Terexlift TELELIFT 3713, TELELIFT 3517, TELELIFT 4010 2003 Workshop Manual

You’ve got a TELELIFT 3713 in the bay, and the boom won’t extend. You check voltage at the solenoid – good. You swap the relay – no change. Now you’re reaching for a generic aftermarket PDF that says “hydraulic system” in the title but gives you a diagram from a different model. That’s wasted time and a safety risk. I’ve been turning wrenches since the 90s, and I can tell you: when you’re dealing with telescopic handlers, the difference between a good repair and a comeback often comes down to one spec – the OEM torque value on a boom pivot bolt, or the correct pressure setting for the load-sensing pump. That’s why the Terexlift TELELIFT 3713, TELELIFT 3517, TELELIFT 4010 2003 Workshop Manual belongs on your bench, not a digital folder you ignore.

TELELIFT 3713, 3517, and 4010 Systems Covered

This Workshop Manual is drawn up by Terexlift’s own technical office. It’s the same binder that dealers used when the machines were new. The index on page 1 lists all three models: TELELIFT 3713, TELELIFT 3517, and TELELIFT 4010. That means one book covers the entire series. If you’ve got a 3713 Elite and a 3517 in the same fleet, you don’t need two separate manuals. The procedures for engine, transmission, hydraulics, and electrical systems are written for each variant. Need the charge pressure for the 4010? Flip to the hydraulics section. Need the boom cylinder rebuild sequence for the 3517? It’s in the same chapter. No flipping between different books – just one 772-page source.

What Torque Values Are Inside?

You’re torquing the wheel nuts on a 3713. Aftermarket manual says “tighten to spec” – which spec? Factory spec is on page [DATA NEEDED]. The manual lists every fastener torque in imperial units: wheel nuts, hydraulic fitting nuts, engine mount bolts, boom pivot pins. For the Manual Transmission section, you get the exact sequence for clutch housing bolts and output flange nuts. If you skip the torque table and guess, you’ll either strip threads or leave a bolt loose enough to shear under load. I’ve seen both. This book gives you the number, the sequence, and the angle (if required). No ambiguity.

Safety Warning: OEM vs Aftermarket Manuals

Aftermarket documentation for telescopic handlers is often a photocopy of a photocopy, with torque values converted wrong or missing entirely. Terexlift’s original edition (code 57.4400.5200, first edition 04/2003) comes with a declaration page – page 3 – that binds the recipient to use it only in their workshop and not share it with unauthorized shops. That’s how serious Terexlift is about safety. The wiring diagrams are specific to the 3713, 3517, and 4010 harness layouts. An aftermarket “universal” diagram can short a CAN bus line or bypass a safety interlock. This manual’s schematics are verified against production vehicles. Use them, not a copy from a forum.

772 Pages of Factory Procedures

The manual is 772 pages thick. That’s not fluff – it’s step-by-step disassembly, inspection limits, and reassembly for every major system: engine, hydrostatic transmission, drive axles, boom structure, hydraulic pumps, control valves, electrical panels, and cab controls. The section on the Manual Transmission (if your unit has one) includes shift fork tolerances and synchronizer ring wear limits. The hydraulic chapter gives you pump flow test procedures and relief valve adjustment specs. Beginners will appreciate the required tool lists printed at the start of each major repair. Professionals will use the troubleshooting charts to isolate faults without swapping parts blindly. Every page is from the factory – no rewrites, no third-party paraphrasing.

Understand the Wiring Before You Touch It

Electrical gremlins on telescopic handlers are common – broken wires in the boom harness, corroded connectors at the chassis junction. The workshop manual includes full color wiring diagrams for each model. You get connector pinouts, wire gauge, and splice locations. For the 4010, there’s a specific note about the boom extend limit switch circuit. If you misread it, you could override the safety cutoff and cause a cylinder over‑travel. That’s a shop‑lifting hazard. The manual’s electrical section is written for a tech who reads schematics – but even a beginner can follow the tracing instructions if they take it slow.

Need to dig into the hydraulic pump? The manual tells you which test ports to use, what pressure range to expect (in psi), and what to do if the reading is low. Page [DATA NEEDED] has the flow chart for the load‑sensing system. That kind of data keeps you from replacing a $2,000 pump when you only needed to clean the suction screen.

Q: Does this manual cover the TELELIFT 4010 with the optional boom rotation?

A: It covers the standard 4010 configuration. Boom rotation components are included in the hydraulics section, but verify your serial number against the manual’s applicability note on page [DATA NEEDED].

Q: Are the torque values in foot‑pounds or inch‑pounds?

A: All fastener torques are in foot‑pounds (ft·lb). A few small fasteners under 10 ft·lb are given in inch‑pounds where applicable. The conversion is printed on the spec sheet. Use a calibrated wrench – don’t guess.

Don’t waste another afternoon chasing a problem with a generic PDF that leaves out half the steps. Get the actual factory data that the Terexlift techs used when these machines were new. Access the Factory Manual from AutoRepairManuals and put it on your tablet or print it for the bench. Your TELELIFT 3713, 3517, or 4010 will thank you with fewer comebacks and more uptime.
