This might be too basic, but it took me a while to remember in the shop yesterday.
The Swiss grease gun is really nice actually- the top has a filler valve, air bleeder valve, and the ability to clean out the ball bearing valve. In my case, all of those were full of ancient grease and I'm working in a cold shop, so they weren't budging.
Pull the plunger out all the way to compress the spring and hook it on the little "keyhole" in the screwtop. Unscrew the assembly, dig out the old hard grease and refill with some new grease.
Remove the nut on the ball bearing valve and check for debris or waxy build-up and clean it out.
Remove the greasing tube and if necessary push a wire into it to break the old grease loose.
Open the top airbleeder screw.
Screw the plunger assembly back on, but keep the spring compressed.
Release the plunger from the keyhole and it will force the air out of the open bleeder valve. Wait until a little clean grease comes out of the air bleeder valve.
Start pumping until the old grease is out of the there.
The filler valve works if you're pumping grease into the gun from a 50 gal drum... not me.
If you like diagrams, these Abnox Wanner ones are very similar... probably the same parts.

Re: Grease gun rebuild!?
Good to know. I tried to use mine but the fitting wouldn't go on the driveshaft zerks. My normal US grease gun worked fine.
I have no idea whether my u-joints are OEM or aftermarket. Or maybe like your's there's just hardened grease in the fitting preventing it from flexing to fit on the zerks.

Re: Grease gun rebuild!?
I had the opposite problem- my US one oozed grease all over and this one fit snugly.

Well, that's consistent then with my u-joints being aftermarket with larger zerks!McCall Pinz wrote:I had the opposite problem- my US one oozed grease all over and this one fit snugly.
