ZF 2025, 2035, 2045, 2060 2002 Repair Manual – Factory Specs for Planetary Steering Axles

You’ve got a ZF planetary steering axle on the bench—2025, 2035, 2045, or 2060. You’ve got no time for guesswork. You’ve got a box of parts and a prayer. The problem with aftermarket documentation? It’s copy-paste garbage. You torque a bolt to a spec from a third-party site, and next week you’ve got a drip. This 2002 factory manual from ZF is what you need. It’s 163 pages of procedures written by the engineers who designed the axle, not a marketing department. Every torque value, every bearing clearance, every special tool—it’s all here. If you skip steps, this manual will call you out. That’s the point.

Wasted billable hours eat your profit. Stripped bolts from wrong torque specs cost you parts and reputation. That’s why you reach for the factory book—not a third-party rehash. The manual opens with General Working Instructions and a section on Labour Safety (page 0.03). It’s not fluff; it tells you how to handle hydraulic oil, support heavy assemblies, and avoid pinch points. Follow it. Then you hit the ZF 2025, 2035, 2045, 2060 2002 Repair Manual bread-and-butter: Technical Data and Adjustment values on page 0.09, Torque limit for screws on page 0.12, and the List of Special Tools from W-1 to W-14.

163 Pages of Factory Procedures – From Disassembly to Torque Specs

This manual covers four axle models: 2025, 2035, 2045, and 2060. Publication year is 2002. No updates, but the design hasn’t changed on these planetary steering axles. The table of contents is a workbench map. You get the Conversion Table for Dimensional Units (page 0.10) so you can switch between Nm and ft-lb. You get the Denomination of Legal Standards (page 0.11) because even Germans want you to use the right bolts. The Illustrated Tables (W-15 to W-40) show cross-section views with parts numbered. That’s how you know you’re putting the thrust washer in the right orientation. The Disassembly and Reassembly section spans pages 1.01 to 2.17, starting with the planet carrier. Version A and Version B bearings are both detailed. If you have the steering angle sensor option, there’s a separate procedure on page 1.08.

Torque limit for screws – Why You Need the Factory Number

Page 0.12 lists the torque limit for screws in Nm. Convert them using the table on page 0.10. Aftermarket manuals copy numbers from Wikipedia or forums—I’ve seen M12 bolts torqued to 80 ft-lb when the factory calls for 110 ft-lb. That’s a leak waiting to happen. This manual gives you the exact values for screw grades 8.8, 10.9, and 12.9. It also tells you when to use threadlocker. The tolerance is tight. Use a calibrated torque wrench, not a breaker bar and a prayer.

Disassembly of the Planet Carrier – Versions A and B

Pages 1.01 to 1.03 walk you through the planet carrier removal. Version A bearing uses a snap ring and shims; Version B uses a nut and lock washer. The manual shows you which special tool to use: the puller for the planet carrier bearing (tool no. given in the W section). Without that puller, you’ll distort the bearing cage. The reassembly sequence specifies backlash for the bevel gear set. Contact patterns for the Gleason gear-tooth system are shown on pages 0.06–0.07. You need paint to check the pattern—don’t skip that step.

Is This Manual for the Weekend Mechanic or the Shop Owner?

Both, but with a warning. If you’re a home garage enthusiast who’s never torn down a planetary axle, read the Labour Safety section twice. The axle assembly weighs over 150 lbs—support it correctly. The manual assumes you have access to a press, hydraulic pullers, and a dial indicator. If you don’t, stop and buy the tools. A shop owner will appreciate the time saved: no trial-and-error, no trips to the dealer for a torque spec. Beginners can follow the step-by-step disassembly if they respect the order. Each subassembly (hub, joint housing, double-joint shaft, axle casing) has its own dedicated subsection. You work from the outside in.

OEM Documentation vs. Aftermarket – Know the Difference

This is a direct scan of the ZF factory manual, order number 5871 693 002, third edition dated March 1, 2002. It includes the official copyright statement from ZF Passau GmbH. Aftermarket manuals are often photocopies of photocopies—blurry diagrams, missing pages, wrong torque tables. This one has clean text and legible drawings. The OCR excerpt shows the original German-English hybrid wording: “Important Informations concerning the Labour Safety.” That’s factory copy. You’re not getting a reprint; you’re getting the same document that ZF dealership technicians used. Automotive Industry Overview

Get the Right Tools Before You Touch the Axle

Section W lists 14 pages of special tools. Examples: a puller for the planet carrier bearing, a wrench for the internal gear carrier, a seal installer for the hub. The manual doesn’t say “use a screwdriver to pry out the seal”—it tells you the exact tool number. You can source equivalents, but the dimensions are given in the Illustrated Tables. Without the correct tool, you risk damaging the sealing surface. The torque limit for screws on page 0.12 also requires a torque wrench that reaches 500+ ft-lb for the hub nut. ZF 6WG 310 1999 Repair Manual – Factory Specs for 6WG 310 covers a different product line but shows the same commitment to accurate specs.

Frequently Asked Questions

Can I use this manual for a different ZF axle model?

No. This covers only the 2025, 2035, 2045, and 2060 versions.

What if I don’t have the special tools listed on page W-1?

You can improvise, but you risk damage. The manual’s drawings show exactly where to apply force for pressing bearings and pulling seals. Without the correct puller for the planet carrier bearing, you might warp the carrier. The torque limit for screws on page 0.12 is also vital – use a calibrated torque wrench. If you can’t get OEM tools, at least use equivalent pullers and sleeves. Skip the tools and you’ll be doing this job twice. A shop press is mandatory for the hub assembly. The manual expects you to have a press capacity of at least 20 tons. Don’t try to hammer a bearing in – you’ll brinell the race. Follow the factory procedure, get the tools, and it’s a one-time rebuild.

This manual is the difference between a rebuild that holds oil and one that leaks after 500 hours. Don’t waste your time with knockoffs. Access the Factory Manual and get the job done right.
