and press it flat on the housing seat.
Fig. 4
l
Press or knock the seal into the housing, until it is
flush with the housing surface.
i Note
If possible, use a "bell" (1 (Fig. 4)), to make sure that
the seal will not skew. In some cases it may be ad-
visable to assemble the seal into the housing first, be-
fore sliding it over the shaft. Under no circumstances
should the full weight of the shaft rest on the seal.
If you have no proper service tools at hand, use a suit-
able drift punch with a diameter which is about 0,4 mm
smaller than the outer diameter of the seal. Use VERY
LIGHT blows with the hammer if no press is available.
