The fault-finding table for the brake system, hydraulic system, and torque converter-power shift transmission helps you diagnose problems fast, and the system drawings provide the hydraulic and electrical schematics you need when troubleshooting or repairing.

Technical Data and Specifications

The technical data chapter lays out every measurable aspect of the MK-A15.1: main dimensions (8,318 mm length, 1,830 mm width, 2,555 mm height above driver’s canopy), body capacity of 7.5 m³ (SAE, heaped), deadweight of 14,100 kg and payload of 15,000 kg. You get front and rear axle loads unladen and laden, maximum tramming speeds in each of the four forward and four reverse gears in both converter and lock-up mode, and a maximum admissible gradient of 25%. The engine is fully documented as the DEUTZ F8L413FW air-cooled diesel with two-stage combustion, rated 115 kW (reduced) at 2300 min⁻¹, running a dry air filter and silencer with a 5.4 kW/24 V starter and a 28 V/50 A three-phase alternator. The travel drive unit is covered in detail: Clark CL 270 single-stage torque converter with auxiliary drives for steering and dump/hoist hydraulics, Clark R 32000 power shift transmission with four forward and four reverse gears, and Kessler D81PL488 rigid planetary axles with differential gear at both ends. Wheels and tyres are specified as 14.00-24 at 6.5 ± 0.1 bar. The braking system is a three-circuit hydraulic power brake with externally cooled multi-disk service brakes on all four wheels and a spring-operated, hydraulically released parking brake integrated in the power shift transmission. Steering is swivel-joint hydraulic power steering with a ±42° steering angle. The swivel hinge is a GHH/Rote Erde ball-bearing slewing-ring with ±10° swing angle. All filling volumes are listed: 280 l fuel, 150 l hydraulic oil, 20 l engine oil with filter, 29 l converter/power shift transmission circuit, 15 l front axle differential, 2 x 3 l front axle planetary, 15 l rear axle differential, 2 x 3 l rear axle planetary.

Maintenance and Service Information

The maintenance section of this GHH MK-A15.1 manual is thorough. It includes the list of lubricants and operating agents with ambient temperature ranges and specifications for engine oil, coolant, fuel, brake fluid, hydraulic oil, transmission oil, axle gear oil, and lubricating greases. The checklist chapters break down every service task by interval, from daily lubrication points through to the 2400-hour maintenance scope. For each procedure, the manual specifies the operating agents, quantities, dimensions, and test pressures. The brake system maintenance includes bleeding procedures for the hydro brake system, diaphragm accumulator gas preload pressure checks and corrections, in-line filter element changes, service brake disk wear checks with the exact measuring method and reference dimension, parking brake adjustment, and spring brake cylinder mechanical release. The hydraulic system chapter covers oil level checks, return filter replacement, hydraulic oil changes, venting procedures, and pressure tests for the steering and dump/hoist circuits. The converter-transmission chapter gives oil level check procedures at operating temperature (82–93°C), oil change steps, intake strainer cleaning, and oil filter element replacement. The axle chapter covers planetary and differential gear oil changes and level checks. The electrical equipment chapter covers battery maintenance, three-phase alternator service, circuit breakers, battery switch, external starter socket, lighting system, and electro-hydraulic gear shifting.

Safety and Operating Procedures

Safety is covered extensively, with general safety instructions, special safety instructions for combustion engines, and specific safety instructions for mining and tunnel construction vehicles and for dumpers. The safety marking drawings (909-4-064433 and 909-4-064434) show the exact location and content of every warning and functional label on the machine. The operating section covers engine starting and switch-off procedures, tramming operation with gear change points (1st→2nd at 3.5 km/h, 2nd→3rd at 7.0 km/h, 3rd→4th at 12.0 km/h), driving with engaged lock-up, downhill driving in converter and lock-up modes, towing procedures, dumping operations with body raise and lower control, winter operation preparations, and vehicle shutdown and storage procedures.

Diagnostics and Fault Finding

The fault-finding table in this GHH MK-A15.1 operating instructions manual is a practical diagnostic tool. It covers the brake system (service brake and parking brake), hydraulic system, and torque converter-power shift transmission. For each fault symptom, the table lists possible reasons and the corresponding remedy. Symptoms include insufficient braking effect, overbraking, parking brake overheating, noise in the hydraulic system, sluggish dump/hoist or steering movement, low hoisting or steering force, low clutch pressure, converter operating noisily, high converter oil temperature, transmission shifting problems, and vehicle not tramming with gear engaged. This section alone can save hours of diagnostic time.

System Drawings

The system drawings section includes the service brake schematic (909-1-060368 D), converter-transmission hydraulic system schematic (909-1-053385 C), steering-operating hydraulic system schematic (909-1-053358 F), and electrical equipment schematic (909-3-053391 L). Translation sheets accompany the brake and converter-transmission drawings, providing component names and measuring point data in both German and English. The measuring-point plan (page 3.5-19) shows the location of all control valves and test fittings for the steering, dump/hoist, and brake systems.

What This Manual Enables You to Do

With this GHH MK-A15.1 dump truck operating instructions manual, you can confidently operate vehicle 3418/27 through its full range of functions, perform all scheduled maintenance at the correct intervals, diagnose and troubleshoot brake, hydraulic, and transmission problems using the fault-finding table, adjust the parking brake, check and correct diaphragm accumulator gas preload pressure, service the torque converter and power shift transmission, maintain the axles and drivelines, and service the electrical system. The pressure test values, torque specifications, wear limits, and adjustment dimensions are all provided so you can work to the manufacturer’s tolerances rather than guessing. The step-by-step procedures for engine starting, tramming, downhill driving, lock-up engagement, dumping, and towing help you get the most from the machine while avoiding damage from improper operation. For underground mining and tunnelling operations, the safety instructions and specific guidelines for dumpers in confined spaces are essential reading.
