My favourite tool

‘This is a special tool Bill made many years ago for removing the crankshaft sprocket from a Maserati V8,’ says Andy Heywood. ‘Normal pullers bend the sprocket or break teeth off, but this won’t. You heat the sprocket cherry red with oxy-acetylene, wind this puller onto the thread on the nose of the crank, screw down the middle piece and off it comes. Bill’s engraved, “Maserati Crank Puller, W Mcgrath” on it in his lovely copperplate handwriting.’
