Currently putting the car all back together after re under sealing and I have come across an interesting problem for want of a better description.
I am running a CR getrag mounted to standard M30 on standard engine mounts,
the gearbox cross member I fabricated myself and the gearbox is mounted as high as possible in the car, with barely a finger spacing between it and the tunnel.
So... I'm bolting the drive shaft back on and realize the rubber donut is cracked, I by a new one locally (after sizing up with what I had turns out to be a E36 joint??? who knows why, but it fits nice), but the problem I am getting to is the centre drive shaft bearing and the whole alignment of the driveshaft and the output of the gearbox.
With the gearbox and engine mounted as described above (I believe this is as high as possible to go) and when I bolt up the drive shaft, the centre bearing is approx 30-33mm
lower than the mounting tags on the floor of the car, I have to really push the drive shaft up hard to get it into place to be able to bolt the centre bearing up, this is then putting a lot of load on the centre bearing, the output bearing of the drive shaft and the flex joint.
My conclusion is that either I have the wrong centre bearing (is this possible?) or that the CR box is perhaps taller than the standard box and that the out put is in a different place, or that because my car was originally an Auto trans the mounts are different??
Anyway, I have found a nice solution to the problem, I am simply going to space down the centre bearing by 30mm with some nice alloy spacer blocks my tool maker friend is making for me, will still have loads of ground clearance, the drive shaft is still well up in the tunnel
Anyone else come across this??
