MOUNTING AND DISMOUNTING THE ENGINE (J05E) 5–6
(3) Insert a thickness gauge in between the rocker arm and the
crosshead and turn the rocker arm adjust screw to adjust a clear-
ance before tightening the lock nut.
Tightening Torque:
25 N·m {255 kgf·cm, 18 lbf·ft}
NOTICE
It is deemed appropriate if the thickness gauge goes in with some
unsmoothness during insertion and then moves smoothly with
slight binding feel after insertion.
(4) With the thickness gauge inserted, loosen the adjust screw of the
crosshead and check that you do not feel the thickness gauge
light.
! CAUTION
If you feel it light, repeat the procedure.
(5) Tighten the adjust screw of the crosshead until the thickness
gauge does not move.
(6) While gradually loosening the adjust screw of the crosshead,
tighten the lock nut of the crosshead at a position where your feel
of the thickness gauge becomes proper.
Tightening Torque:
25 N·m {255 kgf·cm, 18 lbf·ft}
! CAUTION
Do not loosen the adjust screw too much. If the adjust screw is
made too loose, the former state will be restored. Although you
may get proper feel with the thickness gauge, a gap will be pro-
duced between the adjust screw of the crosshead and the valve
and you cannot make correct adjustment.
NOTICE
It is deemed appropriate if the thickness gauge goes in with some
unsmoothness during insertion and then moves smoothly with
slight binding feel after insertion.
