Preparing the InterMountain AC-8/10/11/12 Steam Locomotive for Operation:
E ery InterMountain AC-8/10/11/12 Steam Locomoti e is factory tested prior to release. The InterMountain
AC-8/10/11/12 Steam Locomoti e is factory lubricated on all internal dri eline components. The external
dri eline components are not factory lubricated to protect the finished model in its presentation packaging.
Once initial set-up and test run is complete the following lubrication is required prior to normal
operation of the locomotive:
•Using high quality plastic compatible lubricating oil, carefully (but sparingly) lubricate all mo ing parts of
the external side rod assemblies. InterMountain Railway recommends Labelle® 108 - Synthetic Oil Multi-
Purpose Light Weight.
•Lubricating the dri e axles at their bearings is also recommended (see image below).
•A oid and remo e any excess oil prior to normal operation of the locomoti e.
Lubrication Locations
DC (Basic Analog Mode) Operation:
Operating the Locomotive with a standard N Scale Compatible (DC Analog) power pack:
•Set the DC Power pack direction control switch to forward.
•Set the DC Power pack throttle to Zero/Stop position.
•Turn on the N Scale Compatible DC Power pack.
•To Accelerate: Ad ance the throttle control slowly until the locomoti e mo es forward. Adjust the throttle as
required to achie e the desired speed.
•To Decelerate: Reduce the throttle control slowly. Adjust the throttle as required to achie e the desired speed.
•To Stop: Reduce the throttle control slowly to the Zero/Stop position.
•To Re erse or Change Direction: With the throttle in the Zero/Stop position, change the power pack direction
control switch to re erse or opposite position. Then accelerate, decelerate, and stop as described abo e.
Important Notes:
•NEVER Re erse or Change direction while the locomoti e is mo ing as this may damage the dri eline
components.
•A oid rapid throttle changes and abrupt stops to reduce excessi e strain on dri eline components.

Digital Command Control (DCC) Installation & Operation:
Your N Scale AC-8/10/11/12 is equipped with a 10 pin NMRA compliant plug for the installation of a decoder
in your locomoti e. The following instructions will guide you in the installation of your decoder. To install a
decoder in your AC-8/10/11/12 locomoti e requires only the remo al of the tender body.
1.Prepare the locomoti e by placing it on a protected surface. The foam pad included in your presentation
package would work just fine.
2.Remo e the tender body by inserting a flat tool between the edges of the body and sliding it back and forth.
This will release the body from the base frame. You will need to do this on both sides.
3.Remo e the tender body, being careful not to pull on the tender light wires.

4.Remo e the NMRA dummy plug and plug in your decoder. Align Pin-1 from the decoder (orange wire) to
Pin-1 on the plug (marked with a *1). Backwards installation of the decoder is harmless and will only result
in the locomoti e operating opposite to the direction indicator on your DCC system.
5.Replace the tender body.
Operating the DCC Equipped Locomotive with a qualified NMRA Command Station:
•Select the factory default locomoti e address. (Address 3 with most brands of decoders)
•Set the controller to the preferred speed-step range.
•To Accelerate: Ad ance the throttle control slowly until the locomoti e mo es forward. Adjust the throttle as
required to achie e the desired speed.
•To Decelerate: Reduce the throttle control slowly. Adjust the throttle to achie e the desired speed.
•To Stop: Reduce the throttle control slowly to the Zero/Stop position.
•To Re erse or Change Direction: With the throttle in the Zero/Stop position, change the direction control to
re erse or opposite position. Then accelerate, decelerate, and stop as described abo e.
Important Notes:
•NEVER Re erse or Change direction while the locomoti e is mo ing to a oid damaging dri eline
components.
•A oid rapid throttle changes and abrupt stops to reduce excessi e strain on dri eline components.

