(1) The 2P5535 Stud Remover Group is made up of .750" (19.0) extractor (1), .875" (22.2) extractor (2), 1.00" (25.4) extractor (3), body (4), bolt (5), and washer (6). The 5P250 Stud Remover Group is made up of 1.12" (28.5) extractor (7), 1.25" (31.8) extractor (8), 1.38" (35.1) extractor (9), 1.50" (38.1) extractor (10), bolt (11), washer (12), and body (13). The extractors do not use threads to pull, so they will not do damage to the stud threads. Both groups can be used with studs having either coarse, fine, nonstandard or metric threads.(2) Find the size of the stud to be removed and use the correct extractor.(3) Put together body (4), washer (6), bolt (5), and the desired extractor (1), (2), or (3). Use anti-seizure compound between body (4) and washer (6), and between washer (6) and the head of bolt (5). Bolt (5) has left-hand threads.(4) Put the assembly on the stud. Hold the body with one hand and turn bolt (5) counterclockwise with an impact wrench. Do this until body (4) and the extractor begin to turn with bolt (5). This makes the extractor tight on the stud.(5) When the complete assembly begins to turn, remove hand. Turn the assembly counterclockwise until the stud is removed.(6) To remove the stud from the tool, hold body (4) with one hand and turn bolt (5) clockwise with the impact wrench until it comes approximately .50" (13,0) out of body (4). Give bolt (5) sharp knocks with a hammer; the stud will fall out.(7) Tools (I) and (II) can be made for installing studs. The stud must be held with vise grips when removing tool (I). Standard coupling nuts (E) are normally only available in coarse threads. (A) - weld, (B) - standard hex stock, (C) - standard full nut, (D) - standard bolt, (E) - standard coupling nut.
