REPLY Many engines do not have lifting rings. Faced with lifting a 1000 lb diesel engine by hand and not having any lifting rings I improvised. Car seat belts must have a breaking strength of 5000 lbs. Naturally this also applies to the fasteners and loops used to reverse the belt direction on shoulder belts. These loops are made from 1/2" diameter steel bar stock and chrome plated. I scrounged half a dozen of these and bolted two onto my engine block. The trick is to place them so as to balance the load approximately level when lift is applied. Twin bank engines are worst so you may have to place one ring on each side at front and back. The stresses placed on a bridle is far greater than a simple in line tension pull. I went to an automotive supply house and bought two 3 foot length of chain 5/16" diameter links plus a chain hook that fit on the end link. I also purchased two shackles whose pin would fit through the eye of the links. 5/16" chain was selected because it had a working strength of 2 tons giving me a safety margin well above the 1000 pound load of the engine. The chain with two shackles on it was my primary bridle and the extra length with one chain hook became my third leg to balance the engine more or less level as it was hoisted. Some experimentation may be required to get it right. Lacking any power assist I used a hand powered 2 ton COME-A-LONG.
