Fixing a Sticky Auto Valve on a PFP-8 Floor Pump - Intro
The PFP-8 Floor Pump from Park Tools is a nice looking bit of kit, and it works beautifully. However, mine has developed a bit of a problem, in that the automatic "head" does not select between the larger schrauder hole and the smaller presta hole.
For example when trying to pump up a presta tube, the air will come out through the larger hole. Wasting your time and energy, and making you wish you were out cycling rather than piddling around with a pump in your garage.
Fixing a Sticky Auto Valve on a PFP-8 Floor Pump - What to Do
Not much info on the web for this model of pump. So I emailed Park Tools in the USA. Got a response straight away, they also offered to post out a replacment head free of charge. How often does that happen? The instructions for fixing the valve / head assessmbly are here. But read on below if you would like to see how to fix just the head.
1 - You can bash out the metal pin that holds the lever in place.
2 - Take out the rear cap behind the lever.
Hopefully job done!
