The key to continued optimum performance from your K-27 is regularly scheduled maintenance. Your new K-27’s gearbox was lubricated at the factory. However, the running gear will require lubrication before you run it for the first time. Failure to perform this initial lubrication may result in damage to your
locomotive. So please follow the lubrication procedure carefully.
You should lubricate your K-27 after every 10+ hours of actual running time, or as needed. The product engineers at Bachmann designed the K-27 in such a way that only a few simple steps are needed to prepare it for operation.
We recommend high quality lubricants designed for operations outdoors, such as Bachmann’s line of E-Z Lube® products. To begin, be sure to choose a large, flat, sturdy surface on which to work. Use the foam top from the K-27’s packaging as a cradle for your locomotive. Next, turn the locomotive upside down and gently place it in the foam cradle so you can easily access the wheels, axles, and valve gear (as shown in figure 1).
Begin lubrication at the front of the locomotive and work towards the rear, starting with the front truck. From there, move on to the valve gear, axles, springs, bearings, and wheels, and finish with the rear truck (figure 1).
NOTE: There are lots of bearing surfaces on the K-27 running gear. Be sure to take your time and lubricate all of them. For the purposes of illustration we are only going to lubricate one side of the running gear. Don’t forget to lubricate both sides.
Beginning with the front truck, use heavy viscosity oil to lubricate the plunger and points where it contacts the locomotive frame (figure 2). This will help it to move easily in either direction. Next lubricate the axles where they pass through the truck side frames.
Moving on to the double hung valve gear, use heavy viscosity oil to lubricate all of the bearing surfaces where metal contacts metal (figure 4). There are a lot of them, so take care to get them all. Remember to lubricate the valve gear on the other side as well.
Again, be sure to lubricate both sides of the running gear. By establishing a regular lubrication schedule, you can have a lifetime of fun, performance, and satisfaction with this locomotive model. Remember, this locomotive performs best on curves with a minimum 8´ diameter.
