Wacker Neuson ET35 EZ36 Track Excavator Service Manual (E16-01, E16-02) – Tier III & Tier IV PDF

Description

Wacker Neuson ET35 & EZ36 Track Excavator Service Manual – E16-01 / E16-02

This is the full workshop service manual for the Wacker Neuson ET35 and EZ36 track excavators, issued for vehicle types E16-01 (ET35) and E16-02 (EZ36). The document covers both Tier III and Tier IV machine variants in a single volume, so hydraulic, electrical, engine and maintenance procedures for either exhaust-gas standard are available without switching between books. It is written for the technician working on the machine rather than for the operator, and it is the reference used to set pressures, torque fasteners, diagnose faults and carry out scheduled servicing.

What the ET35 and EZ36 Service Manual Gives You

Because the ET35 and EZ36 share a platform but differ in travel gear, tail swing and a number of dimensions, this service manual handles both machines side by side. Technical data tables list values for the ET35 and EZ36 separately, so digging depth, transport length, tail end swiveling radius, track width and operating weight are read off the correct column rather than assumed. The same applies to ground pressure and the VDS travel gear variants, which carry their own dimension rows.

The maintenance chapter forms the practical backbone of the book. It sets out a maintenance plan that runs from daily checks through 50-hour, 500-hour, 1000-hour, 1500-hour, 2000-hour and 3000-hour intervals, with each task marked as operator or Wacker Neuson service center work. Fluids and lubricants are specified by application with capacities, including engine oil, coolant, hydraulic oil, gearbox oil, grease and washer fluid, plus ambient temperature ranges and viscosity classes. The procedure pages that follow show how to park the machine, open the engine cover, remove the tank room cover, reach the main and cabin fuse boxes, raise and lower the cab, and carry out lubrication on the boom, dozer blade, live ring teeth and bearings, cab hinges and control lever base.

Engine coverage splits cleanly between the two exhaust-gas standards. The Tier III machine runs the Yanmar 3TNV88-BPWN with mechanical engine management, while the Tier IV machine uses the 3TNV88F-EPWN with electronic control, EGR and a different fuel system layout. The service manual gives each its own compartment overview illustration so the fuel filter, prefilter with water separator, engine oil filter, dipstick, filler inlets, EGR valve and engine control unit can be located without guesswork.

Hydraulics, Electrical and Diagnostics

The hydraulic section identifies every major component by its equipment identifier – C001 main control block, T003 work pump, C006 control oil unit, T015 swivel unit, L042 hydraulic oil tank, L017 swivel joint, C017 quickhitch valve, C045 floating position valve and so on – and then explains what each does. Pump connections P1 through P4, service pressures, pilot control pressure, secondary pressure limiting valves and the drive counterbalancing system are all described, and the auxiliary hydraulics performance measurement section provides flow-versus-pressure tables so the pump output can be tested against real figures rather than judged by feel.

The electrical chapters are unusually detailed for a machine of this size. Sensors, controllers, relays and the CAN bus are introduced with resistance values for the terminal resistors, and the wiring harness section then breaks each harness down by strand number, cross-section, color code and signal name. The hydraulic diagrams, option diagrams and full circuit diagrams in chapter 9 close the loop by tying the components back to their connections.

Chapter 12 lists the SPN diagnosis codes together with the BMK designations for sensors, switches, solenoids, relays, controllers and indicating instruments, so a fault shown on the display can be traced to the component that produced it.

Who This Manual Suits

This service manual is aimed at the technician or workshop carrying out scheduled maintenance, hydraulic pressure setting, electrical fault finding, engine servicing or major component replacement on an ET35 or EZ36. Owners who do their own maintenance will also find the fluid specifications, capacities, tightening torques, track tension values, wear limits and maintenance intervals directly usable. The wear limit tables cover pins and bushings for every cylinder, the swiveling console, boom, shovel arm, bucket and stabilizer blade, together with lifting eye and tie-down point tolerances.
