1997 Wolf 24v Alternator Alternatives.

I have a cracked alternator casing, so does anyone know of an alternative to the original?
TIA

Buy a replacement 24v unit or strip down existing and have the old casing welded up. Alternators usually split at/through the mounting thread holes where they've been over tightened and no washers used.

very expensive new john richards £750 but then its has the manufactured water proof cover and rear fan but at the end of the day it's a modified A1271 50/24volt MANETI MARELLI Alternator rated at 50 amps where the fan has been repositioned on the rear so maybe the parts are interchangeable using £79 https://www.ebay.co.uk/itm/37263882...bfe1cd3a7339b815&pid=101195&rk=4&rkt=12&sd%as a donor

Thanks mystery.
That eBay listing says that it is rated at 100 amps.
Is that not too much for the Wolf's 50 amp system?

Sorry mystery, did you mean just the casing?

the alternator will only output what is demanded or as v8250 suggested strip of the case and get it tig welded

Surely brazing would be better, less heat stress on the frame

Braze would would work but a good tig welder can weld the casing - only potential issue is that alternator casings are not a very dense alloy...so may be a braze would be better.

I'd second replacing the case, or you may be lucky and TIG weld the crack .... To braze it you'll need Oxy Acetylene or a very good propane torch - plenty of guides on the web ... The thing that would make me nervous of welding or brazing it, is that the precise alloy is unknown ....

You might be able to buy the case parts from mid ulster rotating electrics:-

100 amps at 12 V is 1200 watts - 50 A at 24 V is ..... 1200 watts ...

The problem with any heat treatment is that there is zero guarantee that the armature and bearings will still align afterwards.

Anyway, I read someone else's post on the dreaded FB and that lead me to this one, which even has the correct pulley and just needs the rear cap from the original transposing
