Jet Mech Pocket Toolkit

A little memorabilia from a former B-52 jet engine mechanic - the engine mechanic's pocket toolkit. Nearly every engine mechanic working the flight line was sure to have the following in his fatigue pocket.

Het Mech Toolkit

The chain and large safety pin were borrowed from a pintle hook. The small safety pin allows the chain to be attached to a belt loop. The tools are:

silver bullet
"Silver Bullet"

This important tool is needed for removing or installing an engine on the wing pod. The large end has internal threads so it may be screwed on to the shouldered bolt which secures the rear engine hanger mount. The rear engine mount consists of a curved "pork chop" bracket attached to the pod firewall and two long H-shaped beams attached to the turbine frame. Keeping the holes through all three parts in perfect alignment while working on a J-57 supported by a crane cable is nearly impossible. With this "drift" installed on the end of the bolt and a BMF hammer, the job was much easier. Because it is above the hot turbine section, the bolt will often seize and be difficult to remove. The tool is also used to knock the bolt clear of the mount holes as can be seen by its mushroomed nose. Markings are:

trim key
"Trim Key"

The little trim key is essentially a modified hex wrench with a washer attached. While most had the washer attached with common electrical solder and soon broke off, this one was attached with silver solder by some kind people at the Castle AFB jewelry hobby shop and lasted my entire enlistment. The sole purpose of this tool is to loosen and tighten the set screws which lock the trim adjustment screws on the bottom of the engine fuel control. The short end of the key is cut down because of the tight clearance where the setscrews were; an unmodified key is impossible to use.

Engine trim can only be set on a running engine. While there were motor-driven remote control units to turn the trim screws so that the mechanics could remain safely out of harm's way, the trim always "shifted" when the engine was shut down, the remote actuator removed, and the setscrews tightened. Thus most mechanics would opt to manually adjust the trim and tighten the set screws while standing under a running engine. The three trim screws were for "idle" speed, "military power", and "water injection". Words can not describe the feeling of adjusting trim while standing under a J-57 running water injection!

military bearing
"Military Bearing"

Basically a good luck token. When asked where yours was, you could always take it out and show it.
