Original Manufacturer Approved replacement Mandrell/Jackshaft Housing Assembly used on Lawn Tractors/Mowers. Includes housing, shaft assembly, bearing, and nut. The mounting holes on the Mandrel are not threaded. But the bolts that are used to secure the mandrel to the deck are self tapping. 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.

It was an easy replacement till.....
Love ereplacement parts don't get me wrong but Briggs and stratton smh I'm disappointed the ball bearings inside of the housing were pressed incorrectly! That will cause a problem with the shaft for the blades! This is my 4th one! Briggs and stratton you might get sued on this one! This comment does not affect ereplacement parts and their services! Ereplacement part it would be nice to send me a promo code sometime in the near future!
