the rapid acceleration and deceleration of the shafts makes the helical cut gears change thrust loadings significantly which is sort of the equivelent of using a jack hammer on your bearings over time. If Ive still got them the piccy's of the dead box from brian hejlms county (lt85) provide a perfect illustration of this. I cut the front off of the fubar input shaft to make a clutch alignment tool but he might still have the bits and be able to take some more pics of exactly what turns to swarf behind the isuzu.

a short term solution to the problem is to up the idle speed of the suzi. of course a pure square cut box would be my long term solution, no thrust loading of the shafts then. (just woefull tooth contact to worry about)
