[DaimLan] Manual Gearbox Conversion Daimler V8 250


(Mike Viney) #1

Can anyone provide information on who might provide adapters/kits
etc to fit a manual gearbox to my automatic V8 250.

I think I recall that Toyota or Ford boxes have beeen used on the
daimler SP250 but know nothing about the saloon cars. I happen to
have a 4 speed box with overdrive taken from a Jag Mk2 and wondered
if this was the box used in the very few manual Daimler V8 250s
that were produced.

Alternatively has anyone just put in a small bock Ford/Chevy V8
with manual box.

Many thanks,

Mike–

Mike: I have a Daimler 2.5 V8 with auto box and a V8 250 with manual
overdrive. The transmission is basically the same as what would be in a Jaguar
MK2; however, the
top covers are different in order to move the shifter backwards (to
accomodate Jaguar’s moving of the V8 engine forward in the engine bay). Thus, you
will need the top cover and a suitable bell housing.
The engine and trans are currently out of my car, so I can help you
with photos and measurements of the components if that is of any help.
Like the V8, XKs require that the transmission top cover
locate the shifter about 6" back as well. A friend modified an all-syncro
Jaguar
transmission for use in an XK140. I can send you photos of his conversion,
but that is all I have-- photos, but I think they are self-explanatory.
Both of my Daimlers are pretty uncommon, as they are both left hand
drive with wire
wheels.

Bob, David,

Thank you for your responses.

I’ll see how difficult it will be to get a bell housing to suit my
jaguar mk2 box and an extended gear change lever housing. I suspect
it might be very difficult.

Thanks for the links to AUs/Nz which I am now looking at with
interest.

So a good bit more research to do before jumping.

Thanks again, Mike–

As far as a top cover, they are quite uncommon. Of course, the top covers
from an XK 120/140/150 will not work, as those are all Moss boxes. The top
cover from an XJ6 Series
1,2 or 3 might work, as those cars used the all-syncro Jag transmission
until Jaguar started using the 5 speed Gertrag? units, but suspect that top
cover would be hard to find as well.

Could you make one with a BW 35 belhousing and the backend of a Jag one?–

I am going to recommend you try this Daimler forum which probably
has all the answers you need on the Daimler V8. The Kiwi’s have
been very resourceful with gearbox conversions for the Daimler V8.
I have a Daimler SP250 fitted with the saloon engine and the manual
gearbox with over-drive. If you look at the SNG Barratt catalogue
for the Jaguar MK2 you will be able to work out a little more about
the gearbox specifics. For example the clutch in the V8 is smaller
than the larger Jag MK2 engined cars.

Gordon,

Thanks for the link and a very nice site it is.

From various posts it seems that David Manners does/did
bellhousings for the Jag Gearbox to daimler engine.

I will be in contact with them tomorrow and see what they have to
say.

Update

Got a price for the Toyota Supra gearbox conversion kit from
Conversion Components NZ at approx �2000 excluding gearbox but
including shipping import duty VAT etc.

I am now swinging towards using the Jag MK2 MOD gearbox I already
have. David Manners has bell housings at �195 but no clutch fork
for the V8 engine. They have been trying to source them but without
success. So that is something to be made. They also had no idea
about anything other things that need to be sorted. Gear change top
cover, mounts, etc They have flywheels at about�200

I can make a clutch fork, do any amount of cutting , welding,
fabricating for the gearbox tunnel and mounts.

From the parts book it looks as if the pedal box housing is the
same for auto and manual cars. So it seems new pedals, shaft and
clutch master cylinder is all that is needed there.

So I am left with the gear change to sort out to get the right
positioning of the gear lever.

Any thoughts, comments on this approach most welcome.–

Am I right thinking you are in the US?
Can you contact me offline and I might be able to help you out some
more with regards to parts.

Thank you

Hi,

in case anyone would need one, I have one extra.
I had to buy the short top cover when completing the
manual-OD conversion started by the PO of my E-type S1 2+2.
That box was from a 420G, but any manual XJ6 would have the
same (until the Getrag in LHD S3 XJ)

So if someone goes the Jaguar 4-sp full synchro route and
buys a box with the wrong (short, like E-type, possibly MK2,
S-type) box with or without OD.

I will also add the pivot mechanism as that’s also different
and I had to buy one second hand for the E-type.
I love the result so much I later bought a manual OD XJ6C
with exactly same gears, OD and final drive.

The parts are in Finland, shipping does cost something, but
should not be too much if you need the parts.

Cheers,
Pekka T.–

Hi Pekka T,I’ve read with interest the comments on the V8 manual gearbox conversion? I also have an automatic 1969 V8250 and imagine the driving experience would be far more rewarding if it had a manual gearbox,however finding an original is one thing and then paying for it and the work involved has sofar always got the better of me.I also have a manual with overdrive gearbox which came out of a 75/76 series 2 XJ6 with clutch,flywheel etc-
Do you think it would be possible to use this gearbox in the Daimler? If I read your post correctly you have done similar with your automatic e-type. Regards Jakson.


(Pekka T.) #13

Hi Paul,

Sure, although I don’t know how much I have to offer. Basically there are two different gearboxes and at least four different bell housings. I have only worked on the later 4-speed all-synchro and believe that even a car that had the earlier Moss box can use the later gearbox. The earlier bell housing may need a slight modification to accept the later gearbox but if you start with a matching gearbox and bell housing it should be quite easy.

But of course I do not now know where you could get the right bell housing for the Daimler 2.5L V8, all XK engines have the same bolt pattern and only slight changes with the starter and flywheel setup/size. And all V12’s have another kind of bell housing with a different starter location.

So of course you could use a gearbox and O/D from an XJ6 but I have no idea what you would need to do to make the bell housing and clutch fit the Daimler V8 engine. Perhaps someone with more knowledge about the V8/250/MK2 models could tell? I think there must have been many Daimlers with manual gearboxes too so probably finding a gearbox/bell housing should not be totally impossible.

Cheers,

Hi Pekka t and thank-you for your swift response,it was only as I pressed the send button that I saw the post had been some six years earlier so Im thinking I should be greatfull for any response atall? However that’s helpfull to know the gearboxes are similar and could probably be made to fit with either the correct bellhousing or adaptor plate,as for the starter ring and starter motor I’m unsure given that the XJ6 used a large pre-engaged type and the V8 has an inertia type but I’m sure a compromise could be found.The Other thing was how the gear ratios may differ-the Jag being a low reving straight six tourqy engine and the Daimler being just about the opposite tho I have to say as long as it was a reasonable drive I’d be very happy just to enjoy the manual gearbox? Thanks again,Kind regards Paul.
