Valve Stem Replacement

[Coyote]

I just busted my first tire ever using my new Harbor Freight tire machine and various goodies from Nomar and others. I'm going to put on a set of 90 degree valve stems from BikeEffects.

I know I can butcher out the old valve and my new ones screw together, but I got curious :dribble: about how the standard one got in there and how tire shops remove them. After a long session with Google, I couldn't find anything on how those suckers get into and out of a wheel. Is there some kind of tool or are you supposed to just talk it out there? :blink:

Diagonal cutters, or dikes, for short.

If you do manage to talk it out, please share your technique.

Otherwise.... +1 on the Toecutter suggestion.

Be aware that successfully installing the 90-degree valve (so they seat properly and don't leak!) is often no picnic either.

So make sure it's worth it to you prior to taking the diagonal cutters to your existing stems....

There is a tool for installing rubber valve stems, but you wouldn't want to use it on nice painted rims without protection. It screws onto the stem, then leverage is used to pull the soaped stem through. For removal, Toes illustration says it all, cut and rip.

IIRC, the stems are pulled in from the back side of the rim with a tool the screws onto the threads that hold the cap on, and removed with side cutters..... see above ^^^^

Straight Valve insertion tool;

For the installation and removal of "snap-in" type tubeless tire valves.

Tool is screwed on to the valve and leverage is obtained against the rim and the valve stem is pulled through.

I will be doing this soon, looks simple enough in theory Any tips or tricks?

The ones I got from BikeEffects fit perfectly. They mated up with the rim, and screwed together. The threads were pre-gunked up with a sealer/loc-tight kind of stuff. The only issue I had was finding a cheap enough socket that was thin enough to do the nut and not bind up on the opening on the inside of the rim.

Was a piece of cake, and tires haven't lost an ounce now in 3 weeks so I'm real, real happy.

Based on Warchilds comment I decided to be extra careful. I used the alternate method list in the instructions and removed the grommet from the valve stem and put it in the wheel first. Then threaded the valve stem into the wheel. I feel pretty confident it has a good seal.

OK good. somehow its always the simple crap that seems to give me the most heartache

I've found using a large dual-sport BMW is helpful.

Having a dedicated tool to screw onto the stem to pull it through the hole is convenient but not necessary. Just thread a nut onto the stem and then use some pilers and scrap pieces of wood for pry points.
