Description
There’s nothing quite like that sinking feeling when your oil pressure warning light stays on—or worse, when it doesn’t come on at all and you’ve got engine damage brewing. Your oil pressure switch is the guardian that watches over your engine, triggering that critical warning when oil pressure drops below safe levels. When this little sensor starts acting up or fails completely, you’re flying blind on one of your engine’s most important vital signs.
What You’re Getting
- Precise pressure sensing that triggers warnings at the right oil pressure levels
- Durable construction built to handle the heat and vibration of daily farm work
- Direct replacement design that connects to your existing warning light circuit
- Quality TISCO manufacturing that meets OEM specifications for reliable operation
Built for Real Farm Work
This switch is engineered for Massey Ferguson tractors spanning decades of production, from compact utility models like the MF154S and MF174S up to larger field tractors like the MF3090 and MF3650. Whether you’re running a smaller MF240 for livestock chores or pushing a big MF3070 through heavy field work, these machines count on proper oil pressure monitoring to prevent costly engine damage. It also fits various MF industrial equipment including loaders and backhoes that see tough construction and material handling duty.
Made to Last
Farm equipment oil pressure switches take a beating from constant temperature cycling, engine vibration, and exposure to oil, dirt, and moisture. This TISCO replacement is built with quality internal components that maintain accurate switching points even after thousands of operating hours. The threaded housing provides a secure, leak-proof connection to your engine block.
Installation Notes
This is a straightforward replacement—just thread out the old switch and thread in the new one with a bit of thread sealer to prevent leaks. The electrical connection typically uses a single wire that grounds through the switch body when oil pressure drops. Make sure to check your oil level and change your filter if you’ve been having pressure issues, as a faulty switch often gets blamed for problems that are actually low oil or a clogged filter.
