I recommend selecting a Hyundai R130 bucket pin and bushing kit by comparing the machine’s measured dimensions, bucket linkage configuration, and wear condition—not by relying on the model name alone. A suitable kit normally includes the replacement bucket pins and matching bushings required for one defined repair position, while seals, washers, retainers, or shims may be included only when specified in the supplier’s quotation. At Zhonghai Jiuchuan, I help buyers confirm the correct configuration from drawings, part references, and measurements before production or shipment.

This guide explains what to verify, what a kit may contain, how to replace worn components, and how to reduce the risk of ordering incompatible parts. It is intended for excavator owners, maintenance teams, dealers, and construction-equipment distributors sourcing Hyundai R130 bucket pin and bushing components.
The bucket pin connects the bucket or linkage components, while the bushing provides a replaceable bearing surface between moving parts. During excavation, digging forces create repeated rotation, impact, and abrasive contamination around these joints. Replacing the worn pin and bushing together can restore the intended fit more effectively than installing only one new component against a severely worn mating part.
The correct kit may be used at the bucket-to-link connection, bucket-to-arm connection, or another defined linkage position, depending on the specific Hyundai R130 configuration. These positions are not automatically interchangeable because their diameters, lengths, retaining methods, and lubrication arrangements can differ. For that reason, I treat the location of the repair as a primary compatibility factor.
A “bucket pin and bushing kit” does not have one universal contents list across all suppliers. A standard quotation may include one or more pins and their matching bushings, while an expanded repair package may also contain seals, thrust washers, locking components, or shims. Buyers should ask for a line-by-line packing list rather than assuming that every wear component is included.
| Component | Purpose | What to confirm |
|---|---|---|
| Bucket pin | Connects the linkage or bucket joint | Diameter, working length, shoulder, groove, and retention design |
| Bushing | Provides the replaceable bearing surface | Inside diameter, outside diameter, width, material, and oil passage |
| Seal or dust ring | Helps limit entry of dirt and loss of lubricant | Whether it is included and matched to the joint |
| Washer, shim, or retainer | Controls axial position or secures the assembly | Quantity, thickness, and installation position |
The Hyundai R130 designation is an important starting point, but it may not be sufficient for a safe parts match. Different production periods, linkage arrangements, bucket designs, or previous repairs can result in different dimensions. I therefore recommend providing the machine model, serial number or serial range when available, the exact joint location, and photographs of the existing components.
Do not assume that a pin removed from a worn joint represents the original size. Wear can reduce the pin diameter, enlarge the bushing bore, or create an oval shape. If the replacement is copied from a damaged component without checking the housing and linkage, the new parts may still have excessive clearance.
Before ordering, measure the old pin and the bushing housing where practical, and inspect both sides of the joint. Record the pin diameter, effective working length, bushing outside diameter, bushing inside diameter, and bushing width in millimeters. As an illustrative record only, a drawing might show values such as an 80 mm pin diameter, a 95 mm bushing outside diameter, and a 100 mm bushing width; these numbers are examples, not stated Hyundai R130 specifications.
For better purchasing accuracy, record measurements to 0.1 mm when the available measuring tools and component condition allow it. Compare the measurements with the supplier’s dimensional drawing, not only with a product photograph. The drawing should also identify chamfers, grease holes, grooves, shoulders, retaining features, and any required installation orientation.
Bucket pins are commonly supplied in wear-resistant steel grades selected for load-bearing and impact applications. The relevant specification may include material grade, heat-treatment method, surface hardness, straightness, and machining tolerance. I do not recommend accepting a general statement such as “high quality steel” without asking which characteristics are controlled and recorded.
Depending on the design, a pin may have a smooth working surface, a grease passage, a retaining groove, or a stepped profile. These details affect installation and service performance. A replacement pin should match the original functional design unless the supplier has reviewed and approved an alternative configuration.
Bushings may be produced from different steel-based or composite bearing materials, depending on the load, lubrication method, and customer requirement. The most important factors are the bushing’s dimensional accuracy, surface finish, hardness or material specification, and compatibility with the pin and housing. Material selection should be based on the actual joint conditions rather than choosing the lowest quoted price.
