PROFESSIONAL LOOKUP
See the result. Understand where it applies.
A real SNTWET Service result: the model’s parts catalog comes through directly, with confidence labels and aftermarket cross-references on the core components.
Fitment & conditions
Keep model generation and serial-number conditions in view. Similar models do not automatically mean identical fitment.
Confidence & gaps
Distinguish Confirmed, Candidate and Inferred results, with clear next checks.
REAL CASES
From a line in the field,
to a direction you can check.
01Komatsu PC200-8 · Slow, underpowered movement (hydraulic check)
SNTWET Service — real response (verbatim)
Translated from the original Chinese response.
PC200-8 hydraulic system — common issues:
- Check the hydraulic oil level and condition first (replace if emulsified or discolored).
- Check the pilot filter (mounted at the rear left of the cab; clogging causes sluggish movement).
- Measure main pump outlet pressure (should be ≥30 MPa unloaded; below 25 MPa may indicate pump wear or a main relief valve fault).
- Listen for abnormal noise: a high-pitched whine usually means the pump is drawing air (check the suction line seal / strainer for clogging); a dull knock may point to a sticking servo valve.
The main relief valve, main pump regulator and PPC valve all need their parameters calibrated per the machine’s Service Manual.
Inferred · Verify before use
Confidence: Confirmed / Candidate / Inferred — unmatched details are flagged as a Gap.
02Caterpillar 320D · Pulls to one side while traveling
SNTWET Service — real response (verbatim)
Translated from the original Chinese response.
Which generation? The 320D could be the 320D (early), 320D2, or 320D2GC — the hydraulic filter, pilot filter, main relief valve and other parts are not interchangeable across generations. Please confirm the full model (e.g. “320D2”, or a photo of the nameplate); otherwise the part numbers and specs can’t be matched accurately.
Gap
Confidence: Confirmed / Candidate / Inferred — unmatched details are flagged as a Gap.
Excerpted from real SNTWET Service responses. Findings don’t transfer across models or generations — always verify on site against the machine’s service manual.
AVAILABLE IN PARTS AND SERVICE
Five everyday lookups.
One professional foundation.
01Parts lookup
+
Find parts and catalog figure numbers by machine model, location or part number, locate the assembly on the exploded view, and confirm generation and serial-number conditions before you swap the part.
02Maintenance lookup
+
Check service intervals, fluid capacities and procedure notes on site, resolved by machine model — never assumed from a similar-looking one.
03Filter lookup
+
Look up filter part numbers and aftermarket cross-references, so you know what will work on site even without the OEM part on hand.
04Seal lookup
+
Search by location for oil seal and repair-kit part numbers and specifications, and confirm fitment before you disassemble.
05Hose lookup
+
Identify the hose location and specification, with OEM fitting and crimping data to help judge whether it can be crimped on site or needs an OEM order.
CAPABILITIES
Start with the symptom.
Find a direction to investigate.
01Symptoms and fault information
+
Start with loss of power, slow movements, leaks, alarms or other symptoms. Add the full model and fault codes to find relevant systems and inspection references.
02Technical and system information
+
Find hydraulic, electrical, engine, repair and maintenance information, including relevant sections, procedures and precautions.
03Inspection paths and references
+
Use reference information to identify inspection sequences, tools and precautions for professional on-site verification.
04Parts catalogs and exploded views
+
Search catalogs by model and part number; where a diagram is available, locate components and understand assembly relationships.
05Part-code interpretation
+
Interpret specifications using supported coding rules such as Komatsu KES, distinguishing Confirmed records from Candidate and Inferred (rule-based) results.
06Conditions and information gaps
+
Distinguish Confirmed, Candidate and Inferred results, and identify missing details or conditions that need checking.
