Rob and myself took an F16 apart this evening.
Very interesting and I'll be photographing the internals for future reference.
Now, there are few questions on my mind.
1) The old F16-F20 debate. What exactly is different about them?
The F20 diff looks bigger.
The diff bearings look identical from what we've seen.
The clutch arm is larger on the F20, bigger diameter.
Are the internal bearings larger in the F20?
2) If I want to change the final drive ratio then I need to change the pinion on the output shaft and the diff gear.
Is it possible to remove all of the gears from the output shaft? It looks to me like the circlip comes off the end and then the gears can be pulled off?
Then I could fit the output shaft from another gearbox.
Someone said that the whole clustur has to be changed as one. Why is this so?
Funnily, my boss at work said that I should remove all of the synchros and make it into a dog box.
yeah the main shaft is attached to the pinion, so you have to change the lot..involves the gear swapping as i am sure you have noticed
internal bearings probably are different as the whole unit is a new thing (f16/f20 wise)
the main bearing is roughly the same size but is very different f16 to f20 so the main bearing and the plate that supports it need to come from the fd donor box.

Anyway, my theory of how to swap the final drives is correct then.
You remove the output shaft from the box with the required final drive, strip all the gears off, and then fit the gears from the box to be used. ie: just swap the output shaft with the pinon on and the diff gear.

i belive one of the bearings on the F16 box is infact bigger in diameter than that of the F20 box. DONT quote me on that though was it was late when we realised that an F16 (orF20) cluster wouldnt go into the others casing.
it was my box odders we stripped so kenny could have the fd as i buggered it. it kept jumping out of 5th and 3rd was noisy as one of the box casing bolts had sheared off deep inside the casting. keep dropping oil everywhere and as i used third the most it got noisy
