Just been checking out an 02K gearbox and thought I would post some info. This is the odd box that looks a bit like an 020 but has a hydraulic clutch and slightly different linkage arrangement on the top. It is fitted to various vag models. I was aware of an 020 style box being fitted to the small block range of engines and have also come across this box in a mk4 golf 1.6 and my mum's Octavia 1.9 sdi. My local garage changed one out in a 1.6 Octavia. I grabbed it for a look and on close inspection I could see that the bell housing is designed to fit on both small block and large block engines. There are various holes and dowel positions that are used in either application. There will be a lot of different ratios too, if it is in a 1.9sdi and a 1.4 petrol. Whether the internals are interchangeable with an 020 I am not sure, yet. Presumably this will also fit the small block 16v engines of which I know zippo about. EDIT: Pics added later in thread. http://www.clubgti.com/forum/showpost.php?p=2068447&postcount=26
Are you saying that we can replace our 020 boxes with a proper clutch type box? Post some photos, and be quick about it! ps. 6 speed I hope?
No, It still has the upside down, wrong way round, back to front clutch.[:^(] You can get a proper clutch though and 6 speed. 02S is your friend.
No. It is done with cables. Which is no bad thing as it clears out the exhaust tunnel of all the rods and linkage, leaving plenty room for a decent exhaust.
^^ Are you left handed Daved? Cannot see how you could draw the above with the wire binding the pages together.
No. Wish I was cos. I recon. the sinister lot are, on average, more intelligent than the dexter lot! Just a miser using the empty, reverse side, of pages!
My Dad's got one of these sat in his Mk4 1.6, 16v, naturally. Interesting it is double drilled for the small and large engines. rubjonny raised the point a while back about the opportunities for a wider selection of gears coming from this, though I'd imagine it'll be gears not diffs that prove mainly useful. Possibilty of a low numbered final driver to suit a motorsport rally gearset - to open it up for track use.
I suspect the 02K will have 4.25, 3.94, 3.66 final drive options myself, with the usual 020 gear set from the driver and gti. I would love to be wrong and find a high 1st gear though.
i think this will be more useful for the MK1 lot, easy way to get a 5 speed on a small block without welding. be even better if you can change the end cap over from a std 020 one so can use a std clutch cable. one thing though, does it have a speedo hole?
It does have a speedo hole and the mounting boss for a clutch cable too. The end casing with green plug is different from the 020 though. But it looks like it use the same bolt pattern as the 020. The gear linkage looks slightly different but may still convert using 020 bits. Will try to check clutch mechanism swapping over the weekend.
Hmm, where to start. It has the larger mk2 16v or mk3 8v sized input shaft for clutch friction disc. The end housing containing the clutch release bearing actuating mechanism have two of the bolt holes in a different location from the 020. There are numerous other subtle differences too. Not really worth me hosting the pics I think. If the 02K bellhousing casing is interchangeable with an 020 main case then that would probably be the best thing about the 02K box. As Rubjonny suggested, it would allow the 020 box to be fitted to the small block engines.........and that is really about it! Out of interest 5th gear was 58 / 38 = 0.745 suggesting tall ratio gear set. If anyone wants further info just ask. Right, lets get rid of the gear oil aroma, and get a cuppa tea and a nutella sandwich in me to make up for the past depressing hour of my life.
oh and of slight interest here I think, the pressure plate from certain MK4 models fits a MK2 with 020 gearbox and gives a lighter clutch pedal
You would need a single dowel flywheel to match the pressure plate if trying this. Will the lighter clutch pedal not be a result of less clamping force on the friction disc though. Maybe not ideal for high power applications then.
not sure, could be they worked around the issue some other way? the guy who told me was told the pp is actually stronger. looking at my msn history its a MK4 1.6 pp you need. he suggests you also need to use the MK4 flywheel, but the later MK3 one might work as you say. its 3rd hand knowledge, but food for thought anyway
The mk3 and mk4 flywheels are heavier than the mk2 petrol ones. They have a larger rim of metal on the outside next to the ring gear.
