Installation, use and maintenance
M0033E
GEAR UNIT
To reach the gear unit components:
a. Remove the cover.
b. Loosen the screws.
c. Remove the plate. Now all gears canbe reached for inspection. Should the gasket be replaced, remove the
bevel gear from the shaft by pulling axially,then remove the gear together with theshaft. The gasket replace-
ment always requires the replacement of the bush provided with the spare part kit. Toreassemble reverse the
above described procedure paying particular attention to:
• Lubricate the O ring before installation.
• Check that the gear unit can rotate freely before fixing the cover
9 COMPATIBILITY

tions in section “Measuring chamber”
• Soiled or blocked measuring chamber. Clean the measuring chamber follow-
ing the instructions in section “Meter
unit”
• Air in the fluid Locate and eliminate leaks in inlet lines
Reduced flowrate • Clogged or blocked measuring cham-
ber
Clean the measuring chamber follow-
ing the instructions in section “Measur-
