Disassembling
• Disconnect the drive system, if this is the case, and check
conditions.
• Hydraulic drive: mark the position of the driven shaft on the pump
shaft.
• Remove the conveyor protection (21).
• Remove the aluminium conveyors (17).
• Loosen the 4 screws which blocks the locking set (53) and remove
the cooling fun (89) with the hub (7).
• Remove the seal cap (4). Do not lose compensation ring (69) and
seal cap gasket (35).
• Remove the vacuum pump flange (5) by using the threaded holes
to extract it. Do not lose OR-Ring (47).
• Hold the shaft before extracting the flange: the rotor weight must
not solicit the internal components.
• Extract the worn vanes (1).
• Complete disassembling;
- Extract bearing (50) and seal (46) from the pump flange (5);
- Extract seal (45) from the seal cap (4).
Checking the wear condition
• Check the condition of following parts:
- Seals and gaskets: they may be worn or have been damaged
during disassembling.
- Bushings: we recommend they be replaced if remarkably
scratched.
• A grinder may be needed to cut them for removal. Prevent iron
filings from entering the pump.
• Check whether the seal and the corresponding bushing need to be
replaced also on the pump rear according to their general condition.
Reassembly
• Oil and then insert all vanes in their seats.
• Vacuum pump flange (5): insert seal and bearing if they have been
previously removed or need to be replaced.
• Seal cap (4): insert the new oil seal if replacement has been
needed.
• Bushings on pump axle: new bushings may need to be warmed
before reassembly. Align them properly.
