This Lezyne pump didn't last 4 months before I had to attempt this fix. Too bad I wasn't even able to get the barrel off the base, pretty much factory tightened. I called them again and they told me to go into a local bike shop to have them fix it. Really?! Why don't you fix your faulty product yourself! This will be a "good when it once worked" product. Horrible and unreliable product Lezyne, never again.

My question is why does a $70 pump need to be repaired so often? I have one and am cleaning it and re-greasing it every 3 months. Maybe I need to replace the gaskets. My 20 year old $20 pump has never needed any repair. I replaced it because it would not stay on smooth tube necks and the Lezyne has the screw on.

Tip for removing the barrel - grab a tube and wrap it around the barrel for extra grip. Stick with it for a minute or two and it'll start turning.

I work at Lezyne, and removing the barrel from the base is not the way to do this. It makes the repair much harder than it has to be, and we do not recommend using the lower bumper as the replacement. Switch the upper bumper visible in step 5 with the piston seal, and ignore steps 1, 2, and 6. Step 7 has nothing to do with the problem being addressed here.

If you are re-greasing it every 3 months, you are using too much grease. The O-ring should just be shiny and no clumps of grease should be visible. If switching the O-rings and wiping off any excess grease doesn't remedy the problem, please contact our customer service department, and we will send you a replacement O-ring. Lezyne stands behind all of our products, and we will work to find a solution for you.

If you are using a presta valve chuck, the leaking problem is most likely the small o-ring just inside the threaded part of the chuck. It is the primary seal at the presta valve. It wears out after threading and un-threading the chuck dozens of times because the male threads of the presta valve are cutting into the rubber o-ring. The best solution is to replace the o-ring, however Lezyne doesn't offer to seel this 15 cent part, instead you can buy a $13 chuck! A quick temporary solution is to remove the o-ring and flip it over and re-install it. This will give a new surface to seal against untill it wears out.
