DISASSEMBLY/REASSEMBLY
Tappet cover disassembly
Unscrew the four M6x20 hex screws to disassemble the tappet cover, check the seal ring and replace it - if necessary - before
reassembly (fig. 101).
Camshaft extraction
Turn the shaft and bring the cam lobe to coincide with the opening provided for (Fig. 102).
Repeat the procedure on the second cam to extract the shaft completely (Fig. 103).
Tappets - Disassembly
To remove the tappet shims, rotate the tappets until it is possible to insert a
screwdriver into one of the special cuts to detach the shim from the tappet itself.
The surface of the adjusting collar on which the shim identification number is
marked should be facing the tappet socket.
If you are using the same tappets, because they are not worn-out, mark both
tappets and shims before disassembly, in order to be able to reassemble them
in the same position – i.e. the exhaust tappet into the exhaust and the intake
tappet into the intake.
