Gearbox failure

[Ruan]

youre probably right there Ruan, thats what causes the failures in the ma boxes once you swap all the original bits out, logic says youll experience similar issues with the larger box as you push the envelope there too.

I've never stripped one down properly or taken any real notice of the BE boxes in honesty, reckon there's any mileage in placing a steel ring possibly around where the bellhousing meets and also around where the end cover bolts on?

Might help hold the layshafts in place and stop them flexing apart under high torque, whether you'll get enough meat in there to make a difference I don't know... What you really want I'd guess is a plate underneath where 5th gear sits under the end cap to hold that part of the box together... Also a plate underneath the layshafts on the other side, not sure there's any possibility of anything in the bellhousing unless we can find a place to put a thread into to hold a plate...

Something around here - looks possible if it can be made low enough and out the way enough:



Something around where the input and output shaft goes here too - might be possible?



Wonder if it's worth just machining a steel plate that would sandwich between the end of the 5th gear cover and the casing?
