Knowledge

Use this knowledge center to identify construction machinery parts, verify fitment before ordering, and prepare the information needed for an accurate parts inquiry. The guides focus on practical evidence: part numbers, casting numbers, machine model plates, serial numbers, dimensions, and clear photos.

Start with the information you have

• You have a stamped or printed number: read Casting Number vs. Part Number to determine whether the marking is suitable for a catalogue search.
• You only have photos: follow How to Identify an Excavator Part from Photos and capture the views, dimensions, connectors, mounting points, and visible markings that help distinguish similar parts.
• You need to choose a supply type: compare the practical differences in Genuine, OEM, Aftermarket, and Remanufactured Parts.
• You are ready to order: use the parts fitment checklist before confirming quantity and delivery requirements.

Verify fitment before requesting a quotation

A part name alone is rarely enough to confirm compatibility. Two components may look similar while using different dimensions, splines, connectors, pressure settings, or mounting patterns. Prepare as many of the following details as possible:

1. Machine manufacturer, model, and complete serial number.
2. Part number and every secondary number visible on the old component.
3. Clear overall photos plus close-ups of labels, cast marks, connectors, and mounting points.
4. Key dimensions and, when relevant, tooth count, spline count, thread size, voltage, or connector pin count.
5. Required quantity, destination country, and preferred delivery schedule.

If a number cannot be confirmed, send the machine information and photos together rather than relying on appearance alone. This gives the parts team enough evidence to check available references and identify any information still missing.

Browse by brand or parts system

For brand-specific browsing, start with Komatsu parts or Shantui parts. You can also browse common systems such as electrical parts and filter parts. Each hub connects related products so you can compare part numbers and applications within a narrower equipment context.

What to send with a parts inquiry

Include the machine model and serial number, requested part number, quantity, destination, and your contact details. Attach original-resolution photos when identification is uncertain. Do not crop out labels or surrounding mounting features; those details may be necessary to separate visually similar variants.

Request a quote from Danch Machinery with the available evidence. If the information is incomplete, the team can tell you which additional photo, dimension, or machine detail is needed before fitment can be assessed.
