Hi,

I'm the owner of a Skoda Fabia 1.2L, 3 cylinders from 2005.

 

I'm busy replacing the clutch, and according to the manual I had to first drain the gearbox oil before removing the gearbox.

First I opened the inspection plug, which resulted in some oil leaking out of it (brown color).

I had some troubles finding the drain plug. Evetually I opened a screw which I thought was the correct one (Circled red in the attached file). To my surprise there came very little oil out of it, about 300ml. The oil was very clean and smelled different than the oil coming out of the inspection plug.

Afterwards I kept looking and found another plug (Circled in the attached file, Allen key 17). When I opened this one, a lot of oil came out (>1 liter) which looked the same as the oil coming out of the inspection plug.

 

It looks like the first screw I opened was the wrong one. Does anybody know what is the function of this screw and how to get the gearbox back to it's original situation again?

The gearbox type is 02T. Some technical information about the 02T can also help (Couldn't find so much on internet).

 

Thank you very much,

Yossi

Well you found the drain plug (17mm, below left driveshaft), can't you just put the other screw back in and carry on?

 

For 7 Euros + tax you can download a whole repair manual for 02T in Fabia from erWin Skoda, the genuine workshop instructions. Let me know if you need help finding this.

No need to drain the oil anyway

Wino : I could refill the oil and go on, but I will miss the oil which came out when I opened the wrong screw. I would like to know which oil has to go in there, how and how much. It seemed different than the normal gearbox oil.

Thanks for the tip about the repair manual. I'll have a look.

 

Techle : I was afraid so...but I just followed the Haynes workshop manual which says it needs to be done. Now I regret it.

 

There's only gearbox oil in there, nothing else.

Draining the oil does make life easier cos you can then remove a drive flange to give a bit more wriggle room to get the box out.

I drained on my first time, didn't for my recent one.

True, however I remove the flange with the oil in, minimal loss as the level is normally lower than the output level anyway.

 

That said there would be no negative effects from replacing the oil, it's not a bad idea to anyway. 2 litres will fill no problems.

I guess so, especially if the car is on a lift, and level, rather than on a driveway with just the front end up.

Where are you @yos, and what facilities do you have for this job?

Unfortunately I don't have a lift, but when refilling I could raise the car a few centimeters while still being leveled

In reply to the earlier question the screw you have removed is for the reverse gear mech/idler.

The info on erWin Skoda can mostly be found for free at workshop-manuals.com though you have to put up with page by page loading and adverts, begging pop-ups etc.

As far as I can tell from a quick look, the screw you undid is described as 'screw for reverse shaft support' (as said above, while I was typing), item 19 on this page: https://workshop-manuals.com/skoda/fabia-mk1/power_transmission/gearbox_02t/gearbox_mechanicsoperation_constructiondiff./disassembling_and_assembling_the_gearbox/iii_disassembling_and_assembling_the_drive_shaft_output_shaft_differential_and_gearshift_forks/

 

The torque (plus angle) figure for doing it back up is given there, I think yours looks like M8?  

 

If you navigate through the menu on the left, you can probably find various other useful bits of info.  I find it much easier to spend a little cash and get it all in pdf form via erWin though.  Get lots of other stuff while you're on there if you do decide to go that way: engine-related, chassis-related, self-study programmes, wiring diagrams, you name it.

Thank you very much Wino and Techle for the links and files !

It seems indeed that I've opened the reverse gear screw. In the diagrams it looks as if the gearbox is one space so you should expect the oil coming out of this screw to be the same one as out of the drain plug.

How can it be that the oil coming out of this reverse gear screw was different? It was very clean and smelt different. The car already did 200,000 km  so I expect the oil inside the gearbox to be everywhere the same...

It's a mystery to me.

Me too, there is only one oil inside the gearbox, just draining from a different area, It is conceivable that 'dirtier' oil collects lower down.  

Would you suggest that I just fill the gearbox with the normal oil through the filling plug?

With the appropriate oil yes.

I'm going to follow your advise. Thanks!

I'm finally done removing the gearbox. Next step is to replace the clutch parts. 

I would like to order a new clutch kit but I see on internet 2 diameters : 190 and 200 mm.

The pressure plate which was mounted is Sachs mf190x/mf200. Does this mean I need 190 or 200 mm diameter?

190mm.

May I suggest you add a steel rule to your toolkit, they're astonishingly useful.

Got to be the longest clutch change ever? Lol

We can't all do a 1.4 mpi head gasket change in a lunch break you know

Ha ha, doubt I could now, old bones now.

 

Mind you, this was out and back in on the same day...
