Alright so after sifting through the search I can’t find what I’m looking for. On my 242c and my 425nl the pump feels like it’s grinding on something. You may be thinking, well duh Levi, it’s probably the cap or the, hmm, check valve stem seems the most appropriate (correct me if I’m wrong). Well, I checked both of those things on both pumps and I’m still no where. I undid the caps and started pumping, it still was rubbing against something and it was hard to pump. Then I spun around the valve stem things in my fingers and they look straight as an arrow. Any ideas as to what the issue is.

Need a little oil on the air stem or pump shaft?  Is leather ok, or are parts holding the cup beyond the cup, scraping the sides instead of the cup?  Spring may be the culprit.  I oil the pump tube with oil on a pinkie and oil the pump cup real well.  I don't have pure Neatsfoot oil, just the compound so whatever else is in it evaporates off, so a reoil is usually needed.  I've had a couple pump air stems that were bent, so they scrape and make pumping a little harder.  Are pump cups positioned correctly, easy to have one fold back on itself if not inserted right or with sufficient oil.

Sometimes, I've found that if the pump knob is unscrewed too much, it can bind. When the pump knob is tightened, I loosen the knob no more than one turn to pump.
Also, as hikerduane mentioned, I've had a neoprene pump cup fold back on itself as well.

Look in the pump tube for pitting and corrosion. I have had this before, it really chews up pump leather bad. The fix is a tool called a brake cylinder hone, fix it to a drill and run it up and down the hole until it smooths it out.

great idea to use a brake cylinder hone. likely a lot easier than using emerycloth and a stick...like I used when I had this problem

I agree with Will, normally it's a rusty pump tube, Timm mentioned awhile back about using one of these and it works great.

Possible the pump stem is bent as well..

Wonder if OP removed parts to look?  Maybe even some grit or dry cup, rust?

i always put some oil on the air stem before inserting it in the pump tube for installation so everything is lubed . submerge the pump leather , maybe flare it out , re submerge then drag the dripping leather over the air stem a few times before putting it all back together . this is the only metal on metal surface that may feel like its grinding ???

Alright. So there was some debris in there. It couldn’t rust because it’s brass. Anyway I cleaned it out with some carb cleaner and oiled everything up. It’s better, but it’s still rubbing on something. I assume it’s the air stem. I did what I know best, and put it in the vise with some aluminum blocks to straighten it out the best I can. The pump cup is perfectly straight, the parts holding the cup on are not rubbing the sides.

I've seen a lot of pump air stems that were bent. Just the tiniest bend and they'll bind. No idea how they get bent. I have a large piece of steel plate on my bench that I use to straighten them back out.

Simple test:  remove the air stem and  try the pump  does it still grind?  if not look closer at the air stem...

Hey Levi! I'm fairly sure I really don't need to tell you, but make sure you're pushing the pump straight in.

Haha, yeah that would probably make an issue. I just put a silkie on and I’m really satisfied with the result. C7A91D4E-E169-4C56-B92E-87EA9680808E.jpeg
