How to Replace a Car's Starter Motor---Part 5



Remove the battery ground. Now you can go below and remove the wires to the Denso starter. There will be a fat wire from the battery or, if your car uses one, an external solenoid. There will also be one smaller wire, either a ring lug on a stud or a spade lug, from the ignition key. Older vehicles with points-and-distributor ignition may have a third wire to the coil, bypassing the ballast resistor. Don't get them confused.

Now get a socket and ratchet and probably an extension, and remove the bolts holding the starter to the block. You may also need to remove a heat shield, brace or sheet-metal cover to get everything loose. Don't drop the starter onto your head as the last bolt comes out; it's as heavy as a bowling ball.

Don't get out from under the car just yet. Mark one tooth on the ring gear with some spray paint or even chalk, and inspect every single one of the 140 to 160 teeth by turning the engine over with a big screwdriver for one full revolution. Seriously damaged teeth will require replacement of the flex plate or flywheel, which commences with removing the transmission from the vehicle. Fear of the necessity of this should motivate you to fix a balky-but-still-barely-working starter before it damages the teeth. Labor to remove the transmission and replace the flex plate or flywheel will be 6 to 8 hours, more if you have four-wheel drive. Add in the cost of parts and a ring gear replacement could easily reach a thousand dollars or more.

Take your old starter motor to the auto parts store and exchange it. Don't be surprised if the new starter bears only a faint resemblance to the older one. The industry has been transitioning to smaller, lighter gear-reduction starters that use a higher-speed motor coupled to a planetary gearset to spin your engine faster while using less current. The new starter will have grease already in places where it's needed, so no further lubrication is necessary or desirable.

Replacement of the new starter is straightforward, at least if your vehicle doesn't require shimming the new starter. Snug up the mounting bolts, reinstall any braces, covers or heat shields, and hook up the wiring. All you need to do now is reconnect the battery ground, take the vehicle off the stands and start 'er up.

Starter Motor - How they Work (Parts 3) - Solenoids

To achieve this a solenoid is mounted above the starter. Some purists call this bit an actuator, but no one in the motor trade does!

When the starter is switched the solenoid pulls a plunger into itself. The plunger is connected to an engaging lever that in turn is connected to the starter gear (known in the trade as ‘the drive’). So switching the starter pulls a plunger in which pushes the drive out into the ring gear.

At the top of the solenoid are a set of 3 contacts. One comes from the battery, one goes to the starter motor itself and between them is a moving contact. The plunger (which I talked about in the previous paragraph) comes back and pushes the moving contact onto the others, thereby connecting the battery to the starter motor.

So the motor now turns, however as the drive is now engaged in the ring gear before the motor spins, it doesn’t wear out the gears.

On pre-engaged starters the drive has an internal one-way clutch. This slips in one direction and locks up in the other. This is again designed to prevent the starter running with the engine as it helps to stop over-speeding, because when the ring gear is going faster the drive it slips.

So as we all know how important the solenoid is, our factory started to manufacture solenoids on our own so to control the quality as well as the cost. And apply it to MITSUBISHI starterDELCO REMY starterDENSO starter, ect.

Success on Automechanika Shanghai, 2016


The four-day exhibition of Automechanika Shanghai ended successfully on December 3rd, 2016. In the past few days we had an in-depth discussion on product quality, manufacturing process and new product development with our customers from all around the world.

Our replacement of Mitsubishi starter, Delco starter, Denso starter and other products have been recognized by customers. We also hope to promote our products into more markets through this opportunity.

More importantly, we look forward to showing more professional, higher level and more cost-effective products in next fair. Hopefully we will encounter at our booth next year.
