More than 250 parts for the New Holland TL90A, a tractor from the TL-A Series. The range includes trailer couplings, lighting and electrics, among other groups.
By the time a New Holland TL90A has done a good number of seasons, the linkage, the clutch and the cab tend to ask for attention. This page holds more than 250 parts for the TL90A from GRANIT, LUK, Eaton, Cobo and ROCKINGER.
If the linkage slowly drops with an implement on, the lift cylinder seals are the first suspect. For this tractor there are piston sealing rings and seals for the outer lift cylinder. When you change them, look closely at the cylinder bore. Scoring or pitting will chew up a new seal in no time. Clean everything, wet the new rings with clean hydraulic oil and seat them without sharp tools.
Gas struts for the roof hatch are here too. Fit them with the piston rod pointing down so the internal seal stays lubricated, and replace them as a pair if the hatch has two.
With the clutch split anyway, replacing the thrust bearing at the same time makes sense. Getting in there is the real job, the bearing itself is quick. On gear wheels the reference number is the safest guide, and if it has worn away, count the teeth and check the bore.
Further parts for the TL90A include tractor seats, an air conditioning compressor, rear lights, indicator and position lights, relays, drawbars and a ROCKINGER Piton Fix.
Check the rating plate first so you know the tractor is a TL90A. For anything beyond that, the number on the old part is what to match against this page.
If the cab only gets lukewarm air, look at the compressor belt and the clutch on its pulley first. A slipping belt or a clutch that will not engage is not necessarily the compressor's fault. If a new compressor does go in, have the system evacuated and recharged by a workshop with the proper equipment, and renew the drier at the same time.
The TL90A has three siblings, each with a page of its own: the New Holland TL70A, the New Holland TL80A and the New Holland TL100A. Every page lists only what is matched to that type, so order for each tractor from its own page. The rest of the brand is under New Holland parts.
