W108 alternator....is there an alternative?
 

Can anyone advise me if the alternator of any later model would fit into the 250 engined w108?
I snapped part of the casing trying to fit the fan belt.
Opened up a real can of worms on this one.

Most guys go with the later 55A one...and one with internal Reg is preferred, but that takes a new connector.

I would move your post over to the Vintage section..

Thanx Arthur.

fitting a new connector is no hassle.
Do you know if the mounting point/bracket would match?

If you go over to the 113 site and use the search feature, there are a bunch of threads on the change.

All done. the site info was magic!
put on the 55a version and had the auto elec. guy make me a new loom to suit.

Thanx for pointing me in the right direction Arthur!

Very good..

Another good one..., if you ever have Starter problems, here is another easy upgrade for your 250/108. Your starter is only .9HP, but the later ones were 1.4HP..so, they crank much faster and they also have a 3rd terminal on the solinoid that uses Ballast resistor by-pass circuit of the later models. So, you simply add that extra wire and bring it to the coil side of the ballast and you will then have full battery V for Crank. This get a much faster start b/c you then have the more powerful starter spinning the engine over AND a hotter spark at crank RPM... [ the problem with no ballast by-pass is the battery V drop caused by the high starter draw taxed the ignition circuit and the ign coils output..the bypass eliminates the problem , and Benz finally added that to the next model... [ way after USA cars did] ..yours may even have the new style starter b/c that is all they sell now.. if your car ever had a starter change , you got the newer HP version which comes with the solinoid with that extra by-pass terminal ...you can tell b/c the old has the HP stamped on the casing- [ .8 or .9 HP]. Many guys change the starter for a failure w/o knowing that with their new one, they now have all the electrics needed to install a ballast by-pass by simply running a wire over to the ballast...big difference and that mod cost pennies and 10 min. to do..............
..... no comparison to the old and a short $$$ modification. They then start like a new car does...My 113 doesn't even turn over a half turn and fires right up ..
[ 'couse everthing is spot on, too ]

I'll file this!
 

Alls well at the moment. Although somehow I think I'll file this memo for future reference. (Something tells me I should.) It'll make it easier to find if need be.
Thanx Arthur
