BMW 188 rear axle, final drive ratio 4.75 - Crown wheel and pinion

Final drive ratio 1:4.75 This BMW 188 4.75 pinion shaft of our own production is approx. 3.20mm longer (208.00 3.20mm=210.20mm) than the original BMW pinion shaft. The ZF-LSD (differential) pinion shaft is so precisely matched in length that the pinion shaft must be moved 1mm. This is stated in the written installation instructions that come with the final drive. In other uses, the 3.0mm shaft length does not require any adjustments or modifications. NOTE! There are two different starting heights for the differential housings and LSDs: 1. If the gear ratio is over 3.07:1 and the height measured from the differential gear side is approx. 54.5mm, this final drive will fit this differential or LSD.2. There is also another differential or lock option, if the rear gear ratio is less than 3.07:1 and the height measured from the differential gear side is approx. 47.5mm, an additional riser ring, i.e. an adapter, must be installed between the differential gear and the differential gear unit or lock, which will move the plate gear to the correct position in relation to the pinion gear shaft. This additional riser ring must be approx. 7.3-7.4mm high and the plate gear bolts must be hard black 12.9 e.g. hex bolts. The bolts should be glued with locking glue for safety. A total of approx. 1,000 units of final drive ratio made by a good quality manufacturer have been sold in Finland and the Nordic countries with different transmission ratiosThe BMW 188 rear is used and can be found in the following car models:(identification can be done by the fact that the cheek bearing flange behind the "tump" of the drive shaft is attached with 6 bolts to the stern tube, while the 168 stern flange is attached with 4 bolts, and 210 with 8 bolts respectively)E24 633csi, 635csiE28 518iE28 525i, 535iE28 528i manualE30 325i manualE30 325ix Manual Rear Wheel DriveE30 M3E34 524td manualE34 525i Automatic, Australian modelE34 525i manualE34 530i, 535iE36 323i CarE36 325i manual and automaticE36 328i CarE36 M3 3.0E36 M3 Evo 3.2 rear gear crown wheel no. 2227453E36 M3 USAxE36 DOES NOT USE rear gear crown for wheel no. 1428373Z1 all modelsZ3 M CoupeZ3 M Roadster
