Parts for Briggs & Stratton 49E877-0004-G1: Cylinder Head, Rocker Arm Cover, Intake Manifold Parts

Here is a metal cylinder head screw replacement that is compatible with a wide range of engines. The screw is typically used as a means to fasten various components together in the engine. This includes securing the cylinder head components. However, it could be used for other applications in some machines. Owners can check their diagrams to see how and where the screws are used. The cylinder head screws are subject to the usual wear and tear, as well as corrosion. When the threads are stripped, they begin to corrode, become bent, or are otherwise damaged, they should be replaced. Replacing the screws tends to be a fast and simple repair. This genuine OEM cylinder head screw is made from high-quality durable metal. It is sold individually, so buyers may want to purchase several at the same time. The screw can be used in a range of machines including lawn mowers, snowblowers, leaf blowers, wood chippers, generators, tillers, pressure washers, and other small engines. Brands with compatible models include Briggs & Stratton, Toro, Cub Cadet, Murray, Lawn-Boy, Simplicity, and MasterCut.

A keeper valve is a small piece of hardware used to help to secure a valve. It is designed for use with pieces of outdoor lawn and garden power equipment that have small engines, a lawn mower, a snowblower, and a wood chipper. It is compatible with products by brands such as Briggs & Stratton, Craftsman, Toro, Cub Cadet, Lawn Boy, MTD, and Simplicity.The keeper valve fits into a groove in the end of the valve stem to secure the valve spring, valve spring retaining washer, and valve stem together. It is only natural that, over time, the keeper valve may wear out from regular exposure to the elements, get damaged, fall out, or become lost. In any of these events, a replacement will become necessary.The replacement or repair process of the keeper valve should be straightforward, but the user replacing the part should always be sure to wear gloves during any assembly, replacement, or installation processes. The user should also refer to the owner's manual of their equipment and any guiding diagrams that clarify the placement location. This keeper valve is an original OEM part sourced directly from the manufacturer, Midwest Engine. It is sold individually.

This is a durable metal valve tappet that is designed for use in small motor lawn equipment. It is attached to the push rod. The valve tappet takes the rotating motion from the camshaft and turns it into a linear motion for the valves to operate correctly. In some cases, the valve tappet can become damaged or break and will need to be replaced.If there is an issue with the valve tappet, a set of pliers will be needed to make the replacement. For safety, use work gloves and make sure the spark plug wire is disconnected before starting the replacement. The crankcase breather, muffler, and other components will need to be taken off to gain access to the valve tappet to replace it.This valve tappet is a genuine OEM replacement component directly sourced from the manufacturer. It is sold as an individual replacement part. It is designed to be used on lawnmowers, snowblowers, tillers, pressure washers, leaf blowers, generators, and chipper shredders manufactured by Briggs & Stratton, Toro, Cub Cadet, Lawn-Boy, Snapper, MTD, and Simplicity.

The spark plug helps to start the engine by creating the spark that will cause the fuel to ignite in the engine during combustions. Over time, the spark plugs will become worn down and go bad. Multimeters are typically used to test the spark plugs. However, owners should also regularly look at the spark plugs to search for signs of corrosion that could indicate they are going to go bad. If they are not functioning properly, the engine will not fire and start. They will need to be replaced. This is an OEM replacement part that can be used on a range of small engines and lawn equipment from many brands. Compatible brands include Toro, Briggs & Stratton, Craftsman, Cub Cadet, Simplicity, and Snapper.

This replacement valve seal is a genuine OEM part for a lawn tractor or mower. The valve stem is a type of valve that transfers oil into the cylinder and then immediately reseals due to the pressure in the chamber. However, if the seal is damaged, it will not close and oil will leak into the cylinder. If this happens, the cylinder head may become overly lubricated and not run well. This seal helps prevent that from happening. It fastens to the intake valve and valve stem keeper. Seals will naturally wear out over time due to stress and exposure to corrosive oxidizing agents in an engine. When this happens, the valve will leak oil. To test if the valve seal is compromised, look for whitish-grey smoke that indicates burning oil and also measure to see how much oil the engine is consuming. If the seal is breached, use a screwdriver and socket wrench set to change out the part. This top of the line replacement valve seal is compatible with Briggs & Stratton, Toro, and Lawn Boy lawn tractors. It is sourced from the original manufacturer and ships individually.

Flange screws have a flange located near the top of the screw, which helps to distribute the connection force over a larger area to reduce potential damage to the machine. It also allows the screws to be used in oversized or irregular holes, and it helps to ensure they stay in place. This flange screw also has a hex top. Screws can last for a long time. However, they may become corroded or worn over time and need to be replaced. They could also become lost and need a replacement. Without all of the screws in the proper places in a machine, it could vibrate too much, which could render it less effective or unsafe to use. The flange screw is a genuine OEM part that can be used with many types of machines including lawn mowers, snowblowers, tillers, pressure washers, leaf blowers, generators, wood chippers, and other small engines. The screws are compatible with Briggs & Stratton, Craftsman, Toro, Cub Cadet, Murray, Lawn-Boy, Snapper, Simplicity, and MTD.

This is the rocker cover gasket, which seals the cylinder head on small engines so that the engine doesn’t develop leaks. Periodically, a gasket may deteriorate with heavy use. To maintain good engine performance, the rocker cover gasket needs to be replaced with an OEM certified replacement. This type of gasket is most often found on lawn tractors. Replacing the original gasket with the new one is a simple and straightforward process. There are four bolts holding the valve cover in place. Simply remove them and the old gasket, which will likely have to be scraped to get it completely off the cylinder head. Place the new gasket exactly over the metal frame of the cylinder head—it should fit perfectly. Hold it in place with a small amount of RTV, a silicon sealer that is impermeable to oil and gasoline. Replace and tighten the four valve cover bolts. This part is made by Genuine Midwest Engine. This part is used in Briggs & Stratton engines and also used by Toro and Vanguard. This is an OEM part. It's also sold individually.

This pushrod serves a vital part of the camshaft in a lawn tractor’s engine. As the camshaft spins, the pushrods open the engine valves to intake air and release the exhaust. Without a functioning push rod, the engine cannot run properly. There are two push rods in an engine made of steel and aluminum, respectively. This item is the longer, 6in steel rod. Be sure to replace the correct part. Pushrods should last for 200,000 miles of wear and tear but can be broken by harsh use. The pushrod needs replacing when the engine starts misfiring or will not run at full power. The most common problem is a bent pushrod. This part is a genuine OEM replacement part straight from the manufacturer. This item is made by Briggs & Stratton, though Toro and Vanguard both make identical parts. Again, this is the steel variety of pushrod, and it is sold individually. Aluminum pushrods are sold separately.

This pushrod is a metal rod that is used in overhead valve engines. It transfers the motion of the camshaft within the engine block to the valves within the cylinder head. One end of the rod is fitted with a lifter that contacts the camshaft. Rods can slip or wear with time and may even break or bend. The pushrod is used within the exhaust valve, and it may become stuck or damaged and require replacement. However, it is not always the rod that is the root of the problem. Malfunctioning valves or bad fuel can be behind bent or broken rods, so a bit of diagnostic work is best done while making the replacement of the rod or associated valves. This is an OEM aluminum push rod replacement designed for use with engines on several Briggs & Stratton, Toro, and other lawn tractor engines. This durably made pushrod sold individually.
