Beyond the chapter list, the document works as a complete workshop reference for one machine rather than a general overview. The repair sections go down to individual bearings, seals, circlips and spacer rings, with assembly sequences, heating and cooling temperatures for bearing races, grease and sealant call-outs, and stated tightening torques for the critical joints on the exciter housing, flanged hub, side plate and clamping ring. The hydraulic chapters walk through the Sauer travel and vibration pump tandem unit, the drum and axle drive motors, the charge and flushing circuits and the steering valve, and they are backed by measurable test points with nominal charge, high-pressure and steering pressures. The electrical half of the manual links the ESX travel control, MESX measuring control, data collector and LC display together, lists ESX and EMR3 fault codes with possible causes, and finishes with the E-Plan and Caddy wiring diagrams plus a full component listing and terminal strip overview.

What This Manual Lets You Do

With the BOMAG BW 226 DH-4 BVC Single Drum Roller Service Manual on hand you can carry out the work the machine actually demands: setting the travel pump neutral position, teaching the electronic steering end stops, reading and clearing ESX and engine fault logs, measuring charge pressure and high-pressure override in the travel and vibration circuits, flushing and bleeding the closed loops after a component change, and verifying vibration motor leakage against the permitted rate. On the mechanical side it supports drum removal, exciter unit dismantling and rebuild, rubber buffer replacement with pretension adjustment, oscillating articulated joint overhaul, and the removal and resealing of the cab window panes.

Correct procedures and the specified values matter here. A hydrostatic roller is unforgiving of a wrong torque, an unbled circuit or a mis-set neutral position, and the service manual supplies the sequence, the measuring points and the nominal figures that keep the machine within its design limits instead of relying on trial and error. Deutz TCD 2012 L06 2V engine maintenance, from valve clearance and ribbed V-belt checks through to Common Rail fuel filter changes and water separator cleaning, is documented with the same level of detail.
