This Jacobs Kit includes the jaws and nuts for Series 34 type Jacobs drill chucks. To replace these parts is no easy task! To disassemble the chuck, extend the jaws to half capacity and place the chuck on a arbor press or vise. With the bottom of the sleeve sitting on supports, press down on the top of the chuck and the sleeve should move over the top of the chuck. Now getting it back together is the trick. There are 3 different jaws in each kit with 3 different size steps. Install jaw #1 with the smallest step, then jaw #2 with the largest step, then jaw #3 without a step. Turn chuck jaws to closed position and check to ensure that all 3 jaws are properly aligned. Their heights should all be the same! A good grade of grease should be applied to the jaws and nut threads, then the nut halves should be closed around the jaws. Extend the jaws to half capacity, then press on the sleeve with an arbor press. Sounds simple...it is not! Good luck!
