This is the compiled Caterpillar SIS repair set for the 320C and 320CL excavator, and the reason to own it is one page most sellers never mention: Cat prints wear tiers. Swing time, swing time on a slope, overswing and drift all get three numbers - new, rebuild and service limit - so you can test a machine and know exactly where it sits on its life curve. It also prints case drain flow limits for the main pump, swing motor and travel motor, which is how a professional proves internal wear instead of guessing. Coverage runs the Cat 3064 and 3066 engines with the ZEXEL fuel system, full hydraulic testing and adjusting, power train, undercarriage, and hydraulic and electrical schematics with CID/MID/FMI code definitions.
