Replacement tooth references as Lingfeng lists them; confirm fit and wear life on your bucket with a sample trial.
Lingfeng catalogue bucket teeth
Lingfeng’s page titled E30 is a table of ten tooth references, from E30 to E385. Pick the row that matches your part marking, confirm the adapter and retention parts with Lingfeng, and fix the drawing before you order.
Find your row before you ask for a quote
Copy the reference exactly as printed and quote it with the row.
Lingfeng files this page under its Caterpillar interchange category and titles it E30. The table covers ten type labels, each with a part reference. [1] These are Lingfeng’s own cross-references for finding a tooth. Fit on your bucket and any link to Caterpillar are things to settle with Lingfeng in writing.
| Lingfeng type label | Published part reference |
|---|---|
| E30 | 1U3202 |
| E307 | 6Y3222 |
| E312 | 1U3252 |
| E200B | 1U3302 (9J4302) |
| E320 | 1U3352 |
| E325 | 7T3402 |
| E330 | 9W8452 (1U3452) |
| E345 | 9W8552 (1U3552) |
| E365 | 6I6602 |
| E385 | 4T4702 |
Before ordering: agree the exact Lingfeng item, adapter interface and drawing revision. Some rows carry a second number in brackets, shown here as printed. Ask Lingfeng what each one means.
The page shows one yellow tip, with no scale. It lists no dimension drawing, mass, steel grade, hardness range or service life. Ask Lingfeng for each of these against your chosen row; the type label, photo and machine size will not tell you.
Your machine may carry a replacement bucket or a different tooth system from the one it was sold with. Send the marking on your current tooth and photos of the connection. If the marking has worn off, ask Lingfeng to identify the part from a drawing or a sample.
Match the tip, adapter and retainer together
Three interfaces to agree before a replacement order.
- Identify the adapter nose. Send clear views of the existing nose and the tooth pocket. Ask Lingfeng to name the matching system and send its dimensional drawing. A tip only fits once its adapter is matched too.
- Identify the retention parts. Note the current pin or retainer marking and which way it sits. Ask Lingfeng to name the exact replacement pin and retainer, since tips that look alike can fasten differently.
- Check the installed condition. Have your maintenance lead assess wear and damage using the manual for that system. Agree how the sample fit is judged on a sound connection. A worn adapter lets almost any tip sit loose, so judge fit on a good one.
Caterpillar’s catalogue lists several GET systems and attachment methods and notes that configuration changes can affect fit. [2] That is why the connection on your bucket decides the order. Ask Lingfeng which system its offered tooth uses and how it is installed, including whether it needs a hammer.
Are the numbers in brackets interchangeable?
The table prints them next to the main reference with no drawing or supersession note. Put both numbers in your request and ask Lingfeng what each stands for. Get its written fit confirmation for the offered item, and keep the two numbers as separate stock codes until it does.
Say whether the quote includes pins and retainers
Compare quotes on the same delivery, piece for piece.
| Decision | Write into the quote |
|---|---|
| Tip only or set | Tip quantity, pin/retainer quantity and exact identifiers; state separately supplied pieces |
| Drawing and material | Revision, critical dimensions/tolerances and agreed material/heat-treatment requirements |
| Batch records | Lot mark, inspection report, acceptance criteria and who approves the sample |
| Packing and freight | Units per box/pallet, protection, shipment mass/dimensions and destination terms |
| Replenishment | Current availability, sample/bulk lead times, minimum quantity and substitution policy |
The product page gives no values for these fields. Settle them with your technical and purchasing team, then ask Lingfeng to answer each line. For a shipment with several references, ask for separate markings and counts per reference so your receiving team can check the delivery without sorting loose teeth by eye.
If the adapter is damaged, a new tooth will not fix the bucket. Have the connection assessed and follow an approved maintenance procedure. Welding, machining or modifying the attachment is work for your maintenance team under its own procedures.
Approve fit first, then measure wear on your own work
Your trial gives the wear figures Lingfeng does not publish.
Sample gate
Fix the Lingfeng item, drawing and retention pieces before the trial. Record the markings and the agreed dimension and fit checks. If a sample fails, write down the mismatch and Lingfeng’s revised proposal before you accept a different reference.
Operating records
Log the material handled, bucket setup, hours, reason for replacement and any maintenance. Keep the same records for your current tooth. Compare teeth only when they ran on the same bucket in the same material.
Caterpillar’s inspection guidance covers wear and damage on tips, adapters, retention and bucket areas, and tells owners to consult the operation and maintenance manual before service. [3] Follow the manual for your machine. Caterpillar’s performance figures describe its own parts, so measure Lingfeng’s on your bucket.
To compare cost, set the landed price of each tooth against your actual replacement and maintenance costs over a fixed operating measure. Lingfeng publishes no prices or wear life on this page, so cost per hour, savings and replacement intervals come from your own trial.
How should a successful sample become a repeat order?
File the approved drawing, Lingfeng item code, retention part markings and inspection records together. Require your approval for any change in material, shape, process or reference. Ask for batch marking on every later delivery so you can match each reorder to the approved sample.
Request one defined tooth reference
Edit the brief, then carry it into the RFQ.
