Caterpillar EXCAVATOR PARTS MADE IN CHINA NEW 312D2 312E 313D2 360-3986 CONNECTING ROD BEARING SPARKLING MACHINERY
SPARKLING MACHINERY NEW 312D2 312E 313D2 360-3986 Connecting Rod Bearing is a critical engine lubrication and load-bearing component for Caterpillar 312D2, 312E, and 313D2 excavators (widely used in construction, municipal engineering, and medium-scale mining). As the "engine motion buffer", it reduces friction between the connecting rod and crankshaft, while absorbing impact loads from piston reciprocation—ensuring smooth power transmission during tasks like digging, lifting, and material handling, and protecting the engine’s core moving parts from wear.
Meeting Caterpillar OEM standards (part no. 360-3986), it endures -30°C to 150°C engine temperatures, resists oil oxidation and metal fatigue, and maintains stable lubrication performance. Strict testing guarantees seamless compatibility with the three Caterpillar models and long-term engine operational reliability.
Your Caterpillar excavator’s engine wear protection starts here.
Now, we’re proud to present the CATERPILLAR EXCAVATOR PARTS MADE IN CHINA NEW 312D2 312E 313D2 360-3986 CONNECTING ROD BEARING by SPARKLING MACHINERY. Next, we’ll cover its core strengths: seamless compatibility with three Caterpillar models, reliable friction reduction, 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 360-3986 Connecting Rod Bearing for your Caterpillar 312D2, 312E, or 313D2 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 connecting rod bearing isn’t just a spare part—it’s your excavator engine’s "wear shield"; a faulty one can cause metal-to-metal contact, crankshaft damage, or even complete 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 312D2 312E 313D2 360-3986 Connecting Rod Bearing?
- Direct-fit compatibility: Exclusively tailored to match the exact inner diameter, outer diameter, and thickness specifications of Caterpillar 312D2/312E/313D2 engine connecting rod journals. Marked with genuine part number 360-3986, it aligns perfectly with existing connecting rods and crankshafts—no resizing, grinding, or adapter use is needed. This cuts replacement downtime by up to 25%, 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 distribution. It minimizes friction—e.g., protecting 313D2’s crankshaft during heavy mining or 312D2’s connecting rod during urban construction—preventing abnormal wear and maintaining smooth engine operation.
- Rigorous quality: Undergoes 18+ strict quality tests tailored to Caterpillar excavator engine conditions, including 500MPa load-bearing trials (no deformation), high-temperature oil compatibility tests (-30°C to 150°C, 700+ cycles), wear resistance checks (no excessive wear after 12,000 hours of use), and fatigue durability trials (200,000+ cycles of simulated impact without cracking). 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 312D2/312E/313D2 engine systems and connecting rod bearing maintenance. We offer 7×24 online assistance, including step-by-step installation guides (with model-specific bearing clearance charts and lubrication pre-fill tips), maintenance recommendations (e.g., periodic oil analysis, bearing wear inspection), and troubleshooting for issues like engine knock, excessive oil consumption, 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 connecting rod bearings. Its durable construction (high-strength bimetallic material, anti-wear coating) extends service life by up to 40% compared to generic alternatives, reducing long-term replacement costs by 25%. It also minimizes unplanned downtime caused by bearing failure—preventing costly engine overhauls and delays in construction or mining projects.
