ZF 16 S 151 2004 Parts Catalog

If you’ve ever ordered a seal or bearing for a ZF 16 S 151 transmission and ended up with a part that didn’t line up, you already know why a factory parts catalog matters. Third-party aftermarket lists leave out the details – like which ratio series your box uses or whether the servo piping is plastic or metal. This is the real thing: ZF’s own 2004 release, 49 pages of exploded views, part numbers, and configuration codes. No guesswork.

Gear Ratios and Configuration Data

Page 2 of this catalog lays out the exact ratio series for the ZF 16 S 151 – DG basis with 16.47 to 1.00 forward gears and a reverse of 15.42. You get the S-series ratios too: 13.86 down to 1.00. If you’re rebuilding or swapping internal parts, you need to know which planet gear set (I=4.583, 5-gear spur) and whether your box has the BK-synchronized clutch. That data is right there in the tech sheet, not buried in a service manual you don’t own. Use it to cross-check every part before you order.

Does This Catalog Include Assembly Instructions?

It does – but only as reference drawings. Page 4 lists M50 Assembly Instructions, and the earlier pages show sections (1315 051 100, 1316 101 035, etc.) with installation drawings. This isn’t a step-by-step rebuild guide; it’s the factory parts breakdown. You get the exploded views that tell you which bolt, washer, and shaft belongs where. If you need torque specs or overhaul procedures, you pair this with the service manual. But for ordering parts, this is the only document you should trust.

49 Pages of Factory Part Numbers

Every page is part of the ZF ELCAT system – the same database dealers use. The parts list number is 1315 051 324, tied to customer IVECO-M. You get item numbers, text descriptions, modifications (mod. no.), and the exact ZF part number. For example, the input shaft: L=117.0mm, SAE 10C 2 inch journal, spline length 91.000mm. That level of detail keeps you from gambling on a used shaft that might be the wrong length. The catalog runs from page 1 through page 49, serialized and dated July 30, 2004.

Get the Right Part Number the First Time

Look at the configuration codes on page 2: F06 installation position – hor. LH, flange mounted. F34 control: remote control, horizontal RH, H-H shift assistance with servo RH. If your transmission has a different servo orientation, the part numbers change. The catalog lists every permutation: plastic piping, ZULUFTABSPERRVENTIL (air shutoff valve), and the spring forces (detent spring HF=120N, pawl stop RG=60N). Don’t rely on a generic parts list that assumes all 16 S 151 units are the same. They aren’t.

ZF 16 S 151: Understanding Customer Specs

The customer is IVECO-M, but the data applies to other 16 S 151 boxes built to similar specs. You can see the ratio series basis (DG), the planet gear set details, and the separate clutch synchronization pattern (1-4 gear BK-synchronized). The catalog also covers the pulse transmitter tacho options (6.00 impulses per revolution) and the switch configurations (RG closing, NG opening, GP closing). If you’re retrofitting a tacho or adding a switch, the part numbers and installation drawing references are here. Related catalogs include the ZF 16 S 151 Parts Catalog for earlier builds, the ZF 16 S 151 2009 Parts Catalog for later updates, and the ZF 16S151 ECOSPLIT III & 16S151 R 2007 Parts Catalog for ECOSPLIT variants. For broader context on how ZF transmission parts integrate into drivetrains, the Automotive Industry Overview and Automotive Battery articles cover general systems that interact with the transmission electronics.

Frequently Asked Questions

Is this the same as the service manual?

No. This is a parts catalog – exploded views and part numbers. No torque specs or rebuild steps. You need the service manual for that.

How do I find the correct part number for my transmission?

Start by identifying your transmission’s configuration: check the ratio series (DG or S), the installation position (FLANGE MOUNTED, HOR. LH), and the shift assistance type (SERVO RH). The catalog’s tech sheet on page 2 gives you all those codes. Then match them to the sections. For example, if your input shaft is SAE 10C 2 inch with a journal diameter of 25 F7 and shaft diameter 50.30, look up the section drawing 1315 651 004. The item numbers in the drawing correspond to the part numbers listed. If you still can’t find it, cross-check the parts list number (1315 051 324) – that’s the master key for your specific IVECO-M variant. Once you have the ZF part number, order from any dealer that respects OEM data.

Does the catalog cover the ECOSPLIT versions?

This 2004 catalog is for the base 16 S 151 DD with DG ratio series. ECOSPLIT III variants have different gear sets and part numbers. Use the ZF 16S151 ECOSPLIT III & 16S151 R 2007 Parts Catalog for those.

Can I use this for other ZF transmissions?

Only if they share the same parts list number or ratio series. The data is specific to the 16 S 151. For other models, get their own factory catalog.

Forty-nine pages of factory ZF data, direct from the 2004 ELCAT system. If you’re maintaining or rebuilding a 16 S 151, this catalog saves you the headache of wrong parts and non-matching seals. Access the Factory Manual from AutoRepairManuals and keep a copy on your shop tablet or printed in your binder.
