    This will have to go off to a specialist to be rebuilt.
    Have been collecting various parts for this over the past year as they come up on eBay and the like.

    This is most of whats needed, including syncro, and all the bearings, seals, o-rings, various snap rings and bolts etc.

    Meet one of BMW's most overpriced parts, the 230 bearing and sleeve.

    The case bolts have been removed and blackened ,along with the the shifter linkage and fill and drain plugs.

    That's pretty much how things are at the moment. The exhaust is away being welded , but other than that most of what I wanted to get done before moving onto the body is done.
    The engine might get stripped down and various bit vapour blasted and plated, but think the major engine work will wait until there is a painted rolling shell for it to be fitted to.

      Hi

      Did You purchase ballbearings from BMW ? If they are not original bearings, You should check they have same size balls as original bearings.

        HI Harri, thanks for your comment. Only the expensive bearing shown alone is a BMW part. I was lead to believe three are just generic bearings and then two more unique bearings.

        So the front layshaft bearing is a FAG 6305/C3 and the rear a FAG 6306/C3
        The output shaft a FAG 6306/C3.
        The input shaft bearing I got from a parts site and it was at least advertised under the BMW part. This is it. http://www.oldbenz.co/koyo-bearing-6306nr-72x30x19

        Can I ask which bearings caught your eye and you think may be different than stock ?
        Thanks

            Great work and I like how you repainted the shocks to look factory.

              Hi

              My 265/5 got rebuild by professional year 2010. When I collected parts he advised me to buy only original ballbearings from BMW, generic bearings may have smaller balls and can't handle axial loads.
              Since this happened 2010, I can't remember generic bearing brands, bearing numbers and which one/ones makes problem. I remember he also told layshaft front bearing is fragile due it is "undersized".

                Thanks Harri, I will speak to the gearbox builder about this and see what he says. I had a layshaft bearing replaced not long after I got the car, so not sure whats in there now would be original BMW, or a generic part fitted.

                I looked at what BMW supplies, as ECS Tuning rather helpfully has pictures of nearly everything. This is the front layshaft bearing which is also a FAG 6305/C3. The other numbers differ to mine and not sure what they relate to. My aftermarket part is marked ' FAG 6305/C3 H170-1747.HB ' .

                  Their catalog is really helpful that way. Some people have been negative on ECS recently, I continue to use them for just this reason.

                  Similarly, this thread is a great ptoto reference. Thanks for taking the time to document all of this.

                    I wish there were an ECS equivalent in the UK, but there really isn't anyone close. I find there website extremely useful and did order a new lower evo airbox from them, along with a couple of other bits that spread the cost of shipping.

                        how did you organize the sandblasting? did you send per group? (for example today the cgear and the following week the differential?)
                        did you send it all here? https://www.tsrvapourblasting.co.uk/services

                        p.s, the stickers of the crick, the control unit and the fuse box I had them made again for the first time by pukar .... you owe me the patent

                          Most of the blasting and powder coating , was all done in one batch, so all the suspension arm, struts, the long range fuel tank, anti roll bars etc. The diff was done in another batch with a couple of small parts like the fuel pump bracket.
                          Some of the vapour blasted aluminium parts ( the upper sump , alternator, diff cover etc ) were done in one batch . TSR vapour blasting is 15 minutes from home and there is also a local powder coating company 20 mins away, so isn't really a problem if I need just one or two parts done.

                          Pukar does some great decals to finish off the refurbished parts. I haven't got any for the fuse box yet,as that's a future project, but seems like you've done the hard work already on these,
