injector problems still

I doubt our water gets that hot, but our injectors stop working anyway. None of them are lifting injectors, they're all horizontal ones below the footplate so they're also below the level of the tender tank bottom.

We do the same thing leaving the water flowing through the injector the whole time.

Apparently we have a maker of reliable, high quality injectors here in Aus, two of which I have waiting for my NSW mogul. I don't want to try them on my current loco in case they get contaminated somehow!

Hi Ron,

A very impressive setup! Those are very big locos.

My father-in-law goes to a place in Qld where the bloke even makes scale bricks to make the buildings with, scale signals, etc.

Hallo Ron,

I am Werner from Germany and I had experience using john Cashmores injectors at 3 locomotives without any problem. The day came on a club track the injector failed.

For me it was clear the injector is the problem. The Boiler check valve was OK. At home I tried from my other

locos perfect working injectors and they failed in the same way. At each time the injector want to start suddenly a steam water spray came out of the injector.

I decide to give a try with a silicon pipe with a water valve between in a external test pipe.

The injectors worked all very well. Then I test with the orignal valve from the loco with the silicon testpipe.

And the failure was very clear, if the injector trys to start and failed there were many many very small air bubbles

to see. That was the reason why the injector failed. The water valve wa water tight but not air thight.

I replaced the water valve and the injectors worked very well again.

That is what I learned from practice. And I have later learned to built injectors by my own with many try and error

but the work in the same way as the copied comercial ones.

best regards

Werner
