<html><body>You don't have to disassemble the OD to put in the 8 springs and cam-they are the last items to add prior to mating the units.. However, if you pulled out the mainshaft from it, and then moved it around it's a good chance that the thrust washers in the clutch area are out of alignment and that geartrain must be realigned before the unit will go tight. Don't force anything-best take it apart and check for issues then reassemble.<br><br><div class="reply-new-signature"></div><p>-----------------------------------------</p>From: "warthodson@aol.com" <warthodson@aol.com><br>To: "Hank Leach"<br>Cc: <br>Sent: Tuesday June 20 2023 10:54:02AM<br>Subject: Re: [Healeys] Mating the overdrive to the transmission<br><br>

<div>Be sure that the 8 (4 of each size) springs are correctly
placed or they will be coil bound and resist assembly. See photo.

<div dir="ltr">We do have a spare trans output shaft & we have
watched your video & made a wire tool to retract the pump plunger.
We have verified that the plunger is fully retracted & the splines

<div>Although one may be difficult to find there is no substitute

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).<br clear="none"><br clear="none">
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.<br clear="none"><br clear="none">

<div dir="ltr">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?</div>
