    Brass TC actuator gear?

    Just out of curiosity here, and I guess also so I know in case I need to replace my gear down the road... anyone have any experience with the brass actuator gears like the one made by Uro? It looks like several BMW vendor sites sell them online (e.g. https://www.ecstuning.com/b-uro-parts/transfer-case-motor-gear-brass/27102413711~uro/), but I can't find any reviews or other information about them.

    I have read a few posts warning people to stay away from the aluminum gears, but can't seem to find anything about brass.

    Thanks!

    Hi cjb762, brass Transfer Case Motor Gear 27 10 2 413 711 is a brand-new item for us, which is why there aren't any reviews yet.
    https://www.uroparts.com/uro/inventory/show/10742

    Edit: jer0177 is going to do this review. We'd be happy to provide a gear to the first person who needs to repair their X3, X5 or X6 transfer case (due to a stripped plastic gear) and wants to post their unbiased review of our brass gear on the forum (including photos and details). If this is a repair you're going to make in the next few weeks, post here that you're going to do the review and send us a PM with your name and shipping address. We look forward to your feedback!

    That is a great offer, and thank you for responding! I almost wish that my actuator gear was dead.

    In the mean time, do you have any information you can share from the development and testing of the gear?

    Can't really share any engineering specifics (which would be boring anyway), but the gear is made to the same dimensions as the original plastic gear and functions the same. We also sell replacement brass gears for Porsche convertible top motors, which allows owners to repair their motor assemblies instead of replacing the entire assembly as a cost of almost $2,000.

    It's now common for automakers to use plastic instead of metal for a lot of parts, in order to reduce weight to meet fuel efficiency regulations. Many of these plastic items only last to the end of the warranty period before wearing out or cracking, if you're lucky. Fortunately it's perfectly legal for the aftermarket to provide these parts made of metal, as they should have been in the first place.

    ^ Received your message LetaG, unfortunately Transfer Case Motor Gear 27 10 2 413 711 only fits BMW X3, X5 and X6 (and some Land Rover and Mercedes), and we don't have one yet for your 328xi. We'll let everyone know if/when we have them available for the E90. Bummer!

    Oh, I wish I had contacted URO first, I paid full price. Haha. I purchased one of these for my E70 X5, but have not installed it yet, mostly because it's more difficult to get to than the E53.

    I just picked up a 2005 X3 3.0, and it has the indications of a stripped gear (brake/abs/4x4 lights on). The problems aren't exactly like what's been described elsewhere (the lights aren't on when I start the vehicle, and come on/go off as I drive, and when they're on, it feels like the TC is locked). I'm going to be pulling the servomotor anyways and replacing the gear - and would love to review it for you guys. I'll send PM.
    Knowledge isn't necessarily knowing the answer, but knowing where to find the answer.

    ^ Sounds great jer0177, your gear for the review should ship tomorrow! Once in awhile the problem with the assembly is both a stripped gear and dead electronics, but the gear is the first thing to try. (Nice old-school ICQ icon, BTW.)

    Great! Looking forward to getting it swapped out!

    Yeah - haven't used ICQ in ages, but the icon's still there.

    Yeah - sorry. Took me until last week to actually get it back on the road. Long story involving trying to find someone to rebuild the ABS tone rings on the rear CV shafts for a 3.0i 6MT.

    The brass gear was a great fit, and even though the plastic one it replaced looked almost new, the brass one solved the problem of the "trifecta", and it's definitely not going to wear out!! If you're having problems, I definitely recommend it!

    Awesome! Thanks for the feedback, and please let us know how it is working down the road...

    Glad the repair was a success Jeremy! Our brass gear is definitely a stout piece.
