1974 911 Carrera blower motor replacement (part 0130007002)


Recommended Posts

I have stripped down the ventilation blower assembly and identified that the electric motor (Bosch # 0130007002) is dead. Ive reached the stage where I am down to the elecric motor itself attached to the white fan (aka "squirrel cage" as some refer to it). Ive removed the round metal sleeve that is on the outside of the plastic fan at the end of the motor shaft and applied liberal amounts of WD40 to try and help to seperate the electric motor shaft from the white plastic fan. Ive tapped the end of the motor shaft with a hammer but no signs of movement so far.

Can anyone help me with advice on how to now seperate these 2 components (without damage) so that I can fit a new motor?

"Just done this myself. Its quick and easy. I wd40'd the join between the motor shaft and plastic fan then put the assembly on a workmate opened just enough to let the motor through as I drifted it down and out with a small hammer and punch. The plastic held up without a problem. I pressed the new motor shaft into the fan after cleaning lubricant off (I used my workmate and an appropriate sized socket to press as I don't have a large enough vice).

**Measure the amount of shaft poking through so you can get the replacement in the same location as the clearances in the housing are quite tight**"

Edit: I'll also add - make sure you secure the drain tube on the housing before you finish the job.

Many thanks, I thought it was a matter of drifting out the old motor shaft with a punch, but wanted to check first. I have a workmate so I will do as you successfully did.

Thanks for the tip about measuring how much of the motor shaft is visible before doing this.

Im assuming that all Bosch 0130007002 electric motors are identical? - where did you buy your new electric motor?

I haven't done it myself - I just extraced that section from the ImpactBumper.com post. From what I can make out, you have to be brave! I have taken the motor out to lubricate the bearings, but I didn't have to take the fan off.

If the motor has the same Bosch part number it will be identical.
