When making adjustments to the prop, it is essential to tension the centre bearing; this means applying pressure to it before it is bolted in place, otherwise it will simply fall apart.
If the centre bearing is on the front section of the prop (as in 325i, 318i and), then push the bearing about 3mm towards the gearbox and then tighten the bolts up. If the bearing is on the rear section (as in E30 M3), the bearing is tensioned toward the diff.
E36 Prop bearing
Moderator: martauto
I'm using an e36 328 prop on my m52 swap by installing the e30 center bearing mounted backwards. The e36 prop has the bearing on the rear half of the prop, should I tension it towards the diff as you would normally, or, since I have installed it backwards, tension it the other way, towards the gearbox?
