Silca Pump Head Replacement Part

I have an older Silca pump (I think it is the 24.4) with a chuck/head that uses three parts (2 plastic and one rbber) that can switch from presta to schraeder. It is one of the cheaper silca floor pumps they made back in the 80's. The rubber part is worn out and no longer seals.

Anyone have an idea where I can get this part? The rubber parts that I see listed for the 30.0 and 24.0 pump heads don't look the same.

The only thing I've found is a vintage replacement for the head on ebay for $56+shipping.

The pump was called the Silca Pist Track Pump.

This link has a photo of the pimp and chuck

Thanks

An alternative strategy to refurb a vintage pump head that you suggested wasn't high end to begin with is...simply buy a different head.
I am in fact replacing the smarthead on my Topeak with a 'twinhead' made by Topeak. Attachment hose OD tends to be similar pump to pump.
They sell the combo twinhead on ebay that services both presta and Schrader valves. What I like about the twinhead versus the smarthead is...I believe the smarthead to be a bit more of a compromise by trying to fit different valve stem diameters in one head. The twinhead is two perpendicular dedicated orfices which I believe to be a better design. The smarthead and twinhead made by topeak are both rebuildable. Topeak makes the popular Joe Blow Pro..what I have and has great ergos for pumping high pressure unlike other pumps.
Good luck.

I may end up having to replace the whole chuck if I can't find the part. Silca brass chucks are around $20 but I have found the Topeak Brass Superchuck for about $11 shipped and it looks like it would do the job.

That said if I can find the replacement part it is likely only a few dollars and the pump has worked well for 30 years and I like the look of the brass chuck.

Thanks.

Have you tried Colorado Cyclist? I have an old track pump and have bought parts from them in the past.

Thanks, I've been to dozens of cycling websites and they all carry the same two rubber parts. Neither part looks similar to the one in my pump.

Maybe someone knows if the newer Silca 323.1 Rubber Washer For Dual Head would work the older 24.4 chuck?

Feeling a little sheepish, turns out the part that has been in my pump for the last 20+ years was the wrong part from a different manufacturer (SKS) hence my confusion. A local shop that carries lots of parts was able to it figure out and replace it.
