PUSH-PULL CABLES - REMOVAL/INSTALLATION
1. General
A.  The push-pull cables transmit the rotary motion of the engine start and thrust shafts at the strut firewall to the left side of the engine cross shaft. Each push-pull cable is an assembly consisting of a push-pul1 cable in a flexible conduit, a telescopic unit at both the upper and lower ends, and two support brackets.
B.  The upper telescopic units are attached to cranks with rivets or preferred bolts for installation on the engine start and thrust shafts at the strut firewall. The lower telescopic units have end fittings for connection to cranks on the engine cross-shaft. The lower telescopic unit on the engine thrust push-pull cable has a fine adjustment feature, which permits precise adjustment of the cable for length.
C.  The push-pull cables are supported at three common points. Brackets on the push-pull cables attach to the lower support bracket below the firewall and to a bracket at about the 8 o'clock position on the engine. A spacer block at about the 10 o'clock position on the engine spaces and supports the cables. Additionally, the engine start cable is supported by a clamp at the 9 o'clock position on the engine. A common separator block rub strip is installed on the cables about 7-1/2 inches from the attachment brackets at the upper ends.
