Piper PA-44-180 SEMINOLE Maintenance Manual page 703

To replace grommets or eyelets, pull the conductor through the shielding sufficiently to make eyelet
accessible. Remove the eyelet being careful not to damage conductor wire. Replace grommet and eyelet using
the "AB" groove of Crimping Tool No. 11-152 or a pair of diagonal pliers modified as shown in Figure 7422.
Work the wire back into the shielding so the grommet fits properly against the ferrules in the plate. Slack in
shielding or wire can be removed by grasping the lead in one hand and sliding the other hand firmly along the
lead towards the magneto cover.
To replace contact springs, insulating sleeves, compression spring or elbows, proceed as follows:
1. Using a Bendix 11-7073 needle or a mechanical pencil with the lead retracted, hook the end of the contact
spring as shown in Figure 7423.
2. Using the needle or pencil, unscrew the spring.
3. Slide insulating sleeve and spring retainer assembly off end of lead assembly.
4. Replace defective component and reassemble as follows:
A. Fabricate a tool as shown in Figure 7424 for installing the insulating sleeves over cable terminals.
B. Slide elbow assembly over lead and attach nut finger tight to ferrule.
C. Push the fabricated tool through insulating sleeve and spring retainer assembly as shown in Figure
7425. Screw the cable terminal into the tool.
D. Work insulating sleeve and spring retainer assembly into position over the cable and unscrew the tool.
Install contact spring on cable terminal.
It may be necessary to lubricate the cable and insulating sleeve with a thin film of DC-
200 (200,000 centistokes) or commercial grade alcohol to facilitate assembly.
5. To replace one of the lead assemblies, proceed as follows:
A. Remove clamps and brackets from defective lead assembly. Cut cable ties from assembly and discard.
B. Cut the eyelet from the lead and remove grommet.
C. Grip the ferrule of the lead with a pair of vise grip or water pump pliers and with a twist-pull action
remove the ferrule from the cover and discard ferrule. Pull lead from cover.
D. Thread pre-stripped end of replacement lead through cover.
Replacement leads are available from Bendix in lengths of 17 thru 74 inches in 3 inch
increments. Use nearest next longer length to replace defective lead.
E. Scrape blue coating being careful not to cut braid for .50 of an inch from end of lead.
NEW FERRULES MUST BE USED AND INSERTED UNDER THE BRAID
EXACTLY AS STATED IN STEP F.
F. Push back braid and thread a new ferrule over wire and under braid until braid just covers knurling.
(Refer to Figure 7426.)
