Description
You know that rattle you've been hearing from the engine bay? Often it's not the manifold itself - it's loose exhaust bolts vibrating against worn-out washers. This exhaust lock washer keeps your manifold bolts and studs tight and secure, preventing those annoying sounds and potentially serious exhaust leaks.
What You're Getting
- Split-ring design that grips under the nut to prevent loosening from vibration
- Heat-resistant steel construction that won't weaken from exhaust temperatures
- Precise sizing ensures proper contact with both the nut and manifold surface
- Durable finish resists corrosion from exhaust gases and moisture
Built for Real Farm Work
Exhaust manifolds take a beating on working tractors - constant heating and cooling cycles, road vibration, and the stress of hard work all conspire to loosen those critical mounting bolts. This lock washer goes under the nuts on exhaust manifold studs, keeping everything tight even when your tractor's bouncing through rough fields or working at high RPM for hours.
Made to Last
Regular washers flatten out under heat and pressure, losing their grip. This lock washer is built from spring steel that maintains tension through thousands of heat cycles. The split design means it keeps working even as bolts and studs expand and contract with temperature changes.
Good to Know
Always replace lock washers when you remove exhaust hardware - once they're flattened, they won't do their job properly. If your manifold bolts have been coming loose regularly, worn washers are likely the culprit. Use a thin coat of anti-seize on the stud threads to make future maintenance easier, but keep it off the washer contact surfaces.
