Advice: Glue that is not permanent

This will probably work. I use this for sticking people down and they can be removed easily. Brush on a small amount and let it dry clear then stick it on. It’s basically a hobby contact cement. 

That hobby tac should work. Just give it a little time to tac...dry a little. 

Buy a new roller, it's supposed to clip in there, it shouldn't need glue.

Aleene's Tacky Glue at Michaels is a good item.

Tacky Wax will work better than the glue.  In time the glue will harden.. The wax will work great, and never harden enough so it can be easily removed..

Something like these:

I use a brand (not available anymore?) called "Tacky Tack" as I recall it. I've used it for years and the stuff never dries out. It's like a clay that sticks. I've used it to hold all sorts of things in my model railroading. Any changes needed, just pull it off and redo. No biggie.

Wax isn't something I'd expect to work real well as roller do get pretty warm and most waxes don't like heat at all.

A dab of silcone or plain old white caulk should allow it to be pulled apart "someday".

I don't know MTH trucks real well, but I'm guessing the clip legs/stays have warped from time or heat.  I've reshaped some if I recall (lionels for sure). Sometimes they broke and I used a "goo" as mentioned, but I also shim temporarily, so the set glue kinda wedges things; that holds the remaining leg(s) locked on the stays. I.e. it's almost a plug or "stop" vs an adhesive.

I would use a little rubber cement. Arnold

Yep, rubber cement or just a little dab of hot melt glue..

Thanks for the response. For the short term I will go with the temporary glue and then get a replacement part. My concern is that the insert plate issue is only a segment and I might need a new truck for everything to work as well as it should, which I will have checked at a later time. The car is from the MTH Lehigh Valley John Wilkes passenger set. I have the matching Weaver Black Diamond loco. It is awesome. I haven't run the set for a few years, so I am enjoying it.

Aleene's tacky at Michael's is an excellent glue to use for a strong long term hold yet razor blade or muscle snap  removable.  Yes, it is a Band-Aid but it is a very good Band-Aid.  Just use less than you might think for an easy clean up.  It drys clear.  

I have used it for road bed on bridges, adding ties at tie strip gaps, building repairs, broken detail parts, tool box compartments, instrument panel labels and many household patch jobs.  Ten years and holding strong.

Lift out bridge example:

1 1/4" gauge strip holds the bridge, the fitter piece and the  mainline in horizontal alignment ,  The weight holds everything in vertical alignment.

Glue sets up over night.  Absolutely no movement.

I use clear acrylic caulking for that type of application. It holds well, however you can also remove it. I use it to hold people inside my various passenger cars. I have also had to remove some of the people, no problem. It peels off similar to rubber cement.

Use Walthers GOO. When you need to remove, then use GOO GONE!
