Troy-bilt 738-06654 Shear Pin 0.25 X 1.5 Inches

Product Description

The TROY-BILT 738-06654 is a shear pin designed to protect the auger drivetrain on snow throwers and outdoor power equipment. Shear pins are sacrificial fasteners engineered to break under sudden overload, preventing damage to the auger shaft, gearbox, and impeller when the auger strikes a hard obstruction. This pin measures 0.25 inches in diameter and 1.5 inches in length. It is a standard service part installed by power equipment technicians and capable DIYers during routine maintenance or after an auger jam.

This shear pin is used in snow thrower auger assemblies where the drivetrain requires overload protection. It seats through the auger shaft and drive hub, holding the auger in engagement during normal operation. When an obstruction causes excessive torque, the pin shears cleanly to protect the drivetrain. Replacing the shear pin restores the auger to working order quickly. This part is appropriate for residential snow removal equipment in the TROY-BILT product line.

Key Features

• Sacrificial overload protection for auger drivetrains
• Diameter of 0.25 inches and length of 1.5 inches for precise fitment
• Designed to shear cleanly under sudden overload, minimizing drivetrain damage
• Standard replacement service part for TROY-BILT snow equipment
• Straightforward field replacement requiring basic hand tools

Compatibility

Designed as an OEM-style replacement shear pin for TROY-BILT snow thrower auger assemblies requiring a 0.25-inch by 1.5-inch pin.

Installation Notes

Shear pin replacement is performed by power equipment technicians or experienced equipment owners. Always shut off the engine and disconnect the spark plug wire before servicing the auger assembly. Remove the broken pin remnants from the shaft and hub, align the replacement pin through both the shaft and hub bores, and secure it with the retaining clip or cotter pin as specified by the equipment service manual. Never substitute a standard fastener for a shear pin, as doing so eliminates overload protection and may cause serious drivetrain damage.
