INFORMATION FOR DISASSEMBLY
7.12 Engine block disassembly
7.12.1 Piston unit / connecting rod
Important
• Mark some numerical references (cylinder n°) on the
connecting rods, connecting rod caps N, pistons and gudgeon
pins to prevent unintentionally confusing the components not
replaced during assembly. Failure to do this may result in
engine malfunctions.
• References on connecting rod M and cap N must only be
carried out on a side in correspondence with K1 and K2 , as
illustrated in Fig. 7.33.
1 - Unsrew bolts M and remove the connecting rod caps N.
NOTE: coupling cap N on the connecting rod can be carried
out with centring taper pins (Fig. 7.34) or broken (Fig.
7.35 - without centring taper pins).
