Part of the New Holland Repair Manuals.
From the air conditioner compressor to the Motorola and Niehoff charging circuits, this New Holland 1068, 1069, 1075, 8500 service manual PDF (OEM 40106841) works through every major system on these Automatic Bale Wagons across 242 pages: power steering, front axle, brakes, clutch, four-speed transmission, drive axle, and hydraulics. Hydraulic diagrams map circuit flow through the pressure relief valves before you crack a fitting, and wiring diagrams sort out both alternator setups. Exploded views back up the teardown procedures, with troubleshooting charts for clutch and brake diagnosis. Mic your brake linings against the 3/16 inch (5 mm) wear limit, and pull the pitman arm bolt to 160 to 180 ft. lbs. (217 to 244 N-m). Nobody wants to guess at a differential carrier rebuild mid-season. Print the sections you need and let them take grease on the bench; the bookmarked, text-searchable PDF stays clean on your computer.

New Holland 1068, 1069, 1075, 8500 Common Problems This Manual Covers
New Holland 1068 bale wagon pickup chute hydraulic motor squeals and stalls, only runs in one narrow lever position
Check hydraulic oil level and test main relief pressure; the 1068 and 1069 setting is 2000 PSI (138 bar) on page 182. Verify the control valve linkage centers the spool fully before condemning the motor. If flow tests good, pull the orbit motor and inspect the splines and rotor set for wear.
Manual Section: Hydraulic System p. 182Table one or table two lifts slowly, squeals, and stalls before reaching full up position
Check the reservoir for foaming oil and listen for pump squeal; the gear pump chart on page 195 covers both. Measure gear shaft diameter against the 0.873 in (22 mm) replacement limit on page 194. On reassembly, draw the pump cap screws up evenly to 40 ft. lbs. to 45 ft. lbs. (54 N·m to 61 N·m).
Manual Section: Gear Pump Troubleshooting p. 195Brakes squeal, pedal feels spongy, and loaded wagon pulls to one side when stopping
Pull the drums and bleed the wheel cylinders; a spongy pedal usually means air or a leaking cylinder. Replace linings worn below 3/16 inch (5 mm) and any drum over 15.12 inches (384 mm), the limits on page 75. Grind replacement shoes 0.030 inch (0.8 mm) smaller than the drum inside diameter per page 71.
Manual Section: Brakes p. 75Steering wanders on the road and gets heavy with a full load of bales
Check pump pressure against the 1500 PSI (100 bar) relief setting on page 17, then work the road wander chart on page 42. Inspect kingpin bushings and tie rod ends for slop, and set the front wheel bearing retaining nut to 50 ft. lbs. to 80 ft. lbs. (68 N·m to 108 N·m) per page 49.
Manual Section: Power Steering Gear p. 42Clutch slips under load and chatters when engaging in soft field conditions
Verify free pedal travel and check the hydraulic clutch linkage for leaks before pulling the transmission. Inspect the disc for glazing and oil contamination from a leaking rear main seal. If you replace the master cylinder, torque the mounting nut to 1550 in. lbs. to 1600 in. lbs. (175 N·m to 208 N·m) per page 87.
Manual Section: Clutch p. 87Frequently Asked Questions
What are the drum brake wheel cylinder replacement specs on a New Holland 1068 bale wagon?
If the bore of the cylinder is pitted or scratched, it should be honed or replaced. When reassembling, coat the cylinder bores with a film of clean brake fluid and ensure the rubber cups are installed with the spring centered in the cup to prevent damage to the lip of the cup. p. 72
What are the hydraulic lift cylinder replacement specs on a New Holland 1068 bale wagon?
If a piston has no deep scratches, sharp feather edges can be removed with very fine emery cloth or steel wool. However, if the difference in diameter between the piston and the tube is greater than 0.015" (0.38 mm) at any point, the piston should be replaced. p. 86
What is the correct torque for the main hydraulic pressure relief valve on the 1068 and 1069 models?
The main hydraulic pressure relief valve is set at the factory to 2000 PSI (138 bar) at 1750 RPM engine speed. p. 61
What air-conditioner compressor drive belt tension does the New Holland 1068 bale wagon need?
A belt tension of 100 lbs. (45 kg) is considered normal. The belt should deflect 1/2 inch (13 mm) when a 22 lb.-25 lb. (10 kg-11 kg) force is applied at the center of the span. p. 8
What is the front axle wheel lug bolt torque spec for the New Holland 1068, 1069, 1075, 8500 bale wagon?
The proper torque for the wheel lug bolts is 400 ft. lbs.-450 ft. lbs. (542 N-m-610 N-m). These should be checked initially at 15 hours of operation and subsequently every 50 hours. p. 50
