Air Pump Problem?? Help

[usranger74]

I am trying to adjust the air pressure in my shocks.

I am using a pump I am told is a "zero loss" pump.

It is a "Progressive Suspension"

I am trying to put 25#s in each shock.

When I disconnect the nipple from the shock nipple, the pump cage drops to 20#. that is, I am losing 5#s when I disconnect.

Am I doing something wrong or is the pump not working right?

Do you hear air escaping as you un-thread the pump from the shock?

You shouldn't be losing 5 pounds of air when you disconnect the fitting. I have no idea why this is happening. I don't lose any air when I disconnect mine. Try putting 30 pounds in and see if it drops to 25.

On my Progressive pump, I screw the fitting on only until the gauge reads what is in the shock, then pump it up to what I want, then quickly turn the fitting to take it off. This way I don't lose any pressure, but If I turn it another time or two after the gauge starts reading the shock pressure, when I remove it, I'll lose about 5 lbs of air.

Dang Cliff, you are the man!

I think I do. Hearing is not the best.

Then I would think something may be not right with the fitting on the pump. Mine makes no air loss noise, nor to my memory does the gauge change till I push the reset button. Could be a bit of dirt or something in there. You could try blowing it out with a bit of compressed air, it might just help.

I tried this and it kinda worked. I did not lose as much air. However, I am not sure that I have the same AP in both shocks and that may be a safety issue. And, if I use the pump to ck the AP, I lose more air.

This pump only goes up to 30 PSI.

Where would be a good place to look for a new pump and any recommendations of a brand.

I bought mine at a HD dealer, $53 bucks with tax. I'm not a fan of anything with a HD tag on it, but it is pretty nice quality, I have to admit.

I bought a Progressive Pump off e-bay, think it was $45 and $5 shipping

Be careful buying one off eBay. Someone is selling them with a gauge reading 0-300psi. It is extremely difficult to accurately fill the shocks with such a large range. You want one that reads 0-60 psi.

Scott - I hit the road Wed for MV. I am going to find one here in the Omaha area. I will ck the HD and Honda/Kawa dealerships in town.

I went to the local HD shop and bought a new zero loss pump. It works. Problem solved. Running 30# per shock.

[desertdog]

The one I bought is 0-60, but I was careful and confirmed that it was a Progressive Pump and that the reading shown on the picture is what I would be getting.

My pump goes to 300 psi. I can regulate it to ABOUT 30 to 40 psi without too much problem.
If you need exact air pressure, then yes, 0-60 is recommended. I have a 0-300 with 50# major and 4 marks in between. It is a FOX Shock pump for bicycles. And as you can see, it will work and has worked just fine. I got it at a bicycle store for $43 cdn.

[Bull Durham]

$43 dollars Canadian, what is that, about $115 bucks American, as bad as our dollar is?

[Blueraven]

Probably, $50US green back. They way it is going, hopefully soon, $115.... :)

Nooooooo! I want it to go back the way it was!

i got my pump from harley, (ugh yeah i know!) it even has the stoopid logo under the glass, but it was like $35, and it goes to 60lbs, perfect for me cause thats what i use mostly touring with my girl, and in general i lose a few psi when i unscrew it, and you dont have to worry about not having both shocks exact to the lb, its not going to do anything, as long as you dont have large disparity between the two, your good to go,
