Hydraulic System and Components

The hydraulic section of this Hidromek HMK102B HMK102S manual covers the complete hydraulic architecture, including the 120-liter hydraulic tank, suction and return filters, and the ISO VG 46 oil requirements. You will find detailed specifications for the tandem hydraulic pumps, including P1 displacement (37 cc/rev) and P2 displacement (29 cc/rev). The manual outlines the four available hydraulic circuit options—Standard Arm, Telescopic Arm, Standard Arm with Breaker, and Telescopic Arm with Breaker. It provides an in-depth breakdown of the steering priority valve, detailing how the LS (Load Sensing) system maintains steering function, as well as the operation of the Husco loader and backhoe valve blocks. You will also find the procedures for testing pressures, such as the main relief valve settings (230 bar for P1, 210 bar for P2) and the unloader valve.

Transmission and Drivetrain

Detailed chapters are dedicated to the torque converter and the ITL PS 760 Power Shift Transmission. The manual explains the hydrodynamic principles of the torque converter, including the function of the stator and turbine, and how it drives the transmission oil pump. For the transmission, the manual breaks down the seven hydraulic clutches (T, U, W, V, Y, Z, S) and provides solenoid activation charts for every forward and reverse gear. It covers the 4×4 clutch operation, which is automatically engaged in first and second gears but disengaged in third and fourth. Diagnostic pressure testing for the transmission is thoroughly outlined, including specific values for clutch pressure (13.4 bar) and torque converter input pressures at varying temperatures and RPMs.

Axles, Brakes, and Steering

Rebuilding and adjusting the front and rear axles is made straightforward with the step-by-step procedures for pinion depth, bearing preload, and crown gear backlash. The manual includes the shim calculation formula (31.19 – X) and the required torque values for the pinion nut. Two brake systems are covered: the Carlisle brake booster system and the Rexroth accumulator system. You will find bleeding procedures, pressure testing values, and component breakdowns for both. Finally, the steering section covers the 4WS / 2WD, 4-Wheel Drive, and Crab steering modes, explaining the solenoid logic (SV1-S1, SV2, SV3) and the proximity switch calibration required for safe mode changes.

Why You Need This Manual

Working on heavy equipment like the Hidromek HMK102B and HMK102S requires precise technical data.
