Paint & Surface Preparation / Protection Recommendations for Locomotive 6167
A. Boiler
All surfaces must be free of rust, cleaned, particle blasted and phosphatized prior to painting.
Use red oxide primer-sealer. Allow a minimum of 1-hour air drying time before applying a re-coat. Dry film thickness to be 2.0 to 2.5 mils. Exterior top coat finish to be gloss black. Allow a minimum of 1-hour drying time before applying a re-coat. Dry Film thickness to be 2.0 to 2.5 mils. - A needle gun may necessary to remove excessive rust/corrosion before cleaning/blasting.
B. Boiler Jackets & Bands
All surfaces must be free of rust, cleaned and phosphatized prior to painting.
Use black primer-sealer. Allow a minimum of 1-hour air drying time before applying a re-coat. Dry film thickness to be 2.0 to 2.5 mils. Exterior top coat finish to be gloss black. Allow a minimum of 1-hour drying time before applying a re-coat. Dry Film thickness to be 2.0 to 2.5 mils.
C. Turret Cover, Dynamo, Sand Domes, Steam Domes, Reservoir Tanks, Pumps, Stations, Grab-rails, Walkways, Steps, Pipes.
All surfaces must be free of rust, cleaned, particle blasted and phosphatized prior to painting.
Use red oxide primer-sealer. Allow a minimum of 1-hour air drying time before applying a re-coat. Dry film thickness to be 2.0 to 2.5 mils. Exterior top coat finish to be gloss black. Allow a minimum of 1-hour drying time before applying a re-coat. Dry Film thickness to be 2.0 to 2.5 mils. Sand blasting is acceptable as these parts are currently removed from the locomotive.
D. Cab Exterior
All surfaces must be free of rust, cleaned, particle blasted and phosphatized prior to painting.
Use red oxide primer-sealer. Allow a minimum of 1-hour air drying time before applying a re-coat. Dry film thickness to be 2.0 to 2.5 mils. Exterior top coat finish to be gloss black. Allow a minimum of 1-hour drying time before applying a re-coat. Dry Film thickness to be 2.0 to 2.5 mils.
E. Smoke Box, Chassis & Frame, Wheels, Sheet metal, Brackets and Miscellaneous Structures, etc.
All surfaces must be free of rust, cleaned, wire wheeled or blasted and phosphatized prior to painting. Use red oxide primer-sealer. Allow a minimum of 1-hour air drying time before applying a re-coat. Dry film thickness to be 2.0 to 2.5 mils. Exterior top coat finish to be gloss black. Allow a minimum of 1-hour drying time before applying a re-coat. Dry Film thickness to be 2.0 to 2.5 mils. A needle gun may necessary to remove excessive rust/corrosion before cleaning/blasting.
F. Tender
All surfaces must be free of rust, cleaned, particle blasted and phosphatized prior to painting.
Use red oxide primer-sealer. Allow a minimum of 1-hour air drying time before applying a re-coat. Dry film thickness to be 2.0 to 2.5 mils. Exterior top coat finish to be gloss black. Allow a minimum of 1-hour drying time before applying a re-coat. Dry Film thickness to be 2.0 to 2.5 mils. . A needle gun may necessary to remove excessive rust/corrosion before cleaning/blasting
Acceptable Quality
All surfaces are to be uniformly covered with paint. The primer and top- coat are each to be 2.0 to 2.5 mils thick when dry. Primed surface must be smooth and hard. The top coat surface must be smooth and hard. The topcoat must have a uniform and constant gloss.
Unacceptable Quality
Runs, sags, brush strokes, lack of gloss, painting over rust, scale, dirt, grease, oil, etc.
Failure to obtain full paint coverage of a minimum thickness of 2.0 mil will be considered unacceptable.
Protection of Threads and Machined Surfaces
Threaded surfaces must be protected from paint via plastic caps or plugs.
Machined surfaces must be protected from paint via masking tape or masking dope.
Deviations
Consideration will be made to the following areas: Locomotive & Tender's chassis(s), wheels assemblies & axles, where it may be impossible to position personal, blasting or painting equipment.
Soda/ Sand / Particle Blasting Surface Protection
Protection of Bearings, Bearing Surfaces, Machined Surfaces, Polished Surfaces, Piston Rods
& Glass Surfaces
NOTE (1) : It is of utmost importance that any and all bearings or bearing surfaces and grease fittings be protected from all foreign matter.
Liberally stuff rags (tightly) around axles (journals) between hubs and boxes. Rags can also be stuffed into journal boxes on tender. Journal lids should be made to seal well to box by cutting rubber gaskets, if required.
On driving wheel journals (except #2 set), driving box lubricators (cellars) can be stuffed with rags.
Engine truck bearings are of the inside-frame roller type. Rags should be wrapped around axles on both sides of bearing races.
Trailing truck bearings are of the outside-frame roller type. Rags should be wrapped around the axles on inside of bearing races.
NOTE (2) : PISTON RODS AND VALVE STEMS WILL NOT BE PARTICLE BLASTED, AND MUST BE WRAPPED WITH RAGS, INCLUDING INTO GLANDS. To avoid damage.
The channel or cross-sections of the crosshead guides, to be stuffed with rags.
Valve guides crosshead to be stuffed with rags.
Rags to be stuffed in whistle shutoff valve flanges to protect steam rings.
If the links, blocks, reverse shaft, and all rods are not removed, all respective bearings must be protected.
Air compressor piston rods are to be protected between gland nuts. Gland nuts are also to be sealed.
Water pump piston rods are to be protected between gland nuts. Gland nuts are also to be sealed.
All brake cylinder piston rod glands are to be wrapped with rags.
A piece of plywood (¼") should be cut to the diameter of the bowl of the whistle and placed between the bowl and the bell, which will be tightened down against the plywood. The whistle will not be removed.
All grease fittings will be fitted with plastic caps, or can be removed and grease cavity fitted with plastic plugs (same as above), or replaced with ¼" pipe plugs. Grease fittings must be saved.
All brass identification plates (right side feed water heater; right rear of frame cradle; trailing truck bearing inspection plates (4); power reverse cylinder) are to be covered with heavy tape cut to fit.
Rags to be wrapped around blower valve bonnet and gland.
NOTE (3) : on surfaces such as pins and piston rods, rags can be secured to be these by applying wire, cord, steel strapping, etc.
Tender tank valve assembly will be wrapped with rags.
All glass surfaces must be protected.
Rustoleum branded paint products are requested, specific product key codes to be advised.
