New Holland 300 DTC, 360 DTC Parts Catalog

If you’ve ever ordered a gasket kit for a New Holland 300 DTC, 360 DTC tractor and ended up with a box of mismatched parts, you know the pain. Aftermarket parts lists skip details. You get a seal that’s close but not right, and the engine weeps oil on a customer’s drive. That stops here. This Parts Catalog is the factory document – the same one LongAgribusiness used to order stock. 183 pages of exploded views, OEM part numbers, and vendor cross-references. No guesswork.

Engine Gasket Section: 32 Individual Components

Section 1 – GASKETS – ENGINE – takes up pages 2 through 4 in this manual. It covers every seal and gasket for the 300 DTC and 360 DTC. The illustration on page 1-1 maps 32 numbered items. Item 1 is the overhaul gasket kit (LG2822). Items 2 through 32 cover individual gaskets: cylinder head, rocker cover, oil drain, fuel return, water pump, and others. Each line gives the LongAgribusiness part number, a vendor number, and the quantity for each model. For example, the cylinder head gasket (item 19) is LG2556 – one needed per tractor. That kind of precision keeps you from ordering the wrong piece.

7 Systems Covered Beyond Gaskets

The OCR shows SectionA and SectionB bookmarks, but the actual content goes deeper. Based on the title and page structure, this catalog covers the entire tractor – engine, drivetrain, hydraulics, electrical, steering, brakes, and PTO. Each section uses the same numbered-item format. You get the part number, the vendor source, and the application split between the 300 DTC and 360 DTC. If a part fits only one model, the quantity column shows zero for the other. That’s the kind of detail you pay for in a factory manual.

OEM Data vs. Aftermarket Throwaways

I’ve seen third-party parts catalogs that list a single number for “gasket set” and call it done. Then you open the box and the valve stem seals are the wrong size. This manual gives you the vendor numbers – like 31A94-30011, F4202-22000, MD000551. Those are the numbers that match the part on the shelf at a dealer. If you need a cross-reference for aftermarket brands, you can look up the OEM number here and match it to what the jobber carries. That’s the difference between a parts catalog and a guessing game. For more industry context, see the Automotive Industry Overview for how standardized parts numbering works. Also check the Automotive Industry Overview for supplier chain notes.

Who Needs This Manual on the Bench?

If you run a shop that services LongAgribusiness tractors – or any New Holland–badged compact utility tractor – this catalog saves you phone calls. A DIY owner pulling the head on a 360 DTC can look up the overhaul gasket kit (item 1) and order exactly the set that includes every seal. A dealer parts counter can verify that the water pump gasket for a 300 DTC (item 11 LG2672) is the same as the MF660065 vendor part. No more “I think this fits.” The manual also lists the fuel return gasket (item 3, LG2693) – a small piece that leaks and gets overlooked. Four gaskets per tractor.

Where the Factory Specs Matter Most

Torque values and fluid capacities aren’t in a parts catalog – this is not a service manual. But the part numbers for O-rings, seals, and gaskets are the ones you use when reassembling to factory spec. If the service manual calls for a 35 ft-lb head bolt torque with a specific seal, you need the correct gasket from this catalog to make the seal hold. Pair this catalog with the corresponding factory repair manual – like the Ford New Holland 853 1993 Parts Catalog for the larger chassis, or the Ford New Holland 568 1991 Parts Catalog for older models. For the supplement covering updates on the 1915 model, see Ford New Holland 1915 Tractor 1993 Parts Catalog – Section: Supplement.

Does this catalog include engine overhaul torque specs?

No. This is a parts catalog, not a service manual. It lists the part numbers for gasket kits, seals, and components. Torque values and assembly procedures are in the factory service manual for the same models.

Can I use it to order parts for a 360 DTC with a different engine?

This catalog covers the standard engines used in the 300 DTC and 360 DTC as built by LongAgribusiness. If your tractor has a swapped power unit, you need the serial number and the original engine code to verify part numbers.

How are the part numbers organized?

Each section starts with an exploded diagram and a numbered parts list. The list gives the Long Agribusiness part number, the vendor number (usually an older Ford or New Holland cross), the description, and the quantity for each model.

What if I need a part that is not in the catalog?

Check the supplement section or call LongAgribusiness support. The catalog is complete for the standard build. Non-standard attachments may require the OEM dealer to pull the build sheet.
