So a little update. We fully assembled the front brakes also assembled both rear arms. In between we’ve being throwing ideas around on getting the 6 speed gearbox to line up.
Front brakes looking tidy.
rear arms also done.
BMW have stopped doing the brake line clips now so we’re trying out a new type of clip.
Now the 6 speed gearbox fits perfectly up against the engine. We’ve had to change the clutch type to a 22spline disc to suit the gearbox shaft, normally on the z3’s it’s a 10 spline. Now we’ve set the correct height for the gearbox we need to gain 30mm. The bracket holes line up but it pushes the gearbox too high.
The green circles were fitting a reduced bush by 10mm and the blue circles fitting a 20-30mm dia spacers on the bracket. If we weren’t in a lockdown we could get this bracket custom made but for now this is the best solution we have. The shaft will go away for shortening along with the linkage.
Also in the background the diff is still being discussed, it’s not clear what size LSD unit is needed so lots of measurements are being taken.
Were still having issues sourcing new drive shafts. We tried a set off eBay but they had small case inner CV joints so didn’t fit. We then got a pair from Euros and the ABS ring was 10mm away from the sensor, so we’ve decided to have a go at restoring a set. BMW do a repair kit so looking forward to seeing what comes with it.
One very floppy drive shaft
Removing the dust cap, in hindsight here I should of removed the outer so I could access the circlip.
Very watery old grease.
This is one shaft. Both joints use the same size bearing and cages so don’t panic getting them mixed.
bearing all measuring the same.
joint close up. Just popped it out.
This coming week I’m hoping to get the gearbox permanently in. Waiting on the bushes and a new clutch kit to arrive.
