Tank level indicator adjustment
The level indicator reading should be checked regularly. When the tank
is empty, the float should lie on the stop pin, of the rod, and the O-ring
on the indicator should be positioned at the top position line (A).
If any deviation is found, pull out the plug (B), loosen screws (C), and
adjust the length of the cord.
Replacing the valves and 363 and 463 diaphragms
Model 363
The repair kit for the 363 diaphragm pump (valves, seals, diaphragms,
etc.) is available under HARDI part No. 750342.
Valves
Remove crankcase cover before replacing the valves. Remember their
direction in order to assemble them correctly afterwards!
ATTENTION! When you remove the crankcase covers, you will
see that there are 2 valves that are slightly different from the
rest. For correct operation, remember to fit them in the same
position and location as before.
Diaphragms
Remove the diaphragm cover. The diaphragm can then be replaced.
If the liquid has leaked to the inside of the crankcase, grease the
pump thoroughly. Make sure that the drain hole at the bottom of the
crankcase is not blocked. Reassemble the pump completely.
The torque wrench settings for the 363 and 463 pumps are the
following:
Crankcase cover: 90 Nm
Diaphragm bolt: 90 Nm
ATTENTION! Before tightening the four screws on the crankcase
cover, the diaphragms should be centered to ensure correct
seating and sealing between the crankcase and the cover. Turn
the crankshaft if necessary.
