New Holland Parts: Find the Right One for Your Machine

New Holland spans tractors, skid steers, compact track loaders and harvesting equipment, and each line uses its own numbering convention. Finding the right part starts with identifying which line your machine belongs to, then working from the serial number rather than the model badge.

At a Glance

• Parent company: New Holland is part of CNH Industrial, alongside Case IH
• Ford connection: Ford's tractor line became Ford New Holland, then New Holland
• Tractor naming: T series, plus Workmaster and Boomer ranges
• Loader naming: L series wheeled skid steers, C series compact track loaders
• Most reordered: filters, glass, door hardware and seals
• Always order against: the serial number, not the model alone

What Types of Machines Does New Holland Build?

New Holland covers both agricultural and construction equipment, and the split matters because the two sides use different naming logic.

• Tractors: the T series spans compact through high horsepower row crop machines, with the Workmaster and Boomer ranges covering utility and compact segments
• Skid steer loaders: the L series of wheeled machines
• Compact track loaders: the C series
• Harvesting equipment: combines, balers, forage harvesters and headers

Owners frequently hold machines from more than one of these lines, and a part number from one tells you nothing about another. Establish the line first, then the model, then the serial.

How Do New Holland Model Numbers Work?

The letter prefix identifies the family and the digits rank size within it.

• T series tractors run from smaller T4 machines up through T5, T6, T7, T8 and T9, with the number rising alongside frame size and power
• L series skid steers use a number that tracks operating capacity class
• C series track loaders follow the same logic on a tracked undercarriage

Suffixes and sub designations appear within families to mark generations and specification levels. As with any manufacturer, those trailing characters frequently decide the part number, because generational updates change cab, hydraulic and engine components.

Carry the complete designation into every lookup. Searching on the base number alone returns results from machines you do not own.

Where Is the Serial Number on a New Holland Machine?

Plate location varies by line. On tractors, check the frame rail and the area around the operator platform. On skid steers and track loaders, the plate is generally inside the cab or on the frame near the operator station.

We have detailed plate location guides for the loader lines, covering exactly where to look and what to do when a plate is unreadable:

• Finding the serial number on your New Holland skid steer
• Finding the serial number on your New Holland track loader

The engine carries its own serial number stamped on the block, and engine parts including filters are ordered against that rather than the machine serial. This matters on older machines where an engine may have been replaced or rebuilt.

How Do I Look Up New Holland Parts by Model?

The most reliable route is to work backwards from the part rather than forwards from the machine. If you can read an OEM number off the component being replaced, that number is the anchor for the entire search.

When no number is legible, the sequence is:

1. Identify the line and complete model designation including any suffix
2. Record the machine serial from the plate
3. Locate the assembly group that contains your part
4. Check any serial range note attached to the listing before ordering

New Holland, like other manufacturers, applies running changes at serial numbers rather than model year boundaries. A single model can therefore show more than one valid part number, each scoped to a serial range. That is why the serial is required rather than optional.

What Are the Most Commonly Replaced New Holland Parts?

Based on our catalog data, four groups account for most New Holland part orders.

Filters. Oil, fuel, air and hydraulic elements all come due on their own schedules. Lube filters are the highest volume category, with spin on full flow designs used across many machines. Examples include the Lube Filter replacing New Holland 178562 and the Lube Filter replacing New Holland 501547.

Cab glass. Windshields, door glass and rear panes, particularly on loaders working in demolition and forestry.

Door and cab hardware. Latches, hinges, seals and gas struts. Door seals are frequently under ordered because owners replace the glass and reuse a seal that has already hardened.

Seals and hydraulic fittings, on machines that spend most of their hours on loader or implement work.

Filters like the Lube Filter replacing New Holland 503202 cover multiple applications, which is exactly why the OEM number rather than the machine model is the right way to match one.

Which New Holland Parts Interchange Across Models?

Interchange follows shared structure. Where machines use a common cab, engine or hydraulic circuit, components carry across even when the model numbers look unrelated.

Commonly shared: filters across machines running the same engine family, cab glass and door hardware where the cab shell is common, mirrors and lighting, and seals and fittings on shared circuits.

Rarely shared: undercarriage components on track loaders, which are specific to track width and machine weight, hydraulic pumps and valves, and anything altered at a generational change.

Filters are the clearest example of broad sharing. A single lube filter part number can cover machines across multiple lines because the engine, not the machine, determines fitment. The Lube Filter replacing New Holland 508129 is one of several that span a wide application list.

How Do New Holland and Case Parts Relate?

New Holland and Case IH both sit under CNH Industrial. That shared ownership means the two brands draw on common engineering in places, and some components genuinely carry across.

It does not mean the catalogs are interchangeable. Shared ownership is not a fitment rule, and assuming a Case part fits a New Holland machine because of the corporate relationship is a reliable way to order the wrong component.

The practical approach is unchanged: verify by part number. Where a component is genuinely shared, the cross reference will show it. Where it is not, no amount of corporate history makes it fit.

The Ford relationship works similarly. Ford's tractor operations became Ford New Holland and subsequently New Holland, which is why owners of older Ford tractors frequently find their parts listed under New Holland numbering. If you have a Ford tractor of that era, search both the Ford OEM number and any New Holland equivalent.

How Do I Verify a New Holland Part Fits?

Four checks catch the large majority of mismatches:

1. Read the OEM number off the old part wherever it is legible
2. Confirm the machine line, full model designation and serial from the plate
3. Use the engine serial for filters and engine components
4. Measure where dimensions decide fit, particularly glass and seals

Quality aftermarket parts are manufactured to meet or exceed OEM specifications and are generally the more economical route for filters, glass and wear hardware. Customers are responsible for verifying fitment before ordering. Send your model, serial and the OEM part number to sales@partsonline.com and our team will confirm the match. Consult a certified mechanic for hydraulic and drivetrain repairs.

Frequently Asked Questions

Where can I get New Holland parts?

New Holland parts are available through dealer channels and aftermarket suppliers. Aftermarket suppliers typically carry filters, glass, seals and wear hardware, and often stock components for older machines that dealers no longer list.

Where can I buy New Holland tractor parts online?

Aftermarket suppliers list New Holland tractor parts indexed by the OEM part number. Having the number from the component you are replacing, along with your machine serial, is the fastest route to the correct part.

Who manufactures New Holland?

New Holland is part of CNH Industrial, which also owns Case IH. The two brands share engineering in places, though their parts catalogs are not interchangeable and fitment must still be verified by part number.

Where can I buy Ford New Holland parts online?

Ford's tractor operations became Ford New Holland and later New Holland, so parts for those machines are frequently listed under New Holland numbering. Search both the Ford OEM number and any New Holland equivalent when sourcing for an older Ford tractor.

Is there a New Holland parts catalog online?

New Holland publishes parts information online, organized by machine line, model and serial range. You will need the serial number from your machine to narrow results to the parts that fit your build.

How do I read a New Holland parts diagram?

The numbers printed on an exploded diagram are callout references, not part numbers. Match the callout beside your component to the corresponding row in the parts table to find the actual part number and quantity.

Where is the serial number on a New Holland skid steer?

The plate is generally inside the cab or on the frame near the operator station. The engine carries a separate serial stamped on the block, which is the number used for engine and filter parts.

Do New Holland and Case IH parts interchange?

Some components carry across because both brands sit under CNH Industrial, but shared ownership is not a fitment rule. Verify any cross brand substitution against the part number rather than assuming it fits.
