New Holland TN60DA-TN95DA Series Common Problems This Manual Covers
The engine cranks well but starts hard, runs rough or smokes.
Test before you replace. A compression test comes first, and the manual notes that no more than 3 bar difference between cylinders is acceptable, so it tells you straight away whether the fault is mechanical. If compression is even, move to injection: start of delivery is 12 degrees before TDC, and the engine section gives the pump timing procedure, the injector settings and the fuel circuit bleeding routine. Check the valve clearances at 0.30 mm cold on both valves while you are in there.
Manual Section: SECTION 10 - ENGINEThe three-point lift is slow, will not hold a load, or the remotes fade as the oil warms.
Work the hydraulic section in order. It splits the tractor into a high-pressure and a low-pressure circuit and gives the pressure test procedure for each, so you can tell a tired pump from a lift control that has drifted out of adjustment. It then covers the pump, the lift with its draft, position and float controls, the remote control valves and the three-point linkage, with the test points and the overhaul procedures for the pump and the lift housing.
Manual Section: SECTION 35 - HYDRAULIC SYSTEMAn electrical fault, a dead circuit, or four-wheel drive that will not engage.
Find your build first. The electrical section draws the schematics and connector views separately for the different option combinations, because a tractor with Auto FWD and a cab is wired differently from a plain two-wheel-drive machine. Trace the circuit to the connector and test it there rather than replacing parts. The electrohydraulic FWD engagement itself lives in the transfer box section, so an engagement fault can be followed from the switch through the harness to the clutch.
Manual Section: SECTION 55 - ELECTRICAL SYSTEMFrequently Asked Questions
Which tractors does this manual cover?
The TNDA and TNSA series: TN60DA, TN60SA, TN70DA, TN70SA, TN75DA, TN75SA, TN85DA and TN95DA. The chassis, transmission, front-wheel drive, hydraulic, brake, cab and electrical work is common across the series. The engine specification chapter tabulates the 3-cylinder 2931 cm3 engine as fitted to the TN60, TN70 and TN75, naturally aspirated on the TN60 and turbocharged on the TN70 and TN75.
Does it include the full wiring diagrams?
Yes. The electrical section runs from page 1199 to page 1444 with the wiring schematics and harness connector views drawn for the different build combinations, along with the starting and charging systems, the starter motor and alternator overhauls, the instruments and lighting, the fuses and relays, and the circuit test procedures.
What power does each engine make?
All at 2300 rpm: the TN60DA and TN60SA make 57 hp gross and 55 hp net from a naturally aspirated 17:1 engine, the TN70DA and TN70SA make 70 hp gross and 67 hp net, and the TN75DA and TN75SA make 75 hp gross and 72 hp net. The TN70 and TN75 are turbocharged, which is why their compression ratio drops to 16.5:1. Bore is 104 mm and stroke 115 mm across all three.
Are the injection and valve settings in here?
They are. Valve to rocker arm clearance is 0.30 plus or minus 0.05 mm on both intake and exhaust with the engine cold, and 0.45 mm is used for the timing check. Injection pump start of delivery is 12 degrees before TDC. The engine section carries the pump timing procedure, the injector settings, the bleeding routine and the special tools for each.
How big is the manual and can I search it?
It is 1474 pages in English, a searchable and printable PDF. Search the text, print the pages you need for the bench, and keep the rest on a laptop in the workshop.
How quickly can I access this New Holland TN60DA, TN60SA, TN70DA, TN70SA?
You get a 1474-page searchable PDF (61 MB) that downloads instantly after checkout. Open it on your laptop, tablet, or phone, and bring it right to the shop floor.
Am I able to print pages from this New Holland TN60DA, TN60SA, TN70DA, TN70SA?
Yes, print as many copies as you want, and there are no restrictions. Many mechanics print the section they need and bring it to the shop floor.
