The Multiquip 1626163820 Ring Gear is a genuine OEM component designed for BLW-400SSW, KD1800, KD1800KD6, and KD6 series equipment. As a direct Multiquip OEM part, it is manufactured to the same specifications as the original, ensuring correct mesh, tooth profile, and dimensional fit. This ring gear ships as an exact match to the factory-installed component, so there is no guesswork when ordering a replacement. Verify your model code against the fitment list — BLW-400SSW, KD1800, KD1800KD6, and KD6 — before ordering to confirm compatibility.
Key Features
- Correct Tooth Geometry — Manufactured to OEM tooth profile and pitch specifications, ensuring proper gear mesh and smooth power transmission without premature wear.
- Direct Drop-In Replacement — Engineered to the same dimensional standards as the original ring gear, allowing straightforward installation without custom fitting or machining.
- Broad Fitment Coverage — Compatible with BLW-400SSW welders and KD1800, KD1800KD6, and KD6 core drills, making it a versatile stock item for multi-machine fleets.
- Sustained Drive Performance — A worn or damaged ring gear causes slippage, irregular engagement, and loss of drive output; replacing it restores full rotational power transfer to the drivetrain.
- Genuine Multiquip OEM Quality — Sourced directly through the Multiquip OEM supply chain, this part meets the material hardness and load-bearing requirements for the ring gear position in the drivetrain assembly.
A ring gear is a large-diameter toothed component that meshes with a smaller drive gear or pinion to transfer rotational force through the drivetrain. In equipment like core drills and welders, the ring gear plays a central role in converting engine or motor output into the working speed required at the business end of the machine. When a ring gear becomes worn, chipped, or cracked, the result is rough engagement, loss of torque transfer, or complete drivetrain failure — making timely replacement critical to keeping the equipment functional and safe to operate.
