Gear Box Mount
richyo - 23/3/04 at 02:40 PM
The premade chassis I have has the g/box mounts in the wrong place to suit the 4 speed box I have.
My query is : Can I make up suitable sized plates and BOLT them to the chassis as I can't weld worth a s**t.
Another query is is a Type 9 box longer than the standard 4 speed in relation to the mounting point. I don't want to go down that route as I
bought a new clutch for the 4 speed and I don't have a Type 9 box.
Sorry for rabbiting on, thanks in anticipation

I'd think bolting the mount is fine done correctly, as this is how it is attached to the donor.
Might be wrong tho (as always)

It may be worth getting a type 9 as the gear lever will be in the right place, and you will have the advantage of a 5th gear

I hope this helps.
A lot depends what you mean by standard 4 speed ---
The Sierra 5 speed box is quite a lot bigger than the Escort 4 speed box, but is the same size as the larger of the 2 types Sierra 4 speed box.
The older Cortina/Capri/Early Sierra boxes are roughly the same length as the type 9 but much more compact width wise and have a much neater
bellhousing.
See another thread for drawing by me giving dimensions of the 5 speed.
Clutches I don't know what engine you have.
As for clutches to mate a Sierra 5 speed box to a crosslflow with a 7.5" clutch all you need is a Hillman Avenger driven plate -- the Avenger
pressure has the same part number as the Cortina/Escort.

Notes on attached drawing

Simple Chassis Mount for Sierra Type 9
On my car I gave the drivers side section of the tunnel a dog leg to allow the type
9 box to fit while still allowing some room for the driver. The tunnel shown on the sketch
is based on a standard chassis and may need changes to suit.
Don’t scale off the drawing it is just a rough sketch to show the idea, on my car the tail
end of the gearbox fell in line with member B2.
Escort, Cortina/Capri and old MK2 2000e gearboxes have mounts in different positions
from the Type 9.
The mount design involves bolting through a 25x25 rhs --- use tubular spacers on the inside of
tube to prevent it being crushed and use large washer.
