Hullo! :wavey:

Was just mulling over in my mind. Is there anything significant stopping me from getting the longer ratio sixth gear "cog" from Skoda (or whoever) and installing it in the gearbox at the same time as my LSD goes in?

I just like the idea of having the normal shorter ratio gears up to 5th, and then only for cruising, having that nice long 6th gear. Would shifting from 5th to 6th be made awkward by the longer gap between the two? I assume as the gearbox is going to be on a workbench anyway, it won't be too tough to split it open and install the gear?

Anyone know the part number for the cog, and any other bits which would be recommended to replace in the process of fitting the higher ratio 6th speed cog?

81 views and no replies. Hmm, maybe I'm thinking of another thing else no else has actually tried before. From what I can tell the 6th gears are:

02M 311 349 L Change gear (6th) 34/45 (FJW,FSM)

02M 311 349 J Change gear (6th) 35/43 (HJS)

Can anyone read anything into this? I thought the long ratio box was a DRW code?

Can you not stick it on the end and have 7, Now that would be cool [and a First ]

I am looking into changing the final drive instead - I want the whole range of gears to go up instead as 1st/2nd are useless anyway

Not had time to investigate it much as yet though, so keeping an eye on this thread too

Its not the gears that are different, its the final drive for 4th 5th and 6th.

02M 311 349 L Change gear (6th) 34/45 (FJW,FSM)

02M 311 349 J Change gear (6th) 35/43 (HJS)

Mine's a short ratio (late '04) box with an HJS code, so I guess you would want the other one.

The deafening silence may be because we can all recall the dire warnings you get in Haynes manuals: touch one bit of a gearbox and you could upset the rest of it.

Refitting is reverse of removal

Remove Items A/B/C etc as described nowhere..

Remove the gear box and split is (see diagram 11.1 a)

:P

HTH

i cant really help you with that one jason, i've never seen the inside of a six speed unit before, but i have swapped gears on the five speed 085 units before....

in most cases you can remove the fifth gear without actually taking the gearbox out of the car, the fith gear is on the very end of the box and can usually be accessed by a cover or plate on the end of the box.... the fith gear has it's own syncromesh too which needs to come off, and the selector fork/mechanism too

34/45 = 0.75:1

35/43 = 0.81:1

did you get those numbers from etka/etos?? because those part numbers are just for a single gear, somewhere on another page thiere will be the other half of the gear listed, a single 'gear' is made up of two cogs hence two numbers for example (34/45).. basically these numbers tell you how many teeth are on each gear, so the sprocket on the first motion shaft would have 34 teeth and the sprocket on the output shaft would have 45 teeth..

it's also worth notig that not all of the listed gears will work properly, firstly because of clearance issues, secondly because of the amount of time it takes the syncromesh to equalize the speeds of the shafts, and thirdly because some cogs require different spacers to be fitted..

as i've said, i've never even seen a six speed unit, so ignore everything i say

Fitting bigger wheels/tyres would be another way to achieve this particular objective (the whole range of gears to go up) but obviously there would be limitations on how far you could go with this.

I wanna keep the speedo behaving itself

Yeah, I know !

I have no idea on cost yet either - I know it can be done for a lot of gearboxes etc but the Fabia one is back to front apparently (not sure) so could be less of them about ==> maybe no set available or it could be expensive.

all of the 6 speed boxes you dont catually need to take the gear sets out!!! you leave them in the end casing, and the diff stops in the bell housing side, so if you wanted to swap the 6th gear you would need to change the "matching gear set" (end gears off the shafts) and you would need to take the shafts completely out of the box!!! :eek: (reasonabley big job)

Hope this helps Jason

Cogs, cogs, cogs..... a cog is a wooden element of a windmill mechanism.

I think jabba_luke is correct, It could get expensive doing it this way, try larger wheels as this will have and effect on the over all drive. Touching the gearbos could have disasterous effects, they are made quite precise, so touching it may upset it.

Errr, but why would you swap the gears? The gears are identical in both boxs!!

The difference is with the final drives. The 'box has 2 final drives, one that serves 1st 2nd and 3rd - this is identical in both 'boxs. Its the final drive that serves 4th, 5th and 6th that varies between the 2 'boxs - NOT THE GEARS!!!!

Please do correct me if I'm wrong though! :P

You could be correct but from the boxes i have had apart to fit the diffs to, it looks like there is only 1 final drive (the big cog that is bolted to the diff) i could be wrong though

Jason said he is happy with all the other ratios but it is just the 6 gear he wants as a sort of "overdrive". im with you though with the sort of power and torque jason and i are pushing out i would rater have the whole box longer, as 1st and second are WAY too short!!!!

Not according to the data in this spreadsheet (put together a while back from data on here) - 4th, 5th, 6th and both final drive ratios changed between the long and short-legged Fabia vRS boxes.

@jabba_luke - that's exactly what I'm thinking, make all gears longer so I can perhaps use a bit of 1st and 2nd to accelerate with

Lemme know if you guys are looking into this though, would definitely be interested in a costing & trial

TBh realistically is there *any* difference to justify changing the box's from a late model to a early one? i mean lets face it, its not really as if economy is a issue here

Its just more of how you like to drive really if you have got lots of strait roads or wotorways it is nice to sit at 80 with the engine at 2000rpm rather than 2500rpm :P

plus for the people that have got quite abit of power, it helps with 0-60 times as there is less gear changes it also makes the car quicker overall in gears because of the more usable rev range!!! plus it heps with top speed *ahem* 162mph (gps) *clears throat*

Well, as I don't like making visits to 140+ a habit, I will be doing the hassle free thing and sticking with the normal box - It will have come from a pd160 cupra though.

Was thinking about this before.. on my way home.. watching the speedo n rpm

my car's sweetspot is "3 o clock" on the revcounter and speedo in 6th.

Been thinking myself a bit., Even the shorter ratio box will do about 155mph indicated before touching the redline. If my new map means it will be a revvy car capable of pushing beyond the redline in 6th, then I reckon if I ever want to go that quick, it won't matter which box I have, and "probably" having the revvier setup would actually be better than trying to do fast speeds down around 3500rpm.

having the revvier box will give you better acceleration
