  1. INTRODUCTION This instruction sheet covers application, inspection and maintenance procedures for Crimping Head PN 1673672-1 shown in Figure 1. The crimping head is used to crimp SOLISTRAND* terminals and splices onto solid or stranded copper wire sizes 8 thru 2 AWG. This crimping head is designed for use with Foot Hydraulic Pump PN 1583659-1, Hand Hydr aulic Pump PN 1583661-1, or Electric Hydraulic Pumps; PN 1804700-1 (115 VAC) and PN 1804700-2 (220 VAC). Read these instructions, and all applicable references, before inserting the nest or indenter and c rimping any terminals or splices. Warning: To avoid personal injury and potential damage to the crimp head, TE Connectivit y (TE) requires the crimp head to operate at 9,800 to 10,200 PSI [676 to 703 bar]. TE recommends using 10,000 PSI [689 bar] TE Hydraulic Pumps as other manufacturers’ pumps may apply insufficient pressure (resulting in an inadequate crimp) or excessive pressure (resulting in failure of the head). Additionally, the TE pum p must be used to maintain CE certification; if using other manufacturers’ pumps, the user is responsible for self-certification. NOTE Dimensions in this instruction sheet are in millimeters [with inches in brackets]. Illustrations and figures are for reference only and are not drawn to scale. Reasons for reissue of this Instruction Sheet are provided in Section 9; REVISION SUMMARY PROPER USE GUIDELINES Cumulative trauma disorders can result from the prolonged use of manually powered hand tools. Hand tools are intended for occasional use and low volume applications. A wide selection of powered application equipment for extended-use, production operations is available. Hydraulic Crimping Head, PN 1673672-1
  1. DESCRIPTION Main components of the crimping head are: a yoke which houses the indenter and retains the terminal assembly for crimping, a latch which allows pivoting of the yoke on the pivot pin (typically required for splice terminations), a cylinder which contains the head’s hydraulic chamber, a piston (ram) which holds and controls the indenter, and a quick connect/disconnect coupler (cylinder half) which mates with the coupl er on hose or handle control to release or supply pressure. DANGER To avoid injury when using hydraulic equipment, observe the following precautions:  DO NOT modify the crimping equipment in any way.  USE ONLY the nest and indenter, terminals, and wire specified for the head.  DO NOT perform repairs other than those specified in instructional material supplied with equipment. 3. CRIMPING HEAD INSTALLATION Each crimping head is shipped with a coating of lubricating oil to prevent rust and corrosion. Wipe the oil off before installing the crimping head on the power unit. Note that the crimping head is shipped without oil inside the cylinder. To install crimping head, proceed as follows: DANGER Verify that the hydraulic pressure to hose or handle control is released and that power supply is disconnected from electric power unit, if applicable. 1. Thoroughly clean coupling area of handle control or hose assembly and crimping head (see Figure 1). 2. Remove protective dust caps from both quick connect/disconnect couplers. 3. Hold hose or handle control in vertical position to prevent oil spillage. Attach hose or han dle control to coupling section on head. THREAD PROPERLY AND TIGHTEN SECURELY. CAUTION Oil flow must be unobstructed between power unit and crimping head. Verify that all couplers are fully mated and tightened. NOTE If crimping head must be removed after being in production, pressure must be released in the hydraulic system before head is removed. If using Electric Hydraulic Power Unit 1804700-1 or 2, disconnect power unit from power supply. 4. NEST SELECTION (FIGURE 2) DANGER To avoid personal injury, release hydraulic pressure to the hose or handle control. Disconnect electric power unit from powe r supply. 1. Depress the latch and open the crimping head as shown in Figure 2. Figure 2 Latch Indenter
  1. To complete the other half of the butt splice, remove and reposition the uncrimped half of the splice in the nest. Insert the wire and then activate the power unit to crimp the splice. The completed termi nal or splice should be as shown in Figure 5. Figure 5
  1. INSPECTION AND MAINTENANCE DANGER Verify hydraulic pressure is released and power supply is disconnected before following inspection and maintenance procedures, unless otherwise specified in the procedure. Each crimping head is assembled and inspected before shipment. TE Connectivity recomm ends that the crimping head be inspected immediately upon its arrival at the facility of use, and at regularly scheduled intervals to ensure the head has not been damaged during handling and use. Frequency of inspecti on depends upon the following: care, amount of use, and handling of the head; type and size of products crimped; degree of operator skill; and environmental conditions. Cleaning Remove accumulations of dirt and grease on the crimping head; especially in areas where dies are insta lled and terminals are crimped. Clean the entire head frequently with a clean, lint-free cloth. Visual Inspection Refer to Figure 6 and proceed as follows: 1. Visually inspect die closure surfaces for chipped, pitted, or flattened areas. 2. With hydraulic pressure released, inspect the assembled head for nicks, scratches, and cracks . Inspect for cracks especially at the corners of the yoke and around the top of the cylinder. 3. Inspect pivot pin holes and latch pin holes for wear. Replace parts, as needed. Figure 6 4. Activate power unit. Raise ram to “UP” position. Inspect flat and round surfaces of ram for galling (fretting or wear by friction), cracks, or oil leakage. Release pressure and make sure that ram retrac ts smoothly. 5. If head shows evidence of galling, cracks, oil leakage, or rough cycling, return the c rimping head to TE for repairs. Refer to Section 8, REPLACEMENT AND REPAIR. NOTE Once per year, or every 7,500 cycles (whichever comes first), the hydraulic head should be returned to TE for magnetic particle inspection. Additionally, inspect and service the head every month or 1,000 cycles. Refer to Instruction Sheet 408- 8909. Detail A See Detail A
  1. Try to insert the NO-GO member. The NO-GO member may enter partially, but must NOT pass completely through the die closure (see Figure 9b).  If the die closure meets the GO/NO-GO gage conditions, the die closure is considered dimensionally correct.  If the die closure does not conform with the GO/NO-GO gage conditions, contact your local TE representative. Crimping Head Check-Out Procedure If the ram fails to return to the “DOWN” position after completion of a crimping cycle, the cause may be in the crimping head. To determine whether the trouble is in the crimping head or not , release pressure in the power unit. If the ram retracts, the trouble is not in the crimping head. If ram does NOT retract, return the head to TE for repair (see Section 8; REPLACEMENT AND REPAIR ). 8. REPLACEMENT AND REPAIR Customer-replaceable parts are listed in Figure 10. A complete inventory should be stocked and controlled to prevent lost time when replacement of parts is necessary. Order parts through your TE representative or call 1-800-526-5142, or send a facsimile of your purchase order to 1-717-986-7605, or write, or return the entire tool for evaluation and repair, with a written description of the problem to: CUSTOMER SERVICE (38-35) TE CONNECTIVITY CORPORATION P.O. BOX 3608 HARRISBURG, PA 17105-3608 Tools may also be returned for evaluation and repair. For tool repair service, contact a TE representative at 1-800-526-5136. 9.
