Part of the New Holland Repair Manuals.
Within the hour you could be draining engine oil on your 7740 with this New Holland 7740 owner’s maintenance manual PDF open beside you: 64 pages of factory maintenance procedures, OEM part number 42564070, covering six 40 Series tractors from the 5640 through the 8340. Interval charts lay out every 10, 50, 300, 600 and 1200 hour job, from front wheel bearings and tappet clearance to fuel injectors and transmission oil. The specifications section closes the book with headlight adjustment, fuse assignments and clutch interlock settings for both 12 x 12 and 16 x 16 transmissions. Set clutch interlock cable movement between 6 and 8 mm, and spin new hydraulic filters on until the faces just meet, then a further three quarters of a turn. Some jobs it is just you, with nobody to ask. Download the bookmarked, text searchable PDF, print the pages you need, and let them get greasy on the bench before the weather turns.
