Information for removing the tender is contained on page 19 of the Spectrum Two-Truck Climax Operator's Manual.
Following procedure copied from page 19 of Operator's Manual.
*Loosen the two recessed Phillips head screws located under the tender water valves (access the screws by simply lifting the water valves off).
Note:screws may be tight.*Tilt the coal bunker backwards until the tabs on the back of the bunker release.
*Lift the bunker shell up and off.
That's it. When lifting the bunker off pay attention that one or both of the sander lines are not lost. They are small and if dropped might be difficult to find.
Went out and took a picture on one of the Climax locomotives showing the location.
