Gradall LOED 534A Service Manual - Manual (Page 49)

Install the drive gear and idler
gear. The drive gear should be in
the bore nearest the identifying
mark made in Step 2, with the
splined end up. (Figure 56)
Install body dowels (20), one near
the drive gear and the other near
the idler gear.
For proper timing of the gears
6 and 8 with gears 5 and 7, see
sketch.
Install pressure plate (9), bronze
side down against the gear faces
and with the trap slots facing the
discharge side of the body.
(Figure 57)
26. Install the isolation plate (10)
with its square edges on the suction
port side. Install back-up ring
(14), o-ring (12), and retainer (13)
on the discharge side. (Figure 58)
Install o-ring (25) in the bearing
plate (3) on the side which has the
bearings extending beyond the plate
surface. Use heavy grease to hold
the o-ring in postilion. (Figure 59)
With the o-ring down, and the
identifying mark made in Step 2
facing you, slide the bearing plate
(3) down on the shafts until the
plate makes contact with the dowels.
Use caution and keep the plate
level. If the surfaces are not
parallel when the bearing enters the
back-up ring (14), the bearing will
pinch and damage the back-up ring.
