One page, more than 110 parts: the Valtra T 151 from the T1 series is covered here with trailer couplings, lighting, electrics and other groups.
When the temperature gauge on a T 151 creeps up under load, the hoses and thermostat are the usual place to start. This page brings together more than 110 new Valtra T 151 parts from GRANIT, Scharmüller, Walterscheid, DANA Spicer and Cobo.
There are radiator hoses, including the top hose, hose elbows, thermostats and the matching thermostat gasket. Once a hose has been replaced, bleed the system properly. Run the engine with the radiator cap off and the heater on full until the thermostat opens and the bubbles stop. A trapped air pocket around the thermostat is a common cause of a gauge that keeps wandering. Fit new clamps with every new hose and nip them up again after a few hours of warm running, because the rubber settles.
Crankshaft seals, O-rings for the oil side and seals for the lubrication line round off the engine group. A thermostat always goes in with a new gasket and the correct way round. A leaking front crankshaft seal often goes unnoticed until oily dirt starts building up on the radiator. Press a new seal in squarely with a suitable drift, never by hitting the edge directly, or it distorts and leaks straight away.
Door locks and aircon compressors keep the cab usable, which matters on a tractor with this much glass in summer. Headlights, LED headlights and work lamps light up the job after dark, and a flasher unit brings faulty indicators back to life. For towing there are drawbars and separate balls for the rail hitch. A ball with a visibly worn flank gives a knock when pulling away and braking, so replace it before the trailer eye starts to wear too. A new aircon compressor should go in with a new receiver drier, and the system needs to be evacuated before it is recharged.
Your type plate shows the exact model. With hoses, lay the old one next to the picture, since the length and bends need to match. With a hose elbow, check the diameter at both ends as well. Thermostats and compressors usually carry a number you can compare with the details shown with the item.
From the same range, the Valtra T 171 has a page of its own with the parts selected for that type, useful if both stand in your yard. For every other model from the brand, head to Valtra parts.
