Thank you

All overhead (valve and injector) adjustments must be made when the engine is cold (any stabilized coolant temperature at 60°C [140°F] or below).

Do not apply crush to the injector timing plunger by further tightening the adjusting screw. Doing so will result in an incorrect injector lash setting and can cause excessive injection train wear.

Tighten the adjusting screw on the injector rocker lever until the timing plunger just touches bottom.

After bottoming the CELECT Plus injector timing plunger, make certain to back out the adjusting screw two flats (120 degrees) or damage to the injector will result.

Back out the adjusting screw on the injector rocker lever two flats (120 degrees).

Two flats will provide 0.56 mm [0.022 in] lash. The specification is 0.50 to 0.74 mm [0.020 to 0.029 in] lash.

Valve Lash Specifications

Intake

0.35 mm [0.014 in]

Exhaust

0.68 mm [0.027 in]
