Honda 13352-890-300 Balancer Gear (38T)

The Honda 13352-890-300 Balancer Gear (38T) is a genuine OEM component designed for Honda E3500, E4500, EB4000, EM4000, EMS4000, EMS4500, ES3500, ES4500, EV4000, and EW170 generators and welder generators, as well as the GV400 vertical shaft engine. As a direct Honda OEM replacement, this gear is manufactured to the same specifications as the original, ensuring it meshes correctly within the balance shaft assembly without adjustment or modification. Check the serial number on your unit against the fitment table to confirm this is the right part for your specific production run, as Honda periodically updates components at serial breaks.

Key Features

• Genuine Honda OEM Quality — manufactured to Honda's original tooth-count and gear geometry specifications, so the 38-tooth profile engages the balance shaft drive without play or misalignment that would introduce vibration
• Exact-Count Replacement — the 38T designation is the critical spec: swapping in a gear with a different tooth count alters the balance shaft timing and undermines smooth engine operation, making part-number verification essential
• Broad Generator Fitment — fits the E3500, E4500, EB4000, EM4000, EMS4000, EMS4500, ES3500, ES4500, EV4000, and EW170 generators and welder generators, as well as the GV400 vertical shaft engine
• Serial Number Verification Recommended — Honda supersedes internal components at production breaks; always cross-reference your machine's serial number with the fitment table before ordering

The balancer gear is part of the engine's balance shaft system, which counteracts the reciprocating forces produced by the piston and crankshaft during each combustion cycle. By spinning in precise timing with the crankshaft, the balance shaft reduces the vibration that would otherwise be felt through the frame of the generator or the equipment the engine powers. When this gear wears, chips, or loses a tooth, the balance shaft falls out of phase and the engine develops a rough, shaking idle that stresses the frame, fasteners, and internal components over time. Restoring the correct gear returns the engine to smooth operation and prevents the secondary damage that persistent vibration can cause.
