Part of the New Holland Repair Manuals.
Rebuilding a hydrostatic pump is the hardest job in this 42-page New Holland 116 service manual PDF (OEM 40011610), and the book opens with it before working back through the rest of the pivot tongue mower-conditioner. Hydraulic schematics trace oil through the master, slave, and swing cylinders, and a troubleshooting chart narrows drive complaints before you pull anything apart. Teardown procedures fill nearly half the pages, from dropping the conditioner rolls to gearbox work and sickle knife replacement, with exploded views to keep reassembly honest. Set the knife head at 0.003 in. to 0.030 in. clearance over the ledger surface, and preload the sickle shaft bearing to 2 in. lbs. to 6 in. lbs. Guess at that preload and you buy the bearing twice. Bookmarked and text-searchable, the file rides on whatever screen you carry to the barn or the windrow.
