Is ther an explination why it is so difficult to remove a shower cartridge. Remove handle cover plate and horseshoe pin
Grab the valve stem and pull outward seems to hit a "stop" again and again same thing
Why is a puller needed ? I would think that removeng the small horse shoe cartridge pin would suffice Why so difficuly ??

That usually happens when the outer sleeves are binding up on the hot and cold side ports.

Moen Engineering Department cannot work miracles. When rubber is tightly compressed against brass for years, submerged in water with minerals and chlorine, they will stick together. Faucets have to be manufactured to a price point, which means that the quality of the brass and rubber might not be as high as it would be if cost wasn't an issue.

Short answer is that that "something", usually the rubber seals, "roll" up and seize when you pull it out. The last two I worked on it was so jammed that I had to replace the valve body in the wall. When they come out properly, it IS easy, but when it goes bad, it can get really bad.

They think it is the best design they have ever engineered, and WE do not know how to do it properly. When they do it in their labs the stems remove perfectly.

hj, you nailed it. When they're good, they're very good. And when they're bad, they're very bad. (Alice in Wonderland?)
