Oooooh thanks Chaps!

I am not familiar with the different variations in rubber mounts; I suppose that they might be to fit different alternators. Different alternators were fitted were fitted over time and to different models of E24 depending on regional variation and equipment level. If you have a lathe, you are guara...

Is that with the original M635 BBS split rims? After some issues with the wheels, BMW in the EU these replaced them with 1-piece wheels that look like this: http://www.bmwmregistry.com/faq/E24_M6_cross-spoke_alloy.jpg These are what I have 6 of, included with the car. I also have 10 TRX tyres includ...

Hepu are German too....
:)

Thanks Again Brucey.

I think I will order the more expensive pump as they are not expensive (esp. compared to original BMW items) and I know Magnetti Marelli components are well made.

As ever Brucey, good advice. Whilst the pump is a PITA to change, I currently have the cooling system drained and most of the water pipes off so I guess now would be a good time for preventative maintenance. Any recommendations from you on the best after-market pumps to go for? I cab get the Graf Ra...

If you’ve got the alternator off, why not change the two mounting bearings? They will eventually wear and cause the alternator/pulley to move out of line. Ah haa! So that's why... I was looking at identify the belts I need and noticed the alternator pulley was out of line and was planning on invest...

My alternator bearing(s) had been complaining for years. Determined by a liberal spritz of oil to the location while running. I pulled the alternator for bearing replacement when the water pump went last year, original pump and 82k miles. I had no issue with oil cooler lines in the way. Maybe I bet...

That's a good info, thanks Brucey. I will have a listen to the bearings with my stethoscope but when the engine was running there was no noticeable sound. Also, fitting a regulator will give me a set of brushes into the mix. Can this be done with the alternator in situ? I have removed and cleaned al...

Evening all, Currently the car has good but unknown age water pump and alternator. Whilst I have the plenum removed to fit new BMW hoses and clamps it is easy to get to both. Well, I say easy but it seems the only way to remove the alternator is to first remove the oil cooler feed pipes. I can loose...

Exactly! Here they are. Very close to the original look of the M635 BBS metric wheels (albeit a little more dished) but with 'normal' tyre fitment. They are BBS split rims, RC009 8x17 ET20 (72.5mm CB) fronts and RC010 9x17 ET19 (72.5mm CB) rears. They come with premium rubber (235/45x17 and 265/40x1...

Doh!
Glad you found that my what a schoolboy error!
:)

I'm running 245/40-17 tires on BBS RS198 wheels (17 x 8.5 x 13ET) all around, without issues. That said, I have come to think that 40-series tires may be just a bit too low a profile for these cars, mainly because of the extra stress they place on suspension components. I think next time I buy tire...

Thanks Jose,

Useful info. However, my M635 TRX tyres are 240 wide so in theory, with the right offset 245/40 fronts on an 8.5 rim should fit?

Thanks Chaps, I will remove the diff for a better look but it does only seem to have affected a couple of the larger webs and it appears they may be for cooling rather than strength. Couple of questions please: Any hints/tricks to removing the diff or is it a straightforward job? From the above; I c...

Hi All, Looking for a RHD EU E24 M635CSI diff casing or complete diff please, I think... The car has been in a barn for two decades and the rear diff housing (not to mention exhaust) is a bit rough. Some of the external case webs are really flakey and rusty. If only this had been an old Brittish car...

Not sure if THIS will help, considering your main relay comments but it will at least help identify if the Motronic ECU is getting power and the correct inputs...

Some interesting information HERE

Thanks and agreed. It was one of my concerns, larger rims = lower profile tyres to retain rolling radius, gearing and speedo accuracy. This introduces the risk of tram-lining and whilst this can potentially be dialled out by adjusting toe-in and castor angles it is a challenge to get right without a...

Hi all, I have a good set of original wheels that only need a basic refurb but they need new tyres all round. The cost of TRX rubber is eye-watering and I reckon for the refurb and a new set of tyre I am looking at a bill of £2,200! So, I have been looking around for alternatives. Something that is ...

Now that brings back fond memories of caravan holidays with my folks..... :)

smracer, Have you resolved your starting issues? If not, I found THIS INFO very useful. When I 'found' my car it had not been run for some time and we couldn't get it started. The Motronic article above provides a methodical, step-by-step test sequence and helped quickly identify a faulty sensor. On...

if you are not using the amplifier in the HU then this makes things easier but IMHO really. If your car has AC then fitting a full-depth ISO HU is problematic in an E24; there just isn't much space at the back, it is a really tight squeeze against an AC duct. I have known owners give up on trying t...

I think for a head unit, something like a vintage Nakamichi would be pretty cool. https://www.ebay.com/itm/Nakamichi-TD-500-Mobile-Tuner-Cassette-Deck-Factory-Refurbished-fully-tested/173020748841?hash=item2848d71c29:g:IQgAAOSwl9RaKZSO Cheers, Ray Ohhh, now that is nice. Were Nakamichi supplied wit...

Thanks Brucey, Excellent info around the challenges of getting decent HiFi into an E24! When I lived in Australia, I worked at setting up and managing a custom-fit ICE shop, designing and installing ridiculous kit for clients with more Au$ than brain cells. However, if I were still in the industry a...
