Dear Henk!

About 4 years ago the gearbox-overdrive unit of my XK 150 fhc was
rebuilt. There was obviously no need to remove the engine too. If
it is necessary for fitting the Guy Broad box I would ask them for
advice.

Best regards

I mean it is impossibel to seperate the gearbox from the motor in
the car. That is also what the manual says.
You have to remove the gear shift/boxlid before taking out the hole
unit. On a couple of pic�s, I will put in the photo album, you can
se where to place the hanging point.

Hello Henk
I have removed both 140 and 150 engines with overdrives. The easiest
way is to remove the units together however the engine & transmission
can be separated and the transmission can be removed from inside of the
car however I would not recommend it as it is more work than taking the
engine and transmission out together. To do it with the least effort I
would recommend that you use the following tool.

I got one of Mike’s pivot tools. Especially useful if you don’t have a high

Hi Skip
When I got my car from California, the tunnel and the body around
the clutch was cut up. My guess was, that some american blacksmith
had tried to remove the gearbox from the inside, and succeeded.
The fork was welded to the operating shaft, the blacksmith again !
So, you are right. It can be done. It�s a matter of taste.

I also have a 150 from California on the lift with the exact same cuts,
it appears that out blacksmiths went to the same tech school for
training. I have since ordered all of the parts for replacement. It is
possible to remove the non overdrive transmissions without removing the
engine as we did this on a 120 about six months ago.

Hi,

interesting postings regarding engine-gearbox-overdrive removal. As
I mentioned in my posting regarding this problem, removing of the
engine-gearbox-overdrive block was obviously not necessary to
overhaule the gearbox/overdrive on my 150 fhc. The gearbox, but not
the gearbox-overdrive unit can be removed from the car without
removing the engine - says the manual. Can I separate the overdrive
first and than the gearbox? I will ask the mechanic who did the job
on my car!

Best regards

Skip and Bernhard
Very funny. Over here we call jobs like this ‘‘american repairs’’
A lot of cars here in Denmark come from USA, and we have seen it
all. OK, now we are near the truth.
To seperate the to boxes is not possibel. You can unbolt it, but
the main axel is so long, that there is not enough space to draw
the OD out. I have not tryed, but am quite sure. It is up to you
to send for the blacksmith.

Removing the O/D and gear box IS possible w/engine in car, BUT, the
engine must be unbolted and moved forward(unless you cut out the
trans tunnel behind O/D unit to gain clearance). I remove the O/D
first on my 140, then the gearbox, but the engine was stripped down
to the bare block and moved as far forward as it would go. I doubt
doing that much engine-stripping work would be worth the effort
just to avoid pulling the engine/gearbox as a unit. Since my engine
had to come apart anyway, and since I did not have access to a
hoist, I completely stripped the engine in situ, and eventually
pulled everything out from underneath(O/D, then tranny, then
block). Also, my car has no interior to worry about soiling.–

Clutch removal:
I acquired a car that raced on Ormand beach Fla. in 56,57 blew up
and was put in storage for 45+ yrs. This car had a section of
removable trans tunnel attached. I was told by a 80 year old Jag.
racer/mechanic. that this was common procedure to remove the trans
with OD to get to the clutch in xk’s.

There is an amusing story on Norman Dewis’ book about it
cutting a whole out of the floor of a Mk1 to get to the box
ready for a race in Belgium. Once he got back to Coventry
someone pointed out that the floor was a structural member
and really wasn’t supposed to have big whole hacked it.
Still the car won the race and stayed in one piece.–

Floor structure/hot seat???
If you have ever restored an XK you will find the floor is bolted
to and sits on the frame in several places. If you were to take the
the top of the trans cover completly out the seats mignt sag on to
the mufflers. This would have no efect on the cars handling; except
your back end would cook.

Yes, Mark 1s were incredibly overbuilt cars. Jaguar had no idea how strong a
monocoque needed to be and they didn’t take any chances. The much airier
Mark 2s were the result of their experience.

I’ve heard that in the sixties and seventies many a Mark 1 met its demise in
banger racing (a full contact race with a demolition derby tacked on at the
end for good measure) because of their strength.

Didn’t they have to weaken the Mk10 monocoque to get it
through some later safety regs when people started to
realise that a little bit of deformation would absorb a lot
of energy and reduce the deceleration on the occupants.–
