Member Jonathan Kay Posted July 17, 2013 Member Share Posted July 17, 2013 Just tried to do this for the first time. Ancient lever-action grease gun. Grease just squirts out where the gun meets the nipple. Can't find what to do to sort this out in the archives. Beginners' guide, please. Thanks Jonathan Link to comment Share on other sites More sharing options...
Stationary M25 Traveller Posted July 17, 2013 Share Posted July 17, 2013 Sounds like the nozzle on the gun hasn't locked on to the grease nipple ? Should bite on and need a hefty pull to remove it. No good trying until it is locked on. Link to comment Share on other sites More sharing options...
Birkin S3 ZA. Posted July 17, 2013 Share Posted July 17, 2013 Hi Jonathan, If the nipple head is damaged or rusted it will not seal very well. The grease gun head has a seal inside and if damaged it also wont seal, get some one to help you by pushing the head onto the nipple hard and pump at the same time. once it gets a bit of pressure it some times seals, if not change the nipple and grease gun head. If its not been greased for a long time the grease could be hard in the UJ, remove the nipple and poke out old grease with some wire. Chris.

Paul Deslandes Posted July 17, 2013 Share Posted July 17, 2013 some grease guns allow you to adjust the head to suit the nipple size,,,,,, oh dear! Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted July 17, 2013 Author Member Share Posted July 17, 2013 Thanks everybody: that's very helpful. I don't get any locking on at all: just end to end contact. Does that mean there's something wrong with the end of the grease gun, whether the nipple is blocked or not? Jonathan Link to comment Share on other sites More sharing options...
Birkin S3 ZA. Posted July 17, 2013 Share Posted July 17, 2013 That would be right Link to comment Share on other sites More sharing options...
Paul Deslandes Posted July 17, 2013 Share Posted July 17, 2013 can you tighten the end of the grease gun by turning the nozzle? Mine has some flats on the shaft so it can be held whilst the nozzle is tightened or loosened by hand. See here. Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted July 18, 2013 Author Member Share Posted July 18, 2013 End cap on coupler was too tight. Backing it off means that I can now clip onto the nipple, and release by tilting and pulling. I've set it so that it's tight on as feels sensible. Balls in the nipples lift nicely when probed. So I've pumped the grease in until it starts coming out of the end of the coupler. If I then lift the ball I get a backflow of clean grease. But I don't see any grease appearing elsewhere around the assembly... what next?

Paul Deslandes Posted July 18, 2013 Share Posted July 18, 2013 Right ho! Well, if the grease is going into the joint, which it sounds as though it is, then it'll work its way around to where it needs to be as the UJ is flexed. If you keep on pumping in grease, it pushes the seals out which are then unseated and probably don't keep the grit out afterwards. I usually keep pumping until old grease just starts to ooze from the seals without them actually being pushed out. The grease always tends to come out of one place rather than uniformly all round. Bear in mind that, unless the propshaft is severely out of line, the joints aren't flexing much anyway. Link to comment Share on other sites More sharing options...

Grim Reaper Posted July 21, 2013 Share Posted July 21, 2013 You should get clean grease out of all the seals before you could consider the joint correctly regreased. It can be a problem when the new stuff takes the path of least resistance, but without seeing the old stuff out of the joint you cannot be sure the whole of it is getting the benefit of the new stuff.
