After assembling the pump, position the gear on the
shaft and assembly. Once there is not timing on this
gear the pump shaft does not have cotter for
positioning.
Position gear washer and fixation nut and apply the
specified torque.
The protective caps must be removed only
immediately before the piping assembly, avoiding
contaminations.
Attention
• The cone of the high pressure pump shaft and the gear must be clean and free of oil
and grease before the fixation. The materials for cleaning can be: test benzene, ethyl
alcohol, glycol or isopropanol.
• The high-pressure pump, due to its lubrication by the fuel, in any case may work dry.
Before the first start, fill approximately 60 ml of fuel to guarantee the lubrication of the
inner parts. For the first filling, a electric fuel pump can be used with minimum pressure
of 2 bar and 4 bar maximum.
