your run a Marina, an Ital, or a Marina based kit
car, this kit has been created by Marina & Marlin owners for you.
unique feature of our design is that it allows you to take a Ford Type 9 V6 gearbox and with
our adaptor, bolt it onto the back of your Marina bellhousing - without
altering the Marina clutch mechanism!
it a complete bolt on and drive-away kit?
- although we can now supply a modified long input shaft gearbox,
crossmember and modified Marina bellhousing, it will still require you
to provide the propshaft and speedo cable. Enquire for costs.
still happy to sell just the adaptor plate if you want to
arrange for the rest yourself; this way you can put a
package together to suit your own car and your own budget. You supply the gearbox, altered
propshaft, gearbox mount and speedo cable - you might want to use all
new or reconditioned parts, you might want to use a gearbox already
laying in the back of your garage or in a car in your local scrap yard -
your car - your budget - your choice.
come you can use the Marina clutch?
1.8 & 1.7 Marina and Ford Type 9 gearboxes share two key common dimensions, a 25.4mm (1
inch ) diameter input shaft and 23 splines on the shaft for the clutch
use the Ford Type 9 V6 gearbox and not the 4 cylinder gearbox?
The Marina bellhousing
is unusually deep compared to many others, this meant that BL
specified Marina gearboxes with long input shafts. The Marina
input shaft is longer than the standard
four cylinder Ford Sierra or Capri Type 9 input shaft, leaving no
space for our adaptor plate. The adaptor plate places the splined
section of the standard Ford gearbox too far away from the clutch
plate, so the
standard Ford 'box will not fit without modifying the Marina clutch cover and replacing the clutch
plate, it was something we didn't want to have to include in a kit, as it
would increase the cost. The Type 9 V6 input shaft is longer
than the Marinas', which means we can position the splines in exactly
the right place to match the Marina clutch, with the excess taken up
by the adaptor plate (depending on your engine,
you may need to trim the end of the input shaft slightly). What
we wanted was a spec which minimized engineering and maximized
'bolt-ability' straight out of the box.
- the latest information that we have from a reputable gearbox company
is that it is possible to retro fit a V6 input shaft into a "4
cylinder" short shaft gearbox; so for those of you with a short
shaft 'box in the back of the garage, you could have this done as part
of a rebuild.
Here's a picture of what you
need - the difference between a 4 cylinder and 6 cylinder version is
that the helical gear at the rear (shown) has 18 teeth in a 4
cylinder gearbox and 19 teeth in a 6 cylinder 'box. The 2.3 V6
gearbox has 18 teeth like the 4 cylinder version, but has
the same longer shaft as the 6 cylinder version creating a
cross-over input shaft.
The input shaft can be bought
from BearingKits on
Ebay or by
telephoning direct on 012 7979 3631.
We recommend that you speak to your local gearbox company for more
details on fitting the shaft.

I have to get any machining done?
- There are some V6 Ford Type 9 gearboxes with an extra plate bolted
on the front of the gearbox face to secure an internal stub bearing for
the layshaft, our
adaptor kit is not designed to accept this version. Itís
relatively rare type and unsuitable as the cut out for the housing prevents
the use of the lower gearbox/bell fixing necessary for extra weight of
If the front of the
gearbox that you are looking at is like the one shown in our Technical
Gallery on the left of this page you will be fine. For a picture of

Marina engines can I use?
1.8 'B' series, 1.7 or 2.0 'O' series engines and all A series and A
plus Marina/Ital engines.
1.8, 1.7 & 2.0 litre conversions require no changes to the
Marina/Ital clutch mechanism. An 'A' series / A+ conversion will
require the use of a 1.8/1.7 Marina clutch plate and some extra
machining on the inside of the clutch release bearing carrier
to fit the Sierra input shaft sleeve, or the use of a 1.8/1.7 clutch
release bearing carrier.
