You definitely need to give that nasty Quaife to me, so that you do not continue to ruin gearboxes.
The 900 gear case flexes too much under power. The gears get misaligned. Then things happen like the pinion starts to lose teeth like an amphetamine addict, or misalign the bearing, destroying it, or both.
You need a less flexy case. It is particularly apparent if you take the pinion bearing housing out of the case and look at what's holding the pinion bearing housing. The thin and narrow webs of aluminum that hold it in place are tiny. I wonder if you could weld something in there for reinforcement. In the meantime, all you can really do is to have a machinist make a steel pinion bearing housing for you that takes early Corvette pinion bearings (like 1950s Corvette, same inner diameter for the shaft, but a larger outer diameter - I'll try to find the part number here). Should be easy to turn on a lathe. Eriksson Industries offered an upgraded pinion housing like this for a time, but they are long gone.
If you're paying the money for a better pinion bearing housing, you might as well also get a TIG welding guy to add some extra webbing to around the pinion bearing housing inside the case.
