... from what I found, watch out for silicone lube.
North came out with a little white tube of the stuff, apparently silicon lube, that's what I was told it was and it came with the new pumps of the day, so surely its gunna work. Nope. Found out it was complete rubbish. Made things worse. Dumb arze here thought of being pro-active and give the pump a once over before the pump showed signs of wear and tear and f me the pump bound up and jammed 5 minutes later. W T F!! Bloody useless. Did they even test it???
I tried a bunch of stuff to fix it and the only stuff that finally worked was silicon grease. Same stuff you can use on camera housing seals. I gave the internals a good clean wiping all the other crap off then applied it to everything. Instantly worked well but I figured the true test will be the test of time. Worked great there too,,,,, up until some azzhole stole it so I'd probably still have it.
WD40, Inox or any of those oil lube type of stuff lasts for one kites worth maybe then seems to attack the seals and makes things greasy black and messy and then failed anyway. Tried graphite powder too,,,,, geezus that was a stupid idea!
Anyway, in my opinion the silicon grease works great.
cheers,

ps living in hot humid tropics with big kites so I do a lot of pumping and I found don't pump up too fast, slow down. Heating the shaft buggers the seals quick smart.
Big voids in silicone spray quality Robbie
Hence the wurth brand
Saying that a tin is possibly close to a new pump
Anything static or greasy here doesn't work due to fine sand
North kite pumps suck
... The old North pumps suck for sure but so did they all back then,,,,,, these new ones are great!
Silicon grease I use is 'Rocol' brand which is apparently a good quality, same same quality as Wurth I'm lead to believe. You can get it from Blackwoods.
Anyway, for old pumps, what I found is the grease 'fills gaps' so if you have a top seal ie the seal in the lid, that is well worn and leaks air,,,,, the grease fills the gaps in the seal and the pump works like brand new with its original delivered volume. Silicon spray or silicon lube didn't fix this for me.
The grease doesn't make that much difference in the new pumps with exponentially better seals so I only use a little bit,,,, old pumps heaps.
