Part of the New Holland Repair Manuals.
Need the factory book for your New Holland BC5070 square baler? This 660-page service manual (OEM #47917636) also covers the BC5050, BC5060, BC5070 Hayliner®, and BC5080, so you're not stuck guessing which chapter applies to your frame. Inside you get hydraulic schematics for the variable displacement pump, bale density circuit, and pickup lift circuit, plus a full knotter and twister section covering timing adjustment, clutch and brake service, and needle-to-plunger timing. Set your PTO limit to the 540 RPM maximum, and torque 37° flared tube nuts anywhere from 12-16 N-m on the small sizes up to 305-325 N-m on the big ones. Chasing a knotter that won't tie is miserable work without the timing marks in front of you. This PDF carries bookmarks straight to every system, so you jump from the twister frame to the trip mechanism without flipping 600 pages by hand.
