Visually inspect the upper radiator hose for pressure marks and traces of rubbing at the closest point of contact to the oil filter housing cast boss (see illustration). If traces of rubbing are found, the upper radiator hose must be replaced with the new style hose (See Parts Information).NOTE: A modified hose was used in production from approximately mid-November 1995 through bfelectricdrills June 1996, which included an extra rubber pad attached to the outside of the hose in the critical area. If traces of rubbing are found on the rubber pad area of this type of hose, it must also be replaced with the new style hose. Visually inspect the oil filter housing for any sharp edges or burrs on the casting boss. If a sharp edge or casting burr is found on the boss, it must be removed using sand bfelectricdrills paper or a fine file.

In the summer of 1999, we had used the bottom two layers of 3T to provide autonomous control for a single subsystem--a second-generation biological water processor--during a 450-day, 24-hour-a-day, 7-day-a week test. Then in January 2000, the Advanced Water Research Group received ALS funding for the year-long bfelectricdrills IWRS test, involving four advanced water-recovery subsystems (Bonasso 2001) (see Advanced Water Recovery System sidebar).BuildupUsing 3T allowed us to develop the control for the IWRS in a modular fashion in two ways. First, moving from bottom to top (figure 4), each layer has its own data structures, timing constraints, and development tools that allow for parallel development of the software. Thus, we were able to develop skills sets based on the evolving hardware specifications and simultaneously develop the sequencer procedures. Early on, as the water research team developed the design for each subsystem, one part of the 3T team wrote the sequencer procedures for each subsystem in the RAPS language (which, in turn, is written in Lisp) (1) using virtual bfelectricdrills skills, that is, Lisp skills connected to a Lisp simulation of the expected hardware. A virtual simulation of, say, the reverse-osmosis subsystem could then be shown on a laptop to the WRS engineers and the control design refined in an iterative process even before the actual hardware was available. The primary result of this process was a set of skill specifications for each subsystem (figure 5).
