STEAM ENGINES.
All styles of engines both large and small should receive proper attention. All the vibrating and moving parts should be kept well oiled and free from grit and dirt. If this is neglected, the friction of the moving parts will soon wear away the metal and induce pounding and cause what is called “lost motion,” which detracts greatly from the power of the engine, and if allowed to run in this condition will soon necessitate large expense for repairs and shorten the life of the engine.
Tighten all the boxes as they wear, being careful not to get them too tight. Keep the piston rod and valve rod well packed with a good quality of soft packing. Keep the valve or valves set properly to give the required amount of lap and lead and an equal cut-off at the end of each stroke whether working in full gear or notched up.
Keep the cross-head shoes fitted properly in the guides, being careful to keep the piston rod in line. If the above instructions are followed, your engine will run smoothly and do good service.
