316 viewsMy original pulley lock that I got a previous mechanic to whittle out of steel for me. It's rough but it still serves me well to this day. This is what inspired me to design the newer version, using www.emachineshop.com CAD software and manufacturing.
Though it can be used with the engine out of the car, it makes the job much easier when the engine is in the car and the pulley fan needs to be removed.

221 viewsTop view of the mounted pulley lock with the pulley lock mounting bolts threaded all of the way into the fan housing retaining mounts. The mounting bolts are snug-to-almost-loose -- there's no need to tighten them but it is a good idea to thread them in as far as they will go yet still leave the pulley lock parallel to the fan housing.

227 viewsThe pulley lock can not be pushed into the teeth of the pulley fan! Because of the teeth and curvature, it just won't happen and forcing it will damage the items.
