It appears at multiple assembly points including the PT6LT pump components, PT6Y pump end, PT6YT pump end, and associated transport and wheel kit hardware, making it a frequently needed item during pump disassembly, servicing, or hardware replacement.\u003c\/p\u003e\n\n\u003cp\u003eThe \"B21\" designation identifies this as a metric series washer sized to a 21mm bore, and \"MS\" denotes mild steel construction. Washers at these assembly locations distribute load across fastener connections on pump housings, impeller assemblies, and frame-mounted hardware. During routine maintenance, reassembly of pump end components, or wheel and transport kit installation, worn or damaged washers at these joints should be replaced to preserve proper clamping force and prevent hardware loosening under vibration.\u003c\/p\u003e\n\n\u003cp\u003eCompatible models include:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eGPS 8500\u003c\/li\u003e\n\u003cli\u003eGPS 9700 \/ GPS9700\u003c\/li\u003e\n\u003cli\u003eGS 12Ai\u003c\/li\u003e\n\u003cli\u003eGS 8.5V\u003c\/li\u003e\n\u003cli\u003eGS 9.7V\u003c\/li\u003e\n\u003cli\u003ePT 6LS \/ PT 6LS(I)\u003c\/li\u003e\n\u003cli\u003ePT6LT \/ PT6LT(I)\u003c\/li\u003e\n\u003cli\u003ePT6Y \/ PT6Y EPA T4\u003c\/li\u003e\n\u003cli\u003ePT6Y-AU \/ PT6Y-SA\u003c\/li\u003e\n\u003cli\u003ePT6YT \/ PT6YT-IN\u003c\/li\u003e\n\u003cli\u003ePTK 6\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eGenuine Wacker Neuson OEM part, sold by an authorized dealer.\u003c\/p\u003e","brand":"Wacker Neuson","offers":[{"title":"Default Title","offer_id":43396620615728,"sku":"WACKER-5000077873","price":22.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6574\/7248\/files\/5000077873.jpg?v=1784013748","url":"https:\/\/cce-industries.com\/products\/wacker-neuson-flat-washer-b21-ms-5000077873-for-trash-pumps","provider":"CCE Industries","version":"1.0","type":"link"}
