Mounting Speedi-Sleeve
The mounting procedure is as follows
(fig 81):
1 The final position of the sleeve on the shaft
should be determined and marked. The
sleeve should cover the wear tracks of the
old seal and not just left flush with the shaft
end.
2 Push the sleeve on to the shaft with the
flanged end first. The mounting tool
supplied with the sleeve is then pushed on
to the sleeve. If the tool is not long enough
a length of pipe of tubing with square,
deburred ends can be used instead.
3 Apply light mallet blows centrally to the
mounting tool until the sleeve has been
driven up to its final position. Be careful not
to damage the outside diameter of the
sleeve.
4 Remove the flange if necessary. It is
important that this is only done after the
sleeve has reached its final position. The
flange should be cut through to the tear
groove after which it can be peeled off along
the groove using a pair of tongs. If the
flange is not in the way when other parts
are being assembled and if it will not foul
another component in operation, it is
recommended that it be left in position.
5 After the sleeve has been installed, check
the shaft end again for burrs which could
damage the new seal.
6 Lightly oil or grease the Speedi-Sleeve
surface and, if necessary, the shaft end to
ease mounting the seal. Use the same
lubricant as that which the seal is to retain.
Removal
A Speedi-Sleeve can be dismounted in one of
the following ways; by applying heat to the
sleeve; by using a pair of wire cutters starting
at or near the flange and applying a twisting
action; by “peening” with a small hammer
across the full width of the sleeve to expand it
or, if accessible, by using a drift on the flange.
A Speedi-Sleeve cannot be re-used.
