Caterpillar EXCAVATOR PARTS MADE IN CHINA NEW 416F 420F 428F 430F 432F 434F 444F 360-3988 CRANKSHAFT MAIN BEARING SPARKLING MACHINERY
SPARKLING MACHINERY NEW 416F 420F 428F 430F 432F 434F 444F 360-3988 Crankshaft Main Bearing is a critical engine load-bearing and lubrication component for Caterpillar 416F, 420F, 428F, 430F, 432F, 434F, and 444F excavators (widely used in construction, mining, and municipal infrastructure projects). As the "crankshaft stability anchor", it supports the crankshaft’s rotational motion, reduces friction between the crankshaft and engine block, and absorbs radial loads from power transmission—ensuring smooth engine operation during high-intensity tasks like digging, heavy lifting, and rock breaking, while protecting core engine parts from wear.
Meeting Caterpillar OEM standards (part no. 360-3988), it endures -30°C to 150°C engine temperatures, resists oil oxidation and metal fatigue, and maintains consistent lubrication performance. Strict testing guarantees seamless compatibility with the seven Caterpillar models and long-term engine reliability.
Your Caterpillar excavator’s crankshaft protection solution starts here.
Now, we’re proud to present the CATERPILLAR EXCAVATOR PARTS MADE IN CHINA NEW 416F 420F 428F 430F 432F 434F 444F 360-3988 CRANKSHAFT MAIN BEARING by SPARKLING MACHINERY. Next, we’ll cover its core strengths: seamless compatibility with seven Caterpillar models, reliable load-bearing performance, rigorous quality, and more—helping you understand how it extends your equipment’s engine lifespan and cuts maintenance troubles.

And first—thank you so sincerely, from the bottom of our hearts, for choosing SPARKLING MACHINERY’s 360-3988 Crankshaft Main Bearing for your Caterpillar 416F, 420F, 428F, 430F, 432F, 434F, or 444F excavator! Your trust isn’t just a purchase to us; it’s the driving force behind our commitment to meeting Caterpillar’s strict standards for engine bearing components.
This crankshaft main bearing isn’t just a spare part—it’s your excavator engine’s "rotational stabilizer"; a faulty one can cause crankshaft misalignment, abnormal noise, or even catastrophic engine failure. Ours is engineered to fit and perform exactly like Caterpillar’s original, so you can count on it fully. Let’s dive into why it’s the perfect match for your machine.
Why choose the SPARKLING NEW 416F 420F 428F 430F 432F 434F 444F 360-3988 Crankshaft Main Bearing?
- Direct-fit compatibility: Exclusively tailored to match the exact inner diameter, outer diameter, and width specifications of Caterpillar 416F/420F/428F/430F/432F/434F/444F engine crankshaft journals and block bores. Marked with genuine part number 360-3988, it aligns perfectly with existing crankshafts and engine blocks—no machining, resizing, or adapter use is needed. This cuts replacement downtime by up to 30%, getting your Caterpillar excavator back to on-site work faster.
- Precision control: Features ultra-accurate dimensional tolerance (deviation <0.01mm for key surfaces) and optimized oil groove design (matching Caterpillar’s original lubrication flow parameters), ensuring uniform oil film coverage and stable load distribution. It maintains crankshaft stability—e.g., supporting 444F’s heavy-load mining operations or 416F’s urban construction tasks—preventing friction-induced wear and power loss.
- Rigorous quality: Undergoes 18+ strict quality tests tailored to Caterpillar excavator engine conditions, including 600MPa radial load-bearing trials (no deformation or cracking), high-temperature oil compatibility tests (-30°C to 150°C, 700+ cycles), wear resistance checks (no excessive wear after 15,000 hours of use), and fatigue durability trials (250,000+ cycles of simulated operation without failure). It withstands high-temperature engine environments, dusty construction sites, and continuous mechanical loads without performance degradation.
- Professional support: Backed by a dedicated technical team with deep expertise in Caterpillar 416F/420F/428F/430F/432F/434F/444F engine systems and crankshaft main bearing maintenance. We offer 7×24 online assistance, including step-by-step installation guides (with model-specific bearing clearance charts, mounting torque values, and lubrication pre-fill tips), maintenance recommendations (e.g., periodic oil analysis, bearing wear inspection), and troubleshooting for issues like engine knock, excessive oil pressure fluctuation, or bearing seizure. Our team ensures an average response time of <2 hours.
- Cost-effective reliability: Delivers Caterpillar OEM-level performance at a competitive price, avoiding the premium of original dealer parts for crankshaft main bearings. Its durable construction (high-strength multi-layered metal material, anti-wear and anti-corrosion coating) extends service life by up to 45% compared to generic alternatives, reducing long-term replacement costs by 30%. It also minimizes unplanned downtime caused by bearing failure—preventing costly engine overhauls and delays in construction or mining projects.
