G. Pull the lead back into the cover to wedge the braid between the tapers of the cover and ferrule.
H. ProVide a back up support for the cover and sEat the ferrule using the 1 1-7074 Ferrule Seating
Tool (refer to Figure 74-27) and a mallet. Ferrule must be driven straight into the cover and fully seated.
1. Thread the pre-stripped end of conductor through grommet. Place a new eyelet on conductor
and crimp per instructions given in second paragraph of Maintenance of Harness.
6. When lead being replaced is of the elbow type, salvage the used elbow and compression springs for
installation on replacement lead. Install theseand new sleeve and contact spring(refer to Figures 74-28 and
74-29) furnished with replacement lead per instructions given in Steps I thru 4.
7. Reposition clamps and brackets and replace cable ties removed earlier. Clean the grommets. sleeves
and the inside of the cover with methylethylketone or denatured alcohol.
8. Spray grommets and sleeves with Fluorocarbon Spray, such as MS-S-122. supplied by Miller
Stephenson Chemical Co. Inc.. 16 Sugar Hollow Road. Danbury. Connecticut 06810. or equivalent.
9. Prior to seating spark plug lead terminal in plug barrel use fluorocarbon spray on spark plug terminal
insulating sleeve (refer to Figure 74-30) to prevent heat from sticking sleeve to spark plug barrel. Lightly
lubricate the shoulder of ferrule to minimize twisting of ferrule. (Refer to Figure 74-31.) Use GO-JO NO LOK
manufactured by Goger Inc.. Akron. Ohio 44309.
10. Check cam securing screw. Screw must be torqued to 16-20 inch-pounds.
11. With all high tension terminal grommets seated against the ferrules in the cover, attach the bottom
capacitor lead to the right main breaker and then the top capacitor lead to the left main breaker. Position the
cover on the magneto and secure. Torque cover screws to 30-35 inch-pounds.
12. Carefully route the high tension spark plug leads away from any hot spots such as manifolds and
sharp edges which might cause heat damage or chafing. Check leads for proper location in clamps so when
clamps are tightened the leads will not be crushed. Leads should be taut to prevent chafing due to vibration.
but not so taut as to produce undue strain or leads.
13. After all leads have been properly routed and secured to the engine, recheck all clamp securing screws
for tightness. Fasten coupling nuts to proper spark plugs and torque as specified in Chart 7402. Do not allow
ferrules to turn while torquing nuts.
