ZF 9 S 109 2004 Parts Catalog – 52 Pages of Factory Part Numbers

I’ve been torqueing bolts since before some of you were born. And if there’s one thing that’ll kill a rebuild faster than a stripped thread, it’s ordering the wrong part. That’s why this ZF 9 S 109 2004 Parts Catalog sits on my bench. It’s the genuine ZF publication for the 9 S 109 transmission, 52 pages of nothing but factory-approved part numbers and assembly configurations. No aftermarket guessing.

Transmission Configuration – What the Catalog Tells You

Page 2 of this catalog spells out the exact build of the unit. You’re looking at an ISUZU-spec 9 S 109 with a horizontal left flange mount, ratio spread from 10.24 down to 0.74, reverse 9.44. Input shaft length 320 mm, SAE 10C 1¾-inch journal. The catalog gives you the parts list number 1304 051 414. If you’re swapping a clutch housing, you need that SAE 2 dimension – page 3 shows it’s L=210.0 mm. ZF 9 S 109 2008 Parts Catalog covers later revisions, but this 2004 version matches the early ISUZU GXZ and FXZ trucks.

7 Systems Covered – From Heat Exchanger to Parking Brake

Don’t waste time hunting for a breather or a speedo drive gear. This catalog includes every subsystem: gearbox venting (breather), heat exchanger deletion code, retarder omission, parking brake preparation, and the full control setup with remote control horizontal RH. The spec sheet even lists the pawl stop spring force at RG=60N and gear detent at NG+GG=68N. That kind of data keeps you from ordering a mismatched spring pack.

Fluid Capacities and Oil Grades – Get It Right the First Time

Overfilling a 9 S 109 will blow seals. Underfilling kills the planet gears. Page 3 clearly states oil capacity: approximately 8.50 liters. Oil grade per ZF TE-ML02. No ambiguity. No “use any 80W-90” nonsense. If your customer’s ISUZU rolls in with a leaking output flange, you pull the part number from the catalog – not from a third‑party database that might have the wrong RA ratio (5.12 on page 3).

Does This Parts Catalog Include Exploded-View Diagrams?

Yes – but understand the format. This is a spare parts catalogue, not a step-by-step repair manual. The drawings (sections like 1304 051 410, 1304 172 171) are assembly illustrations that show each component and its position. You use them to identify the exact replacement item when you’ve got the transmission on the bench. For disassembly torque sequences, you’ll need the service manual. ZF 9 S 109 Parts Catalog is the same 52‑page PDF, no aftermarket reprints.

Source Authenticity – Why OEM Beats Aftermarket

I’ve seen aftermarket parts catalogs list a wrong input shaft length. That costs you a day and a customer. This catalog was printed by ZF Friedrichshafen AG in 2004 for the ISUZU application. The parts list number 1304 051 414 ties directly to the VIN codes on page 2 (model TRUCK GXZ 23 and FXZ). Every spring layout Q5, every pawl stop orientation, every speedo drive ratio 1.545 is verified in the factory system. Automotive Industry Overview confirms that ZF is a tier‑1 OEM supplier – this is their own documentation.

Who Should Buy This 52-Page Catalog

You’re a shop owner with a fleet of ISUZU trucks, or a home mechanic rebuilding a 9 S 109 for a project. If you’ve ever stared at a pile of parts and wondered which thrust washer goes where, this catalog ends that misery. It also lists the mass (190 kg approximate), paint code (Deep‑Black RAL9005 ZFN915W), and preservation spec KA2 T/KI2/S40. That matters when you’re ordering a replacement housing. ZF 16S151 ECOSPLIT III & 16S151 R 2007 Parts Catalog covers a different family, but the layout is identical – once you learn the ZF catalog numbering system, you can use any of them.

FAQ – Common Questions About This Parts Catalog

Is this the same as a service manual?

No. This is a parts catalog. It lists every nut, bolt, seal, and gear with its factory part number. For torque specs and overhaul steps, get the service manual.

What vehicles use the ZF 9 S 109?

The catalog references ISUZU trucks GXZ 23 and FXZ with GVW 26t and GCW 38t. Engine is 6SD1-TC 201 kW at 2200 rpm, clutch Daikin 380 mm slip torque 2621 Nm.

How do I read the ZF parts list number 1304 051 414?

That number is the master identifier for this specific transmission build. When you call ZF for a replacement part, they’ll ask for that number. It’s printed on page 2 and repeated throughout the book. Keep it with the transmission.

Can I use this catalog for a different ZF model?

Only for the 9 S 109 with the configuration shown. The catalog is specific to one ratio set and mounting. Other ZF models have different parts lists. Automotive Battery – sorry, unrelated, but you need a battery for the truck.

You’ve got a 9 S 109 on the lift, a bin of old parts, and a customer waiting. Don’t guess. Access the Factory Manual and get the right part number the first time.
