Parts for Briggs & Stratton 4035A7-0409-E1: Engine Sump, Lubrication Parts

This cylinder head gasket is a genuine replacement part for select small engines. The cylinder head gasket is installed between the cylinder head and the engine block. It is responsible for creating a seal for the internal combustion engine to work properly and to help keep the oil and coolant separate as they travel between the cylinder head and the engine block. Gaskets are considered a maintenance part because their exposure to high heat and pressure cause wear, warping, and other damage over time. When a gasket is damaged, the seal is affected. Air could escape or the oil and coolant could mix, which would both produce bad results for the engine. This genuine OEM cylinder head gasket replacement is manufactured to exact standards by Briggs & Stratton. This part is compatible with select engines found in lawn and garden machines manufactured by Briggs & Stratton and Toro. The gasket is sold as an individual part and does not include any hardware or additional components. Be sure to allow the engine to cool and wear gloves when replacing gaskets. It is a good idea to replace gaskets when performing other engine repairs to ensure a proper seal when putting the engine back together.

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 boot is a rubber piece that is responsible for connecting the spark plug to the spark plug wires and completing the connection. Spark plugs are necessary to create the engine spark that will start the motor in lawn equipment and other small engines. The boot holds the terminal and keeps everything protected from the elements and insulated so that it continues to work correctly. If the spark plug connection seems weak or if the existing boot is damaged, this replacement could provide the solution. This durable rubber boot will insulate the spark plugs and help any small engine run better. This spark plug boot replacement can be used with a number of Briggs & Stratton engines and is compatible with hundreds of different machines from Toro, Lawn-Boy, and Briggs & Stratton. This boot replacement is sold individually as a single piece and does not include the terminal or any other housing or materials.

This replacement part is a nut. This part is small but important in various types of equipment. Nuts are able to work with other small parts such as washers and screws to secure equipment components in place.If a nut has become stripped or worn down over time, it is possible that it can no longer perform the function needed. Be sure to wear work gloves when working with small parts such as nuts to prevent injury during the repair. This is a genuine OEM replacement part manufactured by Midwest Engine. This part is sold individually.

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.

This replacement exhaust gasket is a certified genuine OEM part for a lawn tractor engine. This gasket helps to seal off the exhaust from the carburetor. For an engine to run, it must first mix fuel with air to prepare the fuel for combustion. By sealing off the exhaust, this gasket allows for fresh air to enter into the carburetor from outside the engine rather than from the exhaust. Gaskets often degrade over time due to the stress of pressure and heat. If the exhaust gasket breaks its seal, it can affect the engine's overall performance. Be on the lookout for an especially noisy engine that doesn't provide as much power and is less fuel efficient. There may also be a noticeable burning smell coming from the engine. To replace the exhaust gasket, use a socket wrench and wrench set to remove the air filter and blower housings, then remove the exhaust manifold and switch out the gasket. This replacement exhaust gasket is compatible with engines made by Toro, Briggs & Stratton, Murray, Snapper, and Simplicity. It comes sourced directly from its original manufacturer and does not include any additional hardware.

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.
