You may also find the following tools and materials useful:
- π οΈ Set of sockets with extensions and universal joint
- π οΈ Pliers and screwdrivers (phillips and flat) for detaching chips
- π οΈ WD-40 or penetrating lubricant for treating soured bolts
- π οΈ Clean rags and gloves to protect your hands from dirt and oil
## Disabling the electrical system and removing interfering elements
The first step in the removal procedure is to disconnect all electrical connectors connected to the starter. Usually there are two of them: a power wire from the battery and a control wire from the ignition switch. The power wire is secured with a nut on 13 or 12 mm, depending on the configuration. The control wire has a plastic chip, which must be carefully snapped off by pressing the latch.
Sometimes access to the starter can be difficult due to suspension components or the air intake. In some cases, for more convenient work it is necessary to remove the air filter and the pipe going to the throttle valve. This will free up some space and allow you to better see the fasteners. Don't forget to mark the location of the pipes in advance if you have to remove them completely.
It is important to inspect the condition of the wires before disconnecting them. If the insulation is damaged or the contacts are oxidized, this may cause further failure.
- π« Inspect the power cable for cracks and signs of overheating
- π« Check the integrity of the plastic starter housing
- π« Clean the connection area from dirt and rust with a brush
## Fixing the vehicle and accessing the starter mount
To carry out work comfortably, it is recommended to lift the car on a lift or use reliable stands. Nissan Almera Classic It has a fairly high ground clearance, but access from below to the starter is much more convenient than from above. The starter is secured with three bolts: two upper and one lower. The bottom bolt is often hidden behind a bracket or other suspension components, requiring the use of a special extension.
If you are working from below, be sure to place a block of wood under the engine to prevent damage to the oil pan if the engine is accidentally moved. The mounting bolts can be over-tightened, so use a wrench with sufficient leverage. Before unscrewing, generously coat the threads with penetrating lubricant and allow it time to work.
- Extension cord
- Cardan
- Head
- Ratchet
## Step-by-step process for removing mounting bolts
The process of unscrewing bolts requires consistency. The bottom bolt is unscrewed first, since it holds the main load when removing the unit. Then move on to the top bolts. Be careful: after unscrewing the last bolt, the starter may move abruptly, so hold it with your hand. Make sure there are no tools on hand that could fall into the engine compartment.
When unscrewing bolts, pay attention to the condition of the threads. If the threads are stripped or the bolt is stuck, do not use excessive force to avoid breaking the head. In this case, it may be necessary to use an extractor or heat the attachment point. Often the starter mounting bolts have special washers that should not be lost during dismantling.
βοΈ Instructions for removing the starter
## Removing the unit and checking the condition
After unscrewing all the fasteners, the starter must be carefully removed from its seat. Engine K4M has a tight space so the starter may have difficulty moving. Remove it slowly, turning it in different directions, so as not to damage the surrounding hoses and wiring. If the starter does not move, check for hidden bolts or interfering parts.
After removal, carefully inspect the assembly. Pay attention to the wear of the bendix, the condition of the brushes and commutator. Often the cause of the malfunction is not the starter itself, but a worn flywheel crown. If chips or worn edges are visible on the flywheel teeth, replacing the starter without repairing the flywheel will be pointless.
What to do if the starter is stuck?
If the starter is stuck in its seat, do not try to pull it out by force. Try lightly tapping the body with a hammer through a piece of wood to knock off any rust. Sometimes it helps to slightly crank the engine crankshaft to shift the position of the Bendix gear relative to the flywheel ring.
## Features of installing a new or rebuilt starter
Installing a new or rebuilt starter is done in the reverse order. Before installation, make sure that all contact surfaces are clean and free of oxides. Apply a thin layer of graphite grease to the threads of the mounting bolts. This will prevent them from sticking in the future and will simplify dismantling the next time they are replaced.
Pay special attention to tightening the bolts. They must be tightened with a certain force so that the starter does not vibrate during operation. Insufficient tightening can lead to misalignment of the assembly and rapid wear of the bushings.
- β Use a torque wrench to control the tightening torque
- β Check that all electrical connectors are securely connected
- β Make sure the starter does not touch other engine parts
## Post-installation diagnostics and operation check
After installing the starter and connecting all the wires, you need to check the operation of the system. First, turn the ignition on and make sure that all indicators on the instrument panel are illuminated normally. Then try starting the engine. The starter should operate smoothly, without any extraneous sounds or jamming. If you hear a grinding noise, stop the engine immediately and check the position of the starter in relation to the flywheel.
It is important to check the operation of the generator and battery charging after installation. Sometimes starting problems are not related to the starter, but to a dead battery or faulty alternator.
- β‘ Check the voltage at the battery terminals with the engine running
- β‘ Make sure that there is no overheating of the wires when the starter is running
- β‘ Do several startup cycles to check stability
Before installing a new starter, it is recommended to lubricate the Bendix bushings and gear with a special graphite lubricant, and not lithol, since lithol may leak out and not provide adequate protection.
