Bowser 4664 Challenger trailing truck wheel istallation
Posted by Wolf359 on Wednesday, January 10, 2018 12:16 PM

I recently got a used Bowser 4664 Challenger and noticed one of the wheels on the trailing truck was not spinning well. I attempted to gently clean where the wheel inserts, and the truck snapped. I have a replacement truck, and I would greatly appreciate some pointers on how to correctly install the wheels on the new truck. Thank you.

I haven’t had a Challenger but I did have a Big Boy for many years and the trailing truck is the same on both.  I didn’t have a problem removing and reinstalling the wheels.  Could the truck frame have been cracked when you got it?  The frame is pretty durable.  Examine the break in the casting to see if part of the break is discolored indicating it had a crack in it before you got it.

I have a kit at home; I could take a look sometime this weekend.

These parts probably haven't been made for quite some time. Spreading the casting to get the axles in is risky with old zamak. I would make a groove from the bottom of the truck up to the bearing hole with a file or a Dremel tool so that the wheelsets can be inserted without spreading the casting. After the whellsets are in position glue a thin strip of styrene across the groove at the bottom of the truck to keep the wheels from falling out when the engine is picked up.

Well, I pulled out my Challenger kit, and the rear wheelsets are already inserted.  If you go easy you may be able to spread it enough to get wheelsets in.  You could always ask Bowser.  Maybe Darth Santa Fe knows, he's built most of these kits.

Sorry about thatEmbarrassed. The replacement truck came in a V shape so the wheels could slip in to place easier, so I heated the truck a little bit with a hair dryer on its highest setting and gently squeezed it to the correct shape and held it together with a rubber band overnight. I also put spacers between the ends of the axles and the inside of the truck as the wheels were too wobbly from side to side.
