Below, the general prerequisites are explained first, followed by the standard installation procedures, precautions and safety specifications for 24V starter motors on Iveco and Volvo vehicles. Both models are mainly commercial diesel vehicles with a 24V electrical system. Their structures are similar but differ in details. Be sure to disconnect the power and verify the part model before installation.
I. General Preparation and Safety Requirements Before Installation
Verify Parts and Voltage
Only use a starter motor rated at 24V and compatible with the corresponding engine model. Check that the gear module, mounting hole positions, flange dimensions and wiring terminals are consistent. Do not use a 12V starter motor as a substitute.
Power Disconnection Procedure
First disconnect the negative terminal of the vehicle’s 24V battery, then the positive terminal, to prevent short circuits and wiring burnout during installation.
Tool Preparation
Socket wrenches, ring wrenches, a torque wrench, a brass brush, sandpaper, high-temperature anti-seize lubricant, insulating tape, cable ties, and sealant (as required).
Preparatory Treatment of the Original Part Location
If replacing the starter motor, remove the old unit first. Clean oil, rust, and carbon deposits from the flywheel housing mounting surface and bolt holes to ensure a flat and tight fit.
II. Standard Installation Procedure for Iveco 24V Starter Motors
Iveco commercial vehicles (Daily, Eurocargo, etc.) are mostly equipped with inline diesel engines. The starter motor is typically mounted on the right side of the engine, at the flywheel housing, mostly in a horizontal layout with two fixing bolts and a positioning pin.
1. Starter Motor Body Installation
Inspect the flywheel ring gear for broken or severely worn teeth. Any damage must be repaired first; otherwise, the starter drive gear will be damaged.Apply a small amount of high-temperature anti-seize lubricant to the starter flange sealing surface and the threads of the fixing bolts to prevent seizing due to rust and corrosion over time.Support the starter motor with both hands, align it with the positioning pin on the flywheel housing, and insert it smoothly. Ensure the drive gear meshes properly with the flywheel ring gear, with no jamming or misalignment.Install the fixing bolts, tighten them by hand first, then pre-tighten with a wrench, and finally fasten them to the standard torque specified in the service manual using a torque wrench.Common reference torque values (for on-site reference only; always follow the vehicle service manual):Approximately 110N·m for M10 bolts, and 160N·m for M12 bolts.Check that the starter motor is free of wobble and that the drive gear returns smoothly. The overrunning clutch should extend and retract freely when actuated manually.
2. Wiring Connection (24V System)
Iveco starter motors generally have two terminals: a high-current main power terminal and a control signal terminal.First connect the thick main power cable (from the positive terminal of the 24V battery main power supply), fit the insulating sheath, and tighten the nut to ensure it is secure and free from grounding.Then connect the thin starting control wire (from the ignition switch/starting relay), secure the plug or fasten the terminal, and apply proper insulation protection.Arrange and secure the wiring harness with cable ties, keeping it away from friction with the exhaust pipe, fan, and drive belt to prevent high-temperature aging, abrasion and short circuits.
3. Reassembly and Test Run
Reconnect the battery, connecting the positive terminal first, then the negative terminal.Turn on the ignition switch and attempt a short start. Do not crank continuously for an extended period (no more than 5 seconds per attempt, with an interval of at least 15 seconds).Observe the following: abnormal noise, slipping or free spinning of the starter motor, whether the engine can be cranked normally, and overheating or smoking at the wiring connections.After the test run, inspect the mounting bolts and wiring terminals for looseness, and check for oil leakage and abnormal noise.
III. Installation Procedure for Volvo Commercial Vehicle 24V Starter Motors
Volvo heavy commercial vehicles such as FM, FH and FE are mostly equipped with reduction-gear starter motors of higher power, with a more robust mounting structure. Some models are fitted with brackets and multiple fixing bolts. The wiring logic is identical to that of Iveco, but the fastening requirements are stricter.
1. Pre-Installation Inspection
Verify the Volvo engine model (D11, D12, D13, etc.), and confirm that the starter motor part number, rated voltage of 24V and reduction ratio are matched.Check that the flywheel housing mounting surface and positioning pin are intact, clean the bolt holes and remove impurities.Inspect the condition of the starter overrunning clutch, carbon brushes and commutator. New parts can be installed directly.
2. Body Installation
Apply anti-seize lubricant to the bolt threads and flange contact surface.Align with the positioning pin and push the starter motor horizontally into place, ensuring the drive gear fully engages the flywheel ring gear area with no interference.Tighten the fixing bolts in a diagonal sequence and in stages. Never fully tighten a single bolt at once, to avoid flange deformation and poor sealing.Strictly follow the torque values specified in the Volvo service manual. Heavy-duty engines require higher torque for large bolts; common references are:Approximately 180N·m for M12 bolts and 220N·m for M14 bolts. Always refer to official data.Rotate the engine flywheel manually to confirm no interference between the starter gear and the flywheel, and proper return of the gear.
3. Wiring Connection
Heavy-duty vehicles use thicker main cables. First fasten the 24V positive main power supply terminal, installing spring washers and flat washers to prevent loosening due to vibration.Connect the starting control signal wire. Some Volvo models are equipped with shielded wires and protective plugs, which must be fully locked to prevent water ingress and oxidation.Route the wiring harness away from high-temperature areas such as the turbocharger and exhaust pipe, and secure it firmly to avoid abrasion from vibration.
4. Testing and Acceptance
Restore the battery connections, positive terminal first, then negative.Perform a short idle start test and listen for abnormal noise or gear grinding.After a road test, recheck the bolt torque, wiring temperature, and any oil or electrical leakage.
IV. General Key Precautions (Must Read)
- Forcible striking during installation is strictly prohibitedThe starter motor contains carbon brushes, a commutator and reduction gears. Heavy striking will cause internal components to shift and become damaged. The starter must only be inserted smoothly and steadily.
- Torque must meet the specified standardCommercial vehicles experience severe vibration during operation. Loose bolts may result in cracking of the flywheel housing, detachment of the starter motor, and gear grinding failure. A torque wrench shall be prioritized for fastening.
- Incorrect wiring is strictly forbidden in 24V systemsReversing the positive and negative terminals, or mixing 12V and 24V components, will instantly burn out the starter solenoid switch and the vehicle body control module, leading to significant damage.
- Taboos during startup testingForcible cranking is strictly prohibited when there is no engine oil or the engine is seized. Each cranking duration shall be kept short to prevent overheating and burnout of the starter motor.
- Reliable grounding connectionThe starter motor relies on its housing for electrical grounding. The mounting surface must maintain metal-to-metal contact. Paint and rust must be removed to ensure qualified grounding resistance.
