INSPECTION POINT: VERIFY GASKET THICKNESS PRIOR TO
INSTALLATION.
10.9.1 When replacing annular ball bearing (25) gaskets (see para 11.6), apply a thin, even amount of
Hylomar compound to both sides of EACH clutch gasket (24) (previously calculated). Apply a thin, even
amount of Hylomar compound to the mounting surface of seal plate assembly (23) and the output housing
(26).
10.9.2 Install clutch gaskets (24) on output housing (26). Align gasket bolt holes with the output housing
(26) bolt holes.
CAUTION
Do not oversize seal. If seal becomes oversized, remove seal and re-
place with a new one. Once seal has been properly formed apply a
small amount of Mobilgrease28 to seal surface and install rotating
flange (17) into seal to retain its shape.
CAUTION
Do not deform seal housing during installation. Remove excess com-
pound.
10.10 Form plain encased seal (18) using seal forming tool (P/N 298170-1, Figure 10) by placing tool into
the seal inner diameter from the input housing side. Push forming tool through while rotating tool to form seal.
Push forming tool through encased seal (18) until forming tool goes completely through the seal. Do not pull
back on the forming tool during seal forming process. The seal diameter should be approximately the size
of the flange's (17) seal riding surface.
10.11 Apply lubricant Mobilgrease28 to seal (18).
10.12 If not previously accomplished, install rotating flange (17) through plain encased seal (18).
INSPECTION POINT: VERIFY SEAL IS UNDAMAGED DURING
INSTALLATION AND IS SEATED TIGHTLY AGAINST THE ROTATING
FLANGE (17) SEALING SURFACE.
10.13 Apply Mobilgrease28 to the bearing (25) surface and the housing (21) surface to assist in the
installation of the bearing into the housing.
10.14 Hold rotating flange (17) and carefully place output housing (26) over splined adapter (19). Align
rotating flange (17) so the flat surfaces on the flange's inner diameter are aligned perpendicular to the output
housing's weep hole. The weep hole is located at the clutch 6 O'clock position near the bolt (21).
