⚙️ Key Features

• OEM thickness and concentricity for the injection-pump drive

• Direct replacement for worn, distorted or incorrectly fitted spacers
• Engine type: 9.6L inline-six turbocharged industrial/generator diesel

🔌 Function

The spacer establishes the correct separation and alignment between mating fuel system components, ensuring mounting faces meet at the designed distance. Correct spacing keeps sealing surfaces square and loading even so joints stay fuel-tight in service.

⚠️ Common Signs of Failure

• Fuel seepage or weeping at the mating joint the spacer sits between
• Visible distortion, scoring or wear on the contact faces
• Corrosion or pitting affecting the sealing surfaces
• Fasteners repeatedly losing torque or the assembly working loose
• Component misalignment or vibration at the mounting point

🛠️ Service Notes

• Refit the spacer in the same position and the same way round as it came out; many spacers set an end float, an alignment or a preload and are not simply packing
• Never leave a spacer out, substitute plain washers for it, or stack washers to make up a missing one
• Keep the faces clean, flat and free of burrs and old sealant, and check the spacer itself for wear, scoring or having been drawn down out of shape
• Where several spacers or shims come out together, keep them in order and refit them in the same sequence
• Tighten the fastening to the figure given in the workshop manual for your engine, then check any clearance or end float the spacer controls
