Trailer couplings, electrics and engine parts for the New Holland T7.170: more than 300 parts that fit this tractor from the T7 series, on one clear page.
A New Holland T7.170 rarely works without something on the back, be it a tipping trailer, a slurry tanker or a bale trailer. That is where wear shows up first: a worn pin, play in the slide rail or a latch that no longer locks cleanly. This page lists more than 300 parts matched to the T7.170, from the hitch system to the alternator and the cab mirrors.
For the rear hitch there are automatic drawbars, complete drawbar frames, top drawbars and Piton Fix rails. With Piton Fix you slide a ball hitch, a swinging drawbar or a clevis into the same rail and secure it with a locking pin. Height adjustable adapter plates bring the hitch to the right height for the trailer drawbar. These components come from hitch specialists such as Scharmüller, ROCKINGER, Sauermann and Walterscheid. If you run a steered trailer, parts for forced steering are here as well.
A workshop tip: give the guide and locking pin of a Piton Fix rail a thin coat of grease every so often and check the pin for wear marks. Once it stops dropping fully into its hole, the hitch knocks in the rail under load and the rail itself starts to wear faster.
On the engine side you will find alternators, multi-rib belts and belt kits with tensioner and idler pulley, oil pressure switches, sensors and intercooler air hoses. When you replace the belt, look at the tensioner at the same time. A rough or loose tensioner pulley soon ruins a new belt. A split intercooler hose often gives itself away with a hiss under load and a tractor that pulls noticeably weaker. If the oil pressure warning comes on, check the oil level and measure the pressure with a gauge before you change the switch.
Alongside these there are hydraulic cylinders, cab mirrors and tank caps, with GRANIT covering everyday wear and service items.
The quickest route is the old part itself. An alternator, sensor or cylinder nearly always carries a reference number, stamped in or on a label, and that number lets you check a replacement quickly. The type plate on the tractor confirms you are working on a T7.170 from the T7 series. For drawbars and adapter plates, the hole pattern and rail width on your tractor decide what fits.
If another T7 shares the yard with your T7.170, it has its own parts page: New Holland T7.200, New Holland T7.210, New Holland T7.220, New Holland T7.230, New Holland T7.245 and New Holland T7.260. Check the fit tractor by tractor, since details differ even within one series. Every other model from the brand is collected under New Holland parts.