Ongoing Maintenance Activities:
Apply the following recommendations as needed.
Cleaning Wheels:
Use a small amount of rubbing alcohol as needed to remo e most normal build up on wheels. The
frequency of wheel cleaning can ary depending on factors such as track condition, duration of
running time, etc.
External Lubrication:
Using high quality plastic compatible lubricating oil, carefully (but sparingly) lubricate all mo ing
parts of the external side rod assembly. Lubricating the dri e axles at their bearings is also
recommended. Always a oid excessi e lubrication and remo e any excess oil prior to normal
operation of the locomoti e.
Internal Driver Set – Gear Lubrication:
After extended operational ser ice, inspect and lubricate the dri e gears in each dri er set with high
quality plastic compatible gear oil or light grease. Again, light application of the lubricant is best. An
experienced modeler or technician should perform the dri e gear lubrication as remo al and
reassembly of the dri er set co er plates and brake gear detail is required to access these components.
Drive Motor:
The Dri e Motor in this locomoti e is permanently lubricated and requires no additional lubrication.

Your N scale AC-8/10/11/12 comes with a pilot coupler con ersion allowing for issue free double-headed
operation. The extended coupler can be exchanged for a short shank coupler by following these simple steps:
1.Included in your locomoti e presentation box is a packet containing replacement couplers and traction tires.
2.Remo e the coupler from the package and assemble as shown.
3.Remo e the coupler mounting screw and slide the coupler out the front of the pilot.
4.Assemble the coupler in the box and reinstall by sliding the coupler into the front. Tighten the screw to hold
the coupler in place.

Traction Tire Replacement
Your locomoti e comes with traction tires on the leading dri er of each 'engine'. Each set of 4 dri ing axles is
called an 'engine'. There are two 'engines' on the Cab Forward. Should these tires need to be replaced, an extra
set of 4 tires is included. This process requires patience and the need to work extremely carefully. Do this
work on a clean work space so as not to loose any of the small parts. Please read through the steps below
before starting the work.
1. Included in your locomoti e presentation box is a packet containing replacement couplers and traction
tires. Ha e this packet handy but don't remo e the tires from the packet until you are ready to replace
them.
2. There is one traction tired dri er axle on both 'engines'. Replace the traction tires on one dri er axle at
a time. It is not required to replace more tires than necessary, howe er these instructions are the same
for the traction tired dri ers on both 'engines'.
3. Using a small pair of side cutters, slide the cutter head between the hex-head pin holding the side rod
to the dri er and the side rod. This is a press-fit hex-head pin and NOT a screw. Do not cut the pin
with the side cutters! Use a small flat blade screwdri er under the cutters. Twisting the screwdri er
while pulling STRAIGHT up on the pin with the cutters will release the pin. It is extremely important
that the pin is pulled STRAIGHT up and completely out without rocking it. If it is rocked, the hole that
the pin fits into will elongate and the pin will not hold when re-inserted. Set the pins in a safe place as
they'll be re-inserted later.
4. Do the abo e for both sides of the dri er.
5. Turn the locomoti e upside-down and gently pry the brake hanger off the bottom of the 'engine' you
are working on with a small flat blade screwdri er. Pull it straight out.
6. Remo e the two Phillips head screws and remo e the bottom plate from the dri ers. The traction tired
dri er can now be pulled out. No other dri ers should be pulled out.
7. Using a #11 X-acto blade, scrape out the old traction tire from the groo e. Be sure to clean the groo e
completely or the new traction tire will not lay flat causing the locomoti e to wobble.
8. Remo e one new traction tire from the included package. Using a round smooth pointed tool, re-install
the new traction tire. The tool will help guide the tire into the groo e. Make sure the tire is fully seated
and does not twist as it is going into the groo e. It should be completely flat in the groo e. Install one
tire completely before doing another one (if necessary).
9. Set the dri er back in the locomoti e with the hole for the pin aligned to the side rod, and re-assemble
the locomoti e in the re erse order from abo e. Do not try to turn the wheels on the axle to align the
pin holes. If the wheels get turned on the axle, they'll ha e to be re-quartered.
10. Re-insert the hex-head pins last. Be extremely careful to re-insert the pins into the side rod and dri er
completely STRAIGHT!
If you should elongate the hole in the dri er and the pin will not hold, a replacement dri er is required.
Contact us for information on a ailability of replacement dri ers. Limited supply. There is a fee for a
replacement dri er and is subject to a ailability.
