K3492 Synchronizer Kit for Eaton Fuller

The K3492 synchronizer kit is a service component for Eaton Fuller transmission rebuilding applications. The complete kit reference distinguishes it from individual synchronizer rings.

Match the transmission model and specify the required kit contents for the repair. Include the gearbox assembly identification and original component details with your enquiry.

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 K3492 reference identifies a synchronizer kit for Eaton Fuller transmission rebuilding, ordered as one kit-level delivery rather than as separate components. A kit groups the synchronizer parts for the service operation under a single reference, so one order covers the position being repaired, while an individual synchronizer ring covers one component only. The parts documentation for the corresponding application also lists the earlier kit reference K-2446, which belongs to the same service context. Checking the received components against the gearbox assembly identification, before installation begins, confirms that the delivery matches the synchronizer position planned for the rebuild.

• Kit reference: K3492, also written K-3492
• Earlier kit reference: K-2446
• Scope: synchronizer kit, distinct from individual synchronizer rings
• Application: Eaton Fuller transmission rebuilding

Because a kit contains several components, the match is made at assembly level rather than at component level. The gearbox assembly identification and the original component details recorded during the teardown describe what the kit must cover, and each delivered component is checked against that record before work starts. Where the removed parts carry markings, those markings support the comparison together with the transmission model. An enquiry that lists the required kit contents alongside the gearbox identification leaves no gap between the order and the repair.

• Match level: gearbox assembly identification, not single components
• Evidence: original component details from the teardown
• Comparison: markings on the removed parts plus the transmission model
• Order record: required kit contents listed with the gearbox identification

TOSEN reviews each K3492 kit order against the gearbox assembly identification and the original component details supplied with the enquiry. The components are compared with the synchronizer position named for the repair, and the required kit contents from the order are reviewed item by item. Quantity and destination complete the record, so the delivered kit matches the rebuilding plan that was agreed.

What does a synchronizer kit order cover?

A kit order covers the synchronizer components grouped under the kit reference for one service operation, delivered together instead of as separate items. The K3492 reference defines that grouping for Eaton Fuller rebuilding work, and the earlier K-2446 reference appears in the parts documentation for the corresponding application. The exact components are confirmed against the gearbox assembly identification during the enquiry, keeping the delivery aligned with the repair.

How does the kit reference differ from an individual synchronizer ring?

An individual synchronizer ring is a single friction component sold on its own, while the kit reference covers the components needed to service one synchronizer position. Ordering the complete kit therefore suits rebuilds where several worn parts belong to the same position, while a ring order suits a targeted repair of that one component. The order states which scope the job requires.

How are the kit contents verified before installation?

Verification starts from the gearbox assembly identification and the original component details recorded during the teardown. Each component in the delivery is compared with that record, covering markings, dimensions and the synchronizer position it serves, so nothing missing or extra travels to the bench. Where the removed parts carry no legible markings, photographs of the mating components support the check.

Which information does an order for this kit require?

The order needs the transmission model, the gearbox assembly identification and the original component details, together with the required kit contents and the quantity. Notes from the teardown about the synchronizer position under repair help the supplier check the kit reference. Recording those details in one message keeps the quotation and the delivery on the same basis.
