Weaver FA truck side frame removeal

put a small blade screwdriver into the bolster slot to release the sideframe stud at the notch. then pull out.

you might also want to file a second smaller notch on the top of the stud to allow better equalization of the truck.

Hi John (Chris),  Thanks for the note but I must be dumber than a stone because I have not found a slot near the post that holds the side frame in that will accept a screw driver.  I'm looking from the top of the truck just outboard of the truck attaching screw hole.  Is this slot at the bottom of the channel that supports the pivot screw at the center of the bolster just to the inside of the wiper when viewed from the top.  If so, all I see is a square hole, the wiper and the pivot post from the side frame.  Do I have a different truck or should I be looking from the bottom???? I just don't see it.  Should I use a hammer?  Please advise.  Thanks!  Jim S    

I insert a pair of needle-nose pliers from the underside of the truck, in between both studs in the center of the truck, then open out the pliers. One or the other, or if you're lucky - both sideframes will pop out of the locating frame.

the small screwdriver blade goes in the channel on the underside of the truck.    Put it in sort of parallel to the bolster with the  blade underneath the end of the mounting pin.    A slight twist will usually pop the pin loose.

You need to perform the extraction with the loco upside-down on its roof.  The truck bolster is molded with a U-shaped channel on its underside.  Each truck side has a protruding shaft which snaps into the bolster.  These stub shafts are visible in the channel, they don't quite meet in the center, there's a gap which is the point of purchase for your tool.  Either the screwdriver or pliers method described above will work.  After the first couple of times the side frames get a little looser and will pop out easily.  Hope this clears things up!

You might consider wet tissue packed around the area where the wiper meets the plastic side frame.  Once you've done this to both ends of the wiper you should be able to solder a new wire to the wiper.

Thanks to one and all for your input.  Side frames are off!  By a stroke of desperation I put one jaw of a long nose plyer on the post end of the side frame and the other jaw on the square hole on the bottom side of the bolster and squeezed.  Off came the side frame with little effort.  Thanks again!  Regards,  Jim S.
