408 - 8704 rev b 8 of 10 6.1. daily maintenance it is recommended that each operator of the dies be made aware of-and responsible for-the following steps o f daily maintenance: 1. remove dust, dirt, and other contaminants with a clean brush, or a soft, lint -- free cloth. do not use objects that could damage the dies. 2. make certain the dies are protected with a thin coat of any good sae 20 motor oil. do not oil excessively. 3. when the dies are not in use, mate them and store in a clean, dry area. 6.2. visual inspection 1. remove all lubrication and accumulated film by immersing the dies in a suitable com mercial degreaser that will not affect paint or plastic material. 2. make sure all die components are in place. if replacements are necessary, refer to the replacement parts listed in figure 11. 3. check components for wear. remove and replace worn components. 4. inspect the crimp area for flattened, chipped, cracked, worn, or broken areas. if damage is evident, the dies must be repaired before returning them to service (see section 7, replacement and repair). 6.3. gaging the crimping chamber the die closure inspection is accomplished using plug gages. a suggested gage design an d the go and no- go diameters of the plug gage elements are shown in figure 9. figure 9
408 - 8704 rev b 9 of 10 the following procedure is recommended for inspecting the die closures: 1. mate the dies until it is evident that they have bottomed. hold the dies in this position. 2. align the go element with the crimping chamber. push element straight into the crimping c hamber without using force. the go element must pass completely through the crimping chamber as s hown in figure 10 . 3. align the no-go element and try to insert it straight into the crimping chamber. the no-g o element may start entry but must not pass completely through as shown in figure 10 . if the crimping chamber conforms to the gage inspection, the crimping die is consider ed dimensionally correct and should be lubricated with a thin coat of sae 20 motor oil. if the crimping chamber does not conform to the gage inspection not, the dies must be repaired be fore returning them to service (see section 7, replacement and repair). for additional information concerning the use of a plug gage, refer to instruction sheet 408 -7424 . figure 10 7. replacement and repa ir the parts listed in figure 11 are customer-replaceable. a complete inventory can be stocked an d controlled to prevent lost time when replacement of parts is necessary. order replacement parts through your te connectivity 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 (038- 035) te connectivity corporation p.o. box 3608 harrisburg, pa 17105 3608 note dies may be returned for evaluation and repair. for die repair service, contact a te representative at 1- 800 -526-5136.
