Sks rennkompressor pump issues

Posted on
  • I’ve had an sks track pump for ages- it used to be ok at doing track tubs at 150psi+ but it seems to be getting insanely hard to use- I can hardly pump it above 15psi on my mtb. I’m 6foot4 former sprinter so I assume it’s not me that’s the issue!

    In contrast I used one at a helpful local shop the other day and it was so easy to push down I nearly fell over! My cheap bontrager track pump I keep in Spain was equally easy- did 85psi on road bike and 30 psi on in laws town bike no issue.

    Has anyone had similar or done a service on their pump? Sks sell the bits but don’t offer much advice on maintaining. It’s killing me at the moment!

  • Used them as shop floor pumps, they used to get a lot of use and a fair amount of abuse.

    Do this:

    Also clean and lightly lube the seal (silicon spray is good but chain lube does the trick) at the bottom of the plunger.

  • Thanks I think that’s what I need, will try tomorrow

  • Would you unscrew the plastic cover to get at the seal to lube it or just spray some on the shaft and pump it a few times?

  • Unscrew the top, there’s a rubber bung/plunger at the bottom

  • SKS were great when mine developed a fault, no questions asked they posted me new parts and it was well out of warranty - worth asking them if cleaning it doesn't fix it
