SUBJECT: REPLACING REMOTE CONTROL CABLE INNER WIRE.
Although the cable assembly pictured, reverse side of bulletin, is the latest style, the following dimensions hold true for all previously manufactured assemblies. Proceed as follows to cut the new inner wire to the proper length and install.
1. Round the end of the new inner wire to prevent damaging the cable cork seals. (D) 2. Coat the wire liberally with OMC type "A" lubricant and insert in cable. Feed wire into cable until it protrudes from the opposite end. 3. Draw wire back until it is flush with the end of the casing brass sleeve. (A) 4. With the inner wire flush at one end, measure out 4 7/16 inches on the wire at the opposite end and cut off. (B) Round this end of the wire. 5. The inner wire is now cut to the correct length. IMPORTANT-Anneal both ends of the wire 1 to 5/8 of an inch, to permit "Kinking" on final assembly. A suggested method of annealing the ends of the wire is to grip the wire 9/16 of an inch from the end with pliers to prevent heat from creeping up the wire. Heat to a dull red quench in water. 6. Of extreme importance is the method of "Anchoring" each end of the wire in the control box rack and in the casing guide. Install one screw in each case-draw up until bottom end comes to rest against the wire then advance one complete turn. The purpose of advancing one complete turn after contact is to create a "kink" in the wire to better secure its position (one turn after contact only- be careful not to shear the wire "off"). Insert screw on opposite side and draw up tightly against the wire which is then held firmly between the ends of each screw. Before reassembling control box lubricate liberally with OMC type "A" lubricant.
The stainless steel wire is available through your parts distributor in 100 foot coils @ $10.00 list subject to your regular parts discount. Sold in 100 foot lengths only. Part No. 376971.
