Pump Nut kit upgrade
Had issues with pump developing psi, and found the Nylon nut had fractured (see pic). Replaced the leather Gasket, and the Nylon nut using #731 gasket & Nut kit.
Very easy, but worth watching video for tips on the job.
I purchased my pump in the mid 80's and its performed wonderfully the whole time until I started bragging about it on a bike forum. I ordered the washer kit and the leather cup and it's working again.
I also have a Silca CO2 adapter I carry with me on my bike.
This kit with a new leather plunger brought my 40 plus year old pump back to life. The sales team and customer service are very helpful and a pleasure to deal with.
