5.2 Reassembly of Bearings and Seals (fi g. 26)
• Before reassembly all parts should be removed from the end cover (25) or (55).
Check parts (Pos. 10, 11, 12, 13, 14, 15, 17, 23) and if necessary replace.
• Fit new oil seal (10) with assembly device ( W
5
) into end cover (sealing lip see fi g. 26).
• Place sleeve type I ( W
1
) on shaft end (3) or (52) and lightly oil.
• Measure axial clearance between end cover and shaft according to the old seals (9) or (59) or calculate (length of h
seals (9 or 59) - rotor = clearance). The axial clearance is set at works and fi xed with dowels. If major work is necessary on
the housing, the tolerance given can be achieved by adjusting and pinning of housing and end cover.
• Important! To ensure correct and safe operation of the pump the data shown in the schedule below must be observed.
Please note different sizes of packing (9) or (59).
• Coat both sides of gasket (9) or (59) with anti-seize non-setting universal jointing material and position on end face of cylinder
housing (1) or (51).
• Push end cover over the dowels (2) and screw down loosely.
• Place stationary face (11) together with o-ring (13) on the sleeve type I ( W
1
) and insert in end cover (25) or (55).
• Slightly oil surface of stationary face (11) and sliding ring (15).
• Insert sliding ring (15) together with o-ring (12) to the stationary face (11) and pull off sleeve type I ( W
1
).
• Slightly oil spring (20) and insert in transport ring B (17).
• Place the transport ring B (17) over the shaft end, insert springs (20) and sleeves (19) in the holes of the sliding ring (15).
• Place spacer (43) if available next to transport ring B (17).
• Fit O-ring (14) and bearing (26).
• Screw washer (27) with screw and spring shim (28) at the shaft end (3) or (52).
• Place spacer (42), if required, next to bearing (26).
• Bearing cover (29) with O-ring (23) slip carefully over the shaft and tighten down.
• Tighten end cover and re-connect oil lines.
• Re-fi tting of stages and water jacket (see page 12).
