Part of the New Holland Repair Manuals.
Strip, set and rebuild the New Holland W50C, W60C, W70C and W80C Stage IIIB compact wheel loaders with this factory service manual. It is part number 47768541C, in English, dated March 2017. It covers all eight variants: the W50C and W60C in TC and ZB form, and the W70C and W80C in standard and High Speed.
Guessing gets expensive on these loaders. Fill a High Speed gearbox to the standard 1.3 L mark and you have overfilled it. The book gives you the inching valve pressures, steering relief settings, A/C charge and engine mount torque.
The teardown chapters come with hydraulic and electrical schematics, a DTC index and a special tool index. The rear axle chapter covers the TB 172 and the TB 138.5 High Speed transmissions separately.
