Parts for Briggs & Stratton 100602-0100-E1: Cam Gear, Crankcase Cover / Sump, Crankshaft, Cylinder, Cylinder Head, Piston / Rings / Connecting Rod Parts

This is a genuine OEM bushing/seal kit that is manufactured for use on a selection of Briggs and Stratton engines found on outdoor power equipment. The seal and bushing are responsible for providing a sealed connection within the engine. They are exposed to constant vibrations, pressure, and high temperatures, which can cause them to wear down over time. Seals can also become brittle and damaged with age, resulting in the need for replacement. It's best to purchase the kit and replace both parts at once with this OEM set from Briggs and Stratton. This OEM seal and bushing kit is manufactured for use in Briggs and Stratton engines found in snow throwers, lawn mowers, and leaf blower/vacuum models produced by the brand. It is also compatible with select models from Toro. The bushing and seal are sold as a kit, which includes one seal and one metal bushing. No other hardware or accessories are included. Any other needed hardware will require an additional purchase. It is important to wear gloves when performing repairs on outdoor equipment and make sure that the right tools are used for the job.

Seals between crankcase and crankshaft to prevent oil leaks and contamination. Replace if you notice oil pooling or engine performance issues.

Lower oil seal prevents engine oil leaks in small lawn and garden engines. Replace if you notice oil pooling or reduced performance. Verify fit with your engine model number.

Engine won't restart after hitting an object? A sheared flywheel key is often the cause. This small part keeps the flywheel connected to the crankshaft.

Fix engine knocking or loss of power with this piston pin lock. Secures the piston pin in small engines. Essential for proper piston assembly.

Replace a worn, damaged, or missing piston pin in your engine. This small pin connects the piston to the connecting rod and requires replacement when bent or broken.

This screw is a genuine Midwest Engine replacement part for small engine appliances, including lawn tractors, lawn mowers, snowblowers, leaf blowers, vacuums, and tillers. The purpose of a screw is to tightly link materials together through rotation that pierces into the material. A screw might have to be replaced in the event that it is lost or misplaced, a common occurrence due to its size. A screw might also be replaced if it deteriorates over time, through erosion, cracking, or piercing, thereby reducing its efficacy in holding materials together. This kind of damage can be attributed to general overuse, to age, or simply to long-term exposure. If a screw is subject to any of this kind of damage, it is best to replace it immediately, as the materials held together by the screw must continue to be held together. Remember to always wear gloves when handling, repairing, and operating outdoor equipment. This screw is compatible with the following brands: Briggs & Stratton, Toro, Cub Cadet, and Lawn Boy.

This is a genuine intake gasket replacement that is designed for use in certain lawn mower engines. This specialty intake gasket is what is responsible for creating the seal between the carburetor and the breather tube so that no gases or fluids leak when they pass between the two. This gasket is subjected to constant high pressure, vibrations, and extreme temperatures, and over time it will need replaced. Gaskets are generally considered a part of routine maintenance on most engines, and many owners will choose to keep a few extra on hand in case of an urgent repair need. This genuine OEM intake gasket is manufactured by Briggs & Stratton and designed to offer an identical replacement for the original gasket that came on the new unit. It is compatible with lawn mower engines in models from Briggs & Stratton and Toro, and will fit on over 150 different engine models in lawn mowers from these brands. The intake gasket is made of durable composite material. It is also a good idea to replace gaskets when servicing the carburetor to ensure a proper seal after reassembly. Be sure to use the right tools to install this part so that it isn't damaged in the process.

Spark plugs work by providing an electric spark in a combustion chamber, igniting the mix of fuel and air that allows the engine to turn and propel a drive shaft. Insulated with ceramic to make sure the electric charge flowing through it is properly discharged, the plug is screwed into the cylinder head. The movement of the piston sucks fuel into the cylinder until it reaches the optimum level, the compression triggering the spark plug to send a pulse that ignites the fuel and pushes the piston to the back of the cylinder. This process is repeated hundreds of times a minute in an internal combustion engine. Eventually spark plugs simply wear out, particularly if they are not properly gapped, if the fuel mixture is improper, or the engine is subject to excessive use. This plug is compatible with most lawnmowers, small engines, and pressure washers made by Briggs & Stratton, Cub Cadet, and Toro. The plug itself is a guaranteed OEM part and is sold individually.

Fix rough or ineffective engine operation with this crankshaft end play shim. Controls axial movement between flywheel and thrust surface for smooth rotation.

Engine won't start or runs rough? A cracked or missing spark plug boot causes misfiring and prevents proper ignition. Easy DIY replacement part.
