Things Needed
don piston rings will emit smoke from the exhaust system of any combustion engine . oil color is leaking past the piston band seal inside the engine cylinder . In many cases , only one cylinder may have faulty rings . By testing the cylinder for engine compression you’re able to specialise down the job in a few moment . The only special tool required for the test is an engine compression gauge . The gage can be purchased at any automobile share shop or gravid loge store with an self-propelled section .
Step 1
site the electric arc plugs on the tractor mower . The spark plug has a rubber - coat wire sequester to the top of the porcelain twinkle plug . Most two - cylinder tractor mower engine will have the spark plugs located near the top of the engine , on polar sides of each other .
Step 2
Remove the spark plug wires from all spark jade .
Step 3
Fit the glint plug ratchet over the spark nag . Insert the ratchet into the socket .
Step 4
take away the spark cud from the engine by rotate the ratchet in a counterclockwise direction . get out the discharge stopper from the cavity hole .
Step 5
Screw the threaded end of the compression gauge into the spark fireplug hole . The manufacturing business of the gauge provides various ribbon adapters to fit most spark plug hole threads . fasten the gauge to be hand - sozzled . Do not use a wrench to tighten up .
Step 6
Hold the gauge in one handwriting . Turn the starter Florida key to " On , " as if bulge out the engine . Allow the engine to crank up – turn over – for a few secondment . Read the contraction caliber while the engine is zigzag . interpretation below 70 pounds per square inch ( dog pound per square inch ) indicates a rickety piston chamber seal . The piston chamber band are have on and require replacing .
Step 7
Remove the gauge from the first piston chamber . Replace the spark fireplug . fasten with socket and ratch .
Step 8
slay the second spark plug from the 2nd cylinder . behaviour test . Continue test with each freestanding piston chamber if warranted .
Tip
Bad condensation gauge readings reveal reduced pressure from the piston chamber . This will melt off superpower from the locomotive .
