What did you do to / for your E53 today??

[andrewwynn]

Great job on diy bearing swap. I have to do that same one on wife's car soon. I re-engineered my bearing press to use 1" bolt up from 3/4 after I stripped three sets of 3/4 " bolt swapping the front right bearing on mine and wife's E53.

The 3/4" bolt is good for about 23,000# force the 1" is designed for 62,000#.

The math worked out to about 25,000# to install and 35,000 to remove the front bearing. Brutal, and destroyed the bolt and nut that came with the kit and the stronger replacement bolt as well.

The rear doesn't seem nearly as big and explains why you likely didn't have a problem just be aware if your kit like mine has 3/4" bolt it will likely not have the power to remove and replace the front bearing.

Very astute to realize good thing and the new noises. It's very bad when some constant noise masks the other telltale sounds of slow destruction.

The one negative of my new positively bad ass tires is that from 15mph down to about 5 they make a 500Hz down to about 100Hz hum that will mask some telltale sounds like scraping brake pad etc. it sounds very much like a worn gear in a transmission but it's subtle and only noticeable on deceleration so hopefully if I ever to get a new wearing part sound that will show itself on acceleration also.

The fact I can accelerate and brake with half the rate of dry pavement on slush makes up for it however. (I was able to achieve nearly 0.5g braking on wet slush)

I'm trying to figure out if I can use my bearing press to replace my rear bushings which are shot. They have a specific tool to do that swap but only that job. I'm not sure if the cups are big enough but I digress.

Awesome on the diy bearing swap sharing your post will definitely encourage others to do the same. Also *others*: this swap can be done without special tools, you can hack together a bearing press with some pipe flanges and large sections of galvanized pipe. For $20 or so vs $100 kit designed to do the job.

Replaced the sliprings on my alternator.

$20 versus $325? Yesplease

I have noticed that only one polarity (pos or neg) takes all the beating. Switching the polarity at say 125,000 miles would likely double the life of the slip rings. I'm thinking I will do that on my wife's rather than wait for it to self destruct and require new brushes and slip rings.

Anybody ever heard of this.

I know in arc lamps the anode takes all of the abuse so I'm betting the top ring is the positive and is bombarded by electrons. Anybody know?

Replaced the air filter and #5 ignition coil, then realized I didn't have the socket extensions required to do the plugs. Oh well, runs like a champ again. I'll do the plugs when its not raining.

New tires on my stock 18" rims, replaced MAF and Door Carrier on front passenger door.

Added these to the back of my 4.8 after coding out voltage monitoring for the plate lights using Carly. They are BRIGHT. This shot was taken during mid day with the X's rear just at the garage door opening.

Mine weren't monitored. Which one did you get? 36mm or 41mm? Looks great

Give us the lead an where one can acquire such nice license plate LEDs???

Replaced slip rings and brushes on my alternator (finally!) and took in for testing (passed) before reinstalling.

At the parts store where I had it tested, they had to look up the same part to know what code to use with the test machine and the refurbished model of my alternator was $250. The kit to do 80% of the refurbishing diy was $19 on eBay. I think the full kit that also replaces the bearings (unneeded in my case) is about $35-40.

Tuesday should finally get time to put back in. Thanks to Metra Amtrak and Lumba2 I've been able to avoid working on BMWЯ in the subarctic temps of southeast wi. It will be great to be a two car family again though.

When I have a chance I'll post the video of my tips for swapping the slip rings. My method to remove the old slip rings is a lot easier than the chip away with screwdriver and crush in a vice method of the muse I copied to fix mine. In the photo you can see the gray epoxy that is covering the new wiring.

36mm. Thanks. I think they add one more touch of modernity to help keep the e53 chassis looking fresh. It's a little thing, but they add up.

I linked them in the original post, but admittedly, not very obviously. Here you go:
