[Triumph vitesse overdrive gearbox]

It definitely got the coarse spline it running on clutch from the original non overdrive box

 

[Triumph vitesse overdrive gearbox]

Okay thanks

when I fitted three rail j type  that was tight enough to fit 

so d type shortest box

then j type three rail   1 inch longer then d type

so single rail j type  2 inch longer then d type is that due to adaptor plate

 

[Triumph vitesse overdrive gearbox]

Hello

i have a three rail j type overdrive fitted in my vitesse

a single rail j type overdrive as come up for sale which I hear is stronger box ,

are both g/box the same length ?

I know about bellhousing  issue have a spare one to swap over  need to drill hole and find away of capping off we’re shaft comes through ,

is there any other fitting issues

[Vitesse mk2 fitting gt6 overdrive]

I understanding what ur saying

but how much movement  should there be on propshaft 

I would get prop on   But movement would be limited to 1.5 mm

would that cause further problems

[Vitesse mk2 fitting gt6 overdrive]

Went and remeasure diff to g/ box  output flange 43 1/4 tightest point

rimmers  output flange 53mm I reckon that the one I got

the one ebay   45mm 

1.5 MM of play bit tight

the one in picture of spitfire mk4 flange I reckon would work

must have done various size flanges

 

[Vitesse mk2 fitting gt6 overdrive]

Yes canleys said they use put on mk4 spotfire j type output flange run out of stock, 

If i cant find flange

shorten prop

Or new custom prop

Now going to remeasure has figures dont add up, 

G/box 4inch longer

Prop 43  1/2

Takes up 3 1/2

Difference 1/2 by all known facts

Have a look on eBay for 160286 flange. This is the part number for j type OD item but you would need to check with vendor that is actually shorter than what you already have...... 

 

[Vitesse mk2 fitting gt6 overdrive]

Well spoke to usual suppliers no good 

canleys said about mk4 spitfire had j type overdrive and short output flange

or shorten prop , look at original g/ box output flange but the internal diameter looks smaller 

it has piece weld on I think it call a oil throw which might  have to be cut off ,

well if I knew were to get short flange from I would, and more room to fit back together 

but try today no luck, so my only solution at moment shorten prop

were here

 

 

 

 

[Vitesse mk2 fitting gt6 overdrive]

Okay can’t source parts needed shorter output flange

only one option shorten prop

ok number stamped on gearbox  K F 12530

Please let us know if it works as these things are good to know🤓

hello see  what u mean  ,I was thinking maybe not enough clearance on  mainshaft  but looking at pics 

this could resolve it

Very last GT6 had the J type I think, Same as last few Mk4 Spitfire got them.

there are 2 different rear flanges available, 1 an inch longer. Also 2 different size OD to gearbox plates, again an inch longer.

i think you got the longer rear flange if you got the shorter adaptor on an 1850, but if you fit the short flange to the short adaptor the normal OD prop will fit. Certainly did on my Spitfire.

Ok thanks

[Vitesse mk2 fitting gt6 overdrive]

Ok thanks I will try that tomorrow 

[Vitesse mk2 fitting gt6 overdrive]

Hello 

the d mounting plate doesn’t fit

also the Propshaft  measure 43 half inch  fully in to tight to fit

so checking  overdrive definitely j type

so now need j mounting plate

also j propshaft  which is shorter  I hope 

or have to get propshaft cut

only glad had propshaft only  bought d mounting plate

[Vitesse mk2 fitting gt6 overdrive]

Hello 

here some pics of overdrive 

hope someone can identify it

[Vitesse mk2 fitting gt6 overdrive]

If you had said an inch longer, I would have said you have the long rear flange on a J-type or a single rail box from an 1850

 

Hello 

I identify box as gt6 73 us spec

basically 10 cm longer  then original non overdrive 

now can any overdrive be bolted on see numbers but know J ,D or A type not j 

solenoid on left hand side of gearbox

can u identify by numbers 

thanks joe

[Vitesse mk2 fitting gt6 overdrive]

Yes changed mounting plate and rubber mount and angle drive for speedo

only one concern with box it a 73 us spec don’t know any difference  and

 overdrive solenoid on left hand side of car 

had a propshaft what measures up ok but flanges both end smaller  don’t know if interchange flanges with original 

overdrive s/w just mount s/w under dash to test then make a decision

GT6 and vitesse overdrive boxes are identical (OK, some differences over the years and the last GT6 boxes were probably the best)

But it means you just need the overdrive vitesse parts. So a vitesse overdrive prop (different to GT6) likewise vitesse overdrive cabe, and assume you have the angle drive for the cable?

You must have the correct od rubber mount plus the overdrive mounting plate? And not sure what you are doing about switch, either the vitesse/early gt6 coulm switch, or the GT6 gearstick and switch depends on what is available and preference.

My only concerns is that you have a proper vitesse/gt6 gearbox. It has the same gearchange mechanism as the one you took out? I hope so....

 

[Vitesse mk2 fitting gt6 overdrive]

Hello in the process of gt6 overdrive box to my vitesse mk2 ,now if I knew what I started

so  the main issue is gearbox approx 10cm longer had

 to cut propshaft tunnel back and possible trim sides slightly 

to get gearbox in  but now in  Now next issue is propshaft 

Or all over drive props the same or have to modify original

or any issues I face  has anybody done this

thanks joe
