When travelling the out back I guess we can all plug a punture, Change a tyre on a rim and change a wheel but what do people if they need to change a valve. I had a valve rupture and fortunately had spare wheels which aI could change too. Ironically I also had spare valves but no knowledge on how to chnage these.
How do you do it?

G'day Noel
You made me think - don't do that too often - gives me a headache. Anyway, had a look at Google and hey presto - I reckon I could change a valve stem now. And like you I casrry spare valves and stems and the plugs (touch wood - never had to use any of them)
Valve stem change
Cheers (and thanks for getting me thinking again)

The rubber ones you just pull through the rim with pliers. Havent you ever stuck around when the tyre place fits new tyres?
if you cannot manage that, buy steel shank ones with a thread and gasket and just pass it through from inside and tighten up the thread onto the gasket of course.
But you raise a good point that few of us would ever carry spare valve complete assemblies, just the cores. I have never had one fail or seen one fail but I guess it is possible. You could probably get away with supergluing it together.

I would reccomend your comment about steel shank ones Philip.
Had to replace one once on the track , had 2 new rubber ones , but they require considerable force and easy to damage , when wind and rain and mud are about.
Not sure rating but think the rubber car ones are also only good for 65psi or so and I always carry spare at at least 75psi.

Robin, someone with your knowledge I thought you would know the issues of using steel valve stems in off roading.
For some reason steel ones don't flew like rubber when hit.

Agreed Olcoolone - but the compromise is required sometimes to ensure the basic result is first achieved, optimization can come at the next garage.

Try some lubricant around the rubber valve stem, it works a treat.

Hi Noel,
I do carry some spare valve bodies as
well as valve stem inserts.
I would worry about pulling the valve through the rim using pliers though. There is risk of damaging the valve and especially the thread.
The valve and hole should be lubricated with soapy water or detergent before pulling the valve in. Also apply thumb pressure from inside the rim whilst pulling.
Rather than using pliers, insert the valve loosely then screw-on a 4-way valve tool (see
pic below) and use that to pull and wriggle the valve through the rim hole.
The valve tool is also used to remove & replace the inner valve and to rethread the outer and inner threads should they need it. A useful thing to have in the toolbox, readily available and cheap.

I buy all of my tyre repair gear (especially consumables such as patches, glue, valve stems, etc) from Rema Tip Top

Any half-decent tyre outlet should stock at least some of their stuff..........

Another tip.
Using the 4 way tool shown above you can get a bit of extra pull using a claw hammer. The claw goes under the cross and the head of the hammer levers on the rim.
The guys at the tyre dealer have a tool that screws onto the valve stem and uses a fulcrum/lever system to pull the stem into place.

Hi all,
Valve Core
tools are readily available at Auto acc's shops like Supercheap Auto, Autobarn, etc. Five or ten dollars should see you with a tool and several spare valve cores.

Hang-on....... I just remembered...... it has to do with "shoulders" of the inner valve.
A free inner valve to anyone who knows the correct answer.

Gday Allan,
I thought it was for cleaning dirt and
debris out the inside of the valve stem before removing the core.

Can't remember having had to do that, but apparently it happens ;-)

OK......... It's an Easy-Out To remove the inner valve when the "shoulders" that engage the normal removal tool have been sheared-off or damaged. Neat hey?

Well done.
I cannot remember needing it either , but you never know. I never did need to remove a pebble from a horses hoof with that thingy in my pocket knife either!
