3.7 INSPECTION AND ADJUSTMENT, VALVE CLEARANCE

1. Remove the valve covers, see "Removal and
installation".
2. Use the special tool (DAF no. 1310477) to
turn the crankshaft clockwise, as seen from
the timing gear end (this corresponds with
the engine's direction of rotation), until the
valves of cylinder 1 are in the overlap
position. The pistons of cylinders 1 and 6 are
now at top dead centre.
Note:
"Overlap" is the moment at which the inlet
valve starts opening and the exhaust valve
finishes closing.
}
If the engine has a DEB, you must
use a flat ring spanner to loosen the
lock nut. This is necessary to avoid
damaging the DEB spring plate.
3. Check/correct the valve clearance of
cylinder 6. Set the correct valve clearance by
loosening the lock nut and turning the
adjusting screw in the correct direction. See
"Technical data" for the correct valve
clearance.
