The most common cause is a weeping mechanical seal letting water track back along the shaft into the front bearing. Fitting new bearings without replacing the mechanical seal usually means doing the job again. Check that the shaft slinger is present and intact while the motor is apart.\u003c\/p\u003e\n\u003ch3\u003eFitting Notes\u003c\/h3\u003e\n\u003cp\u003eBearing replacement needs a puller and a press or a correctly sized drift. Never drive a bearing on by hitting the outer race, which brinells the tracks and guarantees early failure. Always replace both bearings, never one. This is workshop work for someone equipped to do it, and electrical reconnection must be carried out by a licensed electrician.\u003c\/p\u003e\n\u003ch3\u003eOther Pump Motor Bearing Sizes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/pump-motor-bearing-6201-2rs\"\u003e6201 - ID 12mm, OD 32mm, W 10mm\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/pump-motor-bearing-6202-2rs\"\u003e6202 - ID 15mm, OD 35mm, W 11mm\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/pump-motor-bearing-6203-2rs\"\u003e6203 - ID 17mm, OD 40mm, W 12mm\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/pump-motor-bearing-6205-2rs\"\u003e6205 - ID 25mm, OD 52mm, W 15mm\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/pump-motor-bearing-6302-2rs\"\u003e6302 - ID 15mm, OD 42mm, W 13mm\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/pump-motor-bearing-6303-2rs\"\u003e6303 - ID 17mm, OD 47mm, W 14mm\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/pump-motor-bearing-6304-2rs\"\u003e6304 - ID 20mm, OD 52mm, W 15mm\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eWhat size is a 6204 bearing?\u003c\/strong\u003e\u003cbr\u003e20mm inside diameter, 47mm outside diameter and 14mm wide.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the Onga 703612 a 6204?\u003c\/strong\u003e\u003cbr\u003eYes.
