Part of the New Holland Repair Manuals.
This 42-page New Holland 340-359 Service Manual PDF (OEM #40663002) delivers exact factory rebuild data for all ten grinder-mixer models. The guide details model-specific gearbox disassembly and assembly, split by serial number breakpoints to match your machine. Drive shaft rebuild sequences cover bearing cone heating, sheave installation, and end-play adjustment. Hammer mill shaft and bearing replacement instructions address every variant, including the 340 and 359. A dedicated labor guide provides flat-rate time estimates for augers, drives, hammer mills, hydraulic systems, power bale feeders, remote controls, and scale work. Gear backlash sets to 0.002"-0.015" and tapered roller bearing drag confirms at 2-6 in. lbs. (0.226-0.678 N·m). The file is fully bookmarked by section, so you can search any spec on your phone and get back to grinding.
