Sorting out the electrics, hitch or lights on a New Holland TL100? This TL series page lists more than 300 parts, trailer couplings and lighting included.
Contractors and dairy farmers tend to keep a TL100 for a long time, and that is when the parts outside a normal service start to matter: an air conditioning compressor that has failed, a gear in the gearbox, an injector that no longer sprays cleanly. This page gathers more than 300 New Holland TL100 parts from makers such as GRANIT, ROCKINGER, Cobo, LUK and MAHLE.
A TL100 with working air con is a different machine in July. When the cooling stops, the compressor is not always to blame. Look at the V-belt first, because a cracked or slack belt will not drive the compressor properly. If the compressor does need replacing, have an air conditioning specialist evacuate and recharge the system with the correct amount of oil, and fit a new belt while everything is apart.
The TL100 belongs to the New Holland TL series, and the model and serial number are on the type plate. Many parts for this tractor are also used on Case IH, Fiat, Ford and Steyr models, which the product description will show. When in doubt, go by the reference number on the old part, especially for a gear wheel, a thrust bearing or an injector. With gears, the tooth count is a quick first check: count the teeth on the old one and compare with the description on this page.
With injectors it pays to test or replace the whole set together. One new nozzle next to three worn ones gives uneven combustion and a rough-running engine.
If the starter turns slowly or just clicks, do not condemn it straight away. Check battery voltage, the earth strap and the terminals for corrosion first. Only when all of that is sound and the fault remains is a new starter motor worth fitting. Disconnect the battery before touching the alternator or starter terminals.
If a smaller TL works alongside your TL100, it has its own page with the parts that fit. That saves time when you order for several tractors at once:
