Position the lower bushing (29) so that it rests against the stop ring (27) and
then fit the floating bushing (28) into the rod from the side with oil holes. Insert
the upper bushing (26) and screw it with the lower one.
Keep the upper bushing with the 18-mm wrench and tighten the lower
bushing at the indicated torque.
FIG. 35
Insert the spring guide (24) into the rod (32) from the side with smaller
