Maintenance Procedures (cont’d)
Shaft Seal Repair Kit
Removing old Shaft Seal
• Remove the bolts of the seal housing (1)
• Extract inner ring (4) from the shaft
• Be careful not to damage the shaft
• Clean surfaces carefully
Installing the new Shaft Seal
• Apply Loctite 641 sealant on the inner surface
of the new inner ring (4)
• Carefully wipe off excess sealant immediately
• If ring is heated, twist it 90º after it is installed,
this will spread the sealant evenly on the
surfaces
• The ring (4) must be heated to a maximum
temperature of 150°C (302°F) to allow it to be
installed on the Air End
Installing the O-Ring
• Install the new o-ring (2) onto the air end (5)
• Use heat-resistant grease to hold the o-ring in
place
Installing new Seal Housing with new Shaft Seal
• Place DSC-002953 installation shaft sleeve
tool (6) on the shaft of the air end
• Push the seal housing (1) onto the rotor shaft
and hold it against the shaft seal inner ring.
(The oil seal (3) is pre-installed onto the seal
housing (1) at the factory)
• Then push the seal housing (1) carefully into
final position
• Install the housing tightening the screws to
7.9-8.7 Nm (5.8-6.4 ft.lb)
• Remove the DSC-002953 installation shaft
sleeve tool
The parts as indicated by the arrows (1 to 4) are
included in the ‘DSC-002718’ Shaft Seal Repair Kit.
Item 6, the ‘DSC-002953’ Shaft Sleeve Tool, must be
purchased separately. Failure to use this Sleeve in the
installation of the new Seal will potentially allow the
Shaft Seal to leak as it was not installed correctly. If
you wish, the Tool can be returned to DV Systems for
credit.
