1586388 Spacer Washer | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta spacer washer is a replaceable locating, spacing or bearing-support component used in the inlet and exhaust support bracket. It is manufactured to the original Volvo Penta dimensions and interface requirements so the supported component retains the specified clearance, spacing and location. In service, it sets the required spacing and load distribution at the inlet/exhaust support bracket fastener. Fitment is controlled by the exact engine or product configuration and serialised parts list; confirm OEM number 1586388 against the installed assembly before ordering.

🔌 Function

The spacer washer sets and maintains the correct clearance and alignment between a mounting support and its attachment point in the inlet and exhaust system. It also spreads clamping load at the fastener to keep the joint stable under engine vibration and thermal movement.

⚠️ Common Signs of Failure

• Visible flattening, distortion or wear from vibration and clamping load
• Corrosion, scaling or heat discolouration from proximity to exhaust components
• Repeated loosening of the associated fasteners or a support that will not stay torqued
• Misalignment or stress cracking of the bracket or component it supports
• Rattling or knocking noises from the inlet or exhaust mounting area

🛠️ Service Notes

• A spacer washer sets a dimension as well as carrying load — keep or measure the original and refit the same thickness unless the workshop manual for your engine tells you to select a different one
• Refit spacers in the same order and the same positions they came from, and keep them with their own assembly while it is apart
• Check both faces for wear, dishing, burrs and fretting marks, and fit a new washer if the faces are no longer flat and parallel
• Make sure the seating faces are clean before assembly; grit or old sealant under a spacer changes the very clearance it is there to set
• Where the spacer sets an endfloat or a clearance, measure that clearance after assembly against the manual figure rather than assuming it
