I am not sure if my method will work exactly the same on your TR4 as it has
worked many, many times on my TR3s. But this is what I have done in the
past. After removing all of the interior so that I can get to the
transmission, I remove all of the securing bolts on the rear transmission
mount, the speedo cable, clutch slave and the drive line. Then with my floor
jack and a suitable piece of lumber under the oil pan, I slowly raise the
engine and transmission. I stop lifting when the top row of studs/bolts that
hold the transmission and engine together, are just above the edge of the
fire wall by maybe a 1/4 inch or less. Then I place a piece(s) of suitable
wood 'dunnage' between the cylinder head and the firewall so that the wood
rests on the throttle shaft that runs behind the engine. Be careful here, as
you can bend the throttle shaft in the next step! I fill the available
space so that when I release the jack and the engine settles back down, the
cylinder head will rest against the wood such that it is supported by the
fire wall. At this point you should be able to easily remove the studs/bolts
that hold the transmission and engine together and remove it fairly easily
by yourself if needed, although a second set of hands comes in handy.
In the TR3s I used a 2 X 4 and a piece of 1/4 inch thick plywood. You may
have to get creative in the TR4 to arrive at the correct thickness and
length of the dunnage!
I have left the wood dunnage supporting the engine in the TR3 for several
weeks waiting for the transmission to be rebuilt, with no problems.
As always, YMMV and good luck!!

Subject: Engine Support during Transmission Removal
Greetings, Everyone,
I haven't posted in some time as it's been happy motoring with my '62 TR4.
Yesterday, however, just a mile or two from home, my gearbox started making
a
loud 'whirring' noise in third gear. Just third gear.
I'm guessing a bearing failed. Perhaps it's this infamous 'tophat' bearing
I've
heard of.
As fate would have it, I secured a 4-speed gearbox just a couple of months
ago
to swap in while my OD gearbox goes to spend some quality time with our
local
TR gearbox guru. I guess that's going to happen NOW.
Here's my question: What is the best means of supporting the engine while
swapping the gearbox in and out. I've just used a jack in the past when
replacing my flywheel assembly, but then the car can't be moved that way.
I'm assuming I can just 'pop' the other gearbox in, but on occasion I have
witnessed that the best-laid plans of mice and men often go awry. So in case
of
the unlikely event my plans don't work out.....
Has anyone out there devised a clever method of supporting the engine while
the
gearbox is out that allows the car to be rolled around?
I was thinking of some sort of 2x4 thing going across the two flat spots on
either side of the firewall and some webbing. Before I reinvent the wheel, I
figured I'd poll the collective wisdom of the list.
Thanks in advance,
-jeffrey
