Description
When you’re rebuilding an engine or doing valve work, you’ll need these small but critical valve locks to secure your intake and exhaust valves properly. These locks sit at the top of each valve stem and keep the valve spring retainer in place—without them, your valves won’t stay put and your engine won’t run. This set of 8 gives you exactly what you need for a typical valve job.
What You’re Getting
- Complete set of 8 valve locks made from hardened steel for long-lasting durability
- Precision-machined to exact specifications for proper valve stem fit
- Key-type design that locks securely into valve stem grooves
- Heat-treated construction that handles the constant stress of valve operation
Built for Real Farm Work
These valve locks fit Massey Ferguson tractors and are designed for the demanding conditions of agricultural engines. Whether you’re overhauling the engine on your utility tractor or doing maintenance on a row-crop machine, proper valve locks are essential for keeping everything running smoothly through long days in the field.
Made to Last
Engine valve locks take a beating from constant compression cycles and high temperatures. These TISCO locks are built from quality materials that resist wear and maintain their grip on the valve stems season after season. The precise machining ensures they fit properly the first time and stay secure under load.
Good to Know
Installing valve locks requires special valve spring compressor tools—don’t try to do this job without the right equipment. Make sure your valve stems are clean and free of burrs before installation. Always replace locks in sets rather than mixing old and new ones. If you’re doing a complete valve job, now’s also the time to check your valve guides and springs.
