Replacement alternator

[andrewwynn]

On the m54 it is not hard once you know to knock the captive sleeve loose it falls right on.

The starter? Different story!

I nearly followed Andrew's lead in replacing the slip rings on my M54 Valeo. That was a cool post. In the end, I decided the fresh brushes of the new VR were hopefully adequate to buy plenty of miles.

AM.

The second refurbish I did only swap brushes not slip rings. I did however swap positive and negative to switch which slip ring gets the most wear.

We had two 2001 e53 at the time and mine was about 16,000 miles ahead when purchased so a few things I got to practice on mine first. Including alternator refurbish and disa valve rebuild. Also siphon jet and door handles and door locks.

I replaced mine when I did the Alternator Bracket Gasket and went with new from FCP (return policy!), I didn't wanna take any chances and never wanted to do that job again. Definitely agree with buying new.

Welp, add me to the list....


196k miles, 2021 Diesel


Was 150 miles from home, headed to a dinner meeting. Pouring rain...red battery and 'charging malfunction' on the screen..... Checked, no broken belts... Drove to the hotel, parked. Ubered to dinner and back.d. The next morning, fired it up and bolted home. Made it about 60 miles (!!!) Tow was 95 miles...love that AAA



Battery red warning was on the whole time, but once the voltage dropped I started geting 4x4 warning, ABS, Stability control..then transission warnings... As I slowed tranny downshifting to lowest gear. Once I pulled onto the shoulder, it switched to Park and that was that- would not move out of park.



Ordered a new Valeo locally, $429, will arrive 10AM Tuesday. Amazon was $381, arrive Wednesday, prolly 7PM out here. (Assuming amazon logistics doesnt poop the bed.) $40 worth the extra day and a half



Valeo 439606.


Took quite a bit to find someone that could get it, TONS of no-name rebuilts.

I usually get most parts from FCP but I prefer to get alternator from O'Reilly's because also lifetime warranty and can find them all over the country.

I haven't had to replace alternator on e70 yet but my current one is suspect as I'm getting a pulse on my serpentine belt that is likely either out of round crank pulley or a bad winding or diode on the alternator.

Might be an excuse to finally get the iPhone based oscilloscope I've been wanting for a decade or two.. you

Did the tow driver know how to put into neutral to pull into the truck or just drag it?

Pricing on a new valeo was all over the place. FCP wanted 542 and wanted $68 to get it here Thursday.


Welp, I was there so *I* knew how to get it into neutral. Actually it was far easier- I had him jump it with a compact jumper pack.... I started it up and drove it onto the flatbed!


Same thing getting off- drove it off, down the driveway and into my garage. Gave him his powerpack back.


My tranny does NOT have the release under the cup, BTW

I think 2011 and newer need to get under the truck and turn in the 5mm hex screw. It's a little scary when truck on a hill!

Just to close the loop.


Idiots at the parts store 'forgot' to order it. Took an extra day, so they matched Amazon 'for my troubles'..$381


Install was pretty easy, bit dirty. Remove the cross brace, remove the fan and fan cowl... I removed the charge pipe, next time I might try to leave the bottom attached. PITA to get the clip back in. Oh, there is a clip on the connector for a sensor attached to the charge pipe- pull the little white tab back AND squeeze it gently with a pliers. (Found a post from Zeta Tre on this.)


Try not to break all those plastic bits!

[andrewwynn]

Usually I'm the idiot that forgets to order. About once a year I go to check on my tracking only to discover the crap is still on the Shopping cart!
