Description
When that oil pressure light starts flickering on your dash, your tractor’s trying to tell you something important. Low oil pressure is an engine killer, and this replacement oil pressure switch makes sure you get the warning before catastrophic damage happens. It’s a small part with a big job—keeping tabs on your engine’s lifeblood so you can shut things down if pressure drops too low.
What You’re Getting
- Precise pressure monitoring that matches your factory switch specs

Built for Real Farm Work
This switch works across New Holland’s entire modern tractor range, from the compact T4 series perfect for livestock chores to the powerful T6 models that handle serious row crop work. Whether you’re running a 65 HP utility tractor or a 140 HP field machine, they all use this same proven oil pressure monitoring system. That’s good news for keeping spares on hand and getting parts when you need them.
Made to Last
The heavy brass construction handles the high temperatures you’ll find around diesel engines, while the internal contacts stay reliable year after year. This switch uses a calibrated diaphragm that responds to exact pressure levels, so you get real warnings about real problems—not just nuisance alarms when your engine’s running hot at idle.
Good to Know
Installation typically takes about 10 minutes with basic tools. The switch threads directly into your engine block or oil filter housing—check your manual for the exact spot. Use thread sealant rated for oil contact, but don’t go overboard since too much can block the pressure port. Before you blame a switch for oil pressure warnings, verify your actual pressure with a mechanical gauge first. Sometimes that switch is just doing its job telling you about a real problem that needs attention.
