This Ammann ASC 70 Cummins Tier 3 single drum roller workshop manual is the full service documentation that a technician needs to safely strip, repair, reassemble and adjust the machine. Every chapter follows a removal-to-refit logic supported by labelled exploded views, photos of the actual components and dedicated fixture or special-tool references, so procedures stay traceable on the shop floor rather than in the abstract. It covers the complete drivetrain and attachment set including the travel and vibration hydrogenerators, drum-mounted hydraulic motors, articulated joint bearings, steering cylinders, ROPS frame, bonnet and cab lifting hydraulic motors, segment assembly for padfoot conversion, tyre and wheel removal, hydraulic oil filling, level gauge and fuel floater service, plus the electrical layout and fuse allocation. Diagnostics are handled with a dedicated fault-finding chapter, and the tightening torque tables covering metric threads, hose and fitting necks and plugs are included with the manual.

What This Workshop Manual Covers in Detail

Unlike a condensed service booklet, this Ammann ASC 70 workshop manual is organised so that each major group can be disassembled and rebuilt independently. The engine removal chapter describes the complete sequence of hood lifting, radiator removal, filter and muffler extraction, wiring disconnection, cab lifting and engine extraction onto support, referencing the fixture numbers used at each step. The drum dismounting chapter walks through frame support, hydraulic motor removal, crossbeam removal, rubber mounting slackening, spacer removal and rolling the drum out, and includes the vibrator plate and vibrator rebuild with bearing and seal installation, nut torque values, Loctite specification for the hydraulic motor bolts and the axial play check. The articulated joint chapter documents bearing removal and installation, pin pressing with the correct fixture, and the tightening sequence with torque values for the cover and flange bolts.

Hydraulic content is spread across several chapters: removal of pumps, steering cylinders, hydraulic motors for the hood and cab, hydraulic system diagram with legend, and the diagnostics chapter with standard and optional test spots, maximum pressures for forward, backward, vibration I and II, steering and feed circuits, plus vibration frequency adjustment on the vibration pump. Torque and hydraulic fitting tables are gathered in a dedicated chapter so that every bolted and threaded connection can be verified against the printed values.

Electrical and Safety Content

The electrical installation chapter identifies the fuse block layout with fuse ratings F1 to F12 and their protected circuits, the master switch procedure with the 30-second rule after ignition key removal, the battery charging and dismounting rules, alternator notes, starter notes, and a labelled electrical wiring location diagram covering the machine sensors, switches, valves and connectors. A wiring schematic covering the seat switch Tier III configuration with 4x ATC is included with the component key list. Safety content runs through the manual, including the repair safety instructions covering hydraulic circuits, fuel systems, electrical wiring, welding on the machine, seals, environmental measures, hygiene and fire precautions, plus a chapter of standard hand signals for guiding the machine.

Who This Manual Is For

This Ammann ASC 70 service manual suits independent workshops, fleet maintenance teams, dealer technicians and owners who service their own single drum roller and need the factory procedure and torque values rather than a generic best guess. The procedures assume trained, skilled personnel and reference special tools and fixtures where required, so the reader should have access to a hydraulic press, lifting equipment and torque wrenches. Values and procedures apply to the ASC 70 in D, PD, HD, HDPD, HT, HTPD and PDB configurations with the Cummins Tier 3 engine, from Serial No. 2742050.

Why This Manual Matters

Drum vibrators, articulated joint bearings and travel hydrogenerators are expensive components, and incorrect disassembly or a wrong tightening torque on the vibrator plate nut or the bearing cover bolts can turn a routine service into a major repair. Having the real Ammann procedure, the fixture numbers, the Loctite specifications and the actual torque values in hand means the job is done once, done right, and with the machine back on site sooner. The diagnostic test spot values let you confirm whether a hydraulic fault lies in the travel, vibration or steering circuit before parts are ordered, and the vibration frequency adjustment table keeps the drum running at the specified 30 Hz and 41 Hz.
