The HPU Systems were then re-installed at the Launch Site, systems and piping were flushed, and acceptance testing was performed

Phase II: 16-Drive Truck motors shall be removed, evaluated, rebuilt, full load tested to 10,000 ft lbs @ 30 RPM on our test bench. Drive wheels shall be removed and bearings inspected, lubricated and re-sealed. Forty-eight bellows shall be changed out to the new high load design. The newly refurbished 85,000 lb Drive Trucks shall be shop-flushed, proof tested, re-installed and acceptance tested.

Apex and Launch Site History: The MST Drive and Tower Lift Hydraulic Systems were originally built and designed by Paul-Munroe Hydraulics (PMH) for the Titan III program in 1966. In 1985 PMH was tasked to refurbish and upgrade the MST hydraulic systems for the Space Shuttle program. In January 1995 Apex acquired Paul-Munroe Engineering Service through an acquisition by employees David Reiniger, Harsoyo Lukito, and Todd Gallagher.
