{"product_id":"828383-tab-washer-genuine-volvo-penta","title":"828383 Tab Washer | Genuine Volvo Penta Part","description":"\u003ch2\u003e🔧 Product Description\u003c\/h2\u003e\u003cp\u003eGenuine Volvo Penta lock washer for propeller shaft nuts, listed for 25 mm and 30 mm shafts manufactured before V9338 - week 38 of 1993 - and weighing 0.011 kg. It is the only washer of the three listed that covers two shaft sizes, and it is the one to use on the older shafts: after that date the 25 mm washer is 873475 and the 30 mm is 873488. It supersedes part numbers 19508, 811935, 833916 and 947724, one of which was catalogued earlier simply as a washer and another as a spare part. Nut 828380 also replaces 811935 and 833916, so an old parts list quoting those numbers may need both items.\u003c\/p\u003e\u003ch2\u003e⚙️ Key Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFor 25 mm and 30 mm shafts\u003c\/li\u003e\n\u003cli\u003eFor shafts manufactured before V9338, week 38 of 1993\u003c\/li\u003e\n\u003cli\u003eThe only one of the three lock washers covering two shaft sizes\u003c\/li\u003e\n\u003cli\u003eSupersedes 19508, 811935, 833916 and 947724\u003c\/li\u003e\n\u003cli\u003e0.011 kg\u003c\/li\u003e\n\u003cli\u003eShaft diameter: 25 mm and 30 mm\u003c\/li\u003e\n\u003cli\u003eShaft manufactured: before V9338 (week 38, 1993)\u003c\/li\u003e\n\u003cli\u003eFits: Volvo Penta propeller shafts, 25 mm and 30 mm, manufactured before week 38 of 1993\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003e🔌 Function\u003c\/h2\u003e\u003cp\u003eLocks the propeller shaft nut so it cannot back off under vibration and load reversal.\u003c\/p\u003e\u003ch2\u003e⚠️ Common Signs of Failure\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eShaft nut found slack, or the washer tab broken away\u003c\/li\u003e\n\u003cli\u003ePropeller with detectable movement on its taper\u003c\/li\u003e\n\u003cli\u003eWasher cracked at a fold, or already flattened out\u003c\/li\u003e\n\u003cli\u003eCorrosion between washer and nut face\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003e🛠️ Service Notes\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCheck the shaft's manufacturing date - this washer is for shafts made before week 38 of 1993, and 873475 and 873488 cover 25 mm and 30 mm shafts made after it\u003c\/li\u003e\n\u003cli\u003eSingle use: fit a new washer whenever the shaft nut is disturbed\u003c\/li\u003e\n\u003cli\u003eCheck whether nut 828380 is also needed, since it replaces two of the same old numbers\u003c\/li\u003e\n\u003cli\u003eV9338 means week 38 of 1993; the washer differs between shafts made before and after that date\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003e🔄 Supersession \u0026amp; Cross Reference\u003c\/h2\u003e\u003ch3\u003eOEM Supersession Chain\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e828383 → Supersedes 19508 → Supersedes 811935 → Supersedes 833916 → Supersedes 947724\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eOEM \/ Related Numbers\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e947724 earlier number superseded by this part\u003c\/li\u003e\n\u003cli\u003e19508 earlier number superseded by this part\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003e📦 Condition\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eGenuine Volvo Penta part\u003c\/li\u003e\n\u003cli\u003eBrand new\u003c\/li\u003e\n\u003cli\u003eSupplied in original or equivalent packaging\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Volvo Penta","offers":[{"title":"Default Title","offer_id":53385788490020,"sku":"1952635","price":22.25,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0994\/8115\/7924\/files\/original_8f9a4011-1f6a-4f55-8bef-efffd1084855.jpg?v=1788098398","url":"https:\/\/www.sawleysautoandmarine.com.au\/products\/828383-tab-washer-genuine-volvo-penta","provider":"Sawley's Auto and Marine","version":"1.0","type":"link"}
