408- 8914 hydraulic crimping head 1752787- 1 3 of 4 rev b tyco electronics corporation each crimping head is assembled and inspected before shipment. tyco electronics recommends that the crimping head be inspected immediately upon its arrival at your facility, and at regularly scheduled intervals, to ensure that the crimping head has not been damaged during handling. frequency of inspection 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. 6.1. cleaning remove accumulations of dirt and grease on the crimping head, especially in areas where dies are installed and terminals are crimped. clean the entire head frequently with a clean, lint--free cloth. 6.2. visual inspection refer to figure 3 and proceed as follows: 1. 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. 2. inspect pivot pin holes and latch pin holes for wear. replace parts, as needed. figure 3 check these areas for cracks check die areas for damage check for excessive wear at pivot pin and latch pin 3. activate power unit. raise ram to up position. inspect flat and round surfaces of ram for galling (fretting or wear by fric tion), cracks, or oil leakage. release pressure and make sure that ram retracts smoothly. 4. if head shows evidence o f galling, cr acks, oil leakage, or rough cycling, return the crimping head to tyco electronics for repairs. (refer to section 7, replacement and repair). once a year, or every 7,500 cycles (whichever comes first), the hydraulic head should be returned to tyco electronics for magnetic particle inspection. additionally, inspect and service the head (as described in figure 3) every month or 1,000 cycles. refer to instruction sheet 408--8909. 6.3. 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 or not the trouble is in the crimping head, proceed as follows: a. electric hydraulic pump 1583660- [ ] press the retract/release button on the hand remote pendant or foot remote, and hold for several seconds. this will release any pressu re in the hydraulic system. if the ram returns to down position, the trouble is not in the crimping head. if ram does not return, ensure that the coupler is fully engaged. if coupler is engaged and ran still does not go down, return the crimping head to tyco electronics for repairs. b. foot hydraulic pump 1583659- 1 depress the pressure release pedal. c. hand hydraulic pump 1583661- 1 activate the pressure release knob. 7. replacement and repair customer--replaceable parts are listed in figure 4. a complete inventory can be stocked and controlled to prevent lost time when replacement of parts is necessary. order replacement parts through your tyco electronics representative, or call 1--800--526--5142, or send a facsimile of your purchase order to 1--717--986--7605, or write to: customer service (38--35) tyco electronics corporation po box 3608 harrisburg pa 17105--3608 tools may also be returned to tyco electronics for evaluation and repair. for tool repair service, contact a tyco electronics representative at 1--800--526--5136. note i
