To select a Hyundai R130 bucket pin and bushing kit correctly, I recommend confirming the excavator’s exact model, serial range, attachment configuration, and measured pin and bushing dimensions before ordering. The name “Hyundai R130” identifies a machine family, but bucket geometry and production variations can affect fitment. A reliable replacement kit should match the pin diameter, bushing outside diameter, bushing length, working width, retention method, and bucket linkage arrangement. At Zhonghai Jiuchuan, I use these details to help buyers confirm the correct excavator bucket pins and bushings rather than relying on a model name alone.

I prepared this guide for excavator owners, rental companies, repair workshops, fleet managers, dealers, and parts buyers sourcing a Hyundai R130 bucket pin and bushing kit. It is useful when a bucket has excessive movement, when a pin is difficult to remove, or when a maintenance team needs to plan a replacement job. It also supports buyers comparing aftermarket and original-equipment replacement options. Because machine configurations differ, I treat the information here as a selection framework rather than a substitute for dimensional confirmation.
The bucket pin connects the bucket, linkage, and related attachment components through aligned bores. The bushing provides a replaceable wear surface between the pin and the surrounding bore, helping maintain the intended pivot relationship during digging, lifting, and bucket positioning. When the pin and bushing are correctly matched, the load is distributed through the joint instead of being concentrated on a damaged or loose contact area.
Typical replacement points can include the bucket ear joint, linkage connection, and other pivot locations on the attachment. The exact number of components depends on the bucket design and the configuration of the Hyundai R130 machine. For this reason, I do not recommend ordering by a generic “full set” description unless the seller has confirmed the included parts against the buyer’s assembly.
I first ask for the full machine model designation, serial number or production range, and the bucket or quick-coupler arrangement. Two excavators carrying a similar model name may have different attachment dimensions, especially when buckets have been replaced or modified. Photographs of the bucket ears, linkage, pin ends, and retaining hardware can reveal differences that a short model description may not show.
I also recommend identifying whether the bucket is a standard digging bucket, heavy-duty bucket, rock bucket, grading bucket, or another attachment type. Different buckets can use different ear spacing, pin lengths, and bushing arrangements. If the machine uses a quick coupler, the connection geometry must be checked separately from a direct-mounted bucket.
Before removing the old parts, I record the visible pin length, exposed pin diameter, retainer position, and distance between the bucket ears. After disassembly and cleaning, I measure the pin at several points because wear is often uneven. For practical purchasing records, I recommend taking readings at at least 3 positions along the working area and recording dimensions to 0.01 mm when using a suitable precision measuring tool.
| Measurement | Why It Matters | Recommended Record |
|---|---|---|
| Pin outside diameter | Confirms the replacement pin’s working diameter | Measure unworn and worn areas separately |
| Bushing inside diameter | Shows the running clearance with the pin | Measure after cleaning and removal |
| Bushing outside diameter | Confirms the fit inside the bucket or linkage bore | Compare with the housing bore |
| Overall pin length | Ensures correct engagement and retainer position | Include shoulder, groove, and end features |
| Bushing length and flange design | Prevents interference or insufficient support | Check each position separately |
I compare the measurements from both sides of the joint whenever possible. A difference between the left and right sides may indicate uneven wear, a previous repair, or a non-standard attachment. If the bore is visibly oval, cracked, scored, or enlarged, a new bushing alone may not provide a durable repair because the housing may need line boring, welding, or machining by a qualified workshop.
Bucket pins and bushings are commonly selected according to the load, movement, lubrication method, and working environment. Pin design may include a smooth working surface, shoulders, grooves, holes, or retaining features. Bushing design may be plain, flanged, split, or produced for a specific installation arrangement.
I recommend evaluating material and heat-treatment information from the supplier, but I avoid treating a material grade as proof of performance by itself. The correct choice also depends on dimensional accuracy, surface finish, hardness control, lubrication compatibility, and the condition of the mating bore. For abrasive quarry, demolition, forestry, or heavy digging work, buyers should explain the operating conditions so the supplier can recommend a suitable configuration instead of offering a generic replacement.
Common warning signs include increased bucket movement, knocking during operation, visible gaps around the pin, grease loss, difficulty maintaining bucket position, and accelerated wear on one side of the joint. A pin that appears acceptable at its exposed end may be significantly worn inside the bushing. I therefore recommend removing contamination and checking both mating surfaces rather than judging the condition from appearance alone.

There is no universal wear limit that applies to every Hyundai R130 attachment and operating condition. The correct limit should come from the machine or attachment maintenance information, the component drawing, or an engineering assessment of the joint. If those records are unavailable, I advise buyers to provide measurements and photographs to a qualified technician before deciding whether to replace only the pin, only the bushing, or the complete joint assembly.
I begin with the excavator parked on stable ground, the attachment supported, the hydraulic pressure released according to the machine’s maintenance procedure, and the work area isolated. Pins can be heavy and may be under load, so removal should be performed with suitable lifting and extraction equipment. Personal protective equipment and the workshop’s lockout procedures should be followed throughout the job.
After removing the retainer and pin, I clean grease, dirt, rust, and compacted material from the joint. I inspect the pin surface, bushing wall, grease passage, seal area, and bucket ears. I also check whether the bushing has rotated, shifted, cracked, or damaged the surrounding bore.
Before installation, I compare every supplied component with the removed parts and approved measurements. The pin length, diameter, shoulder position, retaining groove, grease hole, and end profile should match the application. I also verify whether the kit includes seals, spacers, thrust washers, retainers, or only the primary pins and bushings.
Installation should follow the correct pressing or driving method for the bushing design. I do not recommend hammering a bushing into a misaligned or damaged bore because this can distort the component and reduce service life. After assembly, the joint should be lubricated with the appropriate grease, checked for free movement, and inspected for abnormal play before the excavator returns to work.
Pricing depends on the number of components, material and treatment requirements, machining complexity, packaging, order quantity, and shipping destination. A buyer requesting a complete kit should list each required position instead of asking for an undefined set. This allows the supplier to quote the correct quantity and reduces the risk of missing retainers or position-specific parts.
Minimum order quantities and lead times vary by standard availability and customization level. Standard-size components may be easier to source, while non-standard dimensions, special drawings, or private-label packaging may require additional production planning. I recommend requesting a drawing confirmation, component list, packing details, and estimated production schedule before placing a purchase order.
At Zhonghai Jiuchuan, I support buyers who need more than a model-name quotation. Our team can review measurements, photos, drawings, and worn samples to help identify the required excavator bucket pins and bushings. We can discuss standard or customized dimensions, component combinations, packaging requirements, and export documentation according to the project.
For an efficient inquiry, I recommend sending the Hyundai R130 model and serial information, attachment type, pin and bushing measurements, required quantity, destination country, and clear photographs. If you have a technical drawing or the removed parts available, include those as well. This information helps us prepare a more precise fitment review and commercial quotation without making unsupported assumptions about the machine configuration.
The safest way to choose a Hyundai R130 bucket pin and bushing kit is to combine model identification with actual dimensional inspection. Confirm the pin diameter and length, bushing dimensions, bore condition, retention method, attachment type, and required component quantity before purchasing. If the housing is damaged or oval, plan for repair work rather than treating a new kit as a complete solution.
My recommended next step is to collect the machine details, measure the joint, photograph the assembly, and send the information to Zhonghai Jiuchuan for review. We can then help you determine whether you need a standard replacement, a position-specific kit, or a customized solution. This process gives B2B buyers a clearer fitment decision and reduces avoidable delays during installation.
