BUILDING BETTER MOUSETRAPS

There are many examples of the ways in which Sage Parts has re-engineered and improved parts utilized in other industries and made them ramp-ready and more reliable in GSE operations. Examples include a heavy duty shifter, brake booster, a high efficiency copper/ brass radiator, an ignition switch and the Ford 300 engine, governor and carburetor. Let’s take a closer look at each of these examples.

For the re-engineered heavy duty shifter, Sage engineers have created a design featuring low friction that minimizes the abrasion and wear caused by metal parts sliding and repeatedly rubbing together. A synthetic rubber, spring-like bushing has also been engineered into the shifter’s design to withstand the most extreme environmental conditions while providing optimal UV protection, which is a major cause for the original shifter’s failure.

The Sage brake booster redesign resulted from research showing that while the original brake boosters were fine for lighter weight automotive vehicles, they were no match for GSE. To meet GSE vehicle demands, the brake booster’s pedal rod and power piston components were both redesigned to perform under higher degrees of stress. The improved power piston material and design also accommodates higher stopping loads inherent in ramp operations.

Re-engineering of the Sage high efficiency copper/brass radiator brought about several key enhancements, including a 25% increase in tank wall thickness, brazing reinforcements both internally and externally on the filler neck, the addition of two anchor points welded to both sides of the tank for more durable inlet/outlet tubes, and a re-designed mounting system, all of which contribute to a much improved, stronger and longer lasting radiator.

The creation of the improved ignition switch began with the realization that many off-the-shelf switches use steel contacts, which create an electrical current arc when subjected to a high moisture environment such as that of airport ramps. The electric arc can cause steel contacts to carbonize and create resistance, which in turn reduces current flow to the starter motor. What’s more, the steel contacts tend to “weld” together. The Sage ignition switch has been re-engineered with silver contacts that will not carbonize or weld together and contains other stainless steel internal parts to resist high moisture intrusion and failure.
