Komatsu Boom Pins & Bushings
Komatsu Boom Pins & Bushings is a supported WQC Parts hub because it already connects buyers to real collection paths. Use this page to narrow from the broad Komatsu model or system into listed products, serial-aware collections, or specific component groups.
For the best result, start with the exact model and serial number, then choose the closest series, workgroup, product group, or part number shown below. Do not rely on description alone when a serial break, attachment arrangement, arm length, bucket linkage, or hydraulic configuration may change the correct part.
Before Ordering: Confirm the Machine and Serial Range
Boom Pins & Bushings parts can change by series, serial number break, regional arrangement, attachment package, and installed component group. Use this hub to narrow the path, but confirm the final part number against the machine serial number, parts book reference, or existing part stamping before ordering.
- Best information to provide: machine model, serial number, current part number, component location, and a photo if available.
- For pins, bushings, service kits, pumps, hydraulic parts, and engine components, similar descriptions may still represent different parts.
- When you are unsure, use the quote path instead of guessing from a broad description.
Need help confirming a Komatsu part? Contact WQC Parts
Komatsu Boom Pins & Bushings are focused on boom foot, boom nose, boom cylinder, and related upper-structure pivot areas. These are high-wear components where fitment depends on the exact part number, serial range, machine configuration, and diagram position.
Pins and bushings may appear simple, but small dimensional differences can affect installation, clearance, service life, and damage to mating components. A bushing that is close but not correct can wear the bore, damage the pin, or shorten the life of the repair.
If you do not see the exact item listed here, send us the Komatsu part number, machine model, serial number, or parts book reference and we will help confirm the correct WQC Parts option.
How to Identify the Correct Pin or Bushing
- Start with the original Komatsu part number when available.
- Confirm the machine model, series, and serial range.
- Check the diagram callout and part location: boom, arm, bucket, bucket link, blade, bellcrank, or cylinder pivot.
- Verify quantity, length, diameter, flange style, lubrication path, and any notes in the parts book.

Replacement Planning
For best repair results, inspect the full wear area rather than replacing only the most obvious part. Pins, bushings, seals, collars, links, and hardware often wear together. If the bore or linkage is damaged, replacing only one component may not restore proper fit.
Fitment and Serial-Range Guidance
Komatsu part fitment should always be confirmed against the machine model, serial range, installed arrangement, and the original part number. Many Komatsu machines share similar component descriptions across different series, but a small difference in serial range, arm length, linkage arrangement, hydraulic configuration, or engine arrangement can change the correct replacement part.
- Use the part number on the old component whenever it is available.
- Check the machine model and serial range before ordering.
- Confirm diagram position, quantity, and notes when parts-book information is available.
- For pins, bushings, seals, hydraulic parts, and engine components, verify the exact component group before assuming interchange.
Why Buy Komatsu Parts from WQC Parts?
WQC Parts is built around heavy equipment part-number lookup, aftermarket sourcing, and practical fitment support. Our Komatsu hub structure is designed to help buyers move from broad machine research to the correct product collection, then down to the exact part number whenever possible.
- Aftermarket Komatsu replacement parts organized by machine family, system, and part number.
- Support for alternate part numbers, dashed and non-dashed part number searches, and model-family navigation.
- Structured hubs for common wear areas such as pins, bushings, seals, hydraulic components, filters, pumps, and engine parts.
- Clear fitment reminders to reduce ordering mistakes and avoid unnecessary downtime.
Frequently Asked Questions
Should pins and bushings be replaced together?
Often yes, especially in high-wear linkage locations. Inspect both components and the surrounding bore before deciding.
Why are diagram positions important?
The same machine can have several pins or bushings with similar descriptions but different dimensions and quantities.
Can I order by measurement only?
Measurements help, but the safest method is to confirm the part number, serial range, and diagram position.
