Tyrepal locking nuts.

I have just spent over an hour replacing the batteries in my tyrepal tpms system.
The problem was the locking nuts that tighten up behind the sensors, I will never use them again.
I finished up having to use a wrench to remove three of the sensors with the nuts still in place.
Fortunately I managed this without damaging the sensors.
Even with the sensors removed the spanner supplied could not remove the nuts. I had to use the wrench to remove them from the valves also. Bottom line I just removed the sensors without removing the nuts anyway.
Ok without a wrench or you have hands with a vice like grip I could not have done this.
So I have simply used the wrench to slightly tighten them, as to make it difficult to remove by hand.
Job done. :)
 
Good you are sorted :)

I have had similar issues with sensors and with removing metal dust caps as well when trying to service wheels on various random vehicles.
The method I have found works best rather then trying to undo them and damaging the tyre valve stems is get a dremel with a cutting disk and make a little groove in the nut- or the dust cap. Only a mm or so in, doesn't have to be all the way.
Then put in a flat-blade screwdriver into the grove, and give it a little twist. The metal will have been weakened enough by the cut that the torque of the srewdriver twist will snap it open and loosen its attachment on the valve head thread and can be spun off easily :D

The current TyrePal range no longer includes the lock nuts.

I suspect that they caused a lot of pr

yep all sorted
 
I just applied a little vaseline on the valve thread and lock nut every time i need to remove a sensor. No issues so far
 
I had to change the batteries in mine earlier this year. I didn’t have a problem but I think I will follow the example of iandsm and take them off (or loosen) to apply some Vaseline.
Not like I don’t have the time available at the moment and it will protect me from inflicted jobs for a while.

I just renewed batteries recently, not had a problem unlocking the thin nut so I’ll leave them as they are for now.
 
As POI Admin says the latest Tyrepal versions do not have locking nuts.

The metal dust caps on both the car and motorhome were never a problem because they got removed every week when checking the tyre pressures.

Regular maintenance which in my simple mind includes tyre pressure checking prevents problems.

Yes but of course if you have the reading on the Typrepal monitor you k now exactly what the pressures are so what"s the point of using a tyre pressure gauge to check it again. Perhaps that's why people tend to leave the sensors in place for longish periods.

The second and third line in my post was in relation to metal dust caps mentioned in a previous post and not the Tyrepal system.
 
A quick squirt of WD the evening before a job like that can be 5 minutes well spent. Although I had to drill out a sheared bolt the other day so my 5 mins the evening before was an utter waste of time! :rolleyes:
 
There are all kinds of wd type products out there this is one I saw for sale a few days ago
