Engine Assembly - Westerbeke 7.0 KW BGC -60Hz Technical Manual

ENGINE ASSEMBLY
Take the following precautions when assembling the engine:
A. Make sure that all parts to be assembled are thoroughly cleaned.
B. Be careful not to mix nuts and bolts. Metric and SAE bolts are used on various engine assemblies.
C. During the assembly, recheck clearances and ensure that all parts are assembled in their proper order
and face the correct direction in relation to the engine block; that is, pistons, piston rings, bearings and
bearing caps.
D. Apply lubricating oil to moving parts during the assembly. Ensure that moving parts, when assembled
on the engine, rotate or slide and are not subject to binding or excessive tension.
E.
If there are mating marks scribed during disassembly, reference them correctly for assembly.
F. Use new gaskets, lockwashers, and O-rings.
G. Tighten the bolts and nuts on important parts of the engine to specified torques using a reliable torque
wrench.
H. Use liquid sealants when required on nuts, bolts and gaskets. Refrain from using tape sealants.
