This is the factory service manual for the McCormick International B-47 pickup baler, publication SM-23, running 146 pages. It is written for the mechanic overhauling or repairing the baler rather than just operating it.The manual works through the machine system by system: the hitch, driveshafts, and flywheel; the main gearbox, crank, and power train; the plunger and bale chamber; the pickup and auger drives; the axle and cross conveyor; and the full tying and twisting (knotter) mechanism. Each system includes removal, dismantling, inspection, assembly, and installation, along with the adjustments that make a baler tie cleanly.You also get baler timing procedures, bale length and density control service, torque data, spring specifications, and exploded views to guide reassembly and parts identification.

Mccormick International B-47 Common Problems This Manual Covers
Bales will not tie cleanly
Missed or inconsistent knots are the classic baler complaint, usually from knotter timing, worn bill hooks, or twine tension being off. This section covers the tying mechanism with its inspection and adjustment steps.
Manual Section: Tying and Twisting Mechanism p. 71Needle timing out of adjustment
Needles that mistime can strike the chamber or miss the knotter. The timing section covers timing the packer fingers and needles and checking the mesh of the drive gears.
Manual Section: Timing p. 114Pickup plugging or hay jams
Worn pickup teeth or a misadjusted feed can jam the crop flow at the pickup. This section covers the pickup, auger, and their drives for inspection and repair.
Manual Section: Pick-Up, Pick-Up Auger and Drives p. 51Rough or loose plunger drive
Excess play, knocking, or heat in the plunger area points to worn plunger bearings or the pitman and crank bearing. This section covers the plunger and bale chamber teardown and inspection.
Manual Section: Plunger and Bale Chamber p. 39Gearbox oil leaks
Oil seepage around the gearbox usually means failed seals or worn components. The transmission and power train section covers gearbox removal, inspection, and reassembly.
Manual Section: Transmission and Power Train p. 27Inconsistent bale length or density
Bales coming out too loose or uneven in length trace to the length and density controls. This section covers the manual and hydraulic density control, the relief valve pressure, and their adjustments.
Manual Section: Bale Length and Density Controls p. 118Frequently Asked Questions