Grease-hole location is also important. A bushing with an incorrectly positioned lubrication passage may restrict grease delivery or interfere with the existing grease system. I ask buyers to provide a drawing or clear photographs of the grease-hole position when the replacement bushing is not identical to a standard catalog design.

First, identify the joint that requires repair and decide whether the work includes only the pin and bushing or also seals, washers, shims, and related linkage components. Inspect the surrounding bore for scoring, cracks, distortion, or excessive ovality. If the housing itself is damaged, a new bushing alone may not correct the alignment problem.
Use suitable lifting, supporting, and extraction equipment for the bucket and linkage assembly. After removal, clean the bore and inspect the removed pin and bushing separately because wear patterns can reveal misalignment or insufficient lubrication. Keep the old parts available until the replacement dimensions and kit contents have been verified.
Before pressing in a bushing, compare the new components with the approved drawing and purchase order. Check the number of parts, dimensions, grease-hole orientation, chamfers, retaining features, and packaging labels. If any measurement or feature differs from the agreed specification, stop installation and request clarification from the supplier.
Clean the housing and use an appropriate installation method that protects the bore and bushing. Align the lubrication passage and install seals, washers, and retainers in their specified positions. After fitting the pin, lubricate the joint according to the equipment maintenance instructions and check for smooth movement, correct axial position, and abnormal play.
The most common risk is treating “Hyundai R130” as a complete dimensional specification. The same excavator model name can be associated with different attachments, linkage positions, or production variations. A purchase request that includes the exact joint location and available dimensions gives the supplier a stronger basis for confirmation.
A new pin cannot compensate for a distorted or excessively worn housing. If the bushing seat is damaged, the repair may require line boring, machining, or an engineered oversize solution. I recommend asking a qualified maintenance technician to assess the bore before finalizing a standard-size kit.
Some suppliers quote a pin-and-bushing set only, while others quote a complete joint repair kit. Differences in contents can affect both price comparison and installation planning. Request the exact quantity and specification of every included item in writing.
A reliable supplier should be able to discuss dimensions, materials, machining features, lubrication design, packaging, and inspection documentation. I also recommend checking whether the supplier can provide a drawing for approval before production. This step is especially useful when the available sample is worn or when the buyer is sourcing for multiple machines.
Pricing depends on dimensions, material, machining complexity, quantity, packaging, and whether additional components are included. Minimum order quantity and lead time should be confirmed before purchase because they can vary by standard item, custom item, and production schedule. I advise buyers to compare quotations on the same contents and specification basis rather than comparing unit prices alone.
At Zhonghai Jiuchuan, I support B2B buyers who need Hyundai R130 bucket pin and bushing solutions for maintenance, distribution, or equipment repair. My approach is to review the machine information, repair position, drawings, photographs, and measurements before confirming a production specification. This helps separate a genuine dimensional match from a generic part described only by excavator model.
We can discuss individual pins, matched pin-and-bushing sets, or broader joint repair requirements, subject to the confirmed drawing and order scope. For repeat purchasing, I can also help organize consistent specifications, packing identification, and documentation for future inquiries. Any material, tolerance, inspection, MOQ, and lead-time commitment should be confirmed in the formal quotation before production.
The best Hyundai R130 bucket pin and bushing kit is the one that matches the actual joint position, measured dimensions, lubrication design, and condition of the surrounding housing. A careful replacement process starts with inspection and dimensional confirmation, then continues with drawing review, complete kit verification, and correct installation. This method reduces the risk of receiving parts that fit the model description but fail to fit the machine.
To request a quotation from Zhonghai Jiuchuan, prepare the Hyundai R130 model and serial information, the bucket or linkage position, photos of the old components, available measurements in millimeters, required quantity, and whether seals or hardware are needed. I can then review the information and help define the appropriate pin and bushing kit for your application. Please request a formal specification and packing list before placing the order.
