Description
That ticking sound from your engine bay isn’t just annoying—it’s exhaust gases escaping where they shouldn’t be. A blown exhaust manifold gasket might seem minor, but it robs power and can let dangerous fumes into your cab area. This high-temperature gasket seals the connection between your David Brown’s manifold and engine head, stopping leaks that affect performance and can lead to warped manifolds if ignored.
What You’re Getting
- High-temperature material that withstands extreme exhaust heat without breaking down
- Precision-cut design for exact fit on David Brown models—no trimming or modifications needed
- Composite construction that provides reliable sealing under pressure and vibration
- Crushable design that conforms to minor surface irregularities for a tight seal
- Multi-layer build that resists deterioration from heat cycling and engine vibration
Built for Real Farm Work
Your David Brown produces serious exhaust temperatures, especially when working hard pulling implements or running PTOs at full throttle. Whether you’re operating an 850 for loader work, running a 990 with a plow, or pushing a 1690 through harvest season, the exhaust manifold sees extreme heat cycles from cold starts to full operating temperature. Add in the constant vibration from diesel combustion, and it’s easy to see why these gaskets eventually fail.
Made to Last
This gasket uses materials specifically chosen for exhaust applications that maintain sealing integrity through thousands of heat cycles. The composite construction provides enough compliance to seal minor imperfections while remaining stable at high temperatures. The multi-layer design prevents blow-through even under high exhaust pressure during heavy loads.
Installation Notes
Proper installation is critical for exhaust gaskets—clean both surfaces thoroughly using a gasket scraper, not a grinder, to avoid removing metal. Check for warping with a straight edge since a warped manifold won’t seal regardless of gasket quality. Install dry unless specifically instructed otherwise, as exhaust sealants can actually cause failures. Tighten manifold bolts in sequence from center outward to specified torque, and plan to retorque after the first heat cycle as gaskets compress slightly.
