OEM 1316 304 159 Synchronizer Cone Synchronizer Ring For Mercedes Benz Gearbox

Synchronizer Cone for Mercedes Benz Gearbox OEM 1316 304 159

1. Quick Notice

Confirm the OEM number 1316 304 159 on your original synchronizer cone before ordering. This component fits ZF manual transmissions in Mercedes-Benz trucks. Verify transmission model (16S150, 16S151, 16S220, 16S221, 16S251) and gear position (3rd/4th typically). Professional transmission technician required for installation. Use GL-4 gear oil only.

2. Description

The 1316 304 159 synchronizer cone is a precision transmission component for Mercedes-Benz trucks equipped with ZF heavy-duty gearboxes. This cone fits between the synchronizer hub and gear, facilitating rotational speed equalization before gear engagement. Manufactured from 20CrMnTi carburized steel with a precision-machined friction surface featuring an oil evacuation pattern for rapid fluid clearance during shifting-26-. Suitable for ZF 16S150, 16S151, 16S220, 16S221, 16S251 series transmissions, typically in 3rd/4th gear synchronizer assemblies-1. Also compatible with DAF LF55 (2006–2012), ASTRA trucks equipped with these ZF gearboxes-13-26. Cross-references include 1316304159, 42543324, 1643380, 81324250158, 82324250009, 5001864642, and 130438-13. Common failure symptoms include grinding during 3rd/4th gear shifts, difficult gear engagement, and transmission noise. Replacement restores proper shift quality.

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

Transmission Identification: Locate the transmission model plate on the gearbox housing. Compatible models include 16S150, 16S151, 16S181, 16S182, 16S220, 16S221, 16S222, 16S251, and 8S151 series-13. This cone is typically used in 3rd/4th gear synchronizer positions for 16-speed ZF transmissions.

Oil Requirement: Use GL-4 80W-90 gear oil only. GL-5 oil contains extreme pressure additives that damage synchronizer components. Verify oil specification before filling after reassembly.

5. FAQ (One by One Question and Answer)

Q1: Which Mercedes-Benz transmissions use the 1316 304 159 synchronizer cone?
A1: This cone fits Mercedes-Benz trucks equipped with ZF 16S150, 16S151, 16S220, 16S221, 16S251 series transmissions, typically in 3rd/4th gear synchronizer assemblies.

Q2: Is this cone compatible with other truck brands?
A2: Yes. It also fits DAF LF55 (2006–2012) and ASTRA trucks equipped with compatible ZF transmissions-26-13.

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

Q4: Is this a steel or bronze synchronizer cone?
A4: Steel. Manufactured from 20CrMnTi carburized steel. A magnet will stick to this cone-26.

Q5: How many cones are needed per transmission?
A5: Each gear position requires one synchronizer cone. A 16-speed ZF transmission contains multiple cones for different gears. Verify which gear position is failing before ordering. This listing is for a single synchronizer cone.
