Part of the New Holland Repair Manuals.
A W230C throws a transmission temperature fault halfway through a stockpile shift, or one bucket function quits while the lift arms still work. This is the New Holland service manual for the W190C and W230C Tier 4A (interim) wheel loaders, part number 47673351.
It covers builds with the 4-speed and the 5-speed transmission, plus both XT and Z-Bar linkage. Inside are the engine with SCR and EGR/DPF aftertreatment, powershift and torque converter stall testing, axles and brakes. It also has full hydraulic schematics, electrical frames 01 to 33 and fault codes for the ECU, RCU, transmission and cluster.
The loader valve relief settings, brake accumulator cut-in and cut-out pressures and tire pressures for both models are printed in their sections, next to the procedures that use them.
