Installation Method for MAN 24V Starter (Original Factory Specification Version)
Applicable Models: 24V DC starters for MAN commercial vehicles, engineering machinery, marine vessels and generator sets, matched with D08, D28, D26 and MC series diesel engines, and adapted to original factory starters supplied by Bosch/DENSO. All torque, wiring and safety specifications comply with MAN Original Factory Service Manual (FSM) and Technical Service Bulletin (TSB).
Core Premises
The voltage class is strictly 24V; mixing of 12V starters and power supply systems is prohibited.
The starter power, number of teeth and mounting spigot are fully matched with the engine flywheel housing. Common power ratings range from 4.5–7.5kW, and the drive gear mostly has 11–12 teeth.
Fixing bolts shall be 10.9/12.9 grade high-strength bolts; replacement with ordinary bolts is prohibited. Wiring harnesses, terminals and insulating sleeves shall be intact without aging or damage.
I. Pre-installation Preparation (Safety + Tools + Inspection)
1. Safety Operations (MAN Mandatory Specifications)
Disconnect the main battery switch, or remove the negative cable first and then the positive cable to prevent short-circuit sparking of wrenches.Lock the vehicle parking brake, set the gearbox to neutral/P position, ensure the engine is completely cold, and take measures to prevent rolling and accidental starting.Ensure good ventilation in the operation area and keep away from flammables. The short-circuit current of the 24V system is large, and bare wire lap joint is strictly prohibited.
2. Tool List
Socket set: 13/16/18/19mm, universal joint, extension rodTorque wrench (0–200N·m), torque marking penCopper brush, sandpaper, insulating cleaning paste, high-temperature resistant lithium-based greaseMultimeter (for continuity/resistance measurement), open-ended/box-end wrenches, insulating gloves
3. Component Pre-inspection and Pre-treatment
Starter inspection: The drive gear (one-way clutch) telescopes smoothly without jamming or chipping; the solenoid switch engages normally; terminals are free of oxidation, ablation and cracks; armature splines are free of rust and deformation.Mounting surface inspection: The engine flywheel housing mounting surface is free of oil, rust and deformation; locating pins are intact without bending; locating holes are free of burrs and carbon deposits.Pre-lubrication: Apply a thin coat of high-temperature resistant grease to the armature spline shaft; excessive application is prohibited to avoid grease being thrown into the flywheel ring gear causing slipping and abnormal noise.Wiring harness inspection: The cross-sectional area of the 24V main power cable is ≥25mm², and that of the control cable is ≥4mm². The wire core is not exposed, the insulation is free of cracking, and the connectors are free of oxidation.
II. In-situ Installation Steps (Engine Not Lifted, Universal Process)
Step 1: Starter Positioning and Centering
Starter mounting position: Starters for MAN engines are mostly arranged at the joint of the engine and gearbox (flywheel housing), on the left or right side depending on the model, subject to centering by locating pins.Fit the starter to the mounting surface, and ensure the two locating pins are fully seated to guarantee concentricity of the drive gear and flywheel ring gear, eliminating gear chipping and poor meshing caused by misalignment.Insert the main fixing bolts (usually 2–3 pieces, M10–M14 specification), screw them to the bottom by hand without tightening temporarily, reserve fine adjustment allowance, and confirm the mounting surface is fully fitted with zero clearance.
Step 2: Tighten Main Bolts Diagonally According to Torque (MAN Original Factory Standard)
Adopt diagonal cross step-by-step tightening; single-bolt one-time tightening is strictly prohibited to prevent housing deformation and positioning offset.
| Engine Series | Main Fixing Bolt Specification | Tightening Torque |
|---|---|---|
| D08 Series (Light and Medium) | M10×1.25 | 45±5 N·m |
| MC11/MC13 Series (Heavy Duty Truck) | M12×1.5 | 110±10 N·m |
| D28 Series (Marine/Power Generation) | M12/M14 | 55–65 N·m |
| Universal Matching Model | M10 | 40–50 N·m |
After tightening:
Shake the starter by hand to confirm no looseness or movement;
Mark the alignment between the bolt head and the housing with a torque marking pen for subsequent spot inspection.
Step 3: Electrical Wiring (24V Special, Sequence Strictly Non-reversible)
MAN 24V starters uniformly adopt terminal definitions of 30# (main power), 50# (signal) and 31# (ground) with bipolar insulation design, and wiring must be standardized.
(1) Connect 30# Main Power Terminal (Thick Cable, 24V+)
Connect to the main positive cable of the battery, install flat washers + spring washers, and the tightening torque of bolts/nuts is 18±3 N·m.Arrange the wiring harness to avoid high-temperature exhaust pipes and moving parts, reserve buffer allowance, and strictly prohibit pulling and squeezing the root of the terminal to prevent pole cracking.
(2) Connect 50# Signal Control Cable (Thin Cable, Start Trigger)
Connect to the control cable of the ignition switch/start relay with a tightening torque of 8±2 N·m; apply moderate force and prohibit over-tightening to avoid terminal breakage.
(3) Ground (31#) Specifications
Marine/power generation models: Connect the special negative cable directly to the 31# pole; using the hull or frame as the ground is strictly prohibited.Vehicle-mounted models: The metal fit of the starter mounting surface serves as the main ground. If there is paint on the mounting surface, it must be sanded to bare metal, with the ground resistance ＜0.5Ω.
Step 4: Peripheral Interference Recheck and Reset
Check that the clearance between the starter and surrounding components (oil pan, exhaust pipe, heat dissipation pipeline, guard plate, etc.) is ≥5mm without friction or extrusion.Arrange the wiring harness, fix it with cable ties, keep it away from high-temperature and rotating parts, and ensure the insulating sleeve is intact.Install the positive battery cable first, and the negative cable last with a tightening torque of 12±2 N·m. Clean the oxide layer on the poles and apply conductive protective grease.
Core Installation Precautions for MAN 24V Starter
These precautions comply with the specifications of the MAN Original Factory Service Manual (FSM) and Global Technical Service Bulletin (TSB), covering five core dimensions: safety operations, mechanical installation, electrical connection, model-specific prohibitions, and fault protection. They apply to 24V starters matched with MAN D08/D26/D28/MC series engines, and are mandatory requirements to prevent starter burnout, gear chipping and starting failure after installation.
I. General Safety Operation Precautions 「Exclusive to 24V System, MAN Mandatory Specifications」
Keep the main battery switch disconnected / positive and negative cables removed throughout the operation. The short-circuit current of the 24V system is much higher than that of the 12V system; it is strictly forbidden for tools to contact the positive and negative terminals at the same time to prevent sparking, wiring harness ablation and even battery explosion.
Vehicles/equipment must be double-secured during operation: parking brake locked + wheel chocks in place, gearbox set to neutral/P position, and engine cooled down (temperature ≤40℃). Installation on a hot or unsecured engine is strictly prohibited.
Operation near flammables is forbidden, and the installation area must be well-ventilated. Testing the starter with bare wire lap joints is not allowed; all tests must be performed via a standard ignition switch/start relay.
