Help with 220B pump removal.

#1

Post by MitchellC »

First off, this is a 220B right? The manufacture date is 7-38. I’ve got it nearly completely disassembled. The only thing I have left to do is remove the pump, but it’s rusted and seized up. I’ve tried to unscrew it with my leatherman pliers, but it won’t budge. Any tips on how to get it out? Also, I’m having trouble getting the eccentric block out. It’s stuck in. How do you remove it from the tip cleaner?

You're trying to remove the pump cap? Or pump air stem? Careful with heat in this area as things are soft soldered together.

The pump cap. The air stem is unscrewing fine. It’s the old screw on pump cap that I can’t get off.

Try wrapping some leather around the cap and using a good gripping set of pliers to remove it... Again the pump tube is soft soldered in so don't over torque it... Some light taps might help break it free also... The steel has probably rusted and jammed itself against the brass pump tube threads... You'll get it 👍

Try PB Blaster and let it soak overnight. Sometimes patience is the best worker. You don't wont to damage the cap or the fount threads if you can help it. And yes, it looks like a 228B. I'm not sure how long you have enjoyed this hobby. When I first started I destroyed a couple of lanterns.

My trick is apply penetrant to the offending object, then wrap it with a stout piece of leather and put a stout hose clamp around the leather and tighten as much as possible making sure that the leather is not too long, then take an 8 ounce hammer and rap the hose clamp a few times and then apply more penetrant to it, let it sit overnight and rap it again the next day. Repeat until successful. No plier marks.

Rapping it with a wooden handle, screwdriver, penetrating oil helps too. Usually heat applied helps immensely.

Yea, looking at your second photo, it is rusted on. Put on some PB Blaster and let it soak. Every time you walk by, give it another shot. Wrap it in leather or a thick rag and some channel locks should get it off. If it does not to pop off, it will need more PB and another day of soaking. It will come off.

Heat. If have a bit of solder, put a tiny chunk up against pump tube so you can if it starts to melt. Then leather and some gripping tool. It will come.

Why remove the eccentric?

The eccentric block is pretty worn and doesn’t move up and down very well. It still functions, but it almost gets stuck in a couple places as I turn the tip cleaner stem. I was just going to replace it while I have the lantern disassembled. I got the pump cap off though. All it took was a little PB Blaster.

Just back the tip cleaner off a ways and the eccentric will lift out. They often get burred up and don't always lift out smoothly but take a bit of effort. I clean em up with a file

Pull your fuel/air tube from the valve. The early B models had an eccentric that is removed from the bottom, not the top. I'm not sure when they changed this.

I’m not sure the exact timeframe of the long eccentric block but I’m pretty sure that isn’t one.

The long blocks are easy to spot when you have a couple of examples to review!

This is an example of the early one. LEB

I've personally never seen a long eccentric past 1931. They were not used long.

After looking at the eccentric block closely, I think it’s not coming out because it’s mushroomed a little bit where the tip cleaner stem pushes it up. After soaking it in vinegar and spraying it with carb cleaner though, it’s working just fine. No more sticking.

Sounds like things are working in your favor MitchellC.

Looking for 10/59 lantern or fount for rebuilder.
Prefer a 228E, but not that set on it.
