As all my PS3 steamers eventually lose control or stop outright via DCS remote, ostensibly due to wireless drawbar pins coming just a tad loose at tender connection, I purchased the cover caps from MTH (part #FB0000028). I've been able to insert them successfully on a couple of steamers - but not on others. Is there a way the caps are supposed to be installed? I noted a white dot on the one end of the cap - I believe it is supposed to face down on the tender side. I am afraid to use too much force on these, or is a lot of force required sometimes? These drawbar pins coming loose at the tender plug is a real PITA IMO.

Hello Paul.   since you have been waiting two hours, Ill give it a shot.    If you are talking about the square black things with the hole in them that hold the drawbar to the tender pin ?  It will probably go on hard.  I use vinyl tubing for this job and it goes on hard, but also does not come off.

Your title may be a little misleading because there is a thin plastic cap on the drawbar surface, that snaps on.

Regarding the black plugs that MTH sells via parts department - ostensibly designed to keep the drawbar pin connected where it inserts into the tender...I had to hammer them on using wood block and small hammer, and before hammering I inserted a thin piece of wood between the top of the steel tender pole and the underside of the tender to provide backing. I think they're on pretty secure now

Have you tried Super glue ?  JK

I've not had one pull off / down yet, but I don't run them like crazy and for long periods of time.

I recently purchased a new MTH Premier steam engine with PS3. Within the first hour or two of operation, the engine suddenly stopped twice. Gently pushing the tender-end of the drawbar upward immediately got the engine going again. I then read about, and ordered, the retainer piece from MTH but, in the meantime, I bought some clear plastic tubing (5/16" OD - 3/16" ID), cut a piece about 1/2" in length, and placed it onto the tender drawbar post. The fit is quite snug. I've run the engine about four hours since then, and the issue hasn't recurred, so I've been continuing to run with the tubing. If it recurs, I will install the MTH part...

Fantastic idea !

One of the issues with the "wireless" drawbars on MTH equipment is the tender post has too much slop.  When it tilts toward the locomotive under pressure, that tends to work the connector loose.  I took one and added shims to it so that it just has room to swivel, and also canted it slightly to the rear.  It's previous bad habits were all cured without adding anything to hold it on the post.

I know it's been a couple months since the last post on this thread, but does anyone have photos of how they were able to solve this (e.g plastic tubing)?  I too have been experiencing this problem as of late (it does not help that I have ascending and descending track).

Similarly if anyone has suggestions for keeping MTH PS3  tethers connected between a Diesel ABA unit, I would be most appreciative.
