Description of Tool Usage:

The inlet cowl sling equipment is used to remove or install the nose cowl from RB211-524 engines. The B71040-39 equipment also may be used on nose cowls of 737-600 thru -900 airplanes equipped with CFM56-7 engines. The only tooling difference for the CFM56-7 and the RB211-524 nose cowls is RB211-524 engines use B71040-24 lifting strap assemblies while the CFM56-7 engines use B71040-25 lifting strap assemblies. All B71040 sling equipment allows the nose cowl to be rotated from the engine installation position to flat (inlet side up).
