[Healeys] Mating the overdrive to the transmission

[Hank Leach]

Agree with Michael- dummy or old mainshaft is essential to line up
innards then if cam is correctly placed-facing rear, and plunger is
tied back, units go together easily by a slight wiggle of 1st motion
(in gear) and tailshaft first insuring that the 8 springs are all on
their pegs-easy huh? Its about procedure. Article Im composing on
overdrive will be in upcoming AH Mag. Hank

 Although one may be difficult to find there is no substitute for a
spare gearbox 3rd motion shaft for this job. The spare shaft is used
to align all the internals then, using my special tool to hold the
pump plunger retracted

 You can wiggle it around with a long screwdriver, or use a suitable
'drift' to center it. Your best bet is to sit the O/D on end and lower
the gearbox onto it; gently rotating the gearbox while lowering. First
time I did this I must have got lucky, but danged if I can explain
this (see attached photo). Most recently I fought for a couple days
then threw in the towel and took gearbox and O/D to BCS which,
fortunately, is only a half-hour away. David and his mechanics had a
novel technique I've not heard described anywhere; basically, he
removed the pump completely--it's only two screws IIRC--and split the
O/D into front and rear sections and tipped the gearbox and O/D
up--gearbox on bottom--then had two of his mechanics pull the sections
together with huge channellock pliers while David rotated the output
shaft to 'feel it in' (you had to be there).

 Good luck. Make triply sure you have the pump cam oriented correctly,
or you'll get more experience with this process than you probably
want.

   I spent the day assisting a friend trying to mate his OD to his
transmission. The car is a '63 BJ7. The overdrive & Trans. were pulled
to replace a few internal trans parts which was done & we did not run
into any issues. We can get the OD to within approx. 1/2-3/4" of
mating to the trans, but cannot close that gap. We have confirmed that
the oil pump roller has been fully retracted. What are we bumping up
against & how do we get past it? Gary Hodson
