Vic787 Posted May 16, 2022 Report Share Posted May 16, 2022 Having replaced the water pump due to bearing failure, I wondered why the replacement did not have a grease nipple only a tiny hole in the casing of the bearing housing. I thought this was an oiling point but when fitted was underneath and then though is it a drain hole. Question is are the bearings now sealed? Quote Link to post Share on other sites
Andy Moltu Posted May 16, 2022 Report Share Posted May 16, 2022 The short answer is yes, most are sealed for life. The hole may well be a "tell-tale" so you can see more easily if the pump is starting to leak. Quote Link to post Share on other sites
Vic787 Posted May 16, 2022 Author Report Share Posted May 16, 2022 Thanks Andy, like most things sealed for life, keep fingers crossed it’s a long life. Quote Link to post Share on other sites
ianc Posted May 17, 2022 Report Share Posted May 17, 2022 Since the pump just spins on its axis, loading is constant and the grease cannot escape easily, so its life should be long. In fact, one could argue that over-enthusiastic greasing of water pump and of rear hub bearings can create problems by provoking leakage. It's suspension parts where I don't believe in sealed for life - these need regular greasing in order to expel dirt and keep the parts lubricated. Ian Cornish Quote Link to post Share on other sites
