Help Replace Pickup Roller Asembly on MTH Passenger Car

If you find out, let me know!  I've found those to be a Royal PITA to install!  I ended up taking the whole truck apart.

I recently had a problem with a new premier passenger car roller assembly ... the plastic shoulder on p/n BD-0000062 was deformed which resulted in the roller pushing upwards (as car sits on track) and dislodging one side of the roller support.  That, in turn, caused the roller to cock itself sideways and it shorted on my switches.  Anyway, my solution was to "super glue" the roller plastic support shoulder onto the mating truck assembly metal support brace.  At the time, MTH parts was closed so couldn't order the $5 replacement roller assembly.

To access the BD-0000062 roller assembly, I had to remove the passenger car plastic body in order to access the screw that held the truck assembly onto the bottom metal frame of the passenger car.  Then I removed the whole truck assembly in order to access the BD-0000062 roller assembly.  This assembly snaps into the truck assembly metal frame (from the top of the truck assembly as viewed with passenger car sitting on your tracks).  Squeezing the sides of the roller assembly releases it from the truck assembly metal supports for removal.  To install a new roller assembly, one pushes the roller assembly into the top of the truck metal support frame; the roller assembly plastic side 'shoulders' snap into the metal support frame.

Here are a couple of photos: 1) image showing bottom of whole passenger car ... showing how the roller assembly was cocked due to one shoulder of the support arm of the roller assembly being deformed which led to shorting going through my switches, 2) image showing truck assembly removed from body of passenger car.  In this image, one can see drippings of the super glue that I used on left side where the roller assembly snaps into the truck support fame and 3) small image of MTH p/n BD-0000062 roller assembly.

Both mine were also painfully replaced.  See the following steps.  (The car is a UP Vista Dome built in 2003.

The tools to the right are most of the tools used to install the first roller assembly.

Here are the used and new roller assemblies.

The black mount holds the roller assembly on the truck frame.  As you inspect it there is a groove on each side that should just clip into place.

Fortunately removing the silver truck parts does not cause the truck springs to sproing away.

The old roller just twisted off from the right end of the frame.  The new one should twist and click right on.  NOT!

The second assembly took just as much skutching on as the first one and I bent the silver bracket the holds the roller rivet.   The scribe and the old stiff paring knife were used to coach the black mount into place.  The replacement black mounts appear to have under size mounts.

Closeup shows knife blade clearing path for black mount to clip on all the way.

The knife was used to open the length of the slot.
Truck screw and old rollers are on the right.

The black mounts might twist on and seat well if cold.   OR, buy new roller and rivet instead of roller assembly. (if possible)
Fortunately, those are the only rollers I have to replace on my UP Steam Excursion train in progress.

Yep, sounds about like my install.   They look like they should just snap in, but that was not to be!

Ref Susan's disassembly photos/description and my above 3 Oct post.

I was surprised to see Susan's description/photos of how much disassembly was needed on that circa 2003 passenger car truck.  

My roller assembly replacement was on a 2016-produced MTH premier passenger car ... MTH 20-41031.  Once I removed the truck assembly from the passenger car frame, I was able to squeeze the plastic shoulders of the roller assembly to free it from the truck assembly and then it was pulled upwards out through the top of the truck.   Glad I didn't have to totally disassemble the whole truck assembly.
