troubleshooting in the heavy equipment engine system HD 465-7 & HD 465-7R
MACHINE INSPECTION PROGRAM
Describe the purposes and objectives as well as measurement procedures (examination):
Engine Speed :
Finding out the speed engine during the low idle and highhead, to ensure Fuel system and water system
normal, measured at fan radiator using tool tachometer or monitoring code on the panel monitor.
‐ Low idle Lo : 750 ± 50 rpm
‐ Low idle Hi : 945 ± 50 rpm
‐ High idle Power mode : 2,270 ± 50 rpm
‐ High idle Economy mode : 2,200 ± 50 rpm
Measurement condition:
‐ Engine coolant temperature : in a operating range
‐ Torque converter oil temp.: in a operating range
‐ Hydraulic oil temperature : 45 – 55 °C
, Procedure
1. Preparation of work
‐Positioning ON goes and set a monitor machine (EMMS) on "Monitoring function of service
"fashion" as a preparation to measure the engine speed.
‐Monitoring system : ENGINE
‐Monitoring code : 01002 (SPEED ENGINE)
2. Low IDLE test
‐ Position the lever shift in "N" and LEVER on HOLD.
‐ Alive the engine and measure the speed engine without stepping on accelerator handle.
3. Testing high idle speed
‐Position the lever shift in "N" and lever HOLD.
‐Establish an engine and measure the speed engine with full step accelerator on the handle
Compression pressure
To determine the amount of air pressure in the combustion chamber when the piston moves from TMB –
TMA, as
indications of a piston leak and wear cylinder liner wear and wear. Measured at hole injector as crank
engine.
‐ HD465 ‐ 7R : min. 30 kg/cm 2 (2.94 Mipa)
‐ HD465 ‐ 7 : min. 30 kg/cm 2
kondition measurement
‐ Engineer : 40 – 60 ° C
‐ Speed Engine : 210 - 250 rpm
Procedure
‐ Dismounting injector is in cylinder head.
‐ Connect and gauge in cylinder which will be
