Parts for Mtd 170-CU: Cu Crankcase Parts

Piston ring set for small engines. Installs between cylinder wall and piston to maintain gas compression. Replace if rings are worn or damaged.

Pistons are essential for proper engine function. When expanding gases push the piston, it turns the crankshaft. When the piston compressed the fuel-air mixture, the spark ignites and causes combustion. If the pistons are going bad, owners might notice white or gray exhaust smoke, low power when accelerating, loss of performance, or excessive oil consumption.Pistons may need to be replaced for any number of reasons. They could have damage to their crown, which could be caused by overheating. There could be impaction marks if they were not installed correctly or if the valve timing is incorrect. The pistons could be fused or have elements that have melted, or there could be cracks in the piston. Any of these issues would necessitate a replacement.This piston is used for select small engines from MTD, Troy-Bilt, Yard Machines, Columbia, and Cub Cadet. Each piston is sold individually and is a genuine OEM part sourced from the manufacturer. Those who need to replace more than one piston will need to buy them separately.

This is a crankcase gasket that seals the crankcase cover to the engine block on a lawn mower. It prevents oil from leaking out of the engine and keeps contaminants from entering the crankcase. Replace this gasket if you notice oil pooling beneath the engine, visible oil seepage around the crankcase cover, or if the gasket is torn or deteriorated.

This crankcase cover kit is a genuine OEM part sourced directly from the manufacturer; it is used to service or replace the crankcase cover in snowblower and log splitter engines and other small engines. The crankcase cover provides an added layer of protection to the crankcase and crankshaft. This cover keeps the elements, dirt and debris from reaching the crankcase. During regular use, normal wear and tear, along with the elements, can deteriorate the plastic and cause damage to the cover. Damage to the crankcase cover will not cause immediate engine issues, but the damage will leave the door open for damage to the crankcase and possibly even the crankshaft. Replacing a damaged cover is much less expensive than replacing a crankshaft.This crankcase cover kit contains everything needed to replace the cover. The crankcase cover, crankcase cover gasket, O-rings, oil plug, and oil seal are in the kit. A socket wrench is needed to remove the crankcase cover. Remove the fuel from the fuel tank. Take the spark plug out and only perform this project when the engine is cool.This crankcase cover service kit is sold as one individual kit. It is compatible with small engines manufactured by MTD, Cub Cadet, Yard Machines, and Troy-Bilt.

Oil fill plug assembly for small engines. Seals the oil fill opening to prevent leaks. Replace if cracked, stripped, or missing to maintain proper seal.

Replacement oil drain plug for small engines on outdoor power equipment. Needed when original plug is stripped, cracked, or leaking. Installs at oil pan.

This replacement part is an oil seal. This is a genuine replacement part made by MTD. This part is used to ensure that oil and other fuel cannot escape from the tank. The seal prevents it from leaking during use to ensure the engine is able to run properly. A new oil seal might be needed if the current one has been damaged.

These gaskets provide protection from outside elements that could interfere with engine performance, such as rain or debris. These gaskets also keep fluids and air from leaking out of the engine, which can reduce engine performance as well. Engine gaskets should be inspected and maintained to ensure proper engine performance. The gaskets are made of materials intended to withstand high heat, like silicone, cork, rubber, or paper, depending on where it is installed. Over time, the gaskets may become worn, cracked, or torn and need to be replaced. A screwdriver is required to remove the engine cover to access the various gaskets.
