Fitment verification
Confirm the transmission model, gear position, stamped number, spline count, outside diameter and clear photos of both faces. FAST Gear transmissions may have production revisions, so confirmation should be completed before ordering.
Inspection, packing and export
Top Run checks visible part numbers, interfaces and shipment condition before dispatch. The packing method is selected for the component: machined metal surfaces receive corrosion protection, precision parts receive cushioning, and open ports or connectors are protected from contamination and moisture.
Frequently asked questions
What symptoms may indicate synchronizer wear?
Gear clash, difficult engagement or a gear that disengages can justify inspection, but the complete shift system should be checked before replacement.
Can synchronizers with similar dimensions be interchanged?
Not safely by appearance alone. Verify the exact transmission family, gear position, spline and reference number.
What should be sent for quotation?
Send the gearbox nameplate, old-part number, dimensions and front-and-back photos.
