Ford 4-speed box, how to recognize straight cut or not?
alfas - 27/3/16 at 09:10 AM

i have no history of my recently purchased sylva, besides it was built begining 90ies & solely used for racing for about 3 years, than put into storage. so the car has practically no mileage.

ford x/flow engine with 4-sped box.

the box has an alloy bellhousing, so its a 4-speed box with removeable / separate bellhousing.
from the gearstick-travel it feels like a very precise quickshift, but the gearlever looks like the standard ford-lever with plastic pivot point.

when i first drove the car i was a bit shocked about the noise:

1st , 2nd, 3rd gear are wining like a helicopter, in 4th the box is quiet.

does the wining mean:

1. box is shot
2. box has straight cut gears fitted

have not changed nor checked oil yet.

Take the top off and have a look?

ok...thats what i wanted to do anyway for checking oil-level and improve breathing.

as the box is rather far inside the tunnel can i see the gears straight away?

Yeah if you have access and can take the top off the gears are right in front of you.

You used to be able to get a quick shift kit that used a screw on spacer under the gear lever and retained the standard Ford gear lever. All you were doing was moving the pivot point and changing the leverage.

4th straight through so will be quiet in any case.

I have a 4 speed with quaife internals, and it is exactly as you describe. Loud in 1-3 and quiet in 4. If you take the lid off you can see the straight cut gears.

i know that....but the lever is un-modified, even gearchange is like the typical quickshift....so thats another unusual feature on that box.

Not got a kit like this under the standard lever?

If you take the lid off a Cortina MK2 2000e style box the detent springs and balls are liable to go awol.

These boxes come in 2 basic casing types -- either with a bolt on remote (really an evolution of the 105e Anglia box) or the later built in remote also used in the MK1 Mexico
The lever on both of these types felt a lot more precise than the Sierra goobox.

ok...toda i removed the cover...below 2 pictures what i found (can anybody indetify what is written on the cover?)

Single rail Type E 4 speed with a straight cut gearset. Not sure what the writing is on the cover though.


alfas - 28/3/16 at 06:32 PM

perfect---thanks for the reply....straight cut....wow...quite happy....
watchign the pic closer, concerns me a bit:

the rear gear seems to have a strange shape, looks like a "valley" in the centre...is this wear or is the gear shaped like that?

Designed like that I believe so the selector mechanism clears the gear.

One mod we would do to the race cars would be to wire lock the roll pin in the selector quadrant. (The pear shaped part in your photo.) Put a couple of turns of locking wire through the pin and twist the ends together. Make sure it doesn't foul on anything or hamper the gear selection operation.

These roll pins have been known to break with shall we say "ambitious shifting" and the wire stops the bits falling into the gearbox.

another good news!!!! perfect!!

iŽll try getting access to wire the pin...not easy i guess, as gearbox sits very far inside the car....
