Q1: What is the product identification and applicable scope of the 16863-2303-0/16863-23013 crankshaft for Kubota D722 engines?
A1: The 16863-2303-0 and 16863-23013 crankshafts are OEM-compatible core power transmission components, exclusively engineered for Kubota D722 3-cylinder air-cooled diesel engines (0.72L displacement, 10HP/7.5kW @ 3600rpm)—a compact, high-efficiency engine widely used in small-scale machinery.
Core Product Details
- Part Number Differentiation:
- 16863-2303-0: Standard OEM replacement crankshaft for regular-duty D722 engines, optimized for stable operation in light-load scenarios;
- 16863-23013: Reinforced high-strength variant, featuring thicker journal walls and enhanced heat treatment for high-load D722 applications.
- Product Structure: Integrates crankshaft journals (main journals + connecting rod journals), crank throws, counterweights, and front/rear seal mounting surfaces—delivered as a finished precision-machined component with no additional processing required.
- Applicable Machinery & Working Scenarios:
- Small construction equipment: Kubota KX41-3 mini excavators, Bobcat S70 skid-steer loaders (garden landscaping, small foundation digging);
- Power equipment: Portable generators, water pumps (backup power supply, agricultural irrigation);
- Agricultural machinery: Compact tractors, lawn mowers (small farmland tilling, turf maintenance).
- Core Application Scenarios: Direct replacement for worn/broken original crankshafts (e.g., journal wear, crank throw bending, fatigue cracking) and engine overhaul projects, restoring the D722 engine’s power transmission efficiency and operational stability.
