Type 9 gear ratios and part numbers
Hi,
I have been looking for ages and can't find the info I need. Does anyone have a list of type 9 gearbox part numbers along with which ratios they
contain and which model/vehicle they were fitted to?
I know the 2.8 capri gearbox had the better ratios but i believe there were also some 4 cyl sierras with the same ratios?
Thanks
Marcus

not hundred percent sure but i was always led to belive all type 9 boxes were all same ratio
just the diff ratio they changed to alter gearing
some people dream of sucsess, others just get on and do it !!

1st 3.65
2nd 1.97
3rd 1.37
4th 1
(5th) 0.82
This is for a std type9 and not a V6 ( 2.8)
it came from the speed calculator spreadsheet that can be found somewhere on here. The V6 has alonger 1st ratio IIRC that is the only difference I
think.

If it looks wrong it probably is wrong.

Hi,
Thanks for the replies. I have looked at the spreadsheet and there are 2 different sierra type 9 boxes on there.
The problem with a V6 one is that it has a long shaft and a different bellhousing. Wouldn't this push the gearstick back further or am I
wrong?
Thanks

It wouldn't fit, the bell housing for the V6 engines is different to the 4 pots AFAIK.
You can use a spacer like Caterham did to move the box back, which will move the gear lever back a bit.
You can also cut down the input shaft of long shaft box to make it fit a 4 pot engine though, but you will need to re-make the spigot bearing surface
on the end.

Oh... I see. Thanks for that. Looks like I will have some machining to do then.
