Description
When your hydraulic system starts acting sluggish or you notice metal shavings in the filter, there’s a good chance it’s this coupling that’s giving out. This pump coupling connects your engine’s power to the hydraulic pump on your Massey Ferguson 4200 and 4300 series tractors, and when it fails, your entire hydraulic system suffers. A worn coupling can cause pump damage, inconsistent hydraulic pressure, and those frustrating moments when your loader won’t lift or your remotes won’t respond when you need them most.
What You’re Getting
- 80mm diameter with 20-spline design for precise fit and maximum torque transfer
- Heavy-duty construction built to handle the continuous load of hydraulic pump operation
- Direct replacement that restores proper pump alignment and smooth power transmission
- Compatible with both 4-cylinder and 6-cylinder engine configurations in these tractor series
Built for Real Farm Work
This coupling fits Massey Ferguson 4200 series tractors from the 4215 through 4270, and 4300 series models from 4315 through 4370. Whether you’re running your 4270 for heavy field operations or using your 4320 with implements that require precise hydraulic control, this coupling keeps your system working smoothly. These are the workhorses that power everything from front-end loaders to three-point implements.
Made to Last
Farm hydraulics take a beating from constant pressure changes, temperature swings, and the vibration that comes with heavy implement work. This coupling is manufactured to handle those stresses without the premature wear you get from cheaper alternatives. The precision-machined splines maintain their grip even after thousands of hours of operation.
Good to Know
Installation requires removing the hydraulic pump, so plan on draining some fluid and having a few hours set aside for the job. While you’ve got things apart, it’s smart to check your pump drive shaft and replace any worn seals. Make sure to use clean hydraulic fluid when reassembling, and inspect the old coupling for signs of unusual wear that might indicate other system problems.
