I have an issue with my starter Motor and would like to change it.
Does anyone know the Bosch or Hella compatible spare part number?
Is it the 1.4 kW version?
10 or 12 Teeth?

Thank you for your help.

Hi - what is the problem with your starter motor?

I found Wood Auto very good for parts when I had issues with mine. Their website is:

woodauto. com

They have a huge stock of motors and parts, plus their knowledge is exceptional!

Sometimes the cog doesn't t engage on the flywheel.

Thank you

I had a similar problem some years ago. Initially I thought it was the battery that was failing, but changing that didn't solve the issue.

Speaking to Woods, it was suggested that it was the pinion and lever. I bought a new assembly from them, fitted it myself and the fault was sorted.

The part number for that is SDV3198.

This is how the cog of the starter looks like:

Check the ring gear on the flywheel as well....

The ring gear on the flywheel seems to be ok, but I will double check it asap.
Note:
All the parts have been changed when we changed the clutch assembly as far as I can remember
The car was only started a few times since then.

Still under construction with an enormous delay caused by the pandemic...

Thank you

The amount and type of wear on the starter pinion, along with the corrosion on its shaft, suggests the lever/pivot assembly that moves the pinion into engagement is very worn or sticking.

The good news is that the assembly can be purchased and replaced.

Alternatively it may be the solenoid isn't pulling down as far as it should. Stripping down the motor should reveal any issues.

This is the replacement flywheel from Elise-Parts that we mounted when we replaced the clutch assembly.

I already ordered a regenerated starter motor, but will probably dismantle the part and have a look asap
and probably repair the oem part from Magneti Marelli.
