available. The pump is only available as a complete
assembly. The pickup screen, hose, and tube are the
only serviceable parts and are available separately.
ASSEMBLY
BEARINGS AND SEALS
(1) Using Remover C-4210 and Handle C-4171,
drive input shaft bearing from case from inside annu-
lus gear opening (Fig. 46).
(2) Install locating ring on new bearing.
(3) Position case so that the forward end is facing
upward.
(4) Using Remover C-4210 and Handle C-4171,
drive input shaft bearing into case. The bearing
locating ring must be fully seated on case (Fig. 47).
(5) Using Installer 6953, remove front output shaft
bearing.
(6) Start front output shaft bearing in case (Fig.
48). Then seat bearing with Handle C-4171 and
Installer 6953.
(7) Install front output shaft bearing retaining
ring.
(8) Install new front output seal in front case with
Installer Tool 6888 and Tool Handle C-4171 as fol-
lows:
(a) Place new seal on tool.Garter spring on
seal goes toward interior of case.(b) Start seal in bore with light taps from ham-

positioned to ensure proper shifting. Position the
clutch on the hub so a clutch spline is centered
over each strut as shown (Fig. 69). If the clutch is
installed so a gap between splines is aligned with
one or more struts, gear clash will result.
