Haiyutong BS4208 / BS428 transmission: identity clarification

What the source identifies

The heading and image label say BS4208, while the body says BS428 and describes four forward and two reverse gears with a separately arranged YJ315-series converter.

Keep the version and application explicit

The BS4208/BS428 discrepancy remains unresolved. This single clarification page does not declare the two codes equivalent or create two product offers. Request a current nameplate, full code and written correction before using the table or ordering.

Questions before a comparable quotation

Which installed assembly is being replaced?

Provide the machine make, full model and serial identity, engine and transmission or converter nameplates, existing complete part numbers and safely accessible photographs. No dismantling or diagnostic procedure is prescribed.

Which version and interface must match?

Request the complete supplier code and current drawing, ratio or converter version, mounting and flange details, control interface and a written matching basis for that specific machine. Similar yellow or grey castings do not establish interchangeability.

What is included and how is it documented?

Separate the complete assembly from turbine, valve, pump, coupling and other subcomponents. Agree included parts, condition, current documents, warranty exclusions and the process for resolving code differences before ordering.

From this reference to a purchase request

Keep the offered product identity, quantity, application and delivery destination in one written requirement. Compare the supplier’s dated documents and exclusions alongside price, lead time, warranty and support responsibilities. The existing supplier and procurement tools below help prepare that information; opening a link does not send a message or count as a completed or effective enquiry.

Source and evidence boundary

The company-controlled product body and mapped original image were reviewed directly. The page is undated unless its source says otherwise; the review date is not a product launch date. Supplier descriptions and nominal catalogue figures are attributed reference information, not independent performance, safety, conformity, fitment or stock verification. Obtain documents for the actual offered version and resolve any difference before ordering. This page provides no installation, repair, energising or operating procedure.
