The Troy Bilt 42000 is a 21-inch walk-behind snowblower designed for residential use to clear driveways and walkways. It features an electric starter with recoil starter backup, hand controls and a rotatable discharge chute. The 42000 operates in three forward speeds, neutral and a single reverse speed. This snowblower is powered by a 5 horsepower, four-cycle Tecumseh HSSK50 Snow King engine. Troy Bilt's owner's manual refers to the Tecumseh HSSK50 owner's manual for oil specifications.
Tecumseh recommends use of a high-quality brand name oil with a classification of at least SL/SJ. In a temperature range of minus 20 degrees Fahrenheit to 40 degrees Fahrenheit, standard multi-grade SAE 5W30 oil is recommended. A synthetic SAE 0W30 oil may be substituted, if desired. For temperatures above 40 degrees Fahrenheit, use single grade SAE 30 weight oil. The engine oil capacity of the Tecumseh HSSK50 is 21 ounces.
Oil Maintenance Schedule
Tecumseh recommends checking the oil before each use. Oil should be changed after the first two hours of operation and after every 25 hours from then on.
Check The Oil
Place the machine on a level surface. Clean any dirt or debris away from the dipstick/oil cap located at the top of the oil fill tube on the right side of the engine. Remove the dipstick/oil cap and wipe the dipstick clean. Reinsert the dipstick and tighten the oil cap securely. Remove the dipstick again and read the oil level. Top up with recommended oil to bring the level to the "Full" mark on the dipstick.
Change The Oil
Clean dirt away from the oil drain plug at the bottom front of the engine crankcase. Place a pan under the plug and remove the drain plug and the oil fill cap on top of the engine. After oil has drained, replace the drain plug and tighten securely. Fill the crankcase with the recommended oil. Replace the oil fill cap.
