4
Press out the rocker bushing with mandrel no.
9991967 for the 6(x) series, or 9992677 for the 7(x)
series.
5
Turn the mandrel over and press in a new bushing.
NOTE! Make sure that the oil hole in the bushing is
centred on the oil duct in the rocker arm.
6
Machine broach the bushing to give an accurately ad-
justed running fit on the shaft.
22.020–22.041 mm for the 6(x) series, or
25.020–25.042 mm for the 7(x) series.
Remove all swarf.
7
Oil the rocker shaft and install all the components.
Note that the rockers on the 6(x) series are installed in
opposing pairs. On the 7(x) series, all the rockers are
identical and the location on the shaft is thus arbitrary.
Make sure that the circlips on the rocker shaft ends
have seated securely in their grooves.
