Supra JZA80 How to Replace Starter Motor

First, jack up and fix it on the stand. At the same time, it is easier to work if you remove the front left wheel. It is even better to remove the front bumper if possible. If you have a lift, you don’t have to this.

Remove the Supra starter motor from below.

All you have to do is remove the two bolts that secure the starter motor. However, it is very narrow and difficult to work with. This may be true not only for 2JZ but also for 1JZ. By the way, the bolt diameter is 14mm.

Remove it by making full use of the 14 mm socket and the long extension and universal joint. If you loosen it with a torque wrench first, you can remove it easily. Be careful not to drop the bolts as they are long! It is safer to wear protective equipment.

If it comes off so far, remove it while being careful not to drop it.

This is where the starter motor was. It’s a good idea to check the condition of the flywheel! My one has been a little scraped, and it was a level that I should replace it soon or later. I wonder if I will use a lightweight flywheel next time!

Assemble in the reverse order of removal. Finally, check each part for looseness, start the engine, and then check the reaction speed and abnormal noise. If there is no problem, it’s done!
