Information:

Coupling angle (C) is measured from the position of stem (B) clockwise to stem (A). In the chart, (D) is the length of the hose assembly and (E) is the degree tolerance.Coupling Reconditioning
The chart below shows the tools needed for disassembly and reconditioning of the different sizes of hose.
Couplings can be removed from a hose and used again on new hose. Never install a coupling on a hose that has had oil in it. Do not use a coupling again if it shows any damage. Before installation of a coupling that has been used before, the inside diameter of the stem must be made the same as it was when new. (This is known as resizing.) Failure to do this can cause separation of the hose under high pressure.
Coupling Disassembly
(1) Use a hacksaw with a carbide blade or the knife and anvil and cut through the hose 3.0" (76.2) behind sleeve (1). Put a thick layer of oil on the inside diameter of the hose. Install arbor (2) in the hose. See the above chart for the selection of tools.(2) Install bottom half (3) of the sleeve collet so counterbore (A) is in the direction shown. Install 5P284 Rear Abutment (4).(3) Put the coupling and hose, with arbor (5), in the press as shown. Sleeve (6) fits in counterbore (A) of sleeve collet (3). Arbor (5) fits against abutment (4). Install top half (7) of the sleeve collet. Tighten the forcing screw to remove sleeve (6). It may be necessary to install the grease ram to remove the Sleeve from the larger sizes of hose.(4) Remove the coupling and hose. Remove the sleeve collets and the rear abutment. Install the bottom half of stem collet (8), with counterbore (B) in the direction shown. Install the bottom half of hose collet (9). If a .38" (9.7) or .50" (12.7) inside diameter hose is being disassembled, use the 5P283 Abutment in place of hose collet (9).(5) Install the stem and hose with the arbor in the press as shown. Install the top half of stem collet (8) and hose collet (9). Tighten the forcing screw until dimension (C) is as shown. This will move stem fingers (10) away from the hose and loosen the hose from the stem. Remove the stem and hose from the press.(6) Install the stem and hose with the arbor in a vise as shown. Install strap wrench (10). Turn strap wrench (10) until the hose and arbor can be removed. Resize is necessary before the stem is used again.Resizing Stems
See the chart on page 8 for the tools needed to resize hose stems.(1) Install bottom half (1) of the stem collet, with counterbore (A) in the direction shown. Install 5P284 Abutment in the press as shown.(2) Install finger expander (2) on stem (3). Install the stem and finger expander in the press. Install top half (4) of the stem collet. Tighten the forcing screw until the end of the finger expander is at the
