stuck cylinders

hi chaps, this is my bad due to forgetting to oil the cylinders after using the loco last year. My royal scot as stuck cylinders, all three. I have opened up the cylinders to see inside and there is a small amount of rust to be seen along the bore. I have tipped up the front of the loco on blocks and filled the cylinders with freeing oil.

apart from removing the motion from the cylinders and tapping the pistons lightly I am not sure of the best way to free off the cylinders. I don,t have excess to lots of heat bar propane gas. anyone had this problem and worked it out. michael

I had the same problem about 16 months ago. This is the thread "Rust in CI Cylinders" that covered my problem.

Sorry - don't know how to do a direct link but I guess you can search for the thread.

Here you go **LINK**

Thanks chaps, so it looks like off with the motion to free the piston, then oiling well after. michael

hi chaps, thanks again. today I was able to free off the two outside pistons. by undoing the crosshead bolts I was able to just tap lightly the piston with a bit of cut off wooden handle. there was very little sign of rust but I cleaned off what I could see with a bit of t cut and oiled the cylinders. so it looks like the inside cylinder is the fault. I need to wait until her indoors comes home so we can place the scot on its side. I have raided the house for all the old pillows, well I hope they are old. in the mean time I am going to mark all the motion gear before it gets moved about to aid correct positions when I put it all back together.michael
