Screw
Genuine Midwest Engine part
By: Midwest Engine
Part Number: 690837

This is a replacement screw that can be used on various types of lawn and garden equipment. The type of equipment will affect where the screw is used on the tool. A screw is used to attach various components together so nothing comes loose while the tool is in use. It can also be used with a nut. It's best to choose a nut that has the same finish and threading as the screw.A screw can be damaged in many ways. If this occurs, it will need to be replaced. Corrosion, wear and tear, extreme stress, and high temperatures can all cause a screw to fail. Inspecting the screw can indicate whether it will need to be replaced. Use a screwdriver to take off the old screw, or use a pair of pliers if the screw has become stripped. Replace it with a new screw.This is an authentic OEM replacement part sourced directly from the manufacturer. Each screw is sold individually. The component is designed for use with lawn mowers, snowblowers, tillers, pressure washers, leaf blowers, edgers, chainsaws, generators, and wood chippers manufactured by Briggs & Stratton, Simplicity, Toro, MTD, Cub Cadet, Lawn-Boy, Homelite, and Murray.

Generic Friction Spring
Genuine Midwest Engine part
By: Midwest Engine
Part Number: 691855

This replacement friction spring is a genuine OEM part meant for any number of small appliance engines run using a starter rope. This spring absorbs large amounts of kinetic energy that could damage the starter rope pulley system. It helps keep the pulley from being overstretched, which would create enough pressure to break the entire system. This spring sits at the center of the pulley system and creates resistance as the user yanks the starter rope. Friction springs can become worn out after repeated use, especially if a user tends to yank the starter rope quite forcefully. The most obvious sign of a worn of friction spring is if the pulley system lacks any resistance. As the user pulls the cord, they should feel a little pull back, but if the friction spring is worn, there will be much less resistance. Replacing this part is straightforward and will only require a screwdriver. Simply open the pulley system, carefully remove the old spring, and install the new one. This part is compatible with a wide number of appliances from Toro, Vanguard, Briggs & Stratton, and Lawnboy. It comes sourced from the original manufacturer and ships individually.
