In need of parts for the New Holland T4030? This T4000 series page lists more than 200 items, trailer couplings, electrics and lighting being a few examples.
The New Holland T4030 is the tractor that gets used every day for feeding, shunting trailers or taking the mower down the road. On a machine like that you want it to fire up first time and you want the lights to work. This page lists more than 200 New Holland T4030 parts, including makes such as GRANIT, ROCKINGER, Cobo, Walterscheid and LUK.
There are standard starter motors and gear reduction starters for the T4030, together with relays and micro relays in the starting circuit. Before swapping a starter, check the battery terminals and the earth strap between engine and chassis, because a corroded earth sounds exactly like a tired starter. If the relay clicks but the engine does not turn, the starter itself is the likelier cause. When choosing a new one, compare the number of teeth and the direction of rotation with the unit that comes out.
For road travel there are indicator and position lights, rear lights and mirrors. A gas strut for the windscreen keeps the screen properly open on warm days. Replace the struts as a pair so both sides push equally.
In the driveline there are thrust bearings for the driving clutch, including LUK parts. If the clutch is apart anyway, a new thrust bearing goes in at the same time. For the rear linkage there are lifting shaft seals and complete seal kits, and at the back you can fit an automatic drawbar, Piton Fix, adapter plates and a flange hitch.
A flange hitch needs a different kind of care than a pin-type drawbar. When fitting it, make sure the flange sits flat against its mounting and tighten the bolts in a crosswise pattern. After the first few days with a heavy trailer, go over them again, because a new joint can still settle.
The T4030 sits in the T4000 series. The type plate confirms you are working on a T4030, and the old part often still carries a reference number that lets you match the replacement with confidence. With lights, check left or right as well.
