Valve stem install

[Tundra]

I got my new valve stems (patchboy). I here you can break your bead and install on the bike. Can I
re-inflate with my Devilbis twin tank compressor? ...OR... will I need some monster commercial compressor to seat the tire to the rim? TIA

My neighbor's little direct drive compressor can put tires back on the bead... anything that's not a bladder pump can
probably do it...

You're a big dude, perhaps you can break the bead with the wheel on the bike and reach up in there
and tighten down that new valve stem, sounds real hard to me... let us know if you try how it goes...

I figured a clamp would break the bead for me the first time I changed a tubeless tire... four clamps only
broke the bead on one side:



Here's the way I do it now (the "Raymond method"...):

Take the core out to deflate.  Take a large "C" clamp and put something underneath one side against the rim like a small 1 by 2 or hard plastic, so you don't scratch or mar the rim.  Put the other side on the tire near the stem, also using something to make the footprint of your clamp a little larger so you don't damage the tire.  Run the clamp down to break the bead.  Trim the rubbber off inside the tire, taking care not to damage the rim, pull the old stem out.  Install the new one with the larger of the two rubber parts inside if my rememberer is working and put the two nuts on and snug up one, then the other.  Take the clamp off and the tire will seal well enough to inflate.  If by chance it does not, wet a rag and wipe around the tire.  Your compressor should work fine.

I just replaced my rear tire last night (for the first time myself) and used the leverage method to break the bead.  I have a little 10gal Sears compressor so I couldn't pump a lot of volume into the tire.  So, I used a trick I have used MANY times on wheel barrow tires.  I put a ratching strap around the tire, in the center of the tire, and tightened it up a little.  This pushed the bead onto the rim just enough to seal off.  I think it took 3 cycles on my poor little compressor to get the tire up to 43 psi.  But, I got it!!!

I have done 2 fronts this way.  It may take more than one clamp on the back as the tire will be stiffer.

Thanks all

I guess you're having trouble with the valve stems that you have?  If not, I would wait till tire changing time.
I needed a ratcheting strap to seat mine and you should not need excessive pressure to seat.I was reading something the other day somewhere that you should not exceed 40 psi to seat your tire-that it can be dangerous to keep putting more pressure in to seat the bead of the tire.They instructed that if you're having trouble seating the bead to back off and re-lubricate bead and rim and along with the strap-try again.

It's always recommended to lubricate the tire bead. For installation as well as seating the bead.

Really you only need to break the bead on one side to replace a valve stem.

BTW... If you have the 90 degree valve stems make sure you either use the all metal nut type or carry spare plastic supports. The centrifugal force can cause the rubber seal on the factory stem to tear at the most inopportune moments (Like Wilkerson Pass Colorado in the switchbacks) Then you end up like this...



A couple of C - Clamps and a small air compressor will break the bead and allow access to replace the valve stem (Although it is very hard to find a 90 degree stem after the streets have rolled up in BFE, and a straight stem is a PITA to get air to) It will get you back on the road in a pinch.

Thanks Gunslinger, I've been there,  I don't have any pictures to prove it. My mistake was putting OEM valve stems back in Now I just want to replace them cause I know better. That was NOT a pleasant experience for me. Don't care to repeat it.

I've done it that way before, but it is dangerous as hell.   I did it in the desert.  Battery operated compressor, oh yeah, spare was flat also.

Like most have said, a couple of big C clamps should be able to break bead after deflated.  I was on an iron butt ride on a GL 1200 Goldwing about 8 years ago and had a stem split on a rear tire doing 70 miles per hour near Tifton GA on the interstate.  As you can imagine that was fun trying to get control and get the bike to the shoulder of the road, but did it somehow.  I was with 2 buddies and it was their first Iron Butt ride.  Was thinking of throwing in the towel and calling a tow truck but did not want to disappoint my Buds so rode bitch down to Lowe's and bought 2 C-clamps and a new stem.  We put duct tape around the old stem and put enough air in the tire (had battery operated small compressor with me)to limp to the next exit (exit was within sight of the incident about 3/4 mile).  Got the bike to a 7-11 with an air pump, put the bike on the center stand (thank God the old GL1200's had one), used the C-clamps to break the bead, took out old stem, pushed in new stem from underneath, pumped up the tire and finished the Iron Butt ride in 23 hours and 45 minutes.  Whew, that was a long sentence and a long night.

Take the valve core out when inflating to seal the bead and you can get the volume in quicker, also.

  I know this is an old thread but it describes my question.
Two weeks ago I removed my rear wheel, took it to a bike shop and had a CT installed. I have didn't think to replace the stock valve stem  . I reassembled the rear and put 200 miles on the tire. Checked the pressure and I was low. Sure enough the valve stem is leaking. I ordered new stems from Patchboy...........My question is can the "C-Clamp" method be used on a CT or should I bring remove the wheel and have the bike shop install the new valve ?

TIA

Do to the width of the ct, I doubt you'll be able to use the C clamp method.  You'll probably need to take it to a shop.

C-Clamp method will work on a CT, I've done it...

It takes a little bigger clamp, but the process is the same.

[Ferris Leets]

Did you check that the schraeder valve was screwed in tight?  I've gotten my wheel back twice with the valve loose enough to leak.

[Tonysax]

  The Patchboy valve stems came today. Thanks for the heads up (Gunslinger) , with the CT I broke the bead with (3)  8" C-Clamps, after removing the core (Ferris- which I replaced day before to rule out) The new Patchboy was a breeze  . Since I had the bike on a jack , I replaced the front one also in 15 minutes. QUESTION..... Has anyone ran into trouble with these valves? I'm going to carry a spare, it's definately do-able with C-Clamps in a parking lot.

[Gunslinger]

it's definately do-able with C-Clamps in a parking lot.

My pics were taken in front of our rental cabin in Colorado shortly before Inzane, lol

An actual parking lot would have been nice. If a person had the c-clamps, a spare valve stem and a compressor I think it could be done on the side of the road.

You guys remember the the hard black plastic VCR tape boxes ? I took one and carry 2 spare valve stems, package of tire plugs and plug tools. Plus a digital tire gauge.
The tape box closes into a great parts container that lays on the saddlebag floor less than an inch tall. Strong enough not to crush from things loaded on top.
