Installing new alternator...

[crc_73]

Trying to install a new alternator, the old one gave up.

Got a new one, but the mounting points are a little wider. I presume the threaded inserts on the regulator side will slide over to meet the mount as the bolt is being tightened, but the inserts seem very stiff. Do they need to be oiled, or will they begin to move OK when the tension is high enough?

Also, the new alternator doesn't have the little 8mm post for clipping on the heavy cable. Any easy way of getting it off the old alternator and transferring?

If it's tight to fit into the bracket then you'll need to push the brass bushing back to create some space.

I'm assuming you're trying to fit a used unit if the cable post is missing.
Has it been snapped off...its only a cable tidy clamp anyway, so not going to affect the alternator function as such.

The gap is too wide at the moment. But if the insert is brass, I guess it should move as it's being tightened. I just didn't know if I should adjust it when its still off, or in-situ with the tightening of the bolts.

The unit is brand new, and the hole is clear. I'll have a look through the packaging for it.

Thanks for your reply.

Oh sorry in that case it should move across into place once tightened up.

Yes, they moved across alright when the force was great enough. I looked at several videos and guides and none of them referred to this. It's not a big deal in the end, but when you've never done it before and you come up against it, some doubts do creep in.

Couldn't find a post in the box, so will see if I can get something else to do the job. But the way the cable hangs, it looks OK as it is.

One thing I noticed different is that the plastic regulator unit is rotated further clockwise so that the D-connector is almost touching the heat shroud at the air intake. Not touching, but much closer than the old one. I hope it won't melt.

Anyway, got it all back together, and all seemed good on the drive to work. No complaints from the computer and good voltage 14.5v on the battery when engine running. Thanks for your input.

Edit: I also have to say that the poly-v belt was much much easier to put back on than take off. I don't know if it was because I had a better idea of what I was doing at that stage, or if that's the nature of it, but it felt too easy and left me quadruple-checking it, but it does look right. I think if it wasn't right, it would be very obvious.
