This page lists more than 200 parts for the New Holland T7.175 from the T7 series, with electrics, trailer couplings and engine parts as the main groups.
When a warning light comes on in a T7.175, the culprit is often a sensor, a relay or a connector rather than anything inside the engine. That is why this page carries a good share of electrical parts alongside drawbars and mirrors. More than 200 parts fit the New Holland T7.175, supplied by GRANIT and by manufacturers including ROCKINGER, Sauermann, FEBI and MAHLE.
Only remove a NOX sensor once the exhaust has cooled down. Use a slotted sensor socket, clean the thread in the pipe and fit the new sensor with high temperature anti-seize paste. Route the cable well away from hot components and make sure nothing pulls on the plug. A cable that has touched the exhaust throws exactly the same fault code as a failed sensor, and you would be replacing a good part.
If the electric cooling fan stops running, the fan itself is not necessarily at fault. Check the fuse and the relay that switches it first. A relay takes minutes to change, while removing a fan is a far bigger job.
The cab filter deserves a look as well. After a season of mowing or baling it is clogged with dust and the ventilation moves noticeably less air.
From the outside a T7.175 looks a lot like its siblings, so note the model and serial number from the rating plate first. With sensors it pays to remove the old one and read the number on the housing, because two sensors that look identical can differ in measuring range or connector. If there is no readable number, a photo of the part and its plug helps us help you.
Within the T7 range these models have their own page: New Holland T7.170, New Holland T7.200, New Holland T7.210, New Holland T7.220, New Holland T7.230 and New Holland T7.245. If several of them run on your farm, each page shows what belongs to that exact tractor. Everything else from the brand sits under New Holland parts.
