REPLACEMENT OF BALL BEARING IN HANDWHEEL COUPLING (See Figure 37)
The handwheel screw ball bearing (5) with one piece bearing housing (3) is a non-adjustable coupling arrangement. In
the event of ball bearing wear the bearing (5) for each handwheel screw (1) should be replaced as follows: (Refer to the
above illustration for numbered items.)
A. Remove the screed end plate. Drive out wedge keys and remove the small access late under the screed walkway to
expose the hold-down screws (6).
B. Remove the four capscrews (6) which attach the housing (3) to the deck plate.
C. Remove the four capscrews (10) which secure the upper ball joint. Remove cap (I 1) so that the entire handwheel
screw assembly can be lifted off the screed.
D. Unscrew and remove retaining screw (7) and washers (8).
E. Pull the screw shaft (1) out of the ball bearing (5).
F. Turn ball bearing (5) 900 in the housing so that it can be aligned with the slots in the housing and driven out the
bottom opening.
G. Replace the snap ring (2) on the screw shaft if necessary.
H. Install the new ball bearing and re-assemble all parts by reversing the dismantling procedure.
I. Pump bearing chamber full of grease.
