universal joints are serviced as assemblies. Each of the
three universal joint types can be disassembled for in-
spection and replacement purposes.
Disassembly-Single C i f l i t Joint •; "' • -
(1) If slip yoke universal joint is to be replaced,
• paint alignment marks on slip yoke and propeller shaft
for assembly reference and remove slip yoke from shaft.
(2) Remove loose bearing caps from spider and ap-
ply penetrating oil to bearing caps seated in shaft yoke.
(3) Mount propeller shaft or slip yoke in vise.
CAUTION: Do not clamp the propeller shaft tube in
the vise. Clamp the forged portion of the slip yoke or
propeller shaft yoke in the vise only. Also, to avoid
distorting either of the yokes, do not overtighten the
vise.
(4) Remove bearing cap retainers (fig. 2E-5). Tap
ends of bearing caps with hammer to relieve pressure on
retainers if necessary.
(5) Reposition shaft in vise so yoke is supported on
vise jaws.
• (6) Tap end of one bearing cap with hammer until
opposite 'bearing cap is driven out of yoke.
(7) Reposition shaft yoke in vise and tap exposed
end of spider to drive remaining bearing cap out of yoke.
(8) Remove spider from yoke.
Cleaning i l l Inspection
Clean the yoke bearing cap bores with solvent and a
wire brush. Be sure to remove all rust, corrosion, or dirt.
Wash the bearing caps, bearings and spiders in solvent
and wipe them dry with a shop cloth.
Inspect the bearing caps, needle bearings, and bearing
surfaces of the spider for evidence of brinneling, exces-
: sive wear, flat spots, scoring, or cracks. Replace the
complete assembly if any part exhibits these conditions.
