CYLINDER GP-BUCKET 2254581 - Caterpillar

Remove wires.
Apply test pressure.
Measure the resistance of the starting air pressure sender.
Compare the measured resistance to the resistance values that are listed in Table 1.
Table 1
Test Pressure    Resistance ( 5 Ohm)    
0.0 kPa (0.00 psi)     10    
500 kPa (72.52 psi)     53    
1000 kPa (145.04 psi)     92    
1500 kPa (217.56 psi)     125    
2500 kPa (362.60 psi)     180    The results of the preceding procedure are in the following list:
The resistance is within the limits that are listed in Table 1. The starting air pressure sender is functioning normally. STOP.
The resistance is outside the limits that are listed in Table 1. The starting air pressure sender is not functioning normally. Replace the sender. STOP.
