Frame, Joint and Protective Structure Coverage

The manual starts with the A45G FS frame arrangement and explains how the tractor unit and load unit are connected through the frame joint. It describes the tractor unit frame, load unit frame, axle mounting points, Full Suspension cylinder brackets, cross-stay and torsion-bar locations, and the underbody skid-plate system that protects the engine and transmission area.

Protective plate coverage goes beyond identification. The manual provides component weights and full procedures for removing and installing the front skid plate, left and right underbody plates, front and rear cross members, with the lifting equipment and fixtures identified in the procedure. This makes the manual useful when access beneath the machine requires the protective structure to be lowered or removed before other service work.

Full Suspension Hydraulic System

A major part of this Volvo A45G FS suspension service manual is devoted to the Full Suspension system. The system is described as an all-hydraulic arrangement using six double-acting hydraulic cylinders, accumulators, position sensors, pressure sensors, solenoid valves and a dedicated hydraulic pump. The manual explains normal, top and bottom suspension positions, rough and fine control, forced adjustment, signal handling and speed-limitation conditions.

Hydraulic circuit information covers how the tractor and trailer distribution blocks are supplied, how the suspension circuits are cross-connected for anti-roll action, and how high- and low-pressure accumulators work under unloaded and loaded conditions. Position sensor relationships and calibration references are also included, together with operating conditions for control requests and alarm displays.

Testing, Pressure Checks and Troubleshooting

The Volvo A45G FS Frame and Full Suspension Service Information Manual PDF includes practical checks used to verify suspension performance. Tech Tool operations listed in the manual include hydraulic suspension checking, position sensor checking and hydraulic suspension calibration. The service procedures cover complete depressurization, forced raising and lowering, manual lowering when the engine is not working but electronics remain functional, hydraulic pump maximum-pressure checking and adjustment, and hydraulic suspension bleeding.

IMAGES PREVIEW

The function-check procedure is especially useful for diagnosis. It guides the technician through checking for external leakage, abnormal pump noise, position sensor values, pressure levels in normal, top and bottom positions, accumulator precharge response and symptoms of internal leakage. Additional troubleshooting covers leaking raise valves, leaking lowering valves and suspension cylinders with internal leakage, including procedures for isolating the affected side or cylinder.

Suspension Cylinders, Accumulators and Sensors

The manual provides detailed service information for suspension cylinders on both the tractor and trailer units. It includes cylinder overhauling, seal and guide-ring replacement, piston and piston-rod work, piston-rod guide removal and installation, bushing replacement and specified tightening references. Separate removal and installation procedures are provided for the front axle cylinder and front bogie axle cylinder.

Accumulator content includes precharge specifications, nitrogen charging precautions, checking and adjusting precharge pressure, tractor accumulator removal and installation, trailer accumulator-bank removal and installation, and high-pressure accumulator replacement on a removed bank. Position sensor procedures include complete sensor replacement, front sensor replacement, rear sensor replacement, linkage adjustment and calibration references.

Frame Joint, Hitch and Steering Joint Service

The frame-joint section is extensive. It describes the hitch, intermediate shaft, tapered roller bearings, drive flanges and parking-brake disc arrangement, followed by tightening data and lubrication requirements. Procedures cover separating and reassembling the machine at the frame joint, checking frame-joint bearings, replacing frame-joint bearings with the machine separated, removing and installing the hitch, replacing steering-joint bearings, and servicing steering-joint bearings with the hitch removed.

These procedures include lifting and support arrangements, jack and puller use, bearing heating and cooling instructions, seal and O-ring replacement, greasing, lock-nut installation and final torque references. The hitch weight, bearing service conditions and handling steps are stated where relevant in the manual.

Axle Suspension, A-Frames, Cross Stays and Wheels

Further sections explain the A-frame arrangement on the tractor and load unit, axle suspension design, cross stays and rubber bushings. The manual includes axle-suspension tightening data for both tractor and bogie locations, tractor A-frame bushing replacement, load-unit front and rear A-frame bushing replacement, cross-stay removal and installation, and cross-stay rubber-bushing replacement using a workshop press.

Wheel information covers tightening torque, wheel removal and installation, and wheel alignment. The alignment procedure includes checks for centering the front bogie axle and comparing rear bogie axle distances, with permitted differences and pad-adjustment guidance described in the manual.
