Here's a funny one - anyone come across this.

1992 Range rover Classic.
4.6 litre engine fitted.
Standard belt layout at front of engine..

I keep going through alternator belts.

On close inspection, the alternator pulley seems to be not quite square.
But I can't work out why - the mounting brackets are really sturdy.

Anyone else come across this?

Also - the current 70A alternator - isn't up to the job, so I'm thinking of fitting a 130 amp unit from a VW (or similar) - anyone done this?

I dunno - 250 yards from the MOT station and it threw another darn alternator belt. This belt lasted 15 miles. This is getting tiresome and expensive! Failed the MOT too...

Anyone had this recurring alternator belt issue.

I've had a good look, and the pulleys don't quite line up - but can't work out for the life of me why - nothing's broke or bent.

Ah well - take it all apart again!!!

Mike...

hi when you say not quite square are you talking about belt alignment or the pulley at a slight angle most alternators have one solid spacer some have several is this the original alternator and what make lucas motorola and what type 16ACR etc in other words more ifo and pos picture:welcome2:

it's not a mismatched alternator problem.
The centre of the V-Pulleys all line up in the front-to-rear dimension.
The pulley seems to be not "Upright"

On closer inspection, the bottom alternator bracket seems to be out of alignment, or as my brickie mate would say "on the gimp"...
The bracket is build like the proverbial brick outhouse.
And certainly hasn't been mishandled.
So - is the front of the cylinder head out - it is a later head....

What has changed is the engine.
I fitted a recon unit (upgrading to a 4.6) some time ago - this is when the trouble started.

The bottom mounting of the alternator seems to be not perpendicular to the front of the engine.

I'll have to take it off, and have a closer look - but it's fiddly as hell...

Has anyone else seen this?

As I am in there, I might just fit a bigger alternator - as the current 70A unit isn't coping.
