V12 Vantage Auxiliary belt pulley replacement.

[PatCub]

Just replaced auxiliary drive belt idler pulley, turns out it cross references to a Land Rover Discovery 3 V6 4.0L LR000737 and lots of Chrysler models.
The pulley is a slightly different shape but still works. Do not be tempted to press out the old bearing and fit a new one as the old bearing is welded in.


Old on Left new on right.

I could not get any of my tools to fit into the tight space between the tensioner and chassis, so I bought a universal belt tensioner tool https://www.ebay.co.uk/itm/365824229045 and bent it to fit.

Very good sir but I think your V12 engine could do with a wash..yes im sad but also serious

The pleasure to work on a V12, very tight space. That's why I chose a V8, so much easier to do anything.
