Steel Alloy SYNCHRONIZER RING 1316304168 Chassis Parts Synchronizer Cone

Confirm the OEM number 1316304168 on your original synchronizer ring before ordering. This ring is suitable for ZF 16-speed manual transmissions. Verify transmission model (16S150, 16S151, 16S1650, 16S220, 16S221, 16S251, etc.) and gear position. Professional transmission technician required for installation.

The 1316304168 synchronizer ring is a precision transmission component for ZF heavy-duty truck gearboxes. This ring fits between the gear and synchronizer hub, equalizing rotational speeds before tooth engagement during shifting. Manufactured from high-strength steel alloy with a precision-machined friction cone. The inner surface features an oil evacuation pattern designed for rapid fluid clearance during shift initiation. Suitable for ZF 16S150, 16S151, 16S1650, 16S181, 16S220, 16S221, 16S251 series, plus 16S182, 16S192, 16S252 variants and additional ZF gearbox models. Also compatible with vehicles from DAF, equipped with these ZF transmissions. Worn rings produce grinding noises during shifting, gear clash, or difficulty engaging gears. Replacement restores proper synchronization and shift quality.

Transmission Identification: Locate the transmission model plate on the gearbox housing. Compatible models include 16S150, 16S151, 16S1650, 16S181, 16S182, 16S192, 16S220, 16S221, 16S222, 16S251, 16S252, and 16S2723. Also fits 8-speed ZF variants including 8S151, 8S162, and 8S182 series. This ring may serve 3rd/4th gear positions in certain ZF transmissions.

Installation Check: Before assembly, examine the mating gear cone for scoring or glazing. The ring must produce resistance when pressed onto the gear cone and twisted. No resistance indicates wear requiring replacement. Install with the wider taper opening facing the gear cone.

Oil Requirement: Use GL-4 80W-90 gear oil. GL-5 oil damages synchronizer components. Verify oil specification before filling after reassembly.

Q1: Which ZF transmissions use the 1316304168 synchronizer ring?
A1: This ring fits ZF 16S150, 16S151, 16S1650, 16S181, 16S182, 16S192, 16S220, 16S221, 16S222, 16S251, 16S252, and 16S2723 series, plus 8S151, 8S162, and 8S182 series.

Q2: Which truck brands are compatible with this ring?
A2: Vehicles from DAF,  and ASTRA equipped with compatible ZF transmissions use this ring.

Q3: How do I test my old ring for wear?
A3: Press the ring onto the mating gear cone and twist by hand. A functional ring locks or provides strong resistance. A worn ring spins freely with no friction.

Q4: Is this a steel or bronze synchronizer ring?
A4: Steel alloy (20CrMnTi or equivalent). A magnet will stick to this ring.

Q5: How many rings are needed per transmission?
A5: Each gear position requires one ring. Verify which gear position is failing before ordering. This listing is for a single synchronizer ring.
