When you’re doing engine work, those tiny valve keepers are what lock your valve stems to the springs and retainers. Lose or break one of these little split collets and your valve drops right into the cylinder—that’s a nightmare repair job nobody wants to tackle. These TISCO keepers come in pairs and are built to hold tight even when your engine’s running hard in the field.
What You’re Getting
- Split collet design grips valve stems securely without scoring or damage
- Hardened steel construction handles the constant spring pressure and engine vibration
- Comes in matched pairs so you’ve got spares when doing valve work
- Precision-machined tapered surfaces ensure proper fit in valve retainers
- Direct replacement for original equipment—no modifications needed
Built for Real Farm Work
These valve keepers work on Massey Ferguson diesel engines where reliability matters most. Whether it’s a loader tractor working the feedlot, a field machine pulling through tough ground, or a utility tractor handling daily chores around the farm, proper valve train operation keeps you running when there’s work to do.
Made to Last
Engine valve components take serious abuse from heat, pressure, and constant motion. These keepers are heat-treated to stay strong and maintain their grip on valve stems season after season. The precise machining ensures they seat properly in retainers without binding or causing wear.
Good to Know
Always replace valve keepers in pairs during engine work—if one’s worn enough to need replacing, the other isn’t far behind. Use a valve spring compressor to safely remove and install keepers without dropping them into the cylinder. A magnetic pickup tool is handy for retrieving any that slip during assembly.
