I have an Atlas Seaboard engine purchased new in the year 2000, p/n 6811-1. The part that I need is the screw that goes through the truck and holds the roller assembly in place. A wire connects to the top of the screw (under the head of the screw) for electrical contact to the roller. Unfornunately the thread has stripped, and no longer holds the roller in place. I have contacted Atlas, and have been told that they no longer support this product as the item has been re-designed. Since model trains tend to be around a long time, I was surprised by this response. I have taken the screw to a local hobby store, who handles a small amount of trains, but mostly deals in RC items. They did not have a screw to match this, but described the screw as " a number 2, which is 15mm long, pan head, phillips." (My measurements show this as 15 mm from under the head to the end and 17 mm long from one end to the other inclusive of the head) Any suggestions as to where I can find this screw, so I can put this engine back together. Thanks.

Thank you Jocko D. I heard from Atlas this morning and they found an SDP-35 in their place that apparantly has already been "cannabolized" for parts.....however, it still has the screws that I need so they are sending them to me. That being said the screw that I have that came out of my engine appears to be the problem as the threads look worn to me. Why this would wear, I have no clue, as it positions through the truck with a very tight fit, so there really is no room for it to move around. So.... once I receive the "new screws" from Atlas I will re-assemble the engine and hopefully put this "issue" to rest. If it is the roller assembly thread..........which hopefully it is not, then a new chapter starts! This really is a great engine, and I am anxious to see it together and back on the tracks working. Thank you for your offer of assistance, it is greatly appreciated.
