Additional Information

The Husqvarna lawn tractor Zerk grease fitting (part number 596623501) replaces part number 539115638. This 3/8-inch fitting provides a direct way to apply grease to high-friction areas like spindle housings or steering pivots. Keeping these points lubricated helps maintain smooth operation and prevents wear that can lead to expensive repairs.

If your lawn tractor shows signs of squeaking, stiffness, or grinding from moving parts, a missing or clogged Zerk fitting could be the cause. Replacing the fitting ensures your grease gun can deliver lubricant where it's needed most.

To install, screw the fitting into the appropriate port and verify it's seated tightly. Then use a grease gun to apply lubricant until resistance increases or old grease exits the joint. Always perform lubrication with the engine off and wear gloves to protect your hands during maintenance.
