All the selector forks come with that coating. I was told by Jan that the coating protects the selector fork. I think he referred to it as a "diamond" coating. It does wear off very quickly though (on the 5th/reverse selector) and I don't think it actually gives much protection.

Hi
The selector forks are being covered with brass from the groove that the forks run in.
You would battle to remove it and I would not recommend sand blasting as an option either.
Petrol or even Paraffin will remove the loose flakes. The rest will remain.
The problem will be worse if you use an API GL-4 gear oil.
Regards Vincent

Thanks for all comments.
My intention is to remove the flakes very carefully with one of the flap sanders at work .
The coating is very rough , and I think it might cause damage by "grinding" the grooves and polluting the oil - I don't want that flakings in the oil anyway.

Hi Danie,
A quick thread-hijack ans I will not post here again:
I noticed on the photo of your Fiat engine that you have a weber carb on your Fiat engine. That spells disappointment against steep inclines taken at speed. I suggest you consider multi point fuel injection at some stage (or throttle bodies). Man, that will be one mean Lada motor! I, for one, will definitely make a screen saver of a Fiat motor with throttle bodies in a Lada! A DOHC cross flow motor in a Niva is a passion thing with me - just imagine that Fiat motor happily screaming at 7000 rpm up against a sand dune! Music to be remembered for ever.
Regards,
Fanus

OK Marius, If you are happy with your decision - let it be. I'm tired to argue. Just some facts: > No one Niva after 1998 came with the old system. Before 1998 they are all with the old systems. All Lada Niva 1700 gearboxes are identical.> Why is still not indicated into the catalogue you can ask your suppliers. > The oil have to be changed in the engine and transmission after first 2500-3000 km, I agree - but this is so called routine oil change or service, not repair. To strip half of the transmission to replace a washer after 3000 km sounds beyond belief. The gearbox is already run-out and to release the nut which ensure the all tightness inside, means to start again from the beginning. And who can imagine that a washer outside gears has significant role for the run-in of the all parts inside gearbox for the first 2-3000 km and needs to be throw away afterwards. > No one of the parts importers in RSA since 1996 thought about the thin washer - it is too little and simple to mention (but actually very important) - another reason for the absence from the cars now. This washer is for single use. I've got left 1 or 2 and keep them for my car - it's model 1997. > The parts of both system must not mix. The spring flat washer is ~1.5 mm thick and this thickness is important for the all tightness of the gearbox-intermediate shaft joint. If you have the tin thin washer instead of the thick one, your vibrations there are more than average. > Read very carefully all your manuals and service books. If there is not written in black and white about replacement of the washers, this remains only your idea. > Definitely point your fingers at the professionals in the garages. They are not specialists, they are people with tools. Not all of them but majority. It's a horror there and you are happy not to know what they do to your cars. Two years I used to work as group service manager in Pinetown and I know what I'm talking about. > No one product of AvtoVAZ is called back to correct inherent problems till today. That not makes the car the best in the world, just a clear fact only. Ventz Ventz, i do not agree with the red colored text above. I will post pictures of output shafts later this week. As for the back nut systems: in belgium they came with the 1.5 mm spring washer since the multipoint version (2001). Before that they came with the spring and the lock washer.

Ventz has been inactive on this forum for quite some time now - so I guess he would not respond? This argument was basically repeated elsewhere at a later stage - so very little point in coughing it up now.

marius, i was not talking about the nut history, but about the inner part of the output shaft itself and the components on it

Ok but the point is that Ventz would probably not respond.

That's normally not so bad Ari - you probably just need to replace the Pressure Metal Ring (2101-1701038) between the box and the clutch housing.

If you need one, just give me a buzz . I've just ordered two from Pavel - should be in the air by the end of this week. Those rings are "must have" items, and all owners should have a spare one in the toolbox. Don't worry - I have no intention of making any profit. Danie P.S. The 2nd ring is not for sale - please order one yourself.

I am ok but thanks as I have a 31 kg parcel building in Pavel's shop which should be coming soon and it will have the thrust rings in.

hi guys,
what would cause a noise cumming from the gearbox when idling but when clutch is pressed the noise goes away!?
could it be one of my bearings? i have read the post before but no mention of this! also a member suggested ladaworld for bearings...! how do we get in touch with them.
as i have just put the gearbox back in with new clutch kit, and still the noise is there...please can i have some guidance!

THRUST BEARING MOST OF THE TIME It can't be the Thrust Bearing Mike - according to Shaine the noise goes away when the clutch gets pressed. If the Thrust Bearing is indeed faulty, it would get noisy when the clutch get pressed - for a very simple reason: A Thrust Bearing starts rotating, and becomes under stress , when the clutch get pressed. One (or more) worn bearing(s) at the Gearbox is most probably causing the noise. Danie

if you have no gear shifting problems, a set of new bearings, a new thrust ring and a set of gaskets will do

Thanks, the problem started when I replaced the clutch after the thrust ring effectively melted on me while on the freeway.

what would cause a noise cumming from the gearbox when idling but when clutch is pressed the noise goes away!? That is quite normal for a Lada UNLESS the noise is excessive. If it is very noisy it is most probably the clutch release bearing. Marius

Go and compare the noise to that of another car from the 70's and you will find the Niva box is actually quiet.
