How goes Bill what is OMS, and what springs did you buy to replace the old with, can you get a good picture of the piston work? I have two, one is my daughters had a spring pop out and cannot find it LOL, either repost or send it to my email,  How's that turbine coming? post that on the PRR thread when done like to see it. Mark

Mark, sorry about the OMS abbreviation. I was an industrial chemist for years and we're all about such abbreviations. It is Odorless Mineral Spirits. I like it as it is somewhat less toxic as it contains fewer carcinogens than standard paint thinner (and won't smell up the house giving it a better SAF, or Spouse Acceptance Factor). You may already be using it.

For the piston guides, you will have to remove the sidegear so you can slide the pistons out of the guides. Both the pistons and guides are plated castings and it seems the casting dimensions didn't account for the plating, at least on my loco. By hand, gently slide each piston back and forth in its guide and "feel" where the piston gets tight, probably near the "full compression" position. You can then VERY gently file the front of the piston casting groove a TINY bit wider and deeper. Also, a bit of GENTLE filing on the top and inside of the lower guide rail toward the front of the loco may be needed. The filing I did was so slight, I can't imagine a photo would show it (which is actually good) but it pretty much eliminated "surging" at low speed.

While you've got the sidegear off, you can remove the bottom plate and put the new stiffer springs in under the center driver bearings. The springs are from D. R. Templeman, part # CAT-0250-0023-S. Templeman is a great place to get small springs for just about anything in model railroading.

While I love this 0-6-0 Dockside switcher, one thing I've GOT to say is that the whistle is TERRIBLE! It sounds like a horn! If anyone has been able to fool with the sound electronics and get a real whistle installed, please post!

Finally, the Turbine motor armature is with the Motor Doc. He's had it a week but I don't know how busy he is so the rewind might take awhile...
