Description
Same Laser 110 130 150 Tractor Workshop Manual is the factory technical publication for workshop repair, dismantling, inspection, adjustment and reassembly of the principal transmission, axle, steering, braking, hydraulic, cab and electrical systems fitted to the SAME Laser 110, Laser 130 and Laser 150 tractors.
This 439-page manual is intended for agricultural engineers, tractor repair specialists, fleet workshops and experienced owners carrying out major mechanical work. It provides illustrated component layouts and structured procedures covering removal, disassembly, checks, dimensional verification, installation and final adjustment. Technical data, prescribed clearances and tightening torques are included where required by the relevant repair operation.
The publication covers both the non-driven telescopic front axle used on two-wheel-drive tractors and the front driving axle installed on four-wheel-drive versions. It also extends through the rear axle, gearbox, gearbox lubrication circuit, clutch, power take-off clutch, hydrostatic steering, brakes, hydraulic lift, supplementary hydraulic services, cab equipment and electrical lighting system. This is a workshop manual rather than an operator handbook or parts catalogue.
GEARBOX, CLUTCH AND TRANSMISSION
The transmission chapters provide workshop information for separating, dismantling, checking and rebuilding the tractor’s clutch and gearbox assemblies. Procedures are arranged around the individual components and assemblies, helping the technician follow the correct dismantling sequence and carry out the required checks before reassembly.
Transmission-related subjects covered include:
- Gearbox clutch removal, inspection and installation
- Clutch components and associated operating parts

FRONT AXLE AND STEERING COMPONENTS
The front axle section includes the adjustable telescopic axle fitted in place of the driving axle on two-wheel-drive models. It describes the central axle, side axles, mounting pin, wheel shafts, hubs, steering tie rods and centrally positioned steering mechanism. Illustrated procedures show how the assembly is supported, disconnected, removed, examined and installed.
Front axle workshop procedures include:
- Complete front axle removal and installation
- Central axle bushes, mounting pin and shim inspection
- Power-steering unit removal and installation
- Steering tie-rod and ball-joint servicing
- Steering centre-lever removal and bearing inspection
- Wheel-hub dismantling, bearing replacement and reassembly
- Wheel-shaft, thrust-bearing, bush and seal servicing
- Front track-width variation and steering-rod positioning
- Toe-in measurement and correction
- Axle end-float measurement and shim adjustment
FRONT DRIVING AXLE
Four-wheel-drive tractors are covered by a separate front driving axle chapter. This section provides illustrated workshop information for the complete driven axle and its principal mountings, hubs and internal assemblies. The material is organised for technicians carrying out axle removal, component-level inspection and overhaul.
Front driving axle subjects include:
- Complete front driving axle assembly
- Axle removal and installation
- Rocking mountings and associated checks
- Hub dismantling and reassembly
- Hub pins, bearings, seals and related components
- Inspection for wear, scoring and mechanical damage
- Adjustment and assembly data
- Specified tightening torques and lubricant requirements
REAR AXLE, BRAKES, WHEELS AND TYRES
The manual continues with the rear axle and tractor braking system, supported by separate information for wheels and tyres. These chapters assist with dismantling, inspection and rebuilding of chassis and running-gear components rather than limiting the material to routine maintenance.
Coverage includes:
- Rear axle assembly and related components
- Removal, dismantling and installation procedures
- Bearing, shaft, seal and housing inspection
- Brake assembly servicing and adjustment
- Parking and service-brake related components
- Wheel removal and installation information
- Wheel and tyre specifications where provided
- Relevant checks, adjustments and tightening torques
HYDROSTATIC STEERING AND HYDRAULIC SYSTEMS
The hydrostatic steering section complements the mechanical front-axle procedures by covering the hydraulic steering assembly and its supporting circuit. The manual also includes the tractor’s lifting group and supplementary hydraulic circuit, providing repair information for hydraulic components used for implement control and auxiliary services.
Hydraulic and steering subjects include:
- Hydrostatic steering circuit and component arrangement
- Power-steering housing servicing
- Hydraulic hose and union disconnection
- Steering system oil restoration and bleeding
- Hydraulic lifting group components
- Lift mechanism inspection and repair
- Supplementary hydraulic circuit components
- Hydraulic checks, adjustments and service data
CAB AND ELECTRICAL LIGHTING
Workshop coverage is also provided for the complete cab and the electrical lighting equipment. These sections support removal and repair work involving the operator’s enclosure, access components, controls and lighting circuits fitted to the covered tractors.
Cab and electrical coverage includes:
- Complete cab assembly
- Cab removal and installation information
- Doors and associated cab fittings
- Dashboard and instrument-area components
- Operator’s seat and mounting components
- Electrical lighting circuits and equipment
- Electrical component inspection and connection information
- Relevant diagrams and technical specifications
TESTING AND ADJUSTMENT
Testing and adjustment instructions are incorporated into the individual system chapters so that repaired assemblies can be checked before the tractor is returned to service. The front axle material, for example, specifies procedures for measuring wheel toe-in, axle end-float, steering-joint position, bearing condition and component play.
Typical workshop checks include:
- Visual checks for cracks, deformation, corrosion and scoring
- Bearing inspection for noise, vibration and seizure
- Bush and pin wear assessment
- Ball-joint movement and protective-boot inspection
- Wheel-hub axial-play measurement
- Front axle end-float measurement and shimming
- Wheel toe-in measurement and tie-rod correction
- Application of model-specific tightening torques
- Lubrication and hydraulic-system bleeding after assembly
TROUBLESHOOTING AND REPAIR
Fault-finding tables link reported symptoms with probable causes and suitable corrective action. These are used alongside the dismantling and inspection procedures to help distinguish adjustment or lubrication faults from worn bearings, joints or other damaged components.
Troubleshooting information includes:
- Abnormal axle or hub noise while travelling
- Insufficient lubrication at hubs, pins or axle bushes
- Worn axle and hub bearings
- Excessive front axle end-float
- Loose side-axle retaining hardware
- Wheel oscillation and tyre-related faults
- Worn steering ball joints
- Specified corrective repair or adjustment actions

This manual is particularly useful where a repair requires more than routine servicing information. The illustrated sequences identify the order in which assemblies are removed and stripped, while the accompanying checks explain what should be inspected before reusable components are installed again.
It should be used with the identification and specification of the tractor being repaired, especially where production changes or alternative equipment may affect the exact assembly fitted. For workshops maintaining SAME Laser tractors, it provides a substantial technical reference for transmission, axle, steering, brake, hydraulic, cab and electrical repair work.
