running conditions. Replace any other piping such as the blower pipe. Replace the smoke box
front and the door. It is important that the front be scaled tighL The engine being an oil burner
requires that the front end hold a partial vacuum to operate properly. J'o test the front end the
boiler must be assembled in an operational condition. Apply air to the firing manifold to induce a
~ draft through the blower. Using an oxy-acetylene torch light only an acetylene flame. Do not
open the oxygen valve. You will need a small acetylene flame about an inch long with no
oxygen. The flame must be soft. Apply this flame on the areas that are sealed. That is at the door
g seal and the smoke box front joint. If there is a vacuum leak. the flame will be sucked in through
the hole. It will be quite obvious. Remember: do not use any oxygen with the acetylene flame.
You can move fairly rapidly with this test. If you have made any other new joints in the smoke
• box such as where a pipe enters check it also. Repair all leaks.
The next goal that you may aspire to would be the repair of the running gear. The tires are worn
Q and for operation on an FRA controlled road it needs to be determined if they can be turned or if
they require replacement. However for your immediate needs this issue can and should be put
a off. Proceed with the driver journal repair.
Block the engine so that it cannot roll or move during the following procedure. Drop the
0 suspension, block the driving boxes to the frame, and remove the driver's pedestal binders
wedges, and shoes. Prior to the removal of the wedges witness there location. This will give you
a reference for the reassembly. Although they wil1 require adjustment it wm be a place to start
D from. Save the shims on the shoes and be prepared to put them back as they came out. Drop out
the engine brake rigging rods so that the brake shoes hang away from the tire as the shoes will
impede the work on the drivers. Remove the side rod~. Place jacks for lifting the locomotive at
0 approximately the rear of the cylinders under the frame and at the rear of the frame in a
structurally significant location. It is appropriate to place a section of some structural shape
across the rails upon which the jacks will be placed. Jack the locomotive up high enough so that
0 when the driving box is lifted off the journal it is reasonably accessible for cleaning and
polishing. Block or crib the locomotive in this position. Do not rely on the jacks to support the
load for an extended time unless the jacks are specificaJly designed for this purpose. If the
D jacking procedure is of concern to you hire a professional company to jack up the engine. Clean
and polish the journals. It is appropriate to spin the drivers in situ to faci)jtate the job. To aid this
oil the railhead under the driver before spinning it. Clean the bra.~ses, lubricate with a heavy oil
and set the box on the journal. Do a particularly good job of polishing and deaning as the set up
to get here represent" a significant expenditure of time and effort. The height that you wiH wish
u to raise the engine should be in the neighbor hood of 10" to 14". It may be convenient to go a
little higher but you wi11 not need to go many feet up into the air. Once you have cleaned and
polished all six driver journals place hard wood blocks on the top of the driver boxes and set the
engine down.

Clean and repack the grease packs at this time. Use pindope. Talk to someone who works on a
large engine for a source of pindope. We do not use pindope as the Locomotives at our facility
l ! are oil engines.
( While this is in progress clean the side rods of paint and rust. Clean the bearings of old lubricant.
