This is a bushing made from black plastic with a cleft down the middle to provide enough flex for easy insertion. It has a flanged design, which means it won’t easily pop out after installation, even under stress from constant vibration. The bushing’s primary purpose is to protect wires and cables from damage as they pass through a channel. As such, the material is fairly durable and does not need to be replaced under ordinary circumstances. That said, there are some situations in which it can become damaged. For one thing, it’s easy to damage while repairing the wires or cables that run through the bushing. If the bushing does need to be replaced, it requires disconnecting any cables or wires that run through the bushing. Pop out the old bushing with a rubber mallet, install the new bushing the same way, reconnect the wires, and the repair is complete. This is an OEM part sourced directly from MTD, and it is sold individually. It was initially used on snowblowers but has also been used on lawnmowers and lawn tractors.

This replacement part is a short block. It is a genuine replacement part made by MTD. A short block is a part that is found inside the engine. It comprises a portion of the cylinder block below the head gasket but above the oil pan. This helps the engine run smoothly overall as well as start and stop the engine efficiently. A new short block might be needed if the user notices that the current one is damaged in any way including being bent, dented, cracked, or chipped. If the user hears unusual noises coming from inside the machine it is possible that the short block is malfunctioning. This can be due to normal wear and tear over time. If this is the case it is recommended that the user replace this part immediately. This is a genuine OEM replacement part. This short block is sold individually and is sourced directly from the manufacturer.
