Chain tensioner cleaning?

Thanks for this. I may have fallen into this trap. I have a five chain and had thought that one tensioner out at a time would be okay. Can one make the tools necesary to lock the engine?

I can't believe these weren't designed with a preload spring intially. If it is not too much trouble could you post the PN for the revised chain tensioners?
