ZF 4 WG 160, HL740-7A 2014 Parts Catalog – OEM Factory Specs

If you have ever ordered a seal or a bearing for a ZF 4 WG 160 transmission using an aftermarket parts list, then you know the wasted time and the wrong part that shows up. That day when the counter guy tells you “it should fit” is the day you learn to stick with OEM documentation. This ZF 4 WG 160, HL740-7A 2014 Parts Catalog is the real thing – 72 pages of factory-issued part numbers, figure references, and cross-indexed assembly views. Printed by ZF Friedrichshafen AG, dated 07.11.2014. Not a copy, not a reprint from some third-party (those are garbage). It is the exact list that ZF technicians use to order components for the 4 WG 160 and the HL740-7A torque converter.

Parts Breakdown for the 4 WG 160

The catalog splits the transmission into logical assemblies: the main housing, shift turret, cover plates, and the internal shaft group. On page 2 you will see the “Notes relating to the spare parts catalog” – read that before you start. It explains the position numbering system: subpositions like /0120 indicate individual items within a completed assembly. For example, position 0370 may include a centering pin listed as /0120. If you miss that note, you might order the whole assembly when you only need the pin. The manual uses “positions” and “subpositions” – that matters when you call ZF with a part number.

HL740-7A Torque Converter Components

This catalog covers the HL740-7A converter as part of the 4 WG 160 package. The OCR shows reference numbers like 068.08.17 (AUSLEGER WL SHIFT TURRET) and 068.08.06 (DECKEL COVER) – those are tied to figure sheets. Each figure has an associated parts list. The HL740-7A items are grouped under similar figure numbers. You get the seal ring (0634.801.249) and the compression spring (0732.040.736) with exact dimensions. Use those numbers to cross-check against what is currently in your transmission.

How the Catalog Is Organized

Don’t expect a step-by-step repair guide – that is not what this is. This is a Parts Catalog, period. The structure: a cover sheet, then overview of figures, followed by figure-parts list pairs. Each figure shows an exploded view; the parts list beneath it gives the Sachnummer (product number), description, technical info, quantity, and unit (Stk = pieces). The “gap” notation means no separate poster exists for that assembly – the part is shown within the main figure. Take the time to learn the flow: figure number, then position numbers on the drawing, then the list. It saves you from ordering the wrong revision.

Why You Need OEM Part Numbers

Aftermarket catalogs often combine multiple revisions or use superseded numbers that are not backward-compatible. This ZF catalog uses the exact 2014 revision status. The material number is 4656.054.117. That ties to the specific build of the 4 WG 160. If you need a part for a HL740-7A converter, the OEM number from this catalog is the only one ZF will honor when you call their Passau plant. I have seen guys try to use a generic seal and end up with a leak that took out the clutch packs. Stick with factory data. For other ZF transmissions, check the ZF 16S151 ECOSPLIT III & 16S151 R 2007 Parts Catalog or the ZF 16S221 ECOSPLIT III 1316 2007 Parts Catalog OEM Specs for similar accuracy.

3 Common Mistakes When Ordering ZF Parts

First mistake: ignoring the “dotted display” parts. Those are shown only for orientation – they are not included with that figure’s kit. Second mistake: mixing up positions with subpositions. If the catalog shows “0370” and then “/0120” beneath it, the /0120 is a separate line item. Third mistake: assuming a part number from a different 4 WG variant (like 4 WG 180) will work. The 4 WG 160 and HL740-7A have specific revisions listed on page 1. Do not guess. Use the OEM numbers from this 72-page document. For a broader look at ZF driveline documentation, see the ZF 16 S 2521 TO 2010 Parts Catalog – OEM Factory Specs.

Does This Catalog Cover the Full Transmission?

Yes, it covers the 4 WG 160 transmission assembly including the HL740-7A torque converter, shift turret, covers, connecting parts, and fasteners. It does not cover the electronics beyond the mechanical parts list – there is no wiring diagram or diagnostic procedure. For electrical diagnostics, refer to a separate service manual. The Automotive Industry Overview at Wikipedia gives context on transmission evolution, but for part numbers, this catalog is your lock.

Can I use this catalog for a 4 WG 180?

Only if the HL740-7A torque converter is shared. The 4 WG 160 and 180 have different shaft lengths and bearing sets. Check your material number against the one printed on page 1 (4656.054.117).

Are the part numbers still current for a 2025 rebuild?

ZF updates parts every few years. This 2014 catalog gives you the baseline numbers. You may need to check ZF’s latest e-catalog for supersessions. But without this, you cannot even start.

Does it include torque specs for bolts?

No. This is a parts catalog, not a service manual. Torque values are not listed. You need the separate ZF service manual for the 4 WG 160. The parts catalog only tells you what part number to order.

What is the difference between this and a reprint?

Reprints often have blurred figures, cropped page numbers, and missing notes. This is the original 72-page PDF from ZF – every page, every footnote, exactly as printed in 2014. The Automotive Battery article is irrelevant here; focus on the transmission.

The time you waste hunting for the right part number because you trusted a generic list is billable hours down the drain – or worse, a customer’s transmission spread across your bench with the wrong seal. Buy the genuine ZF catalog. Access the Factory Manual and start ordering parts that fit the first time.
