Tool Facilitates Installation of Marmon Clamps 
The problem: 
To design a tool to facilitate the installation of 
Marmon clamps. These clamps are abundantly used 
on the cold insulation lines of an F-i engine and on 
the heat exchanger lines of a Saturn stage engine. 
The modified pliers which were used were not satis-
factory because they required 2 men and about 20 
minutes to force the clamp and hold it in alignment 
while attaching the connecting screw. 
The solution: 
An installation tool that provides sufficient mechani-
cal advantage to force the clamps into place, permit-
ting one-man operation. The tool is adjustable for a 
wide range of sizes.
How it's done: 
The Marmon clamp installation tool consists of two 
handles which provide the major leverage, and a 
pivoting irm with a slot to enable snap-out action. In 
use, the tool is physically located outside the clamp 
working area and features an off-center-shift locking 
mechanism.
