Liebherr 2plus2 Transmission Repair Manual – Wheel Loader L544 to L586 Overhaul Guide

This Liebherr 2plus2 Transmission Repair Manual is the complete overhaul and rebuild guide for the 2plus2 transmission used across the Liebherr wheel loader range from L544 to L586. Issued as document number 10011107, version 01, dated 12/02/03, and prepared by Liebherr-Werk Bischofshofen GMBH, it is written for maintenance personnel carrying out repair and rebuild work on the transmission. The manual walks through the entire process in order: safety procedures, cleaning and inspection of components, disassembly of the casing and each clutch pack, reassembly, and pre-operational checks after overhaul. It also carries the tightening torque tables, sectional drawings, exploded parts views and special tool drawings required to complete the job correctly.

The Liebherr 2plus2 Transmission Repair Manual is built around the complete teardown and rebuild of the transmission, not just routine servicing. Each clutch pack – 1st, 2nd and 3rd – has its own dedicated disassembly and reassembly section with step-by-step procedures, clutch pack clearance limits, and notes on the piston return spring sets that must stay matched by compression weight. The casing chapters cover removing the output flanges, pulling the driven gears and bearings, and separating the transmission casing from the motor casing. The technical data chapter carries the general transmission dimensions and dry weight, a version history table showing the running changes made to the transmission, and four separate tightening torque tables for bolts and A/C screws, ED plugs, L-type and S-type pipe couplings.

What This Manual Enables You To Do

With this Liebherr 2plus2 Transmission Repair Manual on hand you can strip the transmission down to bare components, identify wear on bearings, gears, shafts and housings, replace oil seals, O-rings, gaskets and snap rings, and build the unit back up with the correct clutch pack clearances. The sectional drawing and exploded views give a clear view of how the clutch shafts, drive gears, driven gears, output shaft, control valve, accumulator and filter assembly go together, so you can trace oil flow and hydraulic control routes before you touch a spanner. The torque tables let you tighten every fastener to the value Liebherr specifies rather than guessing, which matters most on the flange nuts, gear-retaining nut and control valve bolts.

The manual also covers the pre-operational inspection that has to be done before the transmission goes back into the machine: draining and flushing the system, cleaning the oil cooler, replacing the filter, and testing the accumulator pre-charge with a pressure gauge or two-channel writer. The accumulator nitrogen-filling procedure is included as well, with the target value shown so you can verify or top up the charge correctly.

Because the same manual spans the L544, L550, L554, L556, L564, L566, L574, L576, L580 and L586 wheel loaders, it is useful across a fleet rather than a single machine. The version and change table shows which modifications apply from which serial number onwards, so you can confirm that the steps you are reading match the transmission actually in front of you.
