🔌 Function

A spacer ring sets the correct distance and clearance between two assembled engine components, holding parts in their intended axial position. This maintains proper preload and alignment so mating components run within factory tolerance.

⚠️ Common Signs of Failure

• Visible wear, scoring or flattening of the ring faces
• Excessive end play or slack in the assembly it positions
• Fretting marks or discoloration indicating movement under load
• Distortion or cracking after removal, preventing safe reuse
• Noise, vibration or misalignment of adjacent components during operation

🛠️ Service Notes

• Record what came out and from where before dismantling; spacers set endfloat, height or alignment, and the original arrangement is the starting point for the rebuild
• Measure rather than assume — a spacer that has been in service can be worn or bedded in, so check the assembly against the procedure in the workshop manual for your engine rather than trusting the old stack
• Clean the faces and remove any burr from the shaft, bore or seat; grit or a raised edge under a spacer throws out the very dimension it is there to control
• Fit the spacer the correct way round where its faces differ, with any chamfer or radius toward the mating component, and confirm it sits flat and square
• Recheck free movement and the specified clearance or preload after the spacer is in place, before the assembly is finally closed up
