Tadano FAUN ATF 80-4 Service Manual

If you are turning wrenches on a Tadano FAUN ATF 80-4 Service Manual that has 882 pages of factory-correct procedures, you already know the difference between a job done right and a job that comes back on a hook. Every time I see a crane come in with stripped boom cylinder bolts or a hydraulic leak that traced back to a torque spec pulled from a forum, I want to throw a torque wrench at someone. That is exactly why this manual matters. It is the OEM document from Tadano FAUN GmbH, not a reprint cooked up in someone’s basement. You get the same data the factory techs use in Lauf a.d. Pegnitz.

882 Pages of Factory Procedures

This manual runs 882 pages. That is not filler. It covers the entire ATF 80-4 – engine, transmission, hydraulics, electrical system, superstructure, outriggers, and the structural frame. Page 2 alone has the factory paint care instructions and a warning about steam-jet units before the paint hardens. Little details like that keep a crane from looking like a rust bucket after two seasons on a Texas construction site. Need the charge pressure for the main pump? The manual breaks down each system with step-by-step disassembly, inspection limits, and reassembly torque values.

What Torque Values Are Listed?

The manual lists torque values for every critical fastener on the ATF 80-4: engine cylinder head bolts, transmission housing bolts, hydraulic manifold fittings, wheel lug nuts, and boom pivot pins. All values are given in Nm and ft-lbs – you get both because some of us still think in foot-pounds. And I do not care how many years you have swung a wrench: never assume a torque spec from another crane model applies here. The ATF 80-4 uses specific materials and thread treatments. That is why you need the OEM page. The manual also includes tightening sequences and angular degrees where required – no guesswork.

3 Systems That Save You Time and Parts

1. Hydraulic System – The manual gives you the full hydraulic circuit diagram, component locations, and bleed procedures. You will find pressure test points and relief valve adjustment specs. 2. Electrical System – Wire color codes, connector pinouts, and the full wiring diagram for the control system. This is not a generic drawing; it matches the harness from the factory. 3. Transmission and Driveline – The manual covers the manual transmission (see Manual Transmission for basic principles) and the transfer case. Shift pattern, gear ratios, and overhaul specs are all there. Manual Transmission knowledge helps, but the real data is in this manual.

Get the Right Transmission Data

The transmission chapter includes clutch adjustment, bearing preload, and shift fork clearance. If you are working on a crane that has spent years in a quarry, you know the syncros wear out. The factory manual tells you wear limits and the correct replacement parts by OEM number.

Hydraulic System: Factory Bleed Procedures

Bleeding the main hoist circuit on the ATF 80-4 is not the same as bleeding a pickup truck clutch. The manual walks you through the sequence: start with the pump, then the control valve, then the cylinder. Each step has a warning about trapped air causing erratic load handling. That is safety stuff you do not get from a YouTube video.

Source Validity: Factory OEM vs. Aftermarket

Aftermarket manuals for the ATF 80-4 often copy the index but skip half the torque tables or substitute generic schematics. This manual is from Tadano FAUN GmbH – the same company that built the crane. It has the original FAUN part number (05379) and the After-Sales Service contact in Lauf a.d. Pegnitz. The 882 pages are original scans, not reprints. I have seen aftermarket manuals that omit the paint cure time warning on page 2 – and then a year later the boom rusts through. Do not trust a re-seller’s file when the factory one exists.

FAQ – Common Questions About the ATF 80-4 Service Manual

Does this manual include the engine removal procedure?

Yes. The engine chapter covers removal, installation, and torque specs for all fasteners. It also lists special tools required – like the engine sling adapter.

What about the hydraulic system?

The manual dedicates several sections to hydraulics: pump rebuild, valve body disassembly, cylinder seal replacement, and pressure testing. Page references are given for each subsystem. That is over 80 pages of hydraulic data.

Is this the same manual a Tadano dealer uses?

It is the exact same OEM document distributed to dealers and factory service centers. It even includes the original customer letter on page 2 about paint care and corrosion prevention.

How many pages does it have?

882 pages.
