We decided to make a crankcase mount addition to the engine stand. this will enable use to rotate the engine into the vertical position to allow us to remove the engine mount ring, supercharger, rear section of crankcase and finally the back row of con rods and pistons with sleeves.

First thing we did was make some plates that mount onto each side of the middle section of the crank case  at cylinders 4 and 12.

After tacking some box section onto the plates we then fitted 40 mm shafts into the box and using a laser to ensure the shafts align through the engine.

Next job was to build up a frame each side to mount a pair of bearings.

We then added a pair of bars to enable us to lock of the engine in the vertical position.

We drilled holes in the box section to allow us to plug weld the shafts.

The moment of truth! take the weight of the engine at the rear and remove the engine mount, then rotate the engine into the vertical position.

We then added a couple of extra steady posts, next job removal of engine mount ring and supercharger.
