[Healeys] FW: Healey gearbox, rear end, driveshaft problems. MAYBE SOLVED?

[PG]

Hi Randy,

The input shaft has a bit of movement side to side...in fact, on facebook,
somebody posted a video showing this asking if it was normal.  I replaced my
input shaft bearing a couple of months ago and it might have removed some of
the play but it was definitely still there.   I think that the pilot bearing
in the crank shaft will control the wobble.

Regardless, replacing the bearing is a straightforward job so you have
nothing to loose.  That being said, I don't see how it would affect the
jamming of the forward gears.  I would agree with an earlier comment that it
is likely something to do with the shifting forks.   There is a detent pin
in the reverse fork (I think).....I wonder if that pin is stuck in the
recessed position allowing two forks to move at the same time???

On another note, not all BJ8 transmissions have the caged gear/shaft
bearings....only the later ones.  The earlier BJ8's use the needle bearings
so, you might want to check before you place your order.

Good luck,

Paul

Fellow Healeyoids,

OK,  I removed the gearbox with a little help from my wife last night and a
lot of Samuel Adams Imperial White Ale (10.3% Belgian Ale).  It appears that
the input bearing is really worn.  At the end of the 1st motion shaft it has
about a < inch of play.  That is about 1/8 side to side.  That seems like a
lot.  Unless this is minimized by the bushing in the flywheel.  I think that
I need a 1st motion shaft bearing.  I will order one from Moss tomorrow.
Along with the caged bearings for the 1st motion shaft.  It is a BJ8
gearbox, so it takes the caged bearings.  I hate to go through the entire
gearbox when it was just gone through but this seems like the problem.
Maybe the side to side motion of the 1st motion shaft was the clunking and
reason why the car would not go into drive.  Maybe more than one gear was
being engaged at a time with the wobbling of this shaft.  Does this seem
plausible?  Does this answer the problem as to why my car would go in
reverse, always, forward sometimes and give a loud randomized clunking while
idling in neutral?    I will likely build up my extra BJ7 gearbox as well.

Thanks!
