What Arrives Before the Machine Can Move Again

One connecting rod, one piece, shipped the day you confirm.

A mini-excavator sitting idle on a confined trenching site costs more than the part itself every single hour it waits. I have watched a repair shop lose a full weekend because a supplier quoted a batch-production lead time on a single rod for a Yanmar 3TNE78. The crew had the engine torn down, the crankshaft measured, and new bearings staged — then sat on their hands for five days waiting on one connecting rod. That idle window is where deadline penalties start stacking. [NEED_CITE: equipment downtime cost impact on small excavation contractors]

When you send us a photo of a worn nameplate or a machine serial plate, we cross-check the fitment before you pay. No guessing, no trial fitment on the shop floor.

Guangzhou Warehouse Availability and Single-Piece Orders

Our Guangzhou warehouse stocks the Connecting Rod 719810-23100 for immediate pull-and-pack. There is no minimum batch requirement. A workshop supervisor calling at midday can have the rod on an express courier by evening, which matters when a Komatsu PC27R-8 is the only machine available for a Monday pour. We treat a one-piece emergency order with the same dispatch priority as a pallet load.

How Fast Each Shipping Option Actually Reaches You

Express courier delivery typically lands within a few working days for most international destinations, which suits a machine already down on site. Air freight covers medium-distance routes with transit measured in days rather than weeks. Sea freight is the cost-effective choice for stock replenishment but does not solve an immediate shutdown. We quote the estimated arrival window alongside each freight option at the point of order confirmation so you can match the shipping method to the urgency of the repair.

Forged 42CrMo Steel and Shot-Peened Beam Surface

The rod body is forged from 42CrMo alloy steel, a material grade chosen for its fatigue strength under the alternating tensile and compressive loads inside a compact diesel engine. Shot peening the beam surface introduces compressive residual stress, which resists crack initiation at the stress-concentration points near the bolt boss. The rust-inhibiting oil coating protects the machined surfaces during storage and transit, so the rod arrives in installable condition without extra cleaning steps.

The Cost of Ordering the Wrong Rod on a Rush Job

Sending back a misidentified connecting rod means the engine stays apart while you wait for the replacement to arrive. On a compact excavator, the teardown alone consumes a full shift, and a second teardown doubles the labor cost without moving the machine any closer to running. I have seen a 3TNE78A sit for an extra week because someone ordered from a cross-reference table that mixed up the 3TNE78 and 3TNE78A rod variants. We verify fitment against your machine serial number before the box leaves the warehouse. [NEED_CITE: aftermarket cross-reference errors in small diesel engine parts]

Why Buyers Source This Rod Through XUNPO

Our Guangzhou warehouse holds this connecting rod ready to ship, so you are not waiting on a production run. One-piece minimum order means a single emergency repair does not force you into surplus inventory. Part identification from a worn nameplate photo, a machine model, or an unreadable part number keeps the right rod moving toward you. Cross-reference verification covers superseded and alternate numbers so older machines in the Komatsu 3D78 and 3D82 series get the correct variant. Our technical team confirms fitment and grade before dispatch, and sample supply is available when you need a physical check before committing to a fleet order.

Frequently Asked Questions

Q: Is this connecting rod in stock and how fast can it ship? A: The 719810-23100 is held in our Guangzhou warehouse for immediate dispatch. Once payment clears, we pull, inspect, and pack the same day. Express courier options are quoted with an estimated arrival window at the time of order, so you know exactly when the rod will reach your workshop or jobsite.

Q: Can I order just one connecting rod for an emergency repair? A: Yes. Our minimum order is one piece. A single rod for a machine-down situation ships with the same priority as a bulk order. There is no batch-production wait and no requirement to buy surplus inventory you do not need.

Q: My nameplate is worn — how do I confirm the right part number? A: Send us a photo of the nameplate, the machine serial plate, or the old rod itself. We cross-check the fitment against our database covering Yanmar 3TNE78, 3TNE78A, and the full Komatsu 3D78 and 3D82 range. We confirm the correct variant before you pay.

Q: What are the delivery timeframes for express versus sea freight? A: Express courier reaches most international destinations within a few working days. Air freight transit is measured in days for regional routes. Sea freight is the economical option for planned restocking and takes considerably longer. We quote each option with an estimated arrival at order confirmation.

Q: What happens if the part arrives and does not fit? A: Our warranty covers manufacturing defects for 3–12 months. If a fitment issue arises despite our pre-ship verification, contact us immediately with photos of the part and the machine nameplate. We work to resolve the situation through replacement or correct-part exchange as quickly as logistics allow.
