  • Page 6 Handle Assembly (cont’d) The wires, RED and GREEN go through the handle and manifold for the micro switch. Then the BLACK and WHITE wires go out through the trigger housing until the trigger is connected. At this point you can push the trigger into the trigger housing hole in the handle.
  • Page 7 Handle Assembly (cont’d) With the handle attached to the manifold put a small amount of lubriplate grease around the holes in the top of the manifold where the barrel connectors go. Then put some lubriplate grease on the assembled barrel connectors ( o-rings and back- up rings) and push carefully into the holes in the manifold.
  • Page 8 Handle Assembly (cont’d) When sliding the hydraulic cylinder onto the barrel connectors, be careful when not to pinch or tear the o-rings or back up rings. Attach the hydraulic cylinder to the handle using a # 10-32x3/8” BHCS. Put the limit switch rod into the tool before the puller gets screwed into the end cap.

  • Page 15 Section #3 Limit Switch Housing Assembly...
  • Page 16 Limit Switch Housing Assembly, (cont’d) Mount the micro switch to the limit switch mounting plate using two #2-56 x 5/16 SHCS View after assembly Place a .125 x .75 dowel pin and the actuator into place, making sure the dowel pin is centered in the housing.
  • Page 17 Limit Switch Housing Assembly (cont’d) Use a #8-32 x ¼ BHCS on each side of the housing to lock the dowel pin into place. LC-022BC-02M Lee Spring #6 – 32 x ½ SHCS Now with the spring and SHCS in place attach it to the housing.
  • Page 18 Limit Switch Housing Assembly (cont’d) View of switch plate attached to the housing. #8 nut Now place the #8-32 X 7/8 lock down SHCS into the bottom of the housing and into the #8 -32 nut and slightly tighten. #8 SHCS...
  • Page 19 Limit Switch Housing Assembly (cont’d) Now run the red and green wires through the housing, as shown, Using two #10 – 32 x .375 SHCS tighten the housing to the handle assembly.
  • Page 20 Limit Switch Housing Assembly (cont’d) Cable tie the wires Solder the wires as shown in photo. Red to common. Green to Normally closed. Put rear cover on the tool.
  • Page 21 Section #4 BTT20SF Cutter Nose Assembly...
  • Page 22 BTT20SF Cutter Nose Assembly (cont’d) With the handle assembly complete place the limit switch rod into the hydraulic cylinder. Limit switch assembly Bronze sleeve Washer Retaining ring Set screw is loctited into place at .420” outside of the limit switch rod.
  • Page 23 BTT20SF Cutter Nose Assembly (cont’d) The jam nut (left hand thread) is placed onto the puller and screwed completely down onto the puller, almost coming off the other end of the puller. Place the puller into the end cap inside the cylinder and screw the puller until it bottoms out.
  • Page 24 BTT20SF Cutter Nose Assembly (cont’d) Close the puller using a pair of special vise grips and slide the spring onto the puller. Then remove the vise grips. The sleeve goes on next, but you have to start a dowel pin (3/.16”X 5/16”Long) into the sleeve.
  • Page 25 BTT20SF Cutter Nose Assembly (cont’d) Now compress the puller again using the vise grips and slide the sleeve onto the puller. This is how the sleeve should look once on the puller. Now using a arbor press, push the dowel pin into the sleeve...
  • Page 26 BTT20SF Cutter Nose Assembly (cont’d) This is about how much of the dowel pin should remain out side of the sleeve for now. Now using the Arbor press once again push the sleeve down until it pops into place Once in place this is what it should look like, almost flush with the puller.
  • Page 27 BTT20SF Cutter Nose Assembly (cont’d) Now finish installing the dowel pin using the Arbor press until it is flush with the sleeve. If not completely flush tap in with a hammer and punch. Slide cutter anvil over sleeve to make sure there is no interference with dowel pin.
  • Page 28 BTT20SF Cutter Nose Assembly (cont’d) Lock the collar cutter extension into place with 3 #8-32x1/8” socket set screws. There will be 4 #10-32x3/16” socket set screws holding the Cutter anvil into the extension. Place the cutter anvil into the extension and apply a small...

  • Page 30 Installation Nose Assembly (cont’d)
  • Page 31 Installation Nose Assembly (cont’d) Place the limit switch rod into the end cap of the tool. Screw the jam almost all the way through the puller and then screw the puller into the end cap of the tool (left handed threads).
  • Page 32 Installation Nose Assembly (cont’d) Using a pair of special vise grips (10LW from MSC) close the puller enough to put the socket for the jam nut over the puller. Once the socket is on the puller remove the vise grips and push the socket into the slots on the jam nut.
  • Page 33 Installation Nose Assembly (cont’d) Apply a torque wrench to the socket and torque to 150 ft. lbs. (counter clock wise). Then remove the socket and torque wrench from the puller. Now apply the pair of vise grips to the puller once again to place the anvil over top of the puller.
  • Page 34 Installation Nose Assembly (cont’d) Using a spanner wrench screw the anvil down until it bottoms out on the piston of the tool (clock wise). Once the anvil is in place you need to put the 3 set screws into the piston to lock the anvil into place.
  • Page 35 Section #6 Setting the limit switch First check to see what your limit switch is set at, the specification for the limit switch for the cutter tool and installation tool is .390”-.400”. If the switch needs to be adjusted loosen the lock down screw. The longer limit switch rod is for the cutter tool which is 6.8”...
  • Page 36 Setting the Limit Switch (cont’d) Adjustment screw, adjust the screw as needed to achieve the correct switch setting. When adjusting the limit switch, the LED light on the test box comes on when the circuit is made by inserting a fastener or other object (depth micrometers) into the puller of the tool...
  • Page 37 Setting the Limit Switch (cont’d) The limit switch test box, you can check the trigger switch and the limit switch to make sure they are adjusted and working properly. Showing the test box connected to the tool by means of the lemo connectors.
  • Page 38 Setting the limit switch (cont’d) Once the switch has been adjusted within the specification of .390” - .400” snug the lock down screw down. Then check your reading once again to ensure the setting is still within the specification. If so, tighten down the lock screw for the final time.
