984225 Inner Ring | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta inner ring weighing 0.077 kg and listed for 20 applications across DPH, D and DPI drives. It is the hardened race the needle roller bushing 984224 runs on, and that bushing carries exactly the same application listing, so the two belong to the same bearing position.
