ZF 16 S 221 2004 Parts Catalog – Official OEM Parts Data

Description

I’ve seen too many transmissions stacked in a corner because someone ordered the wrong seal or bearing. The part number was close, but not exact. That’s a waste of time and money. You need the actual factory documentation, not a copy of a copy. This ZF 16 S 221 2004 Parts Catalog is the real deal – 51 pages of OEM part numbers and technical specs straight from ZF Friedrichshafen AG. No aftermarket guessing.

ZF 16 S 221 Parts Catalog: What the Factory Includes

This is a parts catalog, not a repair manual. Don’t expect torque specs or assembly steps – that’s a different document. What you get is the complete ZF ELCAT CD-ROM 1/2004 data printed to PDF. It covers the 16 S 221 transmission built for Iveco-M, with ZF parts list number 1316 051 350. Page 2 gives you the technical information sheet: gear ratios (13.86 to 0.84), planetary set I=4.583, input shaft length, spline dimensions, and more. Page 3 starts the actual parts list with item numbers, descriptions, and ZF part numbers. Every nut, bolt, switch, and gasket is listed. If you need to identify a component or order a replacement, this is the source.

Does This Catalog Cover Every Nut and Bolt?

Yes, it lists all major assemblies and subcomponents. Input shaft, output flange, bearings, synchronizers, PTO drives, shift mechanisms, switches – they’re all there. The OCR excerpt on page 3 shows the technical info sheet with codes like G30 (switch), G36 (switch), K62 (PTO type N221PL), and pump specs. The catalog includes the full range of optional equipment, from heat exchanger prep to pulse transmitters. But remember: this is a parts catalog. It tells you what goes where and gives you the ZF part number to order. It does not tell you how to install it. You still need a service manual for that.

Why OEM Documentation Beats Aftermarket Reprints

Aftermarket parts catalogs often have typos, wrong supersessions, or missing revisions. This is original ZF factory data from 2004 – the same CD that dealers used. No third-party reprint. The part numbers match exactly what ZF stamped on the transmission. For background on transmission types and industry standards, you can check the Automotive Industry Overview. If you’re working on a vehicle that uses a Automotive Battery for shift assist, note that the catalog includes the servo control components and switches that interface with the electrical system.

3 Critical Specs You Get from This PDF

1. Transmission identification: The technical sheet on page 2 lists the customer spec number 8851760, type number A16, installation position, and ratio series. This lets you confirm you have the exact 16 S 221 variant.
2. Gear ratios: The scan shows 13.86 to 0.84 with split groups. If you’re rebuilding or replacing a transmission, you need to verify these match your vehicle – especially for highway vs. offroad use.
3. PTO and pump specs: The catalog details the power take-off type N221PL, pump type 8605/07, and mounting interface. Ordering the wrong PTO can cost you days of downtime.

Page 2 gives you all the ratios; page 3 breaks down the parts list. That’s two major data points in one document.

Match Your Transmission VIN to the Correct Part

Use the customer spec number and type number from the transmission tag. The catalog’s technical info sheet lists the exact configuration: horizontal LH flange mount, remote control, servo RH actuation, plastic piping, and more. Compare the code string (SG-KK*LL*ANGEFL*DW-WR H-H *N221PL*SERVO-WR) with your transmission. Then find the part you need in the item list. No guesswork – the ZF part number is right there. For example, if you need a detent spring, the catalog lists spring force HF=120N and lever layout version A. That’s the kind of detail you won’t find in a generic aftermarket listing.

Is this a repair manual?

No. This is a parts catalog for ordering components.

How do I use this catalog to find the right part for my 16 S 221?

Start by locating the transmission tag on your gearbox. Note the customer spec number (e.g., 8851760) and type number (A16). Open the PDF and go to page 2 – the technical info sheet lists the exact configuration code for that spec. Confirm your transmission matches. Then go to page 3 and find the parts list section that matches your transmission code. Each item has a ZF part number. Use that number to order from any ZF dealer. If you’re unsure about a code like G30 or K62, the catalog includes description abbreviations that are consistent across ZF documentation. Cross-reference with the parts list and you’ll have the correct component every time.

This catalog eliminates the headache of mismatched parts. Access the Factory Manual and get the exact ZF data you need for your 16 S 221 transmission. No reprints, no guesswork – just the OEM parts list.
