VALVE, LINES AND MOUNTING GROUP 6K4287 - Caterpillar

Do Not push too far. Couplings could be propelled and cause personal injury.
Use only those collets listed in the charts. Collet sizes given permit the best possible alignment.4. Close the press enough to expand the coupling fingers.5. Release the press and remove the coupling. Sometimes the hose and coupling can be separated by hand. This will work on many of the smaller XT-3 sizes.6. For larger sizes and any of the problem smaller sizes, except 19.0 mm (0.75") XT-5 hose, install the coupling assembly in the press using front grip collets (5) and plate (4).7. Close the press and push the coupling out of the hose.8. Use 1U8760 Chain Wrench (6), or a 1U8760 Chain Wrench, to remove the coupling from the XT-5, 19.0 mm (0.75") hose with a twisting movement as shown.Reconditioning Stems
1. Slide expander (1) over the end of the stem.2. Insert the front collets and the stem assembly in the press. Clamp securely and close the press.3. Push the expander beyond bend (A) in the fingers, but do not push the expander against the base of the stem.4. Using a plastic tipped hammer as shown, move the fingers tight against the expander.5. Start stem expander (2) into the stem. Insert plate (3) and the assembly in the press and tighten the clamp.Push the expander into the stem to the location shown in the specific chart that follows.
Do not permit shoulder (C) or (E) of the expander, or plate (3), to push against the stem. With 50.8 mm (2.00") couplings, do not permit the rear jaw of the press to push against the stem fingers.
The 45° 3S8360 Coupling (G), 19.0 mm (0.75"), or, the 30° 3S8359 Coupling, cannot be reconditioned to the full depth. Look through the end of the coupling at location (H) to make sure the end of 5P5232 Stem Expander (J) does not damage the elbow at location (K).
6. To remove the expander, reposition the stem assembly with the stem fingers ahead of the collets and clamp loosely. Reverse the press.Remove any burrs, nicks or scratches that may be on the stem.Fabricating Battery Cables
(1) 9S6331 Crimping Die Assembly.It will be necessary to have either a 9S6331 Crimping Die Assembly (1), or an 8T3046 Crimping Die Assembly for use in the fabrication of battery cables.1. Use knife (2) and anvil (3) to cut the battery cable to the correct length. Strip the insulation from the area to be crimped.2. To install the terminals, install the anvil and die in the press. Position the cable and terminal as shown, then close the press to crimp the terminal.3. Use the correct opening (A), according to the crimping die assembly being used, to crimp lug-style terminals on the cable.Refer to the charts that follow for the part number of bulk cable according to cable size, and for the part number of the different types of terminals.
Straight type terminal.
Flag type terminal.
Lug type terminal.Service Replacement Parts
