Install the measuring bar on the camshaft housing (see fig.).
Place the indicator leg on the 2nd cam and set the indicator to "0". This cam operates the intake valve of the 1st cylinder. Make sure that the indicator leg has a flat, not convex surface.
Attention! Rest the indicator leg on the back of the cam, not on its protrusion!
Apply marks "0" and "10" (mm) to the measuring bar.
Move the indicator with the measuring bar in the direction of the cam protrusion to the "10" mark.
Loosen the camshaft timing pulley fastening.
Using a 22 mm wrench, turn the camshaft clockwise until the indicator leg rises by 0.55±0.05 mm.
Holding the camshaft in this position, screw in a new toothed pulley mounting bolt and tighten it to a torque of 75 Nm. Then tighten the bolt another 60-65°. When tightening, do not allow the camshaft to turn.
Attention! After securing the camshaft pulley, check the valve timing again.
Check injection advance and adjust if necessary.
