Description
Overview:
The Key B 3/16" SQ x 2 1/4" is a square-section drive key for Viking ride-on mowers, manufactured by Stihl for reliable OEM fit and performance. This genuine metal key locks a pulley, gear or hub securely to its shaft to transmit torque and prevent slipping. It is commonly used across the drive train and cutter deck assemblies on models such as the MR 4082.0 K and MR 4082.0. Dimensions are 3/16 inch square by 2 1/4 inch long (approximately 4.76 mm square by 57.15 mm long), matching the original size for the keyway. Genuine Stihl Part, MPN 9471 435 1622, supplied to restore correct operation after loss or wear.
