To insert the bushing (6), proceed as follows:
Unscrew the grip (l) and the extension (N).
Position the extension (N) and the guide bush (E) as shown
in the figure.
Position the bush to insert on the drift (A) making the dowel
pin (B) on it coincide with the seat on the bush.
Position the guide bush (E) and secure the guide bush (G) on
the seat of the 7
th
bush with the plate (H) .
While driving in the bushing, make the reference mark (F)
match the notch (M). In this way, when it is driven home, the
lubrication hole on the bush will coincide with the oil pipe in
its seat.
NOTE Bush fitting is finished when the 1st reference
notch (D) is flush with the guide bush (G).

NOTE The camshaft cams directly control the 12 rocker arms for the valves.
The intake valve control rocker arms are keyed directly onto the rocker arms shaft.
Exhaust valves control rocker arms are keyed onto the rocker arms shaft interposing the levers with engine brake
control eccentric pin. The rockers slide on the cam profiles via rollers.
The other end acts on a bar supported by the stem of the two valves.
There is a pad between the rocker arm adjustment screw and the crosspiece.
There are two lubrication pipes inside the rocker arms.
Check the shaft surfaces for signs of seizure, scoring or wear. Otherwise replace the shaft.
