I didn't have an engine puller so a friend helped me lift the engine out of my Spitfire to replace the clutch. When I put the engine back in another guy helped me and we almost dropped the engine and both got major back pain. I realized that friend 1 must have done 75% of the lifting. Next time: engine puller.
