hi my alternator packed up at the weekend  it looks very like the 140a one not the bosch 120a. defo not like the one in the guide here.

i cant see a part number but bosch is printed on the black plastic back (regulator?)

am i going to have to get another 140a to fit or will any others fit? 140s seem to be hard to find. anyone know the bosch part number for the 140?

no bearing noise so i guess the regulator is gone, is the reg standard and is it possible to fit a new regulator with removing the alternator?

its a 2001 elite V2.6 full face lift

thanks

You can pick up pattern regulators for those for around £30.

Mine came from here:

Mine's gone too and I've chickened out of rebuilding mine so have bought a reconditioned one from ebay for £70. 

Here's another company I found for alternator parts.

I'll have a 140 amp alternator if you want one

[omega2018]

just took the sump guard off and managed to read the back of the old one - it is a 120a xa. this is as vauxhall say it should be for my car but the alternator looks like the 140a xj not the 120a xa in their catalogue, very odd.  the xa diagram shows the mounting holes 180 degrees apart at opposite ends of the body, mine has holes much closer  120 degree approx

part number i read is  091 0 124 515 049

decision now is
1 buy scrap one £30 and take the chance it will last
2 buy a refurb regulator £20 and hope that was the problem
3 buy a new pattern alternator or remanufactured £50-£60
4 buy a new bosch one £480!

all of the V6 alternators have the same mounting lugs

[Marks DTM Calib]

Yep, mountings on the V6 are all the same.

Regulator repair is dead easy on them, bearing change a little more involved.

[omega2018]

are the connectors the same on all V6 alternators though? 

if i go down the recon myself route, do i need to change the diode as well as the reg and bearings?

thanks

I'd put money on it being just the regulator that's faulty. Bearings you will probably get away with but if you've got an hour or two to spare to strip it down and swap them it might be worth doing. See how they feel when you get the alternator off.

'orrible job! 

[Marks DTM Calib]

Dead easy to get off, 45 mins to change one

With practice bleddy show off

Took me a lot longer than that.

Smartarse!!    See my tale of woe in Car Chat.

The key is being able to feel your way to the nuts at the back of the alternator, 'cos you can't see anything. A background in gynaecology might be an advantage, it has to be said. 

I've certainly done worse jobs.

alternator is out now  wasn't as difficult as I expected.  in fact getting the bag pipes out was the worst bit.  i had already taken the rad bottom cover off but that was not needed i could get a small drive and 11mm socket round the back ok from above.  had to put a crowbar on the alt to move it mind.

the two long bolts were in opposite ways  torx end at back on top bolt and at front on bottom one is that normal?  no spring washers either.

now its out it the bearing seem fine no play i can feel.  im tempted to skip bearing replacement and just replace the reg.  are they any other things to replace eg diodes?

im new how long do i have to keep filling in this verification code for? its annoying.
