Hi, I'm wondering if anyone has an idea of model of this , I want to replace the seals or rebuild as needed but the only thing I found was a 'W' and a 'D' stamped in the metal but they have separation as if whatever was there was wore off.
That design is an import sold under many names. The seals are probably O-rings. The only way to determine what is needed is to disassemble and measure what is there. There is a lot of information here about what you need. The pictures have disappeared thanks to Photobucket. https://www.garagejournal.com/forum/showthread.php?t=197787
