Complete 6-Injector Set for Case Tractors — Keep Your Equipment Running Through Every Season

When a tractor loses power mid-field, it's not just an inconvenience — it's lost productivity and missed windows. Worn or clogged injectors are a leading cause of rough running, excessive smoke, and poor fuel economy in aging Case diesels. This full 6-piece set replaces every injector at once, restoring even combustion across all cylinders and getting your machine back to work.

Built for the Demands of Agricultural Work

• Complete Cylinder Coverage — All 6 injectors replaced simultaneously for balanced combustion and consistent power delivery
• Precision Spray Pattern — Engineered to Case tractor specs for optimal fuel atomization, efficient burn, and reduced smoke
• Reliable Under Heavy Load — Maintains stable injection performance whether you're plowing, hauling, or running PTO equipment at full draw
• High-Pressure Diesel Rated — Durable construction handles continuous high-pressure cycling across long working hours
• 100% New — Not Remanufactured — Full service life from installation; no worn nozzles, no compromised seals
• Direct OEM Replacement — Drop-in fit for listed Case models; no modifications required

Compatible Case Tractor Models

• Case 770  |  970  |  1070  |  1090  |  1175  |  1270  |  1370  |  1470
• OEM / Cross-Reference Part Numbers: 20668  |  A138322

What's in the Box

• 6 × New Fuel Injectors (20668 / A138322)

Pro tip: Replacing all 6 at once during a rebuild or major service eliminates uneven wear between cylinders — a common cause of rough idle and power loss that returns shortly after a partial replacement.
