Description

If you’ve noticed your lights dimming when you rev the engine down or your battery struggling to stay charged, your dynamo pulley might be the culprit. This pressed steel pulley is what connects your engine’s power to the generator system that keeps your MF 35 or 135 running strong. When the original starts to wobble or wears out of round, you’ll know it by the belt squeal and weak charging—problems that’ll leave you stranded if you don’t fix them.

What You’re Getting

Heavy-duty pressed steel construction that handles the constant vibration and belt tension without cracking
Precision 107mm outer diameter ensures your belt runs true and your generator spins at the right speed
Properly sized 15mm center bore fits snug on the generator shaft—no wobbling or slipping
Works with the standard half-inch V-belts that came on these tractors from the factory

Built for Real Farm Work

These classic Massey Ferguson tractors work hard – from running a bush hog all day to powering hydraulic loaders in the winter cold. The original dynamo systems struggled to keep batteries charged, especially when running lights or other accessories. This pulley ensures your Lucas generator can deliver the power you need to keep the battery topped off and the lights bright during those long days in the field.

Made to Last

Farm life is tough on electrical components, and dynamo pulleys take a beating from constant belt tension, engine vibration, and weather exposure. This pressed steel construction holds up better than cast alternatives that can crack under stress, while the corrosion-resistant finish keeps it looking good and working properly season after season.

Good to Know

This is a direct replacement that mounts to your generator shaft using the existing key and hardware. Make sure your belt tension is right—too loose and it’ll slip, too tight and you’ll wear out bearings. A good rule of thumb is about half an inch of deflection when you press down on the belt between pulleys.
