Question about Blackburn Mountain Air Mountain Bike Pump 4 Bicycle

1 Answer

How do I use a Blackburn Mountain air pump?

Hi, when I am inflating a tyre with the pump, what position should the "thumb guard (is that what it is?) be in? Should it be in the stowed position or the extended position to lock onto the valve stem?

Thanks in anticipation.

Dear Doug, to lock a hand pump onto the valve stem: 1.depending on valve type-loosen the valve lock for presta, twist off valve cap for schrader. 2.unlock the pumping handle from the pump so that you can actually "pump" the pump... 3. put the pump head on the valve of the tire, then pull up on the thumb tightening lever. This should squeeze toghether the internal rubber gasket of the pump, and lock on to your valve. 4. Begin pumping. 5. when desired pressure has been reached, push down on the thumb lever to unlock the pump. Remove it. Good Luck Fellow bicyclist!

The pressure gauge on my Topeak Joe Blow Ace floor pump is not working. The pump works fine. How do i take the pump apart and what should I be trying to do to repair?


http://www.ehow.com/how_4779541_inflate-bicycle-tire-presta-valve.html

  1. Rotate the wheel so the valve is resting just above the floor. Remove the valve cap.

  2. Unscrew the locking nut on the valve stem. Quickly press down the stem to loosen the seal. You should hear air escaping when the stem is pushed in--if you do not, loosen the nut and try again.
  3. Press the pump head onto the valve and flip the locking lever to make a seal. You'll hear air escape, but it should stop after you've locked the lever. If air continues to leak out, remove the pump head and reattach it.
  4. Make two pump strokes and listen for air moving into the tire. If the pump handle becomes hard to press down after only a few strokes, or if the pressure gauge elevates extremely quickly, remove the pump head and repeat Step 3.
  5. Inflate the tire to its recommended pressure. Remove the head by unlocking its lever and quickly pulling it off the valve stem. Secure the valve's locking nut and cap.

How do I pump a presta valve with the Blackburn Mountain Air Bike Pump 4 Bicycle


They should be designed to fit both styles of valve, but you need to reverse the seal.
you should be able to unscrew the end, remove the sealing rubber and a plastic fitting that pushes on the valve, replace them the opposite way around ,and they will fit the presta.

Hi, I am having great problems getting the bead of the tyre onto the bead grove on the rim. The majority of the tyre goes on ok but a small section on each side won't go on which causes the tyre not to be...


Using a technique for setting the bead on tubeless tires, i have had a little success, but some wheels are a real pain to set beads on. Anyway, the technique is to get the tube into the tire (which is ready to be seated) and inflate it just a little bit. Don't screw the collar nut onto the valve stem but leave it off for now. Now pinch together the beads of the tire and get them to sink under the tube and into the groove that runs in the middle of the rim. When the beads are down in there, then pump away and seriously go after it; the faster you can get air in there the better. Over inflate, but not more than you feel comfortable with: i have gone as far as 20psi over recommended pressure. The last ditch effort, if all else fails, is rolling the bead into place manually with your thumbs and some elbow grease.
Regards,
matt

Not working


When you remove the tires while changing inner tubes, do you run your fingers through the inside of the tires to check for thorns, wire, nails or other debris before replacing the tubes? Also, check to make sure your rim strips are adequately covering the spoke nipple holes in the rim. Sometimes just a little bit of a hole left unprotected can damage a tube. Lastly, sometimes you will just get bad tubes. It happens.

How do you inflate a Bicycle tire with the small portable pump? the air is coming from the needle to inflate balls and not from the nozzle. It is a Schwinn small portable bicycle pump.


Usually, the needle used to inflate balls is an attachment to the pump. Is there a lever near the fitting the needle comes out of? Moving the lever 90 degrees from its current position should allow you to pull the needle attachment out. The hole the needle came out of is where the valve stem from your tire goes to pump the tire up. Jam the stem in the hole, crank the lever back to lock it in and pump away. Unlock the lever to release the stem when the tire's inflated and you're golden.

I need to remove the rear sprocket to change a broken spoke


A tool that is like a socket goes in the center of the gears. And keeps the sprocket from spinning
And a special wrench slides over the out side gears grips gears.

Then centrifugally forced the sprocket will unscrew clockwise.
You sort of need those tools.
Or if you are good with tools. One can be made.

I'm not sure if that is what you want to do.

But yes, the sprocket is screwed on like a nut.

Hope this helps
