What the official reference establishes
The manufacturer lists this exact code in its China III forklift-engine table. Keep the G31 suffix: 4D29X41 in the China IV table is a different published designation, not an interchangeable spelling.
Define the work before choosing a configuration
A replacement enquiry should begin with the installed engine nameplate and serial number. Record the engine application, pump identity, flywheel/bellhousing and mounting arrangement. The manufacturer table puts this code in a 2–3.0-tonne application class, but truck capacity class alone cannot establish engine compatibility.
Keep the supply package explicit
The China III table groups naturally aspirated VP/VE pump wording across multiple rows. Confirm the exact fuel-system package and calibration for the offered engine. Adjacent 4N23G31 rows list several powers; they do not create alternative ratings for 4D29G31.
Questions for the proposed product
What exactly is being quoted?
Specify complete engine, long block or another assembly. Require the full model, serial/build identity and current specification. List flywheel housing, starter, alternator, fan, fuel system, controls and other auxiliaries as included or excluded.
What evidence is needed for a replacement?
Provide the installed engine nameplate and serial, truck identity, component labels and interface drawings. Require a written model/configuration match from the responsible supplier and qualified technical review; visual resemblance or a capacity class is insufficient.
How should technical and commercial scope be compared?
Give each supplier the same application and assembly scope. Compare current drawings, controls, destination documentation, delivery, warranty and after-sales responsibilities. No availability, lead time or certification is established by this reference.
From product research to a comparable request
Prepare a written engine requirement around the installed full model and serial, truck identity, interface drawings, duty and destination. Compare the complete assembly scope, controls, documentation, delivery and support. Keep unresolved items visible. One matching code or displacement cannot replace a current configuration and interface check.
Sources and evidence boundary
The official company introduction identifies Zhejiang Xinchai Co., Ltd. (浙江新柴股份有限公司) as a diesel-engine and related-component business. Its published address is No. 888 Xinchang Avenue West, Xinchang County, Shaoxing, Zhejiang, China. Each selected technical table and associated manufacturer image was reviewed. Product pages are undated; catalogue classifications and image paths are not new-launch dates. Manufacturer emissions headings are preserved for version identification, not adopted as independent legal approval or certification. Confirm the current build, application, destination documentation and responsible contracting entity. No stock, authorization, truck fitment, safety or performance guarantee is established. These references provide purchasing preparation, not installation, fuel-system adjustment, operating or return-to-service instructions.
