Terex PPM AC35 Technical Manual

If you’ve ever chased a pressure drop in a Terex PPM AC35 transmission with a reprint manual that gives you 12 bar instead of 16+2, you know the feeling. That mismatch costs you time and a valve body. This Terex PPM AC35 Technical Manual is the original factory document – 144 pages of the same schematics and tables the assembly line used. No aftermarket interpretation, no translated errors.

Transmission and Clutch Data – Factory Pressure Tables

Page 4 of the manual lays out the clutch engagement table for forward, reverse, and neutral. Each clutch shaft – K1, K2, K3, KV, KR, K4 – has a dedicated solenoid and pressure regulator. The measuring points on the valve block are numbered 60, 55, 56, 53, 57, with specific pressure values: 16 +2 bar for most clutches, 13 bar before the converter, 3.5 bar behind it. These are the numbers you need to set your regulator. Page 5 gives the full control circuit diagram with the transmission pump output: 103 L/min at 2000 engine rpm and system pressure 16 ±2 bar. Without these factory specs, you’re guessing on a crane that doesn’t forgive guesswork.

Does This Manual Cover the Pneumatic Solenoids?

Yes. The bookmark section AC35PNEUMATIC SOLENOIDS is included inside the EVPNEUG.pdf file. It details the solenoid valves that control the pneumatically actuated clutches on the PPM AC35. If you’re troubleshooting a shift hesitation or a dropped gear, you need that specific pneumatic layout – generic wiring diagrams won’t match the Italian-built valve block. The sections AIRCIRCUIT.pdf and EVPNEUG.pdf work together to give you the complete air and electrical path.

144 Pages of Factory Specs – Why Originals Matter

This is not a third-party copy. The source file name is TerexPPM_AC35_Technical_Manual_fr-46613007908.pdf, scanned from the original Terex PPM binder. Every page is a direct reproduction, including the hand-drawn assembly diagrams and the original French text with numeric values. The Manual Transmission chapter alone contains 16 labeled clutch components and the power take‑off coaxial setup. When you compare aftermarket manuals to this, you’ll see where the aftermarket omitted the converter safety valve position (item 15 on the exploded view). That valve prevents over‑pressurization – skip it and you risk seal failure.

Read the Air Circuit Diagrams Before You Start

Start with AIRCIRCUIT.pdf. It shows the entire pneumatic logic from the compressor to the solenoid bank. The manual uses consistent numbering – the same pressure switch 36 (front axle) appears on the wiring chart and the air diagram. Cross‑referencing these two documents is the only way to confirm a failed switch versus a clogged line. A second external resource on Manual Transmission principles can help, but only this manual gives the exact port numbers for the telehandler’s clutch pack.

Telescope Section: What the Bookmark Shows

The TELESCOPE.pdf file contains 19fTel403r2.pdf and 19gTel403r34.pdf, both labeled TELES5. These pages cover the telescope cylinder extension sequence and the interlock switches. For crane owners who operate their own machine, the boom extension procedure is critical – the manual specifies the order of solenoid activation that prevents mechanical binding. Ignore that order and you bend the wear pads. The data in this section is the same design documentation used by Terex PPM service centers.

Who needs this manual? If you are a heavy‑equipment mechanic, a crane fleet owner, or a DIY operator who does his own PM and clutch adjustments, this is the reference that keeps you from drilling into the wrong port. The aftermarket manuals for this crane are sparse – most are retyped from the original and lose the coordinate grid on the valve block diagrams. This original keeps every M10x1 and M14x1.5 thread designation for the pressure measuring points.

Is this manual in English?

No, it is in French. The diagrams and numeric values are language‑independent.

How do I use the clutch pressure table on page 4?

Page 4 lists the engaged clutches for each driving direction and speed. The table columns show which solenoids (V1, V2, V4, V6) are energized and which clutch shafts (K1, K2, etc.) are active. The measuring points 55, 56, 57, 60 correspond to specific ports on the valve block. For example, when forward speed 1 is selected, clutch shaft K1 is engaged and pressure must be read at measuring point 56 (16+2 bar). The table also shows the pressure regulator under voltage for each gear – that tells you which solenoid should be drawing current. Cross‑reference that with the valve block circuit on page 5 to isolate a failed solenoid or stuck check valve. This is the only factory document that gives the exact port numbers – aftermarket diagrams often omit the M10x1 thread designation for the test ports.

You have the machine data. Now get the manual that makes it actionable. Access the Factory Manual and put it on your tablet next to the crane – your transmission will thank you.
