Parts for Briggs & Stratton 31E577-0110-E1: Flywheel Parts

This durable plastic ratchet pawl is used on select engines that feature what is known as a Susa starter. In this configuration, the ratchet pawl will be responsible for engaging the recoil starting system. Then, the starting system will allow the engine to fire. Over time, the pawl can become worn or damaged due to regular use. If this happens, the recoil can slip and cause difficulties with starting the engine. If the engine isn’t starting or you can hear it slipping when you try to fire it up, a replacement ratchet pawl could be needed. Be sure to allow the engine to cool before replacing any parts or doing any work and always wear gloves. This replacement is a genuine OEM part that includes two ratchet pawls for various Briggs & Stratton engines on small lawn equipment. This part offers compatibility with over 150 engines from Briggs & Stratton, Toro, Lawn-Boy, and Vanguard by Briggs & Stratton.

This is a replacement screw to secure the pawl friction plate used in many types of lawn and garden equipment. The part is also sometimes called a flange bolt. It is identical to the original screw that came with the machine and will replace a lost or damaged screw. The screws could become damaged due to corrosion or an incident that causes the screw to bend or break. They also serve as replacements in case the screw was lost. Replacing the screw is a simple repair to make. This is an authentic OEM replacement screw that is sold individually. Some buyers might want to have an extra screw on hand. The replacement screw for the pawl friction plate can be used on lawn mowers, snowblowers, tillers, pressure washers, generators, edgers, log splitters, wood chippers, and other small engines. Compatible brands include Briggs & Stratton, Craftsman, Toro, Cub Cadet, Lawn-Boy, Snapper, MTD, and Simplicity.

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.

The flywheel fan is attached to the flywheel and is designed to help circulate air and keep the engine cool during use. This plastic blower fan should run whenever the engine is running to ensure that the equipment doesn’t overheat. The fan may stop working over time due to regular wear or as a result of being damaged. If theflywheel fan isn’t working, the engine could risk overheating, and that could lead to many other issues. Replacing it with this genuine OEM replacement will ensure that the equipment can operate safely and at peak performance. This genuine OEM Flywheel Fan from Briggs & Stratton is designed to fit most lawn equipment engines in the 319000 and 31A000 model families. It is made with exact standards and comes directly from the manufacturer, providing peace of mind that it will always work as it should. This unit is sold individually and contains the flywheel fan and a replacement screen. The bolt required to secure the fan is sold separately.
