Guest Stephenmilner Posted April 12, 2015 Share Posted April 12, 2015 Hi Guysmy waterpump in my 28 buick has water coming out of the grease nipple on the pump housingI use my grease gun to fill it and it lasts about 50 k's then will drip again.does this mean the seal needs replacing on the shaft. Should I put a kit in it to replace the lot and if so does anyone have a diagram of the pump and what I will find when work starts. Bobs have a kit now in their catalogue. Thanks for all the other advice you have given me in my other posts and they all have worked.cheersSteve Link to comment Share on other sites More sharing options...
Mark Shaw Posted April 12, 2015 Share Posted April 12, 2015 Steve, The ball stop in the grease fitting is worn or damaged. The drip from the grease nipple can be eliminated by just replacing it. Link to comment Share on other sites More sharing options...
Guest Stephenmilner Posted April 12, 2015 Share Posted April 12, 2015 Thankyou MarkShould there be water under the grease nipple or is there a seal between the shaft and water pump?cheersSteve Link to comment Share on other sites More sharing options...
Dave_B Posted April 14, 2015 Share Posted April 14, 2015 Steve, There is only one seal and it is on the end closest to the distributor under the packing nut. the inside end of the bearing is not sealed from the water. There are some water proof greases that can be used in this application, but usually people just follow the manufacturers lubrication schedule, every 500 miles.Dave Link to comment Share on other sites More sharing options...
Guest Stephenmilner Posted April 14, 2015 Share Posted April 14, 2015 Thankyou DaveI thought as much, so am using a marine high temp grease in the water pump. Do you know what thread is on the grease nipple as I want to replace it and auto shops can't work it out.Thanks everyoneCheersSteve Link to comment Share on other sites More sharing options...
Mark Shaw Posted April 14, 2015 Share Posted April 14, 2015 Steve, The grease fitting should be the same as the rest of your car. You should be able to swap it with one from your chassis. Link to comment Share on other sites More sharing options...
