Connecting Rod 115026330 for Shibaura N844 – OE Interchange

Verified Cross-Reference — Superseded Shibaura and New Holland part numbers resolved to a single aftermarket connecting rod fitment

Technical Specifications

Application Suitability

When the Manual Shows One Number but the Engine Needs Another

The same base connecting rod appears under at least six OEM reference numbers across the Shibaura N844 family and New Holland equipment range.

I have seen workshops pull a rod stamped SBA115026330C from a TC35D engine, order what the old parts book lists, and receive a component that physically fits but sits with a slight offset in the crankshaft journal. The issue is not the number itself but the superseded revisions behind it. Shibaura updated the N844 series through multiple production runs, and New Holland carried those changes into tractors, loaders, and mowers without always updating their service documentation in lockstep [NEED_CITE: OEM part number supersession tracking for agricultural and compact construction engines]. A Connecting Rod for Shibaura N844 / New Holland cross reference fitment demands more than a catalog lookup — it requires matching the engine serial to the specific rod revision that left the assembly line.

Engine Variants and Serial Range Coverage

The N844 platform expanded into the N844L and N844LT-C variants, each introducing changes to internal clearances and component dimensions. This Connecting Rod for Shibaura N844 / New Holland cross reference fitment covers all three engine designations, but the correct application depends on confirming which variant sits in your machine. A New Holland BOOMER 3040 might carry an N844L while a BOOMER 4055 runs the N844LT-C, and the connecting rod journal interface differs between them.

Cross-Reference Resolution Across Discontinued Numbers

Part numbers 87763364, SBA115026330R, and P115026330 all point to the same connecting rod assembly in different manufacturer catalogs and time periods. We resolve these superseded and alternate references to a single verified aftermarket part, eliminating the guesswork when your old rod carries a number that no longer appears in current listings [NEED_CITE: aftermarket cross-reference verification practices for superseded engine components].

Key Dimensions Before Installation

Before fitting, the piston pin bore, big-end bore, and center-to-center length must be checked against the removed component. These interfaces determine whether the Connecting Rod for Shibaura N844 / New Holland cross reference fitment seats correctly in your specific engine build. Previous crankshaft regrinds or bearing shell replacements can shift the required dimensions, making a direct measurement essential rather than optional.

Decoding Specifications for Real-World Fitment

The connecting rod transmits combustion force from piston to crankshaft, and its dimensional accuracy directly affects engine balance and bearing life. The big-end bore must match the crankshaft journal diameter within the specified clearance range; any deviation causes oil film breakdown and accelerated bearing wear. The piston pin bore interface must maintain concentricity with the big-end to prevent the piston from rocking in the cylinder liner. Machined alignment tolerances on the rod cap and beam ensure the assembly stays true under the high-torque loading conditions typical of agricultural tilling and front-end loader operation. The ISO-standard quality inspection covers these critical dimensions before dispatch, so what arrives matches the engine rebuild specification rather than a generic catalog entry.

What Happens When Fitment Is Assumed Rather Than Confirmed

A connecting rod that bolts in but does not match the engine variant creates problems that surface weeks later. Slight bore misalignment leads to uneven bearing wear, which progresses to knocking under load and eventually spun bearings. For a New Holland TC40D working daily in landscaping or a BOOMER 50D under heavy hauling, that delayed failure means pulling the engine again — a second teardown, a second set of gaskets and seals, and another stretch of unplanned downtime [NEED_CITE: engine bearing failure progression in compact diesel engines under cyclic loading]. The cost of verification before installation is measured in minutes; the cost of skipping it is measured in days.

Why Source This Rod Here

Our selected production lines and qualified sourced supply carry the same QC and warranty terms, so the connecting rod you receive is inspected to the same standard regardless of origin facility. We cover eight product categories under one account, meaning if your engine rebuild also requires seal kits, piston sets, or crankshaft bearings, everything ships as one consignment. The minimum order is one piece — useful when a single rod failed and the rest of the engine checks out. Our technical team verifies compatibility against your machine model, engine serial, or even a photograph of the old part and its stampings. Cross-reference verification covers the superseded numbers like 87763364 and SBA115026330C that older service manuals still list. A sample connecting rod is available for fitment trial before you commit to a bulk order across a mixed-brand fleet.

Documentation & Verification

• Commercial invoice listing all cross-reference numbers (115026330, SBA115026330, 87763364) for customs clarity
• Part compatibility sheet confirming your specific N844 variant and New Holland machine serial
• Dimensional inspection record covering piston pin bore, big-end bore, and center-to-center length
• Warranty terms document specifying coverage period against manufacturing defects
• Packing photographs showing rod condition and protective wrapping before crate closure
• HS code and customs documentation support for international agricultural parts shipments

Fitment Check Before Installation

• Compare big-end bore diameter of the new rod against the removed component and crankshaft journal
• Verify piston pin slides freely through the small-end bore without binding or excessive play
• Check rod cap mating surface for flush alignment with the beam before torquing fasteners
• Confirm oil passage alignment between rod big-end and crankshaft journal feed hole
• Trial-fit one rod in the cylinder before committing the full set to the engine block

Requesting a Fitment Confirmation

Send us your machine model designation, engine serial number, or a clear photograph of the stamping on the old connecting rod. If the nameplate is worn and only the New Holland model (such as TC35DA or BOOMER 3045) is readable, that is sufficient to begin the cross-reference verification. We will confirm which variant of the Connecting Rod for Shibaura N844 / New Holland cross reference fitment matches your exact equipment and advise on any dimension-specific requirements before you place an order.

Frequently Asked Questions

Q: How do I confirm this connecting rod fits my specific New Holland or Shibaura machine when the nameplate is unreadable? A: Provide the engine model stamped on the block (N844, N844L, or N844LT-C) and any visible serial sequence. If only the machine model is legible, such as BOOMER 2035 or TC40DA, our technical team cross-references the factory build records to identify the correct rod variant for your serial range.

Q: The old rod has a different number (SBA115026330 / 87763364 / SBA115026330C) — is 115026330 still the correct replacement? A: Yes. These are superseded or alternate OEM reference numbers that all resolve to the same connecting rod assembly. We verify which revision your engine originally carried and confirm the aftermarket part matches the required dimensions and journal interface.

Q: Why are there multiple part numbers (115026330, SBA115026330, SBA115026330R) listed for what looks like the same rod? A: Shibaura and New Holland updated part numbers across production runs and service bulletin revisions. The R and C suffixes indicate revision levels. All listed numbers cross-reference to this connecting rod, and we confirm the correct application against your engine serial.

Q: I only know my machine model (e.g., TC35D or BOOMER 2035) — can you identify the correct rod without the old part number? A: Yes. Share the machine model and serial number, and we cross-reference the applicable engine build variant. This covers the N844 family differences and ensures the connecting rod matches your specific equipment configuration.

Q: Can I order a sample connecting rod to verify fitment before placing a larger order? A: Sample supply is available. You receive one connecting rod for trial installation, confirming piston pin bore, big-end bore, and overall fitment in your engine before committing to a full-set or fleet-level bulk order.
