It serves as a direct equivalent to the Westerbeke 24353 glow plug, giving owners a reliable replacement part sourced from Sierra, a name that has supplied engine and drive components to the marine industry for 50 years. Sierra parts are built to meet or exceed the performance of the original equipment they replace, while standing up to the demands of the marine environment.\u003c\/p\u003e\u003cp\u003eThis glow plug features a metal alloy core and top construction with an M14x1.25 thread size, and is sold as a single unit. It is designed to fit a wide range of Westerbeke generator models identified by their BTD, BTDA, BTDB, BTDC, WMD, WTA, BED, BEDA, and BCD model codes, spanning generator sizes from 4.4 to 32.0 kW at 60Hz (and their corresponding 50Hz ratings). Replacing a worn or failed glow plug with the correctly rated Sierra 223-1000 helps restore reliable cold-start performance for the generator's ignition system.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 223-1000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Glow Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 12 Volt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size:\u003c\/strong\u003e M14x1.25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCore Material:\u003c\/strong\u003e Metal Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTop Material Type:\u003c\/strong\u003e Metal Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.06 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282291396\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Equivalent Part Number:\u003c\/strong\u003e 24353\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eWesterbeke generator models: 10.0 BTD(60HZ)\/7.5 BTD(50HZ), 10.0 BTDA(60HZ)\/7.5 BTDA(50HZ), 11.0 BTD(60HZ)\/8.3 BTD(50HZ), 11.0 WMD(60HZ)\/8.3 WMD(50HZ), 12.5 BTD(60HZ)\/9.4 BTD(50HZ), 12.5 BTDA(60HZ)\/9.4 BTDA(50HZ), 12.5 BTDB(60HZ)\/9.4 BTDB(50HZ), 12.5 WMD(60HZ)\/9.4 WMD(50HZ), 15.0 BTD(60HZ)\/12.0 BTD(50HZ), 15.0 BTDA(60HZ)\/12.0 BTDA(50HZ), 15.0 BTDB(60HZ)\/12.0 BTDB(50HZ), 15.0 BTDC(60HZ)\/12.0 BTDC(50HZ), 15.0 WTA(60HZ)\/12.0 WTA(50HZ), 20.0 BED(60HZ)\/16.0 BED(50HZ), 20.0 BEDA(60HZ)\/16.0 BEDA(50HZ), 20.0 WTA(60HZ)\/16.0 WTA(50HZ), 25.0 BED(60HZ)\/20.0 BED(50HZ), 32.0 BED(60HZ)\/25.0 BED(50HZ), 4.4 BCD(60HZ), 4.4 WMD(60HZ)\/3.3 WMD(50HZ), 6.0 BCD(60HZ)\/4.5 BCD(50HZ), 7.7 WMD(60HZ)\/5.8 WMD(50HZ), 8.0 BTD(60HZ)\/6.0 BTD(50HZ), 8.0 BTDA(60HZ)\/6.0 BTDA(50HZ), 8.0 WMD(60HZ)\/6.0 WMD(50HZ)\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e24353\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat voltage is the Sierra 223-1000 glow plug?\u003c\/strong\u003e The Sierra 223-1000 is a 12 volt glow plug designed for Westerbeke marine generators.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Sierra 223-1000 replace a Westerbeke glow plug?\u003c\/strong\u003e Yes, the Sierra 223-1000 is the equivalent replacement for Westerbeke part number 24353.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat thread size does this glow plug use?\u003c\/strong\u003e The Sierra 223-1000 glow plug has an M14x1.25 thread size.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the Sierra 223-1000 glow plug made from?\u003c\/strong\u003e Its core and top are constructed from metal alloy.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 223-1000 glow plug weigh?\u003c\/strong\u003e It weighs 0.06 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich Westerbeke generator models is this glow plug designed for?\u003c\/strong\u003e The Sierra 223-1000 is designed for Westerbeke generator models identified by BTD, BTDA, BTDB, BTDC, WMD, WTA, BED, BEDA, and BCD codes, ranging from 4.4 to 32.0 kW at 60Hz, with corresponding 50Hz ratings.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many glow plugs come in the package?\u003c\/strong\u003e The Sierra 223-1000 is sold as a single glow plug, with a unit count of 1.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 223-1000 an OEM or aftermarket part?\u003c\/strong\u003e It is a Sierra aftermarket part engineered to meet or exceed the performance of the original Westerbeke 24353 glow plug it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 223-1000 glow plug?\u003c\/strong\u003e The UPC for the Sierra 223-1000 glow plug is 808282291396.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 223-1000 compatible with other generator brands?\u003c\/strong\u003e The Sierra 223-1000 is listed as fitting Westerbeke generator models;
