    Hello!
    I have a Polonez gearbox (5-speed) with a 1.9D (XUD9) engine in my car
    Two bearings have recently broken apart and damaged the clutch shaft by the way, and now, when everything is put together with new seals, I wonder what kind of oil should I pour into the boxes.
    Previously, it was on Hipol, probably Gl-4, I found a note on the forum that it should be "(...) each of the quality class: API GL-5 and viscosity class: 80W / 90 or API GL-5 and 85W / 90"

    From what I think this Hipol Gl-4 is a mineral oil and when it comes to Gl-5, the author also meant a mineral?
    If so, does it make sense to change the oil to some semi-synthetic now or is it better to stay on Hipol Gl-5 mineral?


    PS: Maybe someone knows where I can still get a bearing no. CBK 083 2RS2P66 (two in the middle, I'm not sure) for the same box?
    Today I traveled over a dozen stores and only one can be ordered, but only a Chinese replacement.

    And where are you from, because in my neighborhood I have a shop where you can buy every bearing.

    Maybe here http://www.albeco.com.pl/617-product-CBK+083+P66_FŁT

    The biggest problem is that it will start to make noise after 2,000. Look for a Russian bearing from a nice one, I don't remember the marking, but it fits.

    Added after 5 [minutes]:

    I found something http://jacars.pl/lozysko-skrzyni-75x30x19-p-3604.html ask about Russian ori.

    It looks like this bearing should have the number: CBK 083 2RS P66 (CBK 0832RSP66) or I found the term CBK 083P66. On the piece of paper my friend wrote to me, he must have made a mistake and wrote PP twice, but it looks like two ...
    This is probably some special bearing with increased precision.
    quote from one forum:
    "It turns out that the gearbox should use bearings with increased precision (ball bearings). The CBK-083 bearing in the gearbox, just like the 6306NR, does not run in an oil bath, but has its own lubricant, so it ends after some time. the flaps from the bearing, there was no trace of grease inside, but neither was there any oil.

    So what's it like with these two bearings? I had one written 6306N and I bought 6306-ZNRC3 and it is covered with a plate on one side, should it be here?
    as for the latter, I do not know whether it should be covered or not (2RS is probably double-covered) but should it be here?

    It would also be useful to have some schematic / catalog of the chest is such a thing achievable?

    The gearbox from the Polonez has racks on sliding sleeves, so we pour a good rare oil into it, it can even be engine oil.
    Pouring dense ones, even with additives, causes difficulties in the operation of synchronizers.
    The box and the bridge made of the Polonaise are designed in contact with the engine power. Inserting a stronger engine first damages the diff and then the gearbox.
    Replace the clutch shaft bearing in the crankshaft 6202 2Z immediately.

    So I can easily pour the semi-synthetic / synthetic gear? I have a Mobil 1 semi-synthetic motor but I will probably buy a gearbox something.
    What do you recommend and what parameters?
    Is the fact that earlier this box was on Hipol and now, when poured in a semi-synthetic, will not deteriorate, for example, the volume of work, greater rinsing / more play on individual parts?

    This engine also ran in polonezes (xud9- Citroen) and the boxes were also different for these engines, which I have matched to it, I don't know this car has already been bought with this engine - Nivka :D

    2RS marking is double-sided and CBK is intended for gearbox. The old boxes had bearings without shields and were running, except for the Polish cbk083 which hummed after a few thousand, but the very old boxes had a Russian bearing on the shaft and they did not rustle.
    Very thin oil, hipol works but much shorter.

    I always flooded crates in my old cars with ATF. The chest is easier to move. Perhaps Opel also had such oil.

    This is the oil we have explained - I'll be looking for something semi-synthetic, probably some Mobil.

    However, as for the bearings, I have two to replace:
    1. 6306N I bought: 6306-ZNRC3 (USA) is covered with a plate on one side.
    2. CBK 0832RSP66 - that's the problem ...
    3 *. As my colleague Megawe suggests, it would be good to also replace the clutch shaft bearing in the crankshaft, but I do not know which bearing we are talking about?

    So you say that it is better not to look for this CBK and instead to give it a Russian bearing that was in the old boxes? I guess I found it original, that's what you mean? link
    From what I can see, it has no covers and this is my 1st (only one - unless I download it)
    I will only add that my chest is a "new type" whatever that means ...
    I'm not sure if they work in oil all the time or not, but if they don't have covers or I take them off, they probably will be fine and from time to time something will splash on them?

    There is still the question of this P66 marking, a guy from a wholesaler told me that it means the accuracy scale in which the bearing is made and that now most / all bearings are made on such a scale, I do not know how this Russian bearing is related to this?

    I have not read more nonsense in my life - 99% of gearboxes are constructed this way. The synchronizers in the Polonaise easily withstand thicker oil, due to the way the friction rings themselves are constructed. The gearbox is designed for thick oil, for a simple reason - it mutes its work.

    Both are damaged because they have been overworked by the constructors, who made anything out of a nice "Fiatowska" box. Revised tooth module and clutch shaft bearing, which strangely breaks apart very quickly, causing the gearbox to noisy despite allegedly being "muted".

    If there was P66, it should be a bearing with this designation. This is not an accuracy class, but a reduced vibration level - I suspect that is why it gets loud quickly.

    Modified tooth module of modes - clutch shaft and intermediate shaft, they would have to be replaced in pairs.

    So if this bearing (CBK) breaks down quickly and becomes noisy quickly, does it make sense to put it there? Isn't it better to put it in Russian instead?

    Well, it's better Russian, as long as you find a Russian original (apparently they were made of better steel - from German tanks ? which Hitler left them). In general, it is not known what quality they present now - the best communist stockpile. If not, use CBK and good oil.

    I do not remember exactly, because I did not dismantle the Polonez box from 15 years - but there were two types of these clutch shaft bearings - they differed slightly in some dimensions, but I do not remember either the outer or inner diameter. And the howl will eventually start anyway - civilized people make this knot on a roller bearing, not a ball bearing.

    I have decided to establish CBK.
    Ordered, although it was not easy, but it worked, most of them have only Chinese equivalents, but I managed to find this original bearing FŁT Kraśnik also I think that you will enjoy the ride for a while :D

    Anyway, thanks to everyone for your hints and suggestions !!!

    Gentlemen, such a question today came this CBK bearing and I wonder if it will improve something if I remove its rubber covers? / Better oil access /
    or will it worsen? / together with the oil, the filings will get into the bearing, etc. /

    On the other hand it the second the bearing is only covered on one side so filings can get there anyway, what do you think?

    Little update:
    The gearbox is assembled on the CBK bearing and so far everything is fine, I flooded Mobilube HD-A 85w-90 (mineral) with Mobilube and on the cold gearbox the first and second gears come with resistance, but in some time (probably before winter) I will want to change it to synthetic then we will see what will come of it ... :)

Topic summary

The discussion revolves around the oil change and bearing replacement for a Polonez gearbox (5-speed) paired with a 1.9D (XUD9) engine. The user seeks advice on the appropriate oil type, considering a switch from Hipol GL-4 to a semi-synthetic or mineral oil meeting API GL-5 specifications. Participants suggest that thinner oils may be more suitable for the gearbox to avoid issues with synchronizers. Various sources for the required bearing (CBK 083 2RS2P66) are shared, with recommendations leaning towards Russian bearings for better durability. The user ultimately decides to use the CBK bearing and Mobilube HD-A 85W-90 mineral oil, noting initial resistance in gear shifting but plans to switch to synthetic oil later.
