langer 5. Gang -> jetzt fehlt die Leistung, was tun??? | Posts 16+

The colleague actually made the change on the T4.

He probably replaced everything because he got a good deal on all of it.
That it's just the gears that are the problem is giving me some new ideas...

Thank you!

@ Blaubaer

I was recently on the train with the Trekker, and as far as I remember, the speed was 195 km/h (according to the speedometer) at 4600 rpm.
The CTN (presumably a car model) has a very short wheelbase, which meant that even the larger 195/60 14 tires couldn't really compensate for it.

"When I can drive again (I broke my collarbone), I'll run the test using VAGCOM and GPS."

Here are the part numbers for the 0.681 inch wheels:

Thank you.

In addition, I would like to emphasize that switching to a 0.68 ratio is only worthwhile for vehicles with increased performance! I completed the gear change last week, and it's not a huge deal, as long as you have the right tools and can easily remove the gears! You can also fill the gearbox oil through the opening for the speed sensor, which saves you the trouble of removing the intercooler on an Ibiza!

My standard Ibiza AFN has no problem with a tire size of 0.717, but I think that with a size of 0.68, it might be difficult without increasing the engine power! A size of 0.7 would probably be optimal for the 110 horsepower in the Ibiza.

Best, Boro.

Hello,

I wanted to add that, with the right jack, you can position the car at such an angle that you can avoid the hassle of changing the transmission fluid.

For none of the gear sets discussed here are any parts required other than the gears themselves.
The longest translation might be this one: 0.659 = 27/41; 02Z311158A; 02Z311361A.
"Nothing needs to be changed on the gear lever itself; only the coil spring/washer on the small gear is 1-2mm too large in diameter. This can be easily fixed in a minute using a grinding machine." The amount mentioned should be approximately correct for this translation as well.

Best regards, Frank.

Would this also work as easily on a Golf IV? Or is the 5th gear located somewhere else in the transmission? In my car, too, the maximum speed is 210 km/h and the engine speed is 4600 rpm (going downhill). Above all, it would operate in a more comfortable RPM range when traveling at normal speeds.
The research indicates that converting to a 6-speed transmission is very complex (clutch, drive shafts, etc.), so I think a longer 5th gear would be a better option. A more sensible approach.

Does anyone have any tips or ideas?


Regards,
Frank.

Then, please check your service booklet and post the transmission code letter.
It is located right next to the "AHF".

Then, "you can be helped" ...

Wow, that was fast...
GKB is DEA. Thank you in advance for your reply!

Here's the translation:

"After that, DEA 0.77 is translated."

I would therefore not immediately go to 0.681, otherwise you will have a 6-speed gearbox without a 5th http://www.dieselschrauber.de/GKB.html.

Well, my question was also whether it's just as easy to do. Basically, you take the cover off, change the gears, and you're done (in a simplified way). And secondly: Which gears fit? Or are the shaft spacings the same across different gearboxes, so that the above-mentioned... Do the part numbers match?

The aforementioned gear changes all refer to 02A transmissions. I also can't say whether it's equally straightforward with other models!

Good morning.

after that, DEA 0.77 is translated. It sounds quite short at first, but the axle ratio is longer.

The axle ratios of the (diesel) transmissions in the fourth-generation Golf are all SHORTER than those in the third-generation.

@Occasional_Tinkerer

The described gear change and part numbers also fit the (02J) transmissions in the fourth-generation Golf. However, when choosing the gear ratio, you should really consider that the longer the ratio, the worse the transition from fourth to fifth gear will be, and the slower the acceleration will be in fifth gear. Possible translations are, for example: 0.756, 0.717, 0.7, 0.681, 0.659.

Best regards, Frank.

You forgot the 0.744 from the CYP! I have a Zahrad couple just like this one!

I drive a Golf III AFN, slightly tuned, with approximately 130 horsepower. Last week, I also installed the longer 5th gear.

That's exactly what I want to do too.
Can anyone provide any information about the torsional strength of...?
0.681 couples say?

Sure, here's the translation:

"Additional question: What are the costs for TÜV registration?"

Regards,
Klaus.

@ Klaus

The 0.681 pair will become as strong as the others. Here's the translation:

"This part is from a 02B transmission, which came from a T4 vehicle."

TÜV - forget about it. By the time an inspector understands what you've done, they've probably already stopped the car. And how do you plan to provide a complete exhaust emissions report, aside from the higher maximum speed?

My motto is: either install it and don't tell anyone, or just leave it alone.

@Opportunity

The wheel hubs of the 5th generation (presumably of a specific component) were already installed in the Vento, so the replacement should be a straightforward process. I can take a look at an EBF in the 01 ASV in about 2 hours and see if it looks similar to my CTN.

m;

Okay, great, it seems like it fits. I have no idea which translation would be appropriate.

"Hey Frank, I think 0.717 or 0.7 would be the most sensible alternatives (I used a gear calculator, and with those values, you'd get 225 or 230 km/h at 4600 RPM instead of 210...)." What do you mean?

@Boro: Even 0.744 is still too short for my purposes. It wouldn't make much of a difference... But thank you anyway!

@dieselmartin: Have you taken a look at the EBF yet?


Regards,
Frank.

The EBF has the same lid and lid gasket.
Everything looks very similar.

I would say nothing is stopping your passion for tinkering and fixing things.
