4-CYLINDER CRANKSHAFT FOR FORD AND NEW HOLLAND, 4.4" STROKE, 76 TEETH

The 4-cylinder crankshaft for Ford and New Holland tractors is a version with a stroke of 4.4" (111.76 mm ) and a 76-tooth pinion. This combination helps identify the correct part for specific models in the 10, 600, and 700 series. When replacing an engine, comparing it to part numbers 83998218, 83998220, and F0NN6300EA provides additional verification.

The Role of the Crankshaft in a 4-Cylinder Engine

The crankshaft is a central component of the lower engine assembly. It receives the force transmitted by the pistons and converts it into rotary motion to power the entire engine. On an agricultural tractor, selecting the correct crankshaft requires careful identification, as simply labeling it “4-cylinder” is not always sufficient to distinguish between the various existing versions.

A crankshaft is typically replaced during a complete engine overhaul or after mechanical damage is discovered. In this context, the goal is not merely to find a part from the same family, but rather the specific version that matches the geometry and specifications of the engine in question.

The identifying features that allow you to identify this version

This part number is distinguished by two technical features that can be immediately used for comparison:

• stroke of 4.4", or 111.76 mm;
• 76-tooth pinion.

These specifications help rule out confusion with other 4-cylinder crankshafts. The stroke value is given in both inches and millimeters, making it easier to verify based on your workshop practices or the documentation you use. The pinion’s tooth count must match exactly on the part being removed or on the part you are looking for.

The part numbers 83998218, 83998220, and F0NN6300EA provide useful additional identification. They serve as comparison references and help confirm your selection when the engine has already been disassembled or the original part has been replaced previously.

Application on Ford and New Holland Tractors

This crankshaft is intended for Ford/New Holland tractors belonging to specific models in the 10, 600, and 700 series. This application range covers tractors from related model families, but identification must still be based on the specifications of this part number and the exact model designations listed.

On this type of engine, consistency between the tractor model, the specified stroke, and the pinion tooth count is particularly important. It is this combination of information that allows you to select the correct part without extending compatibility to other versions not mentioned.

Points to Check Before Ordering

Before confirming this part number, compare the exact tractor model with the provided list of applications, then verify the 4.4" stroke and the 76-tooth pinion. A discrepancy in any of these elements may indicate the need for a different crankshaft version, even within the same family of 4-cylinder tractors.

If the engine has ever been replaced, remanufactured, or modified during its service life, also note the part number on the removed part or in the available maintenance documentation. To select the correct part, verify the model, stroke, tooth count, and part numbers 83998218, 83998220, and F0NN6300EA before finalizing your selection.

FAQ — Frequently Asked Questions

What does the 4.4" stroke on this crankshaft mean?

The 4.4" stroke corresponds to the engine stroke value associated with this crankshaft version, which is 111.76 mm. This is an essential identification marker to avoid confusing several 4-cylinder crankshafts that look similar but differ in their geometry.

What is the purpose of the “76-tooth sprocket” specification when selecting this part?

The “76-tooth” specification is primarily used to distinguish this version from other crankshafts. The number of teeth must match exactly on your installed unit or in your comparison reference, in addition to the tractor model and the 4.4" stroke.

Does this crankshaft fit the listed Ford/New Holland tractors in the 10, 600, and 700 series?

Yes, this part number is intended for the Ford/New Holland models explicitly listed in the 10, 600, and 700 series. To confirm your selection, also check the 4.4" stroke, the 76-tooth pinion, and part numbers 83998218, 83998220, or F0NN6300EA.

Do part numbers 83998218, 83998220, and F0NN6300EA help identify this crankshaft?

Yes, these numbers are good reference points for identifying this version. They are particularly useful if you are working on an engine that has already been disassembled or rebuilt, provided you cross-reference them with the 111.76 mm stroke and the 76-tooth sprocket.
