Part of the New Holland Repair Manuals.
If it says 1037 on the side of your bale wagon, this New Holland 1037 service manual PDF applies: 164 factory pages under OEM ID 47816352, running from the PTO drive shaft through every hydraulic circuit on the machine. Hydraulic schematics map the bale loading, storing, and unloading circuits, so a drifting first table cylinder or stalled push-off feet can be traced valve by valve. Full teardown, inspection, and bench-test procedures cover both the Parker Hannifin and Cessna pumps, with exploded views of the spring-centered control valves and orbit motor. Before resealing a cylinder, check piston grooves against the 0.38 mm (0.015 in) wear limit and the clevis pin hole against its 2.4 mm (3/32 in) allowance. Hay down and the table won't lift: a bad afternoon. Bookmarks and a live text layer take you straight to the circuit at fault before the weather turns.

New Holland 1037 Common Problems This Manual Covers
New Holland 1037 hydraulic pump stalls under load when second table lifts bales to fourth and fifth tiers
Check oil level first; the reservoir holds 39 L and a low tank starves the pump on the high tiers (page 25). Then work the first table and second table troubleshooting charts starting on page 73. The priority relief valve is factory set at 2150 psi per page 54; test it before condemning the pump.
Manual Section: Hydraulic systems troubleshooting p. 73Bale loader arm weak or slow, bales fall off before reaching the cross conveyor
Check the loader arm pivot and cylinder clevis pins for slop; replace any pin whose hole has worn more than 2.4 mm oversize (page 51). Adjust loader chain to 13 to 19 mm deflection under 4.5 kg of force per page 135, then retorque front loader arm attachment nuts to 270 N·m per page 128.
Manual Section: Bale loader installation p. 128Grinding noise from drive shaft under the hydraulic reservoir, gets louder under load
Block the wagon, remove the shields, and turn the drive shaft under the reservoir by hand; any roughness means the bearing is failing, so replace it before it ruins the shaft. Set hydraulic pump drive chain deflection to 6 to 13 mm per page 125 and cross conveyor drive chain to 3 to 6 mm per page 134.
Manual Section: Bale Wagons p. 125Second table or load rack drifts down and drops bales with control valve in neutral
Inspect the control valve spool for scoring and external leakage; a sticky or worn spool lets oil bleed past in neutral. If the valve checks out, reseal the cylinder and torque the 12 mm piston nut to at least 61 N·m per page 86. On the second table cylinder, set metering pin clearance to 1.5 mm per page 100.
Manual Section: Control valve troubleshootingRolling rack binds or shifts sideways, bales hang up moving toward the back of the load bed
Measure total side clearance at the rolling rack base; more than 3 mm (1/8 in) means worn guides, so shim or replace them per page 159. Inspect the load bed welds for cracks while you are under there, and confirm the rolling rack relief valve is set at 950 psi per page 56.
Manual Section: Bale Wagons p. 159Frequently Asked Questions
What are the metric non-flanged hardware torque specifications for the New Holland 1037 bale wagon?
Torque specifications for metric non-flanged hardware vary by size and class. For example, an M10 Class 8.8 bolt and Class 8 nut requires 48.7 N·m (36 lb ft), while an M24 Class 10.9 bolt and Class 10 nut requires 1016 N·m (749 lb ft). p. 15
What is the hydraulic system oil capacity for the 1037 bale wagon?
The total hydraulic system oil capacity is 45.4 L (12 US gal), and the reservoir tank capacity is 39 L (10 US gal). p. 53
What is the procedure for adjusting the cross conveyor chain tension?
Loosen the nut on the adjustable idler sprocket and slide it outward in the slot until the chain deflection at the midspan is approximately 3 - 6 mm (1/8 - 1/4 in) with a 4.5 kg (10 lb) force applied. Once tensioned, tighten the nut. p. 133
What is the factory pressure setting for the priority relief valve on the New Holland 1037 bale wagon?
The priority relief valve is factory adjusted to bypass at 2150 psi. p. 54
How do I adjust the bale loader height?
Adjust the hitch height to the tractor drawbar to 38 cm (15 in). Then, adjust the cylinder rod clevis to place the inner skid shoe at a distance of 76 - 89 mm (3 - 3-1/2 in) from the ground. p. 129
