David_Leech 59 Posted August 13, 2017 Share Posted August 13, 2017 The outter shaft nut on my '28 Standard Six water pump came loose and ruined the shaft packing. I tightened it back up but it still leaks too much. I want to minimize down time by repacking the shaft in one go. I can't seem to find any specs on the packing rope such as size and material composition. Short of removing the packing and measuring the pump, then locating the correct packing, which I want to avoid, does anyone know what size and type to use? I have a local industrial seal supply that has every type of sealing rope ever devised. Really big to really fine rope. Any help would be appreciated Thanks, Dave Link to post Share on other sites
cahartley 609 Posted August 13, 2017 Share Posted August 13, 2017 If the shaft is worn, and it probably is, you won't be able to keep packings in it to save your life....... Link to post Share on other sites
David_Leech 59 Posted August 13, 2017 Author Share Posted August 13, 2017 I'm looking to make it through the rest of the season before I rebuild it properly. I have had the car two weeks and just got it on the road this weekend. Not much drive time left this year before she goes into storage Link to post Share on other sites
robert b 99 Posted August 14, 2017 Share Posted August 14, 2017 The packing is 1/8 square woven and is cut into rings around a 5/8 wooden dowel , the rings are than placed around the pump shaft with the cuts opposite each other . To pack an empty gland you will need 3 to 4 rings and a little grease, do dot over tighten ,only enough to stop leaks. bob Link to post Share on other sites
Spinneyhill 1,430 Posted August 14, 2017 Share Posted August 14, 2017 I think mine is a PTFE square woven or braided "rope". Use a little petrolatum grease without molybdenum disulphide, which will cause the shaft to corrode if the grease dries out (galvanic corrosion). Link to post Share on other sites
David_Leech 59 Posted August 15, 2017 Author Share Posted August 15, 2017 Thanks guys, just what I needed to know. If I was trying to make it through the season, could I get by packing a bit of hardware store plumbing type graphite rope against the existing seal or is this a waste of time? I'm in a parade on Thursday. I likely won't have any issues but could rest assured if there is a possibility of making it better - Dave Link to post Share on other sites
cahartley 609 Posted August 15, 2017 Share Posted August 15, 2017 Graphited woven rope packing has been the gold standard for irrigation pumps since forever. 1 Link to post Share on other sites
Spinneyhill 1,430 Posted August 15, 2017 Share Posted August 15, 2017 If you use graphited rope make sure the grease doesn't dry out. Accelerated galvanic corrosion of the shaft will ensue. Link to post Share on other sites
BlackeysGarage 11 Posted August 18, 2017 Share Posted August 18, 2017 I ditched my water pump and replaced it with a 12v remote water pump, Google Search it and you will find all kinds of different configurations. I'll post pics of my set up shortly, but I mounted near the fire wall recessed into the frame rail. Link to post Share on other sites
Ron Lawson 324 Posted August 18, 2017 Share Posted August 18, 2017 That's a bit hard to do BG as the Standard 6 are 6 volt system Link to post Share on other sites
David_Leech 59 Posted August 19, 2017 Author Share Posted August 19, 2017 I'm keeping it original. It's not about looking for a modern solution, it's enjoying the way it was done 90 years ago. I work at a Mack Trucks dealership. Simple machines like these give me great pleasure. Totally different than what I do day to day. 1 Link to post Share on other sites
