F10/13 gearbox's

[greg1.4]

just wondering what the difference is between the F10 SCCR and F13 SCCR gearbox's are?

I know the earlier Quiafe SCCR F10 boxes were easier to change the clutch but is that all?

[garyc]

The gearboxes are the same except the f13 has a bigger bellhousing to take a bigger clutch. All the internals are identical.

so what clutch do i use with a f10??

[andymac]

it will be a 190mm clutch you will use i believe the f13 you use a 200mm clutch

[craig green]

Nah, F20 is 200mm IIRC, F13 is 190mm. Either way an F10 will need a Nova 1.2/1.3 clutch.

i know on the corsa sport x14xe i have there ita a 200mm clutch on an f13 box but i also had a nova sri on a f13 box with a 190mm clutch

how can you tell what gearbox it is you have??? i take it the F13 and F10 are both 5-speed??

Its stamped on the casing in big letters under the dirt under the selector fork. It should also be stamped on the bottom of the end casing along with (C)lose or (W)ide ratio, and the final drive.

All F13's are 5-speed, F10's can be 5 or 4 speed. 5 speed ones look like this, and I've highlighted where the stamp is:

4 speeds have a different end casing, with a 36mm nut on the end that covers the input shaft:

They also have F10 or F13 cast on the top too, well usually!

F10 clutch is 190mm
f13 is 200


f20 is 226 iirc

f13 boxes had twin syncro ring hubs, the f10 didnt.
