Description

Ammann ASC 70-250 Single Drum Roller Workshop Manual

This Ammann ASC 70-250 Single Drum Roller Workshop Manual is the complete service and repair guide for the Ammann ASC series single drum rollers powered by Cummins Tier 1, Tier 2 and Tier 3 diesel engines. Published by Ammann Czech Republic a.s. in Edition 05/2010, the manual spans 368 pages and takes a technician through every major assembly of the machine – from removing the engine and dropping the drum, through the articulated joint, pumps, steering cylinders and hydraulic motors, to full electrical schematics and hydraulic circuit diagrams. Whether you are servicing an ASC 70, ASC 90, ASC 100, ASC 110, ASC 130, ASC 150, ASC 200 or ASC 250, this workshop manual gives you the procedures, torque figures and fluid capacities needed to do the job correctly.

The Ammann ASC workshop manual is written for the technician who needs to strip and rebuild the roller’s major groups, not just read about them. Engine removal is shown step-by-step with lifting fixtures and labelled photos. Drum removal and the vibrator assembly are covered in depth, including bearing pressing, seal fitting, nut torque and eccentric handling. The articulated joint section explains the cross-roller bearing and vertical pin arrangement used on ASC 70-150 and the single-pin layout used on ASC 200/250. Hydraulic pump and Cento clutch removal, steering cylinder seal replacement, and hydraulic motor removal are all documented with torque tables. Separate electrical schematic chapters cover Tier 1, Tier 2 and Tier 3 wiring looms, fuse boxes and pin-out legends, while the hydraulic chapter provides complete circuit diagrams for ASC 70/90, ASC 110/150 and ASC 200/250, including ATC inter-axle and inter-wheel differential lock variants.

What a Technician Gets from This Manual

Beyond the disassembly and assembly sequences, this Ammann ASC 70-250 Single Drum Roller Workshop Manual includes the reference material that keeps a repair accurate. The diagnostics chapter lists maximum pressure test values for travel, vibration and steering circuits on each model, along with adjustment procedures for the safety valve and vibration frequency. Fluid content tables give engine oil, coolant, fuel, hydraulic and gearbox capacities for every ASC model and Tier level. Weights, dimensions and turning radii are tabulated per model and variant (D, PD, PDB, HD, HT). The final tightening-torque chapter provides dry-thread torque charts for bolts, hydraulic hose caps, threaded necks and plugs, and a separate schedule for the segment mounting bolts with the follow-up re-check procedure. There is also a hand-signal chapter for jobsite communication and a dedicated engine troubleshooting table for no-start and slow-crank conditions.

Machine Variants and Engine Coverage

The manual documents the Ammann ASC series across smooth drum (D), padfoot (PD), padfoot with blade (PDB), and the HD and HT heavy-duty and mountain versions. Engine coverage includes the Cummins B3.9-C99, 4BTA 3.9-C116, B5.9-C148 and B5.9-C200 for Tier 1; the B4.5-C99, QSB5.9-C155 and QSB5.9-C205 for Tier 2; and the QSB3.3-C99, QSB4.5-C160 and QSB5.7-C220 for Tier 3. Serial-number ranges are given for each model where the manual content changes, so you can confirm whether the procedures in a given chapter match your machine before you start work.

Why This Workshop Manual Matters

Roller repairs go wrong when torque values are guessed, hydraulic circuits are opened under pressure, or the wrong bearing preload is set. This Ammann ASC workshop manual removes that guesswork. It tells you which fixtures to use for hood, cabin, drum and engine handling, where to plug and cap hydraulic openings, how to heat bearings and hubs before pressing, how to set axial play on the vibrator bearings, and how to release the brakes for towing when the machine cannot be started. For a machine that is expected to compact to specification day after day, having the correct bearing preload, hydraulic pressure and bolt torque is the difference between a repair that holds and one that comes back.
