Why the Same Connecting Rod 115026330 Number Ships in Multiple Variants

Superseded part numbers and variant suffixes exist because Shibaura updated the N844 block casting and crankshaft journal dimensions across production runs.

When I worked on Shibaura N844 engines in a Shandong workshop, I encountered connecting rods that looked identical on the bench but had big-end bore differences that would damage the crankshaft if forced together. The base number 115026330 appears across multiple machine generations, yet the actual rod dimension or bushing configuration shifted when the engine block was revised. Ordering by number alone without confirming your engine serial range means you may receive a rod that physically enters the bore but fails under load within weeks.

This connecting rod for New Holland TC35D and L220 applications is verified at the serial level so the variant you receive matches the crankshaft journal and piston pin diameter your engine actually has.

Serial-Range Verification Across the N844 Family

The Shibaura N844, N844L, and N844LT-C engines share a common 2.2L displacement but differ in internal clearances and component weights. A connecting rod for an N844LT-C turbocharged unit may carry different balance specifications than one for a naturally aspirated N844. We confirm fitment by engine tag photograph or serial number, matching the specific rod variant — whether referenced as SBA115026330, SBA115026330C, or SBA115026330R — to your exact build. This eliminates the trial-and-error approach that costs workshops a second teardown when the first rod does not seat correctly.

Interface and Dimensional Cross-Check

Before confirming an order, the critical mating surfaces are verified against your service manual. The big-end bore is checked to the ±0.005 mm tolerance range, the small-end sintered bronze bushing inner diameter is matched to your piston pin specification, and the center-to-center length is confirmed so piston-to-valve clearance remains within design limits. [NEED_CITE: connecting rod big-end bore and crankshaft journal clearance standards] When a worn nameplate leaves you with only a machine model like TC35D or L175, these dimensional checks against known serial-range data provide the same certainty as reading a clear part number off the old rod.

Forged Material and Bore Tolerance in Practice

The 4340 alloy steel forging provides the tensile strength needed for sustained high-load applications — loader cycles, continuous PTO work, and tillage operations place repeated tensile and compressive loads on the rod beam. The big-end bore tolerance directly controls the oil film thickness between the rod bearing and crankshaft journal; too tight and the bearing starves, too loose and impact loading accelerates wear on both surfaces. The sintered bronze small-end bushing retains oil within its porous structure, maintaining lubrication at the piston pin during the brief moments when hydrodynamic film breaks down at top dead center.

What Happens When the Wrong Variant Gets Installed

A connecting rod with an incorrect big-end bore will either crush the bearing shell during torque-up or allow the rod to shift laterally on the crankshaft journal. Both paths lead to the same outcome: metal contamination in the oil, scored journal surfaces, and an engine teardown that now requires crankshaft regrinding on top of the original rod replacement. In a workshop setting, this means the machine that was supposed to be back in service by Monday sits disassembled for another week while a crankshaft is sent out for machining.

Why Source This Connecting Rod Through Our Operation

Our own production lines and qualified sourcing partners operate under the same QC protocol and warranty terms, so whether your connecting rod comes from our facility or a partner line, dimensional inspection standards are identical. We carry eight equipment categories under one account, meaning if your overhaul list also calls for piston sets, seal kits, or gasket sets, the entire job ships as one consignment. Minimum order is one piece — no need to wait until you have a fleet-sized requirement. Our technical team confirms compatibility from a part number, machine model, photograph, or nameplate image, and we cross-reference superseded numbers like 87763364 and P115026330 to ensure the correct variant ships. A sample unit is available for physical fitment verification on your engine before you commit to a bulk order.

Documentation & Verification

• Commercial invoice listing each rod with its verified cross-reference number and engine serial match
• Dimensional inspection record covering big-end bore, small-end bushing ID, and center-to-center length
• Compatibility sheet noting which superseded numbers apply to your specific machine build (reference only)
• Warranty terms covering manufacturing defects for 3–12 months from delivery
• Packing photographs showing rod condition and protective wrapping before crate closure
• HS code and export documentation prepared for your customs clearance process

Fitment Check Before Installation

• Measure big-end bore and compare against your crankshaft journal diameter and service manual clearance spec
• Verify small-end bushing inner diameter matches your piston pin before pressing the piston assembly together
• Check center-to-center length against the old rod to confirm piston-to-valve clearance is preserved
• Inspect rod bolt thread condition and replace fasteners if stretch marks or thread galling are visible
• Perform a trial assembly without rings to confirm free rotation on the crankshaft before final installation
• If any dimension falls outside service manual tolerance, stop and request a replacement before proceeding

Request a Fitment Confirmation

Send your machine model, engine serial number, or a photograph of the engine identification tag so we can verify which connecting rod variant matches your specific Shibaura N844 build. If the nameplate is worn or painted over, a photo of the old rod alongside a measurement of the big-end bore and center-to-center length is usually enough to confirm the correct cross-reference.

Frequently Asked Questions

Q: How do I confirm this connecting rod fits my TC35D when the nameplate is unreadable? A: Provide your engine serial number from the block stamping or send a photo of the old rod with visible casting marks. We cross-reference the serial against Shibaura production records to identify whether your engine uses the N844, N844L, or N844LT-C variant, then match the correct rod dimensions to your specific build.

Q: Multiple part numbers like 115026330, SBA115026330, and 87763364 appear for my machine — which is correct? A: These are superseded and alternate references (reference only) that map to the same base connecting rod, but the variant suffix matters. Send your machine serial or engine tag photo, and we confirm which specific number applies to your production year and engine build so you receive the dimensionally correct rod.

Q: What is the difference between SBA115026330C and SBA115026330R, and which fits my engine? A: The suffix indicates a production revision that may involve bushing configuration, weight balance, or bore tolerance changes. We verify which revision your engine serial requires by checking against factory service documentation, ensuring the rod you receive matches your crankshaft and piston pin specifications exactly.

Q: Can I get a sample connecting rod for physical fitment check before ordering for my fleet? A: Yes, we supply a sample unit so you can measure bore dimensions, verify bushing fit, and perform a trial assembly on one engine. Once you confirm the rod seats correctly and all mating clearances check out, we proceed with the fleet quantity under the same verified specifications.

Q: I only have the machine model with no readable part number — can you still confirm fitment? A: Machine model alone is often sufficient when combined with approximate production year. We reference known serial ranges for that model to identify the engine variant and corresponding rod specifications, then verify with a photo of any visible casting marks on the existing rod if available.
