Description

When your water pump pulley starts wobbling, making noise, or showing signs of wear, it’s time to replace it before it damages your pump shaft or fails completely. This pulley is designed specifically for MF 100 series tractors and ensures your cooling system keeps running smoothly, no matter how hard you’re working that tractor.

What You’re Getting

Precision-machined for 18.9mm shaft diameter – no wobble or vibration
Proper pulley dimensions to maintain correct belt tension and water pump speed
Durable construction that handles the constant operation of farm work
Direct replacement that bolts right on without modifications

Built for Real Farm Work

This pulley fits MF 100 series (165, 168, 175, 178, 185, 188) tractors, the versatile utility machines you see everywhere from hayfields to barn lots. Whether you’re running a brush hog, pulling a hay rake, or doing loader work, these tractors put steady demand on their cooling systems. A properly functioning water pump pulley keeps coolant circulating at the right speed to prevent overheating during those long summer days.

Made to Last

This isn’t some lightweight aftermarket part that’ll give you trouble down the road. The pulley is built to handle the belt loads and constant vibration that come with tractor work. Proper metallurgy and machining tolerances ensure it’ll keep your water pump running smoothly for years to come.

Installation Notes

Installation is straightforward – the 18.9mm bore fits your water pump shaft perfectly. Before installing, check your belt condition and replace it if it’s cracked or frayed. A new pulley deserves a good belt to work with. While you’re at it, inspect the water pump for any signs of leakage or bearing noise – catching problems early saves money and downtime.
