Transit diff ratio
Bob C - 16/3/08 at 12:36 AM

Help, anybody in the know... My brother got a cheap but OK diesel transit chassis cab & he's very happy with it, except, the gearing is incredibly low! I've checked the diff & it's about 5.7:1. Is this for real???? It's the one with double wheels if you know what I mean, can't remember the reg, probably about 10 yrs old.
Anyway - anybody know what ratios might be locatable in scrappies - this thing is screaming its nuts off & won't get to 60...

Try putting it into 5th gear!

Chassis cab Transits often had a 5.8 ratio on a Twin wheel set up

You can replace with 5.1 or 4.63

there are no other ratios for the older twin wheel axle

like all Ford axles there may be a tag with the ratio bolted to the back plate, unless its rusted or missing etc.


hope this helps

the gearbox also has a lower than normal 1st

Look for the diff from the minibus variant as it uses the 4.6 ratio
I fitted one of these to a 190 high top which had a 5.1 fitted, but it pulled the 4.6 no problem (although it was the turbo engine)

Cheers
