Genuine Mtd part
By: Mtd
Part Number: 753-04814

This is a cylinder assembly that is designed for use in various lawn and garden small engines. The cylinder assembly is a component of the starter assembly and engine. Problems with engine compression are usually the result of the cylinder assembly going bad and needing to be replaced. If the cylinder assembly is not working, the engine may not work at all. One test of the cylinder assembly is to cover the cylinder hole with a finger and pull the starter rope.

The engine will need to be taken apart to get access to this assembly so that it can be removed and replaced. This repair requires work gloves and a basic toolset. Never work on hot engines and make sure the spark plug is removed before working on the machine.This cylinder is an authentic OEM replacement part that is directly sourced from the manufacturer.

#8-16 X .75 Screws
Genuine Mtd part
By: Mtd
Part Number: 791-181345

Few parts fulfill as many roles on lawn mowers and other landscaping power tools than the cover screw. This screw serves to attach metal housing parts, assemblies, and shrouds to one another on equipment such as power vacuums, snow blowers, edgers, tillers, hedge trimmers, lawn tractors, leaf blowers, grass trimmers and cultivators. As these are extremely durable metal screws, they seldom fail under ordinary use. It should be noted, however, that they are most often used at connection and pressure points. Stresses at these junctions sometime loosen screws, causing them to be lost or occasionally resulting in stripped threads. It's also occasionally the case that these screws are lost during repair or routine maintenance of yard equipment because of their small size. Users should make sure to consult their owner's manuals for replacement steps and any special instructions. Because of their small size and the ease of losing them during repair work or maintenance, it's recommended to keep a supply of appropriately sized screws on hand. Most importantly, when replacing a part make sure to use a genuine OEM replacement part. They are manufactured according to the specs of the original parts and are perfect replicas.
