ATRACTOR dismantling st an d, recently introduced by V. L. Churchill and Co., Ltd., Walnut Tree Walk, London, S.E.11, for use in the repair of Fordson and Ferguson tractors, is an item of equipment which should prove of considerable value to all those whose activities include the frequent overhaul of machines of this type. An important feature is the fact that these stands can be used in the field as well as in the workshop, so as to obviate the need for transporting a tractor back to the depot for repair.
From the accompanying illustration it will be seen how, by the use of the dismantling stand, the tractor is split up into engine, gearbox and rear transmission assemblies so that each is loca1ed for efficient working. When the stand is being brought into action the rails are placed on the ground underneath the tractor, a length extending in front to allow the engine and gearbox to be moved forward.
One small trolley is then placed on the rails and bolted to the engine sump, and another placed in position beneath the gearbox. The bolting face of the gearbox and all controls and other linkages, are then disconnected so that the power unit can be pushed forward on ti,e front wheels and the appropriate rail trolley.
A stand is then bolted to the rear end of the engine, and the trolley is pushed forward so as to give additional support to the front of the engine. Front-axle assembly, radiator and cylinder front-cover can now be removed and an engine-stand bolted into place.
The connections between the gearbox and rear transmission are then unbolted, a transmission support placed in position, and the gearbox unit rolled for= ward. Then a jack is run up under the vansmission housing, after which the rear wheels can be removed.
