🔌 Function

A spacer ring establishes a precise fixed gap between two components so that clearance, end play or preload stays within specification. It also transmits clamping load evenly across the mating faces of the assembly.

⚠️ Common Signs of Failure

• Visible wear, scoring or polishing on the contact faces
• Flattening, distortion or cracking of the ring
• End play or clearance measuring outside specification during assembly
• Corrosion or pitting of the ring surface
• Knocking, vibration or unusual movement in the assembly it locates

🛠️ 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
