5 SHEAR PINS FITS MTD 738-04124A 738-04124 31A-3BAD700 31AS6LEG752

5 Shear Pins for MTD

This set of 5 shear pins is designed for MTD lawn mowers and replaces OEM part numbers 738-04124A, 738-04124, 31A-3BAD700, and 31AS6LEG752; they provide a critical fail-safe that protects the mower's drivetrain from damage when encountering obstacles.

Overview

These shear pins serve as a sacrificial component in MTD mower decks, breaking under excessive load to prevent gearbox or blade spindle damage. Designed for easy replacement, each pin fits into the spindle assembly and shears cleanly when the blade strikes a solid object. This set of 5 ensures you have spares ready for ongoing maintenance.

Good To Know

Q: Can these shear pins be reused after they shear? A: No, shear pins are one-time use; once they break they must be replaced with new pins to maintain proper protection.

Q: What torque specification should I use when installing? A: Always refer to your equipment's manual; typical installation is hand-tight plus a quarter turn using a wrench, but never over-torque as it may prevent the pin from shearing correctly.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
