Well finally did the bearing replace on my blender...ah I mean spoiler! Sheesh what a cheapo bearing Porsche used!! Shame on them! Mine was almost completely rusted! (no pics just too ugly to believe).

Anyway the new bearing is stainless double sheilded, abec3 and sealed/lubed for life!

And man is it quite now. I can just barley hear a nice whirring sound as it retracts. Thanks again to Robin(P-Car.com) and Rennlist for all the DIY stuff!

 

It's great to be silent when you pull up at the lights. People used to look at the car making the grinding noise !! Did mine last weekend and the old bearing just fell apart it was so bad.

 

Is there a part number or source for the bearing?

 

I went with BOCA bearings (ordered online) and selected a double shielded, ABEC 3, sealed,greased, stainless one. I have the part number at home if you want I can send it to you. It cost me around $13.00 and is of MUCH better quality and design than the original open face type. It is If I remember 16mm OD 5mm ID and 5mm wide. In Europe you can most likely order one from an SKF dist.

 

I suggest using a 625-2RS (sometimes known as 625DD), which is a sealed bearing. I put "625 2RS bearing" in Google and ordered for £2.00 - about $4.

 

Hi --

Just replaced mine. What a difference. First disassembled and tried to clean/lube bearing, but still made bad noises.

Ordered a couple of sealed, ceramic bearing from boca, got them in 3 days.

Also noticed when tinkering that the contact switch for the down position was not making contact with the adjusting screw (there are up and down swithes, and adjustments for each for fine tuning).
So I added a washer in the main pivot to keep things better aligned when moving, and now the screw hits the lever on the switch.

Quite a bit of engineering going on under that @%#$ spoiler!

Anyway, ditto on the thanks to pcar.com and rennlist for the DIY.

Another fun project!

This sounds an easy and inexpensive DIY .... must do must do ......will get bearings ordered next week...thanks for prompt

 

Actually it was not as easy at it sounds. My gearbox (for the spoiler) case did not want to come apart. Took a lot of patience and a sharp x-acto knife to convince it. Also, I had a heck of a time getting the old rusted bearing off its shaft. Finally had to break it in half to get the darn thing off. Even then it left the center bearing race on the shaft! Also my cable connector was very tough to remove. In the end I was able to get it appart and now it's awesome. I really don't hear it at all unless I try. And be careful with the Nylon Ring I dropped mine in the black hole we call an engine and had to buy a new one from Pelican Parts!!

 

Hi Jeff, where can I find the DIY on pcar.com and Rennlist? I've been looking at http://p-car.com/diy/diy.html but I can't seem to find it

Try the above link - should take you there.

Could you here it while you where in the car? When does it retract?
I bet that's the noise I've been hearing when I come to a stop after driving at highway speeds.... :-))

 

Yep that's it. Goes up at about 55 mph and down when you stop. Sounds like a coffee grinder !!

 

Thanks Monty!

Yeah, that's it! it's like a grinding/rattle....
I'll check it out.
thanks!

 

is there an easy way to stop the thing from operating just to test the theory?
