# How to Service a 12 HP OHV Tecumseh Snowblower Engine
The Craftsman snow blower, or thrower, comes with a 12 horsepower OVH Tecumseh motor. The engine has a durable build designed to withstand rugged winter conditions. However, to keep your Tecumseh engine in tip-top running condition, maintain the engine on a regular schedule. This includes changing the oil after every 25 hours of use. Change the spark plug at least once a year.
Things You'll Need
- Drip pan
- Pliers
- 1 quart 5-W-30 engine oil
- Spark plug wrench
- Champion RJ19LM spark plug

Place the drip pan beneath your snow blower's oil drain plug. The drain plug is on the righthand side bottom of the engine block. Remove the plug by hand by twisting it off to the left, or use a pair of pliers to loosen it if it is too tight. Allow all the old oil to drain out of the engine, then replace the drain plug.

Open the oil fill cap at the middle top of the engine and add 26 ounces of SAE 5W-30 oil.

Remove the spark plug wire. Fit the spark plug wrench over the spark plug and turn it to the left to remove it.

Set your spark plug gap tool to .030 inches and use it to set the gap on your new spark plug.

Screw the new plug in by twisting it to the right until it is tight, then replace your spark plug wire.
