MAINTENANCE MANUAL
(3) Remove the insulator sleeve from the end of the wire.
(4) To remove a lead from the M-1568 Harness Cap, use diagonals or cutting pliers and cut the
lead off close to the housing. A drift or punch can be used to tap the ferrule loose from the
housing.
NOTE: Further service on the Slick harness wires require the use of Slick M-1495 Service
Tool Kit, obtained from:

E. Assembly
(1) Cut a piece of harness wire to the length required. Do not stretch the wire when measuring it.
(2) On the magneto end, make a final mark 0.75 inch from the end of the wire. A 0.937 inch mark
should be made from the spark plug end of the wire.
(3) Flare out shielding, then without allowing any of the shielding to fold under, insert Slick M-
1743 Stripping Tool under the braided shielding (refer to Figure 1).
(4) Make sure the stripping tool is inserted past the cutting mark, then cut the shielding with a
sharp knife using a rolling motion and remove the shielding and stripping tool. Take care not to
cut the silicone insulation (refer to Figure 2).
(5) Cut exposed insulation 0.062 inch back from end and roll the insulation clockwise to remove it.
Do not pull the insulation off the wire. Trim the end of the coiled conductor to make a clear hole
for inserting the stud (refer to Figure 3).
(6) Using M-1742 Pin Vise, insert M-1741 Drill (72 drill), drill out the silicone rubber from inside of
coiled conductor approximately 0.375 inch deep (refer to Figure 4).
(7) On spark plug end of wire install M-1462 Nut followed by M-1459 Female Taper Hex Ferrule
(refer to Figure 5).
(8) After installation of nut and ferrule, bend and rotate the silicone insulation as illustrated in
Figure 6 to flare out the shielding so a drive ferrule can be inserted. Take care not to cut the
silicone insulation with the sharp braiding while the wire is being rotated (refer to Figure 6).
(9) On spark plug end of wire install M- 1458 Male Tapered Drive Ferrule over silicone insulation
and under shielding to within 0.062 inch from flange of ferrule. Make certain that shielding is
away from ferrule flange then slide Ferrule M-1459 over the M-1458 Drive Ferrule until tight
(refer to Figure 7).
NOTE: Do not reuse the M-1458 Drive Ferrule.
(10) For spark plug end, mount M-1747 Drive Plate in a bench vise. Set the hex ferrule in the slot of
the drive plate. Drive the M-1458 Drive Ferrule flush against the hex ferrule using the M-1744
Drive Tool (refer to Figure 8).
(11) For magneto end of wire, insert wire through approximate hole in the M-1568 Harness Cap so
the shielding is through the hole as shown in Figure 9.
(12) Install an M-1458 Male Tapered Drive Ferrule over insulation and under shielding as in Step
(9), then drive the ferrule into the M-1568 Harness Cap using the M-1744 Drive Tool, similar to
Step (10) (refer to Figure 10).
(13) Clamp the threaded end of the M-1498 Electrode Screw in the M-1742 Pin Vise. Insert the
tapered pin of the electrode screw into the center of the coiled conductor by turning the pin
vise counterclockwise and pushing at the same time until the screw is flush with the insulation.
This is done at both ends of the wire assembly (refer to Figure 11).
