Parts for Craftsman 917986331: Mower Deck Parts

This no grease mandrel assembly is the part that houses the shaft where the mower blade attaches. It is mounted to the deck of the mower by three bolts, which are sold separately. The mounting holes on the mandrel housing are not threaded, but the bolts used to secure the mandrel to the deck are self-tapping. If the lawnmower is no longer providing an even cut, there may be a problem with the mandrel assembly. A broken or damaged mandrel assembly can severely reduce the mower's cutting performance. Replace it as soon as possible. The mandrel shaft goes through the deck, and the pulleys are attached to them, then the belt that drives the mandrels is placed in the pulleys. A spacer must be installed under the pulley. Failing to use a spacer or installing it on top of the pulley will result in damage to the shaft and pulley. This mandrel assembly is compatible with Ariens, Craftsman, Husqvarna, Poulan, and Weed Eater lawn mower models. It is an OEM part sourced directly from the manufacturer and is sold individually. The mandrel assembly includes a housing, shaft assembly, bearing, and nut only; the pulley/washer and blade bolt/washers are not included.

This is the replacement washer head screw for a lawnmower or lawn tractor. It is black in color and is roughly 1.5 inches in length. With its hexagonal head and washer face, it is usually used as a fastener in outdoor power tools. It is self-tapping, meaning it can tap its own threads when screwed into either plastic, wood, or metal. When used with lawn tractors and lawnmowers, this screw is commonly employed for securing the mandrel housing to the mower deck. Replace the washer head screw if the old screw is damaged or missing. First, a pilot hole should be made that's slightly smaller than the diameter of this screw before driving it with a screwdriver. This is also a thread-forming type of self-tapping screw, and it does not have a pointed tip. It is compatible with specific products from major brands like Ariens, Craftsman, Husqvarna, Murray, Poulan, Ryobi, and Weed Eater. This part is sold individually and is a genuine OEM part sourced directly from the manufacturer.
