Correct Identification of your Unit

Correct identification of your Transmission and/or Converter is critical. Gear Ratios, Speeds, Torque Curves are all matched precisely to your Machine & Engine, a miss-match in any of these areas would result in poor performance of your machine. The following guide will help you to correctly identify your unit.

Critical Information

Allison Transmissions & Converters

Model and Part Number (i.e. CLBT6061, P/No 23019914 or TCDOA475, 6880983)

Allison units also carry a serial number but this does not help identify the unit when using the Allison parts literature.

Clark Transmissions & Converters

Model Number (i.e. 13.7HR28334-7 or C273.5-14)

Clark units also carry a Serial Number but this does always help to identify the unit. Clark produce a separate a parts list for each model so the model number is crucial.

ZF Transmissions

Model & Specification Number (i.e. 6WG260, 4646 056 003)

All ZF units are stamped with a Serial Number. This is normally stamped into the top of the Main Housing and can be used to identify the unit when the identification plate is missing or has been removed.

Twin Transmissions & Clutches

Model & Specification or BOM number (i.e. TD-44-1132, Spec 63176 or 8FLWB1701, Spec 65469)

Dependent on where the unit was built (US or Belgium) Twin Disc units have a Specification number or a BOM (Bill of Materials) Number on the identification plate.
