supports and pulling splined shaft
out of bevel gear, without removing
jackshaft (horizontal swing shaft)
removed in step (3) above. This
procedure may be used when
suspected damage is to pinion shaft
and bearings, rather than to bevel
gear.
b. Disassembly.
(1) Remove cotterpin (9, fig. 4-14), nut (7),
and washer (6) from bottom of pinion shaft (8).
(2) Remove bearing (5) and collar (4) from
threaded end of pinion shaft (8).
(3) Remove bearing (1) and bevel gear (2)
from pinion shaft (3), when jackshaft has been removed.
(4) Remove pipe bushing (14) from bearing
retainer cap (12).
c. Cleaning, Inspection, and Repair.
(1) Clean all parts and dry thoroughly.
(2) Inspect pinion shaft and bevel gear (if
removed) for chipped or worn teeth. Inspect shaft for
straightness or worn bearing surfaces Inspect bearings
carefully for wear or damage. Inspect collar for shaft fit
assuring no looseness from excessive wear.
(3) Repair or replace defective components
and damaged mounting hardware.
d. Reassembly.
(1) Position collar (4, fig. 4-14) with bevel
edge first on shaft (3) then press bearing (5) on shaft
until snug against collar.
(2) Install washer (6) and nut (7), on shaft (8)
and secure with cotterpin (9).
