As gerard says, it is not made clear enough yet to give you a direct answer... but another thing to check is to make sure the PTO is not engaged... and I would like to explain what the point of all this is... (since it is not explained very well in anything I have read) If you already know this, then ignore.. The whole point is to adjust end play of axles so that they just firmly touch each other at the center of the differential thereby applying some axial preload to the wheel bearling. If the bearings are too loose, they do not seat properly in the cups and there will be side (axial) motion (sounds like "clunks" when turning, or with side to side forces like when dropping into a furrow) and if they are too tight, there is excessive axial load on the bearings and you might gall the ends of the axles which have relative motion when turning or spinning one wheel. This method provided by Ferguson, is a little bit ambiguous since it is not directly measuring the end play (or axial preload), but relating the preload to the observed amount of friction in the bearings of the transmission relative to the friction between the ends of the axles. When you try to turn one axle, and you see that the other one rotates in the opposite direction, nothing is rotating in the transmission. If you are rotating one axle that is pushing against the other axle just firm enough to create end friction sufficient to rotate it in the SAME direction as you are turning it, the transmission IS rotating and HF says that this is the ideal setting... Now you can see why neutral and no PTO are important. If not in neutral, you will never get there because you couldn't shove the axles together tight enough to make the axle end friction great enough to turn over the transmission AND ENGINE without breaking something (probably the axle housing). Likewise, if the PTO is engaged, you are trying to turn the PTO and hydraulic pump WITH the transmission and you will be again be making the axles too tight together... I am sure this doesn't answer your question, but maybe it helps... JIm
