Russell,
these trannies are extremely finicky about going back in. What
you're experiencing
is not uncommon at all.
The tolerance between the pilot bearing and the pilot shaft is very
tight. If the end of the
pilot shaft is good and the pilot bearing is new, and not boogered, and
you
are POSITIVE that the tranny is splined into the disc and the T/O
bearing
is on..............
here's what I would suggest, and the order I would personally try
them...............
1)
Be sure nothing has fallen down between the Eng. and the Tranny.
(wire harness, tranny vent hose, wire loom bracket, etc.)
2)
Be sure the trannies weight is supported on the front, and the trannies
weight
isn't being allowed to "hang" on the front end.
(support the weight on the bellhousing)
3)
Using a prybar, pry the tranny forward with a good bit of effort while
slightly
shaking the tranny. I use a 4ft prybar, prying against the top of the
tranny
where the shifter bolts to, using the area on the floorboard where the
shifter
bolts down to put the end of the pry bar. This applies the forward
push to the
tranny without causing an upward or downward force on the tranny.
(this technique works in most situations)
4)
AS A FINAL technique......install a couple of bolts in the two
uppermost holes
on each side of the bell and using a ratchet and extension, "draw" the
bellhousing
forward onto the engine. I use a 3ft extension on a 3/8 ratchet. You
will experience
some resistance as you draw the bolts down. Alternately tighten the
bolts, slowly
working the tranny forward. If at ANY TIME the bolts seem to "snug
up", give the tranny
a slight wiggle and try again. If the bolts seem to be
snug...STOP.....if the bellhousing
isn't flush with the engine, sorry......time to take er back out and be
sure alls well on
the pilot shaft, clutch disc., pilot bearing, etc..
Here's the deal........
if you used one of those plastic alignment tools to align the disc when
you installed
it, then that's likely the prob. It's off jest enough to cause your
problem, but doing
the above will "work" the disc into the right location to allow the
tranny to slip forward
with a bit of effort.
If you've allowed the weight of the tranny to "hang" after getting
tranny splined
into the clutch disc, then the disc may be way out of whack and you'll
likely have
to drop the tranny to realign everything.
You MUST have the tranny in gear in order to facilitate, make easier,
the installation.
If the tranny isn't in gear, the front shaft will tend to rotate a bit
causing a bit of difficulty
on "stabbing" the unit.
as a final note.....I run into this exact problem on MOST Yota's and
Nissans.
The tolerances are jest that good.
any whoooo........
try the above..things oughta work out okay.
hopefully what you needed,
