DESCRIPTION:
KOMATSU PC3000-1 HYDRAULIC MINING SHOVEL SERVICE REPAIR MANUAL (SN:PC3000-1 6171) KOMATSU PC3000-1
- In this part we describe all functions; testing and adjustment procedures.Of course for better understanding of the systems the hydraulic and electric circuit diagram is very helpful and a must for fault finding.
- Whenever it is possible for the description the circuit diagram numbers / codes are used.
- One who is not able to understand the circuit diagram or is not so familiar with the used symbols should study the hints for the circuit diagrams Section 10 and 11.
Following abbreviations are used:
PDG = Pump-Distributor-Gear
LBA = Loader-Bucket-Attachment
BHA = Back-Hoe-Attachment
NIRV = Main-Relief Valve (Primary valve)
SRV = Service-line-Relief Valve (Secondary valve)
ACV = Anti-Cavitation Valve
EPM = Electronic-Power Module
ESR = Electronic-Signal Rectifier
ELL = Electronic-Load Limiter
EFM = Electronic-Fuel Measurement
DRE = Druck-Reduzierventil-Elektrisch (Pressure Reducing Valve Electrical)
EGR = Elektronische-Grenzlast-Regelung (Electronic Load Limit Regulation)
EBL = Electronic Bucket Leveling
ETM = Electronic Text and Monitoring System
CLS = Central Lubrication System
STC = Slew ring Teeth Central Lubrication System
PTO = Power Take Off
RPM = Revolutions Per Minute
All adjustments and pressure settings for the hydraulic circuits must be
carried out at normal operating temperature
For service intervals, oil levels and filling capacities see the “Service Literature”, because this literature is always made for the specific machine
