Bachmann 3 truck shay
Posted by chocho willy on Tuesday, November 20, 2018 10:48 AM

draw bar Just purchased and received a new 82498 3 truck Bachmann 1:20 shay and found the draw bar is installed backwards as the end with the 2 holes is mounted under the main chassis of the engine, it is mounted in the farthest hole which means that it should run tight turns ok but was wondering if these is a mistake or done on purpose as maybe they were having problems of people running the wrong hole and having problems. Another thing I noticed is that on the main frame end the draw bar has a coiled spring on it that is on the up side of the bar and pushes the bar down, and being as the water car part attaches to it and the post with the screw in it isn't too long should the spring be on the under side so that it pushes up on the bar instead of down. Any input would be appreciated as I have contacted Bachmann and haven't heard back from them. Also viewed the DVD and was wonder what every one else uses of lubricants or where to by the Bachmann ones ? Bill

Supposed to be that way. In the original review, we surmised the reason, then it was confirmed by Howard Lee Riley at Bachmann.

The issue was on tight curves with heavy train you would snap the plastic u-joint between second and third truck.

Shipped that way to ensure the purchaser/hobbyist/end user was full aware.

Instructions at the time were to remove bottom cover of end beam on main loco chassis, flip the drawbar around and re-assemble.

Can't recall on the spring, but assembled on track, if the drawbar is fairly level leave it alone.

I think if spring on bottom, drawbar will bind on end beam and angle way down.

You did get the bit about hot gluing the wires from harness to circuit board above second truck and securing to slots in chassis with wire ties?

Hope so, or that you at least took pictures to fix it later. Maybe Kader finally read the review and fixed that. I know when I reported it, HLR was furious, as he said he had instructed the factory how to fix that.

Lubricants? Fash in the pan. We all figured that and just used (from the beginning) plastic compatible oils and greases like LaBelle.

Curmudgeon, thanks so much for your reply and no i didn't see anything about hot gluing the wires in the provided DVD and sort of figured that the draw bar was install backwards on purpose sort of dumbing it up for some who don't follow directions. As far as the spring if it was the other way around it would probably prevent it from uncoupling but then the bar would rub on the wires coming from the 2 truck and after testing on some up and down track it doesn't seem to even want to come uncoupled. Would be interested in where to go to get information on on the hot glue thing. Don't know if you have seen it or not but on LSC under "skunk train" Scott Johnson has posted his pictures of his train and it is built around the 3 truck shay but is painted red, quite a site to see, thanks again Bill

I am searching for the data to copy and paste...so far no joy.

The issue would be visible when you remove the fuel bunker over second truck, no need to connect the third truck and water bunker, but looking down on the circuit board, right rear, move the plug on the end of the harness full swing left to right and see if any wores move at the circuit board.

Typical smal number of wires cost saving PRC, and NO strain relief in soldering (NASA certified?) the wires in the un-tinned section between board connection and end of insulation will "brillo-pad" and fail.

Resolder any failed connections, then lift wires and hot glue under them, pressing back onto board, then hot-glue across the top.

Find the unused slots on the floor just forward of the drawbar mount, cross the wires and using small zip-ties, affix them.

Oh, and if your third truck is uncoupling from the drawbar......I have never had that happen here.

Again thanks, I think from your written description I should be able to do ok, Bill now all i have to do is find my hot glue gun
