This is a simple rig to make and it will save you a lot of grief and stress,
firstly get your self a piece of 3/4 or 1" plywood 2ft by 2ft and get 4
medium castors from your diy store or Machine mart and bolt these to the wood in each corner,and off you go.
Lower engine by removing top rear engine bolt, you might need someone to help you with this or use straps around the frame,it will come down on the filter housing,then put some packing under each side of the engine and at the rear
under the gearbox,then remove the other bolt, now you can move the engine
forward and sideways and any were you want.Mine is a bit different as I managed to get a bread tray trolley from my local supermarket and put some plywood on it
