Check the type plate first. If it says Typ 340, more than 400 parts on this page fit your Fendt 313 Vario, including lighting, electrics and trailer couplings.
The plough clunks as it lifts, or an implement that visibly sways behind the tractor: on a Fendt 313 Vario with plenty of hours, that is often the first sign of worn pins and bushes. This page is for the version with Typ 340 on the type plate and shows only the parts recorded for it, more than 400 in total from brands such as GRANIT, HELLA, Wabco, Sauermann and Walterscheid.
When you replace a worn pin, do the bush at the same time. A new pin in a bush that has worn oval will have the same play again before long, and the reverse is just as true. Clean the eye thoroughly before the new bush goes in, and press it in square without hammering on the edge. If the pivot has a grease nipple, pump in grease after fitting until clean grease appears at both sides. That pushes the old dirt out as well. From then on, make that grease point part of every service.
Alongside pins and bushes you will find LED work lamps and rotating beacons with holders and springs, left and right rear lights, and push button switches such as the green lighting switch. For the cab there are grab handles, rubber floor mats and gas struts for the windscreen. Around the engine there are alternators, temperature sensors and seals, and for the trailer brake line there are connector heads.
A rear light that mists up inside usually goes downhill quickly. When fitting a new one, check that the seal between lens and housing is intact and that the mounting holes line up. Do not overtighten the screws, or the housing may crack in the first frost.
If your 313 Vario carries a different Typ number, choose the page that matches it:
The Fendt 313 Vario page brings all versions together. If you are torn between two near-identical pins, the reference number on the old part decides it. The other tractors in the Fendt 300 line each have their own page as well: the Fendt 309 Vario, the Fendt 310 Vario, the Fendt 311 Vario, the Fendt 312 Vario and the Fendt 314 Vario. For everything from the brand, see Fendt parts.
