Need help identifying an unknown t50

[ditn]

So i have weird t50 i opend and i dont know which one it is :s
Doenst seem to be a trd one since

mine:


original


I counted the teeth and i have

teeth counterteeth
1 28 15
2 29 22
3 27 28
4 23 33
5 21 35

did a ratio test but forgot values

i think

first is 2.6
and then 1.5 1.3 1.1
fifth 1

i think
Also i think there are spacers on the counter gear?

Anyone that can help?

I can't help with who made it etc. but I can tell you that with a 4.778 final drive the ratios you quote will be almost perfect for rallying.
If you want to sell it then let me know !

cheers,
TC

I can tell you that fifth can not be 1.0, 4th is always and only one with 1:1 ratio.
5th can be more or less, more often less.

[ditn]

I know quaife made a fifth 1:1 gearset

Quaife ratios:

First Gear: 2.347:1
Second Gear: 1.733:1
Third Gear: 1.379:1
Fourth Gear: 1.144:1
Fifth Gear: 1.00:1

caterham/albins also i think

I know a bit more information now by asking arround
its a short ratio uk? gearset with 1ste straight teeth and other angled
i think all five are changed not sure,will recheck ratios tonight.

i have a rallycar and a 4.778 so for now i will hold on to it,i will you know if i would sell it.

Than it is 3.5 gearbox, with shift pattern 1-2-3-5-4.
4th used as 5th and 5th used as 4th.

given the teeth number:
1: 2.678
2: 1.826
3: 1.384
4: 1.000
5: 0.861
So, only the first and the second gears have been modified.
And by the look of it, especially the straight cut on the first gear, I would say that this is not from a kit.

[ditn]

Yep thats correct,did ratios today and i cam to the same result +-
thanks for calculations.
Guess they were made locally somewhere which means i can make a spare set if needed

Nope wrong, it means you can get a set made for me ! lol !

[ditn]

i have no idea how much they will charge for 4 gears,depends on material i think.
Could make one then for you also.

But first i need to know what is different,do you think the syncromesh bearing etc etc would be normal.
So
1ste and counter
2nd and counter
would be needed to be made

Looking at the fsm it seems that the counter gear comes as one complete unit.
Maybe that is the reason for the spacers on yours, can you change idividual gears on the counter shaft ?
