I'm considering polishing the outer body of the alternator... I'm just wondering if it would be an easier idea to get an old one that's broken and remove the outer body then after doing the work on it strip mine and place it in the polished body , is it as simple as that or not ?

i have the spare one and interested in doing the same, how much work is involved in taking them apart?

Must be do-able, someone builds them..........but they may have a machine with three hands to do it.

I recently stripped and rebuilt a Xantia starter motor, (three times.......don't ask, ), and it was dead easy.

Get a non-working one and have a go.

Go on then alcazar I'll ask ? and yes it must be do-able I think as well.

Come on then Ricey get the camera and spanners out let's have a look see

I'll see if I can get anything done this week in taking it apart! I did think about giving it into an engineers to strip and polish! lol

Bleddy thing was chock full of diesel from a slight leak on the fuel filter, straight into the brushes end. Stripped to check cleaned up, refitted, it worked for a while, but then went slow again, (the commutator was getting coated in black gunge), did it again, thought I'd cured the fuel leak, but no. Did it again, but it was knackered, so had to be replaced

All in VERY cold temperatures, raining, outside

What a nightmare and it's always the most awkward jobs.

I'm beginning to think thare aren't any other types of jobs on Xantias.
Change foglight bulb: bumper off.
Change washer reservoir/pump: bumper and wing inners off.
Change dash light bulb: airbag off, steering wheel off, half the trim off.
Change o/s headlight bulb: grille off, headlight trim off, sidelight off, headlight off.

The fekkin thing was designed by an idiot.

The problem with polishing an alternator body is getting the field windings out of the casing. When I rebuilt them it was usually a part that stayed in situ, as the ferrite cores would rust solid into the casing (ferrite+alloy = not good)

Still do-able though. Being alloy, it would need something on it to stop it going dull over time (laquer?) Anodising/plating would be best, but you'd need to remove the field windings....


Anyhoo, stripping the other bits on a alternator is pretty straight forward (baring seized steel bolts in alloy threads - get some "rost off ice"). Three main components; Brushbox. Armature and casing, the casing splits in half with the winding staying stuck in the larger half. The rest is washers, bearings and diodes and pulley. Basically just like an electric motor.

Get a broken one or one from a scrappers to practice on; most are very similar in design regardless of manufacturer. Disassembly goes a bit like as follows: Remove pulley first, remove regulator/brushbox+brushes (sometimes behind the rear cover), then split the casing. You may need to de-solder the diode pack to get the armature and windings out. Plus keep tabs of where the washers and post insulators go

Here's a random diagram of one; most are pretty much the same. http://www.cityharness.com/userfiles...or_diagram.jpg

I'm sure the worshop manuals in the archive section have an exploded view

Spot on Ali that's a good help there... I'll see if I can find a broken one for sure first, it may be possible to polish in place we shall see. The polishing mops are not to aggressive so it will be good to see how this can be done.

something like this ?


Takes about 6 hours to strip,clean, polish, paint(stator and pulley), and clear coat it all.

Why not fit a nice alloy pulley too?


Otherwise good job. Post a guide? It's the sort of thing I like doing........I used to take bikes to bits just to clean the bits properly

bump I'm stuck removing the coil part from the lower ally shell...?

In the end I simply polished mine intact, just go at it lightly then I took it to work and used an air gun to blow it through.
