1316304170 Synchronizer Ring for ZF Transmissions

The 1316304170 synchronizer ring is a replacement component for ZF transmission applications. Match the reference number and ring geometry to the gearbox being rebuilt.

Compare the cone profile, engagement teeth and dimensions with the original ring. Include the ZF transmission model and assembly identification when requesting a quotation.

Send the gearbox code, part number or component markings, dimensions and quantity. Include the gear position and photographs of the mating components where available.

The 1316304170 synchronizer ring is a replacement component for ZF transmissions, identified by its reference number and by the ring geometry that goes with it. The ring is the friction and timing element of its synchronizer position: pressed against the mating cone during a shift, it reduces the speed difference between the rotating members and times the moment the sleeve engages. The reference number ties the order to the exact ring defined for that position, so the geometry check confirms what the number already promises.

• Reference number: 1316304170
• Component: synchronizer ring, friction and timing element
• Application: ZF transmissions
• Match basis: reference number plus ring geometry

The ring is matched to the gearbox through the reference number first and the geometry second. The cone profile and the engagement teeth of the original ring are compared with the replacement, and the dimensions are checked in the same pass, because a correct number with a worn or deviating original leaves the comparison short. The ZF transmission model and the assembly identification complete the record, placing the ring at the right position in the right gearbox.

• Primary check: 1316304170 reference number
• Geometry: cone profile and engagement teeth of the original
• Dimensional check: ring dimensions in the same pass
• Record: ZF transmission model and assembly identification

TOSEN checks each 1316304170 enquiry against the reference number, the ZF transmission model and the assembly identification recorded by the buyer. The cone profile, the engagement teeth and the dimensions supplied from the original ring are reviewed against the order, and the quantity with the destination completes the record before the quotation is issued.

How is the 1316304170 ring identified and matched?

The reference number is the first identifier, read from the gearbox documentation or from the removed part, and the ring geometry is the second. Cone profile, engagement teeth and dimensions are compared between the original and the replacement, so the number and the geometry agree. The ZF transmission model recorded with the enquiry places the ring in the right assembly.

How do a synchronizer ring and a synchronizer hub differ?

The ring handles the friction and timing work of the position, pressing against the mating cone to match speeds and controlling when the sleeve engages, while the hub carries the synchronizer on the shaft and presents the splines the sleeve slides on. The two are inspected and ordered separately under separate references. A rebuild can call for either one without the other.

Which features of the original ring support the comparison?

The cone profile defines the friction interface, the engagement teeth define the timing, and the overall dimensions define the fit at the position. Those three features, read from the removed ring, are what the replacement must reproduce. Photographs of the original part help where the features are hard to measure directly.

What information should a ZF synchronizer ring quotation request contain?

The request carries the reference number, the ZF transmission model and the assembly identification, together with the dimensions and the quantity. The gear position and photographs of the mating components complete the record. On that basis TOSEN verifies the ring and issues a quotation tied to the gearbox being rebuilt.
