Toro 92801SL Rev I Groundsmaster 300 Series Groundsmaster 328 D Service Manual

PTO Drive Shaft Universal Joint Replacement (Fig. 16, 17)
1 Remove the P.T.O. drive shaft.
15. Grease the fitting SLOWLY until grease starts to
show at the seals. Use a low pressure hand grease gun
or a power gun equipped with a pressure relief valve.
Never use a high pressure gun without this adapter as
it is possible to blow the rollers out of the yokes with the
tremendous pressure; seals may also be damaged.
2. Separate the two sections of the P.T.O. shaft.
3. Mount the section to be repaired in a vise so that the
U-joint is pointing upward.
NOTE: If the splined portion is to be repaired, protect
the splines from vise damage with wooden blocks, vise
jaw cushions, etc.
16. Test the action of the assembled joint. It should move
throughout  its  range  without  binding.  If  a  slight  bind
exists, rap the yoke lugs with a soft hammer. This will
usually free the joint. If it does not, disassemble and
check for the source of the bind.
4. Use two thin screwdrivers to remove the “C” shaped
snap ring from each of the U-joint rollers (located inside
of each yoke). Remove the shaft from the vise.
IMPORTANT: When clamping in the vise, clamp the
solid  portion  of  the  U-joint.  If  the  yoke  must  be
clamped,  clamp   lightly.  Use  jaw  covers.   Avoid
clamping the tube portion of the propeller shaft as
it is thin and easily crushed. Never clamp the tube
portion, even lightly, when it is necessary to ham­
mer on the yoke. Support the free end of the propel­
ler  shaft  to  remove  some  of  the  strain  from  the
clamped end.
5. The vise may now be used as a press by placing a
small  socket  against  one  roller  and  a  large  socket
against the yoke on the opposite side. As the vise is
closed, the small socket will force the cross to push the
opposite roller partway into the large socket.
6. When the roller is forced partway out, grasp the roller
and strike the yoke to complete removal. Do not spill the
needle bearings.
7. Follow steps 5 and 6 to complete the removal of the
U-joint from the P.T.O. shaft.
8. When replacing the U-joint, pack the roller bearings
with   the  recommended    lubricant    (multi-purpose
grease). Pack carefully to eliminate trapped air. Install
seals.
9. Start one of the rollers in the yoke. Insert from the
bottom with the open side of the roller up to prevent loss
of the needles. Make sure that each roller contains all
of the needles.
Figure 16
10. Insert one of the cross trunnions into the roller. Start
the other roller making certain it slips over the trunnion.
11. When partially seated, place the two rollers between
the vise jaws. Squeeze until FLUSH with the yoke. Stop
when flush; do not over-tighten.
12.
Tap one of the rollers (use a brass punch the full
width of the roller) through the yoke until the snap ring
can be inserted. Insert the snap ring. Use new snap
rings. Make certain the snap ring is seated to full depth.
13. Support the cross and strike the yoke to force the
snap ring against the inner face of the yoke. Always seat
the roller in this fashion to prevent improper centering
of the cross.
Figure 17
14. Install the other snap ring or rings and seat the rollers
against the rings.
