Some great info, I may do it on a later time. For the meantime, is tehre any place I can get the blind? My E32 has the setup in the rear for a blind but I cant find one

Mabey just go to the Stealership?

[shogun]

try to get a used one from an E34 or E32 including all the wires and the control unit.
And the gear is usually broken, it rattles because the control unit only switches the gear/motor off by increased ampere. That gear is not very solid and is made out of a kind of weak plastic. So by the frequent overload that gear breaks, also on early E38, E31, and Audi 5000 as well as some Mercedes benz models.
Gear and motor are only available as complete set from the dealer.
But shogun has the solution, the one and only in the world, steel toothed rim ;-)

just sent another one to Poland yesterday.

specially produced again to replace the weak original plastic wheel/toothed gear which usually loses the teeth and then the rear sunblind starts to rattle and is often inoperatable. Used in all E32, E34, E31 and even E38 till 1996 for sure, even some till 1998, also some Benz and Audi 5000 models. Shogun special: http://forums.bimmerforums.com/forum....php?t=1397812

marshalperry: 1 toothed wheel for your E32 was just sent out to Las Vegas, NV

if you have that grinding/clicking noise that keeps on for about 5 seconds after the blind has come down? And it runs up and down just fine, but makes this horrible sound after it has come down. Thenmost probably my steel toothed wheel will fix it, typical sound when the teeth are gone/damaged on that original weak toothed wheel in the special area where it needs much power. Here a damaged original one http://evansweb.info/files/_images_a...35231115_5.jpg

The problem is that there is no limit switch for the sunroof motor, the motor stops only with a delay time of some seconds when the ampere goes up, and that damages the soft gear. That is why my one is made of steel. That is the larger one of the 2 inside the gear, the smaller one breaks very seldom, but sometimes too.

That is the one with the hexagon nut, not with the torx, see here the difference. The one with the torx was introduced from around 09/1996 in the E38, but it looks they mixed up the stock there, as the old ones were found also in E38 from 1998 sometimes.
Also used in older Mercedes Benz and Audi 5000.Here both shown, this one I have

Tron5: 1 toothed wheel for your 95 E34 525TDS was sent to Torshavn, Faroe Islandss

Edit: additional upgrade possible:

upon request of E34, E32 and E31 drivers I also can offer from now on as optional extra the bush for the guide pin for the smaller gear part in addition to the large toothed wheel in steel version. Here some pics of the set from various angles, both parts are special made

Reason:
Another problem for damages of the gear is the bush for the guide pin for the smaller gear part, when that bush get's damaged, the gear parts (small and large)touch each other too much.
Since more than 1 year some of my friends were testing this bush with good success together with the steel gear from me.

Repair work is of course at your own risk and ability, if the hole is not drilled very accurate, your repair attempt might not work

Here another good DIY instruction to replace the toothed wheel, from E31, but same procedure for E32, E34 and some Audi and Mercedes Benz models of same built years, they are have the same window motor/gear up to around 1996/8, when the torx version came in the E38, this one has the hex nut, Reparaturstory - Zahnrad Heckrollo wechseln http://www.facebook.com/media/set/?s...7144517&type=1

Received the toothed wheel and the bushing today, thanks Shogun!

@scasey
1 x steel tothed wheel with hex nut plus 1 enforcement bush for your E31 850 was just sent out by EMS to North Vancouver, BC, thanks

hi shogun

can you supply for an e31 850i, my blind just makes a noise when i try to activate. not sure what parts i may need. i tried to pm you too.

thanks

[shogun]

Hello Richard, yes, I have stock of the large toothed with as well as the enforcement bush. But before you order, you have to disassemble the gear and see if the toothed wheel is really damaged and the cause of the problem. Could be the toothed wheel, or overload for the motor due to dirt in the complete sunshade mechanics, or the control module is defective.The control module switches off by increased ampere with a delay time. Here is a German instruction to test the module with pictures http://www.e32-schrauber.de/bmw/s-heckrollo.htm
Typical sign of a damage of the toothed wheel in the gear is rattling = slipping of the damaged toothed wheel inside the gear.

@indiosse: 1 x toothed wheel + enforcement bush shipped to U.K. for E31

[youngbimmer]

I may possibly need one...option spec on the 735iL I bought shows option 415...I'm assuming this is the electric rear blind, and it probably isn't working

[shogun]

no, you do not need one, as yours is a manual operated sunshade
415 = Sunshade for Package Shelf, manual
416 = sunshade for package shelf, electric

[shogun]

Just for info: got another batch toothed wheels (the one with the hexagon nut, not with the torx as used from late 1996 on in E38) + enforcement bushes made and ready for despatch if needed.

[Wzu25]

Sorry to revive this but i need a repair kit for a blind...how can i contact you Shogun ?

[shogun]

send me a PM, have stock of the steel toothed wheel as well as the enforcement bush repair kit. But that does not fit on your E53 X5 3.0d and E39 525d.
My repair kit only fits in all E32, E34, E31 and even E38 till 1996 for sure, even some till 1998, also some Mercedes Benz and Audi 5000 models of same/similar built years.

Dam you can see my post from 2009 wanting to do this! A few months ago I picked up an electric blind from an E32 at the junkyard! Its sitting in my storage unit awaiting my install. I pulled out the harness and switch. Looks like I have the connector inside the drivers rear seat! I will eventually get to this.
