BMW E90 DIY Aluminum Power Steering Pump Pulley

When the left side engine mount on the E90 goes bad and you hit a bump, the engine will bounce and that could cause the plastic power steering pump pulley to contact the frame on some older cars (2007-2008). It's a good idea to upgrade that pulley to an aluminum one to try to prevent that damage from turning into a shredded belt.
The part number is URO-012392. You should be able to get this from most auto parts stores.
Of course the real solution is to replace the engine mounts but that's going to be difficult for some people who don't own an engine support bar or are uncomfortable doing the sort of job where you have to drop the subframe.
Other causes of belt shredding or throwing include:
1. Oil Filter Housing Gasket leaking oil onto the belt causing it to weaken
2. Worn out belt tensioner pulley
3. Missing power steering pump bracket bolts

You lost a lot of weight man! 😳 good job 👏🏽

[@mcnugger8305]

Holly shit man ma boy 50 lost so much weight ! So happy for him:)

[@TheExtraleague]

Literally this is what ownership of bmw makes from you. I have been watchim this guy since begining (now i skipped like year or two) and now i seen a skinny nervous guy.. and im scared.. i remember happy guy with filled cheeks which was heated to his passion.

[@ryanbyers0434]

To align the pulley, get a long bolt the same thread pitch as the pulley bolts from the hardware store, cut the head off, and thread it into the pump. You now have an alignment pin. Get the other 2 bolts in, then pull you stud out

[@50sKid]

good tip

[@Mtown_moop]

Always thorough with the explanations and camera angles ... well done 👍🏾

[@paulmason2629]

Forget the car, 50s kid your looking great, lost a power of weight since i used to follow on the E46 videos. Hope your doing well, another great video 👌🏻

[@tunerworld]

I watched this video already knowing how to do this just because. Brings back memories back into my 335 days. I don’t miss those haha

[@ahahaha2716]

I used an Allen key to line the holes up. Informative video thanks 👍

[@thetoughcookie3665]

I don't have this car, but your videos are nice to watch. I though admit that I miss to see E53 videos :)

Sweating over BMW’s, weight loss!!!

And hair :)

[@burntnougat5341]

I've replaced both water pump and power steering pulleys with aluminum on my E46 and E38. Good insurance on any old BMW

[@lp2565]

Great video, Jason! Thanks for sharing.

[@AlecKristi]

I like replacing plastic parts with metal... I have done my oil filter cap, time to do the pulley ))).

[@Cloverleaf7642]

Brilliant demonstration, thanks ‘kid.

[@bobirvin7991]

That was good. Thanks. Do you have a video that goes one step further & replaces the steering pump. I have an e90 (pump) that is groaning & squealing very bad. (all the other spinning parts are newish: AC compressor, Alternator & all the pulleys)

[@jonathanowen6147]

Wonderful video. So helpful. Thanks !

Hey Sir! Looking good..!

Hey 50s kid i love ur videos..I have a fast question on my 2008 328i sedan (AUTOMATIC), the oil cooler lines r in the way and i cant get the 22mm BANJO BOLT off the bottom of the power steering pump..I tried tons of tools and nothing works its on too tight and im tring to change the power steering high pressure steering hoses..PLEASE help becaue i have been trying for hrs to remove this bolt..I have all kinds of swivels , short wrench-stubby 22mm and all others tool..NONE will work i cant get a socket on the bolt good as it facing down and falls off and the hoses are in the way..hope u can help..

[@deivyleon409]

My belt already shredded off because of this but I had a plate guard for the crank pulley I bought this same pulley so I’m good . But it’s going to be a pain in the butt to reinstall everything because the previous owner stripped my tensioner pulley adjusting hole .

[@brycebabe8151]

Bro ur looking gooooood!

[@oldjarhead1125]

Great video Jason. Thanks for posting. Not to be a pain in the side, but if you also add the Crankshaft Seal Guard, you eliminate ALL possibilities of ingesting the serpentine belt. $80 of insurance.

The problem with BMW's is its profuse usage of plastic parts, that's the root of the problem.

[@oldjarhead1125]

LOL! your bimmer would cost 2x-3x more, weigh 2x more & get less MPG if they stopped using plastics. ALL car & Truck mfg have moved to plastic for the last 30 years. All driven by the EPA

[@davidvenegasramirez6001]

@@oldjarhead1125 yes true but there better engineering solutions out there. Not making critical components out of plastic is a start. Several manufacturers making turbos out of thermoplastics?! Whose dumbass idea was this? Well it’s been happening 🤦🏽 but most of the fuel savings are driven by innovations in aerodynamics because cars weigh 2-3 times heavier than they did 40 years ago. Plus modern vehicles get demolished in wrecks in comparison to their steel bodied grandparents

[@PlymitBoy]

@@davidvenegasramirez6001 Your last statement is not true at all. Have you ever seen the famous Chevy Malibu vs Belair comparison? The Belair literally gets DEMOLISHED. So not exactly sure where you've heard older cars demolish modern ones...

BMW (and all makers) are forced to do it to meet the increasingly unrealistic mileage requirements.

what r the pulley bolts? mine are too long and destroyed the outside of the pump when they spun theyre prob the wrong ones

All E90s. The engine block is the same. Pump in the same place.

[@carlosbonilla1637]

Only pre LCI? Since you said 2007-2008

[@50sKid]

I believe there was an updated subframe part number around mid 2008, which would have showed up in the 2009-2010 pre LCI models. I’m just repeating what I’ve read on the forums. I have not personally confirmed this in the junkyards yet. As I gain more real world experience I will be able to share it in later videos.

[@henryt9254]

The brilliant BMW engineers put a plastic pulley that is a time bomb as a result of their over-engineering BS. Seems to me they couldn't care less of the problem that causes BMW owners down the road. Wonder why people are all ditching their BMWs, take the loss and buy some other cars.
