use grease)
shaft and inner surface
of bellows on rotating member. With
lapped surface facing bearing bracket
(15), slide rotating member onto shaft
using seal pusher tool, until lapped faces
are together. It is extremely important to
keep seal faces clean during assembly.
Dirt particales lodged between faces will
cause the seal to leak.
Be sure driving lugs in retainer are
matched in rotating member of seal (19).
Place spring over shaft and in place on
rotating member, making sure it is seated
in retainer and not cocked or resting on
bellows tail. Lightly oil shaft and inner
surface of outboard rotating member.
With tail section toward bearing bracket
(15), slide rotating member onto shaft
with seal pusher tool until retainer
engages spring and spring is compressed
slightly. Spring should be properly
engaged in both retainers.
Reassemble the diaphragm (23) with
“bulg” facing seal plate (24). Place plate
(44) on diaphragm (23) and insert
capscrews (45) into plate and tighten.
Place seal plate (24) over shaft onto
bearing bracket (15), being careful not
to damage outboard stationary member
and align holes for cap screws (25).
Thread cap screws (25) into bearing
bracket (15) and tighten. Refi ll chamber
