ENGINE REASSEMBLY
Position the piston at TDC at the end of the compression stroke. Put the timing gear
in seat without rotating the crankshaft and mount the chain.
Mount the water pump (8 Nm-0,8 Kgm-5.8 ft/lb+LOCTITE 542), without rotating the
crankshaft, in order to obtain the perfect alignement of the twin chasing on the gear
to the spline on head face (see picture) (tighten water pump fastening screws to 8
Nm-0,8 Kgm- 5.8 ft/lb+LOCTITE 542). Mount cylinder head-water pump hose.
