100 Ton Ram Instruction Manual Any coupling assembly (welding of stem, stub end, flange, etc.) must be done prior to starting this procedure. Failure to do so (i.e. welding flange to stem after the swage) can result in serious structural damage to the hose and premature assembly failure. 1a Install the 4" main pusher (M011-065) by sliding it onto the rod cap of the ram cylinder. Make sure that the pusher is all the way on the rod cap. For 1-1/4" - 3" couplings proceed to Step 1b.

100 Ton Ram Instruction Manual 3 Assuring that the hose end is cut square, chamfer the I.D. of the hose 1/8" at a 45° angle. This will aid in stem insertion. If the hose is to be static grounded, follow hose manufacturers procedure for proper static grounding. 4 Lubricate the I.D. of the hose and the O.D. of the stem with Dixon Coupling Lubricant or equivalent. Insert the stem into the hose until the hose end contacts the stem collar. Position the sight hole on the ferrule so that this can be observed.

100 Ton Ram Instruction Manual 6a Install the required die holders ensuring that the seams between the die holder halves do not line up. The die holders are designed to fit one inside the other. A guideline for selecting die holders is: M012-001 1-1/4" - 3" I.D. hose M012-002 4" - 6" I.D. hose Caution! Never use a swaging die as a die holder! 6b Secure the die holders with tie down bars to prevent the die holders from slipping out of the die bed unexpectedly.

100 Ton Ram Instruction Manual 8b Extend all of the jackscrews so that they are contacting the flange. With a wrench, tighten one jackscrew one half turn. Moving to the jackscrew opposite of the one just tightened, tighten it one half turn. Moving to the jackscrew immediately to the right of the first one tightened, tighten it one half turn. Moving to the jackscrew opposite of the one just tightened, tighten it one half turn. Keep repeating this process until all jackscrews are evenly tensioned.

100 Ton Ram Instruction Manual 10b Align the flange face with the pusher. For 4" assemblies, the raised face on the flange will fit into the recess of the 4" Main Pusher (M011-065). For 1-1/4" - 3" assemblies ensure the flange face and the pusher are flush. 11a Loosen the bolt on the tie down bar holding the die in place. Move the tie down bar so that it clears the collar. When this is done, snug the bolt on that tie down bar.

100 Ton Ram Instruction Manual 13a Position a rubber sheet or pad under the die bed. Slowly slide the hose towards the pusher. When the die clears the die holder, one or both halves may fall to the floor. If one half remains on the ferrule, tap it with a mallet until it releases. If both halves remain on the ferrule, it may require the halves be pried apart at the seam. 13b Loosen the bolt(s) on the tie down bar(s) and move the tie down bar(s) so that they clear one die bed spacer.
