ENGINE ASSEMBLY

Ed. 05-2011

General

To reassemble, reverse the disassembly procedure. Any special instructions concerning reassembly operations are expressly high-

lighted in the text. Gaskets, oil seals, metal clips, sealing washers in deformable material (copper, aluminium, fibre etc.) and self-

locking nuts must always be replaced.

Bearing specifications and dimensions have been calculated for a certain operating life.

We recommend replacing the bearings - especially those exposed to heavy loading - also considering that checking them for wear 

is not an easy procedure.

These recommendations are in addition to the dimensional checks of individual components specified in the relevant section (see 

Section “ENGINE OVERHAUL”).

Cleaning all components thoroughly is critical to reliability; bearings and any wear parts must be lubricated with engine oil before 

assembly.

Screws and nuts must be locked to the tightening torque figures indicated.
