Hello peeps, it looks like I've fallen in love with a beautifulswedish model who is incompatible with my landrover, so am likely tobe selling it at some point so she can move in. Once she's settled inI will get a non-threatening series 1 80" that's been on the cards fora while.She has six wheels, the rear four of which are driven permanently withthe front pair driven only when engaged off-road. There is no diffbetween the two rear axles, just a solid shaft, with the axle centresbeing about a metre and a half apart. I thought that I'd ask youchaps about opinions on this, and if six-wheeler lorries are set upthe same way.It appears that this setup is fine as the reputation for reliabilityof these machines (Pinzgauer) is rock-solid, so I can only assume thatthe wind-up between these two axles is minimal due to them being soclose together, and there are chances for wind-up to be relieved whilethe twin rears are slipping sideways during tight corners.So any thoughts on this? It'll be at least 6 months before the landygoes up for sale, if I don't have a change of heart in the meantime.

Its the usual way to do 6x6, as the axles are close enough togetherthat there is minimal windup between them. The commercial side tendsto do it by having a pass-through mid axle, which has an extra outputfrom the back of the diff, with a short prop linking to the rear axle.The amount of difference between the two axle speeds is negligible,the main difference when going round corners is experienced betweenthe front axle and the rear pair, especially as the front axle has twowheels both turning at different speeds when going round a corner. Theonly downside can be a tendancy to wear out the tyres on one of therear axles quicker than the other, but this is usually onlyexperienced in vehicles which have 6x4 or selectable 6x6/6x4/6x2.Alex

6-wheelers (offroaders and lorries) and transmission wind-up?

The Pinz is smaller and lighter than the 101. And the 101 is sluggish because the 3.5v8 is considerably detuned in the 101 version. Try it with a later 3.5 SD1 or EFI lump in it.

and the 101 has very low gearing.
