![New Holland Boomer 40 / 50 Rops Repair Manual [Compact Tractor]](https://youfixthis.com/wp-content/uploads/2012/02/Manual_Download-300x300.jpg)
Part of the New Holland Repair Manuals.
This is the factory service manual for the New Holland TC5.80, TC5.90 and TC5.90 Hillside combines, Tier 4B, part number 48001074. It works through the machine the way New Holland builds it, then follows the crop path from header attachment through feeding, threshing, separation, residue handling, cleaning and unloading. Read one thing before you diagnose the hydraulics: the machine carries two pumps without lateral flotation and three with it, so the circuit in front of you depends on how your combine was specified.

New Holland TC5.80, TC5.90, TC5.90 Hillside Common Problems This Manual Covers
Hydraulic pressures do not match the figures you expect.
Confirm the pump count before you conclude anything. A combine without lateral flotation has two pumps and one with it has three, and the third circuit is limited to 230 bar rather than the 280 bar of the main and steering pumps. Measure the main pump against 48 l/min at up to 3000 rpm and the steering pump against 16.5 l/min, and remember that return oil runs at up to 1.15 bar, which is normal rather than a leak.
Manual Section: Hydraulic SystemsOn a Hillside machine the levelling is slow, drifts, or feels spongy.
Check the accumulator charges first. The lateral float circuit uses one accumulator at 120 bar and one at 85 bar, and a soft accumulator produces exactly that behaviour long before the pump or the cylinders are at fault. The hydraulic section names the accumulator control valve and the header suspension accumulator on the same circuit, so check the whole group rather than one unit.
Manual Section: Hydraulic SystemsThe machine derates or logs a fault code with no visible mechanical cause.
Read the code and go to the fault-code section, which is split between machine codes (from page 1295) and engine and aftertreatment codes (from page 2051) and carries the DTC reference and the guided diagnostic for each one. Codes from the Selective Catalytic Reduction system look like engine faults from the seat but are diagnosed through their own electrical chapter, and sensor faults such as intake air humidity have their own procedures. Follow the harness drawing to the connector the test names.
Manual Section: Electrical Systems: Engine and Aftertreatment Fault CodesFrequently Asked Questions
Which combines does this manual cover?
The TC5.80, the TC5.90 and the TC5.90 Hillside, all Tier 4B, under part number 48001074. The crop path, the drives and the electrical architecture are shared; the Hillside adds its self-levelling arrangement, which the cleaning section covers.
How many hydraulic pumps does my combine have?
Two if it was built without lateral flotation, three if it was built with it. That is stated in the pump specification and it matters before you measure anything. The main pump is a silence gear type of 16 cc per revolution giving 48 l/min (10.5 gal/min) at up to 3000 rpm, the steering pump is 5.5 cc per revolution giving 16.5 l/min (3.6 gal/min), and both are limited to 280 bar (4061 psi). The third pump, where fitted, feeds the lateral flotation circuit.
What accumulator pressures does it specify?
Two lateral float accumulators, one charged to 120 bar (1740.0 psi) and one to 85 bar (1232.5 psi). The hydraulic section also names the header suspension accumulator and the accumulator control valve, and it notes that return oil from the hydraulics runs at up to 1.15 bar (17 psi).
Does it cover the SCR emissions system and the fault codes?
Yes. Selective Catalytic Reduction control has its own electrical chapter alongside the climate, sieve and reverser controls, and the fault-code section runs from page 1295 to page 2626, split between the machine codes and the engine and aftertreatment codes with DTC references and a guided diagnostic behind each code, down to individual sensors such as the intake air humidity sensor.
How big is the manual and can I search it?
