Turbo7379 3 Posted May 30, 2007 I'll be fitting my KAAZ diff this week & I'm wondering what's the procedure for fitting & seating the bearings . I've new bearings ordered but I've read that they need to be fitted in exactly the right place on the diff . My thinking is not to press them on fully , assemble the diff & cover loosely on the box & tighten the speedo drive in to seat the bearing in the correct place . The other question regards what oil to use . The diff comes with 2L of KAAZ oil which I can use but you are supposed to change the oil after bedding in the diff . My favoured oils are normally Castrol Syntrax or Mobil 1 gear oil but you are advised by KAAZ not to use synthetic oil . Maybe I should buy some ordinary 75w-80 oil , use that to bed in the diff & then change to the KAAZ oil ? Share this post Link to post Share on other sites
boombang 2 Posted May 30, 2007 Deffo only use pure mineral oil as they say Also follow the bedding in instructions carefully. No idea bout the bearings though, but sure someone will know. Share this post Link to post Share on other sites
jonah 1 Posted May 31, 2007 On the standard diff and the Quaife ATB the bearings need to be pressed fully home until the inner track meets the shoulder on the diff casing. I would be very surprised if this is not the case on the Kaaz as well. There is a large axial load on the diff in use (because the final drive gears are helical), so if the bearings weren't positively located, they wouldn't stay in the same place for long!

Turbo7379 3 Posted June 1, 2007 Started fitting diff today . Everything was going well until I started to reassemble the diff housing when I discovered that the extension housing wouldn't go on fully . After some measuring & a lot of head scratching I discovered that the new bearings I fitted were 1mm thicker than the old ones . I purchased these in my local motor factor & they are the correct number ( 69349/10 ) but they are unbranded so I suspect they are cheapo russian made bearings . I'll try to source some decent brand bearings in the morning otherwise I'll refit the old ones . I'm mad as hell as I wanted to get this finished tonight .

VisaGTi16v 1 Posted June 1, 2007 (edited) Looks like you have as bad insomnia as me! Anyway. I am fitting a quaife at the weekend and I just bought a pair of new bearings from Peugeot. The are stamped, made in Poland. I will measure them with a accurate vernier at work later thats if I dont go mad and make my head explode due to not being able to sleep! They were about £28 each +vat Should be able to get your money back as they are wrong Dont you have to mill/grind out part of the diff housing when fitting a kaaz or a tranx diff as well?

VisaGTi16v 1 Posted June 1, 2007 Here you are. Give or take the odd hundreth of a mm, the large outer ring is 13.46mm thick and the widest point if you include the inner bearing which sticks out more is 17.44mm Share this post Link to post Share on other sites
Miles 331 1 Cars Posted June 1, 2007 I just buy them in Bulk at my bearing supplier, Most of the ones I get are made in Japan but I do see allot of Pug stuff now made in Poland as they have a factory there now. Share this post Link to post Share on other sites
Turbo7379 3 Posted June 2, 2007 I've just had another bad day . Ist thing this morning I rang around all the local bearing stockists to source another set of bearings . I got lucky at one place who had ordered a pair in for somebody 2 weeks ago but they were never collected . They were the same make as the ones I had (Neu) so I got them to measure them . They were 17.5 mm approx whereas mine were 18.2 mm ! I told them I'd be down shortly to collect them but unfortunately I got held up & it was 2 hours before I arrived at the motor factors . I found the guy I was talking to earlier & he started looking for the bearings which he'd left sitting on the counter for me . No sign of them so he asked one of the other staff members where they were . Turned out that the guy who had originally ordered the bearings had arrived an hour before me & collected them . I tried another few places when I was on the road but nobody stocked the bearings . One place rang timekin direct & they were able to work out exactly what bearing I needed from the old bearing I had brought with me . They could supply them for £15+vat , 2 day delivery time . No good for me as I'm racing on Sunday but I think I'll order a set & fit them next time the box is out . My driving around wasn't a total wasted journey as I managed to find Comma EP 75w-80 mineral oil , GL5 spec & it even says it's for peugeot boxes on the back . Even better that it was only £13 for 5 litres ! Anyway I fitted the KAAZ diff tonight using the bearings off the old diff . They were still in good condition after 138k miles but new ones would've been better . Instead of taking off the gearbox I dropped the front subframe which is a lot less hassle IMHO . The diff swop went without hassle apart from the bearings & I didn't have to modify anything to fit the KAAZ . The supplied instructions don't seem to cover the pug diff so I has to guesstimate the torque wrench setting for the crown wheel bolts . To refit the cross member I used a big trolley jack to lift it into place slowly while guiding on the steering joint . It's a good idea to loctite the 6 bolts that hold the crossmember on as they can work loose . Without the bearing hassle I reckon it took me 3 hours to fit the diff this way . Taking off the gearbox would take a lot longer . Share this post Link to post Share on other sites
VisaGTi16v 1 Posted June 2, 2007 (edited) Fitted my quaife today. Well when I say I did, I mean my friend did with some assistance from me heh. We did it by unbolting the exhaust, lowering the alternator, removing the lower engine mount and there was easily enough room to tilt the engine forward without having to touch the subframe or remove the box. Not sure if the lower front cross member is different on the Visa to the 205 but there cant be that much more room. I had to move the radiator miles forward and slant the top to fit the full length mi16 manifold in for example with a mega thin fan in front. He had to mill of a tiny bit of this rib inside the gearbox side of the diff housing as it fowled the inner bolt side of the quaife for some reason. Only had limited testing time due to idiots in my way on the road constantly pulling out as I tried to do a few laps of roundabouts heh, will have to wait till the sprint next weekend!
