UPPER HOSE FOR DAVID BROWN 1490, 1494 K201747

This upper hose (part number K201747) is designed for David Brown 1490 and 1494 tractors. To select the correct cooling system part, the key factor is identifying the model and connection dimensions. In this case, the inner diameter of 38/51 mm serves as a useful reference for comparing the part with the one currently installed before placing an order.

An Upper Hose That Must Be Identified Precisely

On a tractor, an upper hose is part of the cooling system and connects components of the system according to the machine’s specific configuration. This family of parts must be selected carefully, as compatibility depends not only on the part’s name but also on its shape and the diameter of its ends.

Part number K201747 corresponds to a hose designed for specific applications. The 38/51 mm inner diameter helps confirm the correct selection when the original part is removed or accessible for inspection.

Known applications on David Brown tractors

This upper hose is suitable for the following models:

• David Brown 1490
• David Brown 1494

If your tractor is one of these two models, part number K201747 is a direct replacement. However, do not assume compatibility with other David Brown models without first performing a visual and dimensional inspection, even if the part designation appears similar.

Points to Check Before Ordering

Before replacing a coolant hose, compare the old part with the new one based on three simple factors: the overall routing of the hose, the type of connection, and the inner diameter at both ends. For this part number, the value 38/51 mm indicates a difference in diameter between the two ends—an important detail to avoid installation errors.

A hose that is worn, cracked, deformed, or leaking generally needs to be replaced. During the repair, it’s also helpful to inspect the condition of the clamps and the cleanliness of the connection surfaces to ensure a proper fit.

A Useful Part Number for Routine Maintenance

On tractors in service or undergoing restoration, the upper hose is one of the parts that should be checked regularly. A clearly identified part number saves time during maintenance and minimizes selection errors associated with a generic designation.

If you’re looking for an upper hose for a David Brown 1490 or 1494, use part number K201747 and the inner diameter of 38/51 mm to confirm your selection with the existing part in place.

FAQ — Frequently Asked Questions

What is the purpose of an upper hose on a David Brown tractor?

An upper hose is part of the cooling system. It connects two components of the system depending on the tractor’s configuration, which is why it’s important to verify the part’s shape and the 38/51 mm inner diameter when identifying it.

Is part number K201747 compatible with the David Brown 1490 and 1494?

Yes, this part number is suitable for David Brown 1490 and 1494 tractors. To confirm your selection, also compare the old hose with the new one, checking the hose route and the two specified inner diameters.

How can I verify the 38/51 mm inner diameter before ordering?

Check both ends of the removed hose or the connection flanges. In this case, the part has an inner diameter of 38/51 mm, which corresponds to a hose with two ends of different sizes on the relevant circuit.

When should an upper hose be replaced?

An upper hose is generally replaced when it shows cracks, hardening, leaks, or deformation. On an older tractor, it is also helpful to check the condition of the clamps and connection surfaces at the time of replacement.
