This small spacer fits on the idler assembly shaft to properly space and align the belt tensioner. Replacing a worn spacer helps keep the drive belt tracking correctly so the drum/tub runs smoothly and quietly. What it does:

• Spaces and centers the idler pulley on its shaft
• Helps maintain proper belt alignment and tension
• Can reduce squeaking or chirping from the idler area
• A worn or missing spacer may let the belt ride off, fray, or stop the drum/tub

• 1 idler spacer

• Disconnect power before servicing; let hot components cool
• Access the idler assembly per your model, relieve belt tension, and remove retaining hardware to slide off the pulley and old spacer
• Install the new spacer in the same location/orientation; reassemble and route the belt correctly
• Rotate the drum/tub by hand to verify smooth belt tracking before restoring power

A flange nut's unique wide flange design distributes the nut's pressure over the part it is securing. In return, it creates an even fastening surface, which reduces part damage and nut loosening. This one-piece all-metal fastener has a lock nut version that features a protruding circular flange. This drastically increases bearing surface, compatibility either for irregular or oversized holes, and surface tension reduction. Flange lock nuts are the preferred type of fastener for many lawnmower models because it can provide better fastening than regular screws, which are known to loosen under extreme vibration. However, it’s important to know that flange lock nuts are susceptible to wear and tear due to constant vibration exposure. It is essential to replace the broken flange lock nut immediately to prevent serious damage to the lawnmower. The MTD 712-04063 Flange Lock Nut OEM replacement can be used with Craftsman, White Outdoor, Yard Machines, MTD, or Columbia lawnmowers. It is a genuine or OEM MTD replacement part that measures 5/16-18. It is threaded and requires the use of a wrench. This replacement flange lock nut is sold individually. An MTD bolt carriage may also be needed and is sold separately.

This replacement screw secures appliance panels and components. With a #10-16 thread and 0.75-inch length, it replaces stripped, rusted, or missing hardware to restore a tight, rattle-free fit and reduce vibration and noise.

• Fastens cabinet panels, brackets, or internal parts in washers and dryers
• Direct replacement for worn or lost screws to keep assemblies aligned and secure
• Helps address loose/vibrating panels, rattling noises, or visible gaps/misalignment
• Spec: #10-16 thread; 0.75-inch length

• Disconnect power; for washers, also shut off water supply
• Match the original screw location; start threads by hand to prevent cross-threading
• Use a driver that fits the screw head properly; tighten snugly without overtightening

This is a flanged lock nut. It’s designed to apply tension, typically on a joint that needs to have a certain amount of flex. As such, it’s mostly used on snowblower chutes and lawnmower handles. They can remain in place, but with a forgiving connection that can take a beating. The nut size is 3/8, with a thread size of 16. A lock nut will generally last for many years. However, the silicone ring inside will wear down if it’s frequently tightened and loosened. It needs to be replaced when it will no longer reliably remain in place. Generally, this begins as a symptom of slight slippage and worsens as time goes on. Thankfully, whether it’s being used on a snowblower or a lawnmower, this nut is generally straightforward to access. Simply unscrew the old nut, then screw the new nut on until it’s nice and tight. Our flanged lock nuts are genuine OEM MTD nuts, and they are sold individually.

This steering gear is an integral part of the guidance mechanism for riding mowers and lawn tractors. This gear meshes with the turning mechanism of the wheels, connecting the front axle to the steering column. The constant, short diameter turning of riding mowers puts a tremendous amount of pressure on the steering pinion gear as well as the steering plate, causing the teeth of each of these parts to wear out. Over time, the steering will become less responsive until eventually the drive wheels will not respond at all when the steering wheel is turned. This is usually an indication that the steering pinion gear is stripped and must be replaced. Replacing this gear involves removing the nut and bolt that fix the gear to the mowing housing. Often, the bushing that sits beneath the pinion gear also needs to be replaced because of wear, and this is the best time to do that, as well. It's also a good idea to see if the steering plate teeth are also worn, as this is the ideal time to replace it as well. All parts should be replaced with genuine OEM parts, manufactured, as this replacement part is, according the specs of the original part. This pinion gear is compatible with Huskee, Murray, Bolens, Yard Man, Troy-Bilt, MTD, Yard Machine, and Cub Cadet riding mowers. This part sold individually.

A replacement bracket screw used to fasten internal brackets and panels to the appliance frame, restoring secure mounting and reducing rattling or misalignment caused by stripped, corroded, or missing fasteners. What it does

• Secures mounting brackets, panels or trim to the appliance chassis.

This heater baffle mounts near the heating element to deflect and distribute radiant heat. It helps protect nearby surfaces and wiring while promoting more even temperatures and reliable performance inside the appliance.

• Directs and diffuses heat from the element to reduce hot spots
• Acts as a heat shield to protect the liner and adjacent components from direct radiant heat
• Helps maintain proper clearance and airflow around the element
• Damage or a missing baffle can lead to uneven temperatures, localized discoloration/scorching, or a burning smell

• Disconnect power at the breaker or unplug the appliance; allow it to cool completely
• Access the heater area; remove the screws or clips securing the existing baffle and retain the hardware
• Position the new baffle in the same orientation; ensure it does not contact the heating element
• Restore power and test operation

The nut-hex flange 5/8-18 features a hex nut with a wide flanged portion at one end. This flange will act as an integrated washer that does not spin. Since the flange acts as a washer, it ensures that the nut can fasten to the material's surface evenly. If any of these nuts are removed from a machine to do other work, it is recommended to replace them with a new nut-hex flange. Check the nuts that are currently on the machine at least once a year. Make sure they are properly tightened and that they are in good condition. Replace them as needed. This OEM part will work for many types of equipment, including lawnmowers, edgers, snowblowers, and lawn tractors. The part will work with many brands, including Ryobi, Poulan, Bolens, Yard-Man, MTD, Yard Machines, and Troy-Bilt.

This is a genuine replacement bolt that is designed specifically for use on select lawn tractors. This tractor bolt is a specialty piece of hardware designed for use on the steering segment gear. This screw holds the gear in place and is exposed to constant vibrations and repetitive motion as a result. Over time, that can result in damage, wear, or even total breakage of the bolt and require a replacement. If the bolt isn't functional or is missing, the steering segment gear will not be secured and that can lead to further damage if left unattended. Using a genuine replacement part like this will guarantee an exact fit for compatible models. This genuine OEM gear bolt is manufactured by MTD. It is compatible with lawn and garden equipment from RYOBI, HUSKEE, Troy-Bilt, Bolens, Yard Machines, Yard Man, and Cub Cadet, along with select models from MTD. The bolt works for more than 100 compatible models. It is made of durable metal and sold as an individual unit. A wrench or socket will be required to replace this part. Always wear gloves when performing repairs on lawn and garden equipment and allow the engine to cool before doing any work.
