Hex Bolt
Genuine Mtd part
By: Mtd
Part Number: 710-3180

This hex bolt is a necessary component used in a variety of small to medium sized gasoline powered engines used primarily in yard work, gardening, and landscaping. The primary use of this hex bolt is to secure the idler pulley assembly to the body of the machine. The idler pulley functions to engage the turning mechanism of the yard tool when engaged. The power yard tools that require an idler pulley which would use this screw are tillers, riding mowers, yard tractors, tillers, snow blowers and chippers. Engaging the rotating part of the yard tool places a great deal of resistance on the idler pulley, which may eventually result in it needing to be replaced. When replacing the idler pulley assembly, it's important to remember that the attaching hardware, such as the hex bolt, has also experienced a great deal of wear and should be replaced as well. This hex bolt attaches the idler pulley assembly directly to the machine housing and can be removed with a 9/16 wrench. Make sure when replacing the bolt to use a genuine OEM manufactured part that is identical to the manufacturer's original piece. This bolt is compatible with the following brands: Yard-Man, Bolens, Craftsman, Yard Machines, Troy-Bilt, Cub Cadet, Huskee, Ryobi, Murray, MTD, MasterCut, and Montgomery Wards.

3/8-24 Hex Nut
Genuine Mtd part
By: Mtd
Part Number: 712-0241

This genuine OEM hex nut is manufactured to exact standards and sourced from the manufacturer. It can be used with trimmers and mowers from RYOBI, MTD, Bolens, Troy-Bilt, Yard Machines, Huskee, Yard Man, and Cub Cadet.

Three Arm Knob
Genuine Mtd part
By: Mtd
Part Number: 720-0170

This three arm knob is an authentic OEM replacement part sourced directly from the manufacturer for use on lawn and garden machines as an adjustment handle, often for seat adjustment. The three sides of the knob make it easy to grasp and turn. The long threaded shaft ensures the knob is securely attached to the part it is used to adjust and has ample room for turning and adjusting. Over time, the plastic arms of the knob may deteriorate and crack making it difficult to turn. Cracks in the plastic can cause cuts and scratches. If the plastic breaks completely off, the handle will not be useable and should be replaced. If the plastic is broken, a pair of vise grips will be needed to remove the shaft of the handle. Once the handle is removed, line the threaded end of the handle up with the hole and turn it to tighten it in place. Don't over tighten as it could cause the threads to strip and not be usable.This three arm knob is a black plastic and metal part that is sold individually. It is designed for use in lawn and garden equipment that is manufactured by Husky, Craftsman, and Yard Machines.

Flat Washer
Genuine Mtd part
By: Mtd
Part Number: 736-0262

This flat washer is used to attach the idler pulley in a number of small and medium sized gasoline powered engines. These engines include snow blowers, log splitters, riding mowers, lawn tractors, and chippers. Because the idler pulley is subject to a great deal of resistance when the pulley is engaged, eventually the pulley will wear out. Should there be a squealing sound when engaging the drive, the problem is likely the idler pulley. In these cases, the pulley must be replaced. It is a good idea to replace the surrounding hardware when replacing the idler pulley; tNhis includes the flat washer, which is subject to corrosion during heavy use. To replace the idler pulley, first detach the spark plug cap. If on a mower or tractor, drop the mower deck. Remove the original pulley and install in order: replacement pulley, hex bolt, flat washer, flange nut. Apart from dropping the mower deck, the only tools required to complete this installation may be a 9/16 ratchet and combination wrench. This washer is a genuine OEM replacement part, designed to perfectly replicate the original piece. This washer is compatible with Troy-Bilt, Yard Man, Yard Machines, MTD, and Craftsman devices.
