3887170 Shim | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta shim 0.49 mm thick, from the Fuel System group, listed for 6 applications on D series engines. It sits one step below the 0.50 mm shim 3887171 in a five step family, yet its published weight is thirty times higher than that of the thicker shim, so the weight figure cannot be used to choose between them.
