The Multiquip 1629223490 Crankshaft Metal is a genuine OEM component designed for KD1800, KD1800KD6, KD6, and HTH44T series equipment. As a direct OEM replacement, this part is sourced and specified to meet the original build requirements of your Multiquip machine. Confirmed fitment spans KD1800 and KD6 core drill platforms as well as the HTH44T hydrostatic ride-on trowel, making it a versatile stocking part for fleets running multiple Multiquip product lines. Order with confidence knowing you are installing the exact component your machine was built with.
Key Features
- OEM-Spec Crankshaft Bearing Surface — Manufactured to the original dimensional tolerances that govern journal clearance and rotational precision within the engine assembly.
- Drop-In Engine Fit — Engineered to seat correctly within the crankcase of compatible Multiquip engines without additional machining or shimming.
- Broad Multiquip Fitment — Compatible with KD1800, KD1800KD6, KD6, and HTH44T models, covering both core drill and hydrostatic ride-on trowel applications.
- Sustained Power Delivery — A properly fitted crankshaft metal maintains the oil film that protects rotating journals; worn bearings cause rapid journal damage, power loss, and eventual engine seizure.
- Genuine Multiquip Part — Supplied as genuine OEM stock under part number 1629223490, ensuring material grade and geometry match the original engine specification exactly.
Crankshaft metals — also known as crankshaft bearing shells — are precision inserts that line the main bearing bores in the engine block and the big-end bores in the connecting rod. They create a thin, pressurized oil film between the rotating crankshaft journals and the stationary or moving housing surfaces, absorbing load while preventing metal-to-metal contact. When these bearing metals wear thin, oil pressure drops, clearances increase, and the crankshaft journals are exposed to direct contact — leading to scoring, knocking, and ultimately catastrophic engine failure. Replacing them at the correct service interval, or whenever bearing knock is detected, is one of the most cost-effective ways to protect a high-hours engine.
