b61fred Posted April 22, 2009 Share Posted April 22, 2009 Hey guys, I was chasing down that thump noise that was heard through the air cleaner, adjusted the valves and all is well in that department, BUT.... I found this antifreeze puddle under the truck. I didn't think much about it because I figured it was loose hose, or the overflow from the radiator. I found it to be leaking from the weep hole on the pump. so.. I wanted to take it to the truck show at Spring mill this weekend, so I need a water pump NOW... I am going to find out if there is one anywhere that I can get.. If you guys can help I would be very thankfull....Fred Quote 15 gears...no waiting!

KAVIKA Posted April 22, 2009 Share Posted April 22, 2009 I BOUGHT MY WATER PUMP FROM MY LOCAL TRUCK PARTS STORE IT WAS NOT THAT EXPENCIVE BUT THE CLERINCE BETWEN PUMP AND RAD IS VERY CLOSE I ENDED UP HAVEING TO REMOVE THE RAD TO GET TO SOME VERY TIGHT BOLTS. IF THE OLD ONE IS THUMPING I WOULDNT START IT AGEN IF THE BRING SEZES UP IT MAY PUT THE FAN INTO THE RAD. Quote Link to comment Share on other sites More sharing options...

b61fred Posted April 25, 2009 Author Share Posted April 25, 2009 Hi, Here is the update on the waterpump, I found several places that could get one, I contacted two mack dealers, one was $179.00 and the other was $195. I contacted a few NAPA stores and found one for $65.00. It had a picture in the book of three mack pumps, The only difference was the length of the shaft, this was called the short shaft. I was worried about it after what Mike Harbison posted but It was allready ordered at that point. The pump came in Friday afternoon and I put it on that evening, fit perfectly, It was made by cardone and came from Philly Pa. It is a all new casting, and I highly recommend it, I removed one off of the b75 parts truck and it was about 1/2 inch longer. As for rebuilding the old pump, I pressed apart the old pump and found the bearings were standard off the shelf bearings, the seal is something else, I don't know where a person could purchase this seal but the waterpump is defentantly rebuildable. I am going to try and find a seal and bearings and have a spare ready to go for me or someone else in an emergency. All is well now and thanks for everyones input! Fred Quote 15 gears...no waiting!

rick harper Posted May 6, 2009 Share Posted May 6, 2009 You can send in your old pump to the Mack Reman Center and they can rebuild it. You have to go thru a Mack Dealer. The part number should be 316GC184NX. Quote Link to comment Share on other sites More sharing options...
