    Default 505: another dead alternator, info or parts

    paris rhone is terminal, have a spare valeo that needs brushes and bearings and im looking for the type number on the brushes box(?) the little plastic box that screws to the back of the alternator which contains the brushes. the valeo has a motorola box on it at the moment but the type number is unreadable,also has ntn bearings which shouldnt be too hard to get but an alternate bearing brand and number would be useful.
    oh well at least i have an excuse to check out the state of the dizzy and tighten up the air con belt while im in there.
    this is a 2.2 by the way

    cheers

    Default 505 Alternator

    Hi Chris

    Easiest way is just take the bearings to a bearing place and buy what the have in stock and take the brushes to an auto electrical place and use their catalogues and the brushes you have for a sample.
    Hope this helps

    I went to an auto elec once, who didn't have the correct brushes. He did have a larger pair though, and I reduced them in size with sandpaper.....after all, they're only graphite. They worked well till I sold the car 10 years later.
    You'll need a baby blowtorch or a really big soldering iron to solder em in though. My 50 watt soldering iron wasn't enough.

    Yes Beano I have done this myself numerous times but best to get the right length (cause the end that makes contact with the slip rings has a radius but if not you can get the right radius by wrapping glasspaper around the slip rings and make your own radius) and make sure the copper tail comes out of the brush in the right place, sanding the flat surfaces is easy with glasspaper on a flat surface such as a piece of flat glass

    Thanks for the tips ! I hadn't thought the radius mattered, and didn't do it last time. But I'll probably have to do it all again on another alternator soon....

    just finished grafting in a 70A bosch alternator out of an xf fakoon. required a 5mm trim
    off the rear top mount and a 10mm spacer between the front top mount and the engine
    bracket. battery light goes out while cranking,13.97v across the battery terminals,looks like
    it belongs in there,all good.

    cheers for tips and info
