Description
If you’re dealing with hydraulic fluid seepage around your pump or noticing drops on the ground where you park, a failing pump gasket is likely the culprit. When hydraulic systems start leaking, you lose pressure and performance – and that means your three-point hitch, loader, and power steering won’t work like they should. This gasket creates the seal between your hydraulic pump and its mounting surface, keeping fluid where it belongs and maintaining the pressure your tractor needs.
What You’re Getting
- Precision-cut gasket that matches the original equipment specifications exactly
- High-quality material that withstands hydraulic system pressure and temperature cycling
- Direct replacement for your Case IHC 684 or 784 – no modifications needed
- Designed to handle the constant pressure changes that come with normal tractor operation
Built for Real Farm Work
Your Case IHC 684 and 784 tractors from the popular 84 series are workhorses that handle everything from loader work around the farmstead to field operations with hydraulic implements. These mid-size tractors rely on their hydraulic systems for three-point hitch operation, power steering, and auxiliary hydraulics that run everything from post hole diggers to hay spears.
Made to Last
This gasket is manufactured to handle the demanding conditions of agricultural hydraulic systems. It resists the petroleum-based hydraulic fluids, temperature swings from cold mornings to hot afternoons, and the constant pressure cycling that occurs during normal tractor operation.
Installation Notes
Clean both the pump and mounting surfaces thoroughly before installation – any debris or old gasket material will cause leaks. Apply a thin film of hydraulic fluid to the gasket during installation to help it seat properly. The kit mentioned (3843K) includes additional seals if you’re doing a complete pump service.
