Isn't pulling air in properly when I pull, so not much air being pushed out. Has anyone here taken one apart? I can unscrew the barrel to get it into two halves but I want to dismantle the handle end where the business end resides.
I think that's what I had, or similar. Pics here show how it came apart after possibly its first use. It became very difficult to extend, then the shafts came apart. I then took it to bits to have a look. As per pics.

I think part of the issue was that there's a gap between the body & the handle where grit gets into (it was mounted on downtube bottlecage) & then when I used it it just scored the shaft & created lots of friction making it very difficult to extend.
Or maybe the air intake got blocked up.
I'm not sure if the pics show the bit you were after.
Might be a lube issue. A dry shaft can bind. Break it apart and spray some gt85 in if you can't see anything broken
Thanks for the photos pipm1. I need to find some way of removing the black collar. Looks like it needs tiny pin wrench or maybe I can tap it round with a small screwdriver.
I'll try the lube option too joshvegas. Ta.
