Silca floor pump: how to use?(6 posts)

Silca floor pump: how to use?Toddly
Oct 1, 2001 10:58 PM
I bought the highly reviewed Silca floor pump and cannot get the damm thing to work. The head will not stay on the presta head... I've tried twisting it on; pushing it down as far as it can go; and even holding it on with one hand (which works but somehow I don't think that's the recommended method). Any suggestions would be appreciated.

Thanks.

I'm not sure which valve chuck you have. They make three types but usually sell them with either a dedicated presta chuck or a presta/schraeder combination. Sounds like you might have the latter. If you only use presta tubes, I'd go back to the seller and get the dedicated presta chuck. They cost about $5-6 but may swap it for free.

One thing to try in either case is to tighten up the chuck's screw on fitting which will compress the rubber washer inside of the chuck, thereby making a tighter fit around the valve stem.

If you have the so-called shraeder/presta pump head, try unscrewing the top, removing the washer and turning it around. It may be on the shraeder side.
I agree with dzrider but you also have to flip the little plastiHighgear

-c barrel too. It is under the rubber washer. lickbike.com sells a silka valve that has a lever you flip and it really holds well on the presta type valves.

Also, are you securing the valve after you've pushed it down on the stem?

My Silca pump is a few years old, but I assume they are still made the same. There is a wire lever/loop attached at the end of the hose where the chuck attaches. After the chuck is placed down all the way on the valve stem, then this lever/loop must be pushed down and locked into position (against the hose basically) to clamp down. Otherwise, you'll blow the chuck off the stem the minute you start pumping.

PS -- why are things so hard to describe accurately in writing?

Ditch the Silca head and get the Topeak conversion kit. they make a double sided head as well as a universal. I finally got tired of keeping up with the care and feeding of the stock Silca head and have never looked back. This also keeps the uninitiated from trashing the Silca head when they mistakenly try to put it on the wrong type of valve stem. Sure you can go to a good bike shop and buy the exact little part, but that gets old after a while.

Just say NO to Zefal ;-)
