Hi All, looking for pictures from the OEM SC layout from the pulley side of the engine if possible. When rerouting my chargecooler hoses recently I noticed that my SC nose bracket only seems to be attached to the car in one place, and it looks like it should be attached to the top of the alternator too… but isn’t.
This may just be normal, but I do know that my charger’ has been off in the past (a new MP62 unit was fitted in 2012) so just want to check it’s been done right.
This is the only pic I can find online, but might be an aftermarket setup?
Here are some endoscope shots of mine:
The “top” bolt is mounted as expected:
But the other end is not attached to the alternator:
Since viewing it with the endoscope I’m now more convinced as the bolt hole in the alternator looks very clean for a 14 year old car, and it looks like possibly a bit of galvanic corrosion on the face of the bracket where the bolt flange used to be…
The only thing I can’t get my head around, is that surely this means the alternator is on the piss, but if that was the case how could the belt be holding tension?!
I’ll get the aux belt off tonight hopefully and see what I can see through the arch liner, but it would be good if I could sanity check this against another car first.
Yup that was my first reference, slight flaw in using these exploded diagrams is when you’re trying to figure out how two distinct areas connect to each other!
I’m leaning heavily on the fact it should be attached, I just can’t get my head around how my belt is still at the right tension - and as far as I know the alternator is also held in with just one bolt currently, meaning it’s vulnerable to swinging around!
I dread to think how much hardware I’ve pinged out of the back of my undertray towards oncoming traffic over the years
I can only assume that the alternator is still fixed in position by its one remaining bolt, and the tensioner has done its job taking up the variation in effective belt length. I’ll get it sorted tonight
Shows a little bit just how much the alternator is out of position! I took the belt off and the alternator is stuck solid in that position, there’s no way that the bolt could have come out and the alternator slumped into that position. Only when I undid the (very tight) bottom bolt for the alternator could I rotate it back up into position to line up with the bolt hole.
Maybe the bolt did come out and the force of the belt and high RPM was enough to pull it down into that position, but either way I’m amazed that the tensioner was able to deal with that and stop the belt jumping off!
In any case, it looks like I need an M8x45mm bolt and a 15mm spacer - so will go for a rummage later.
Belt was a LOT harder to get back on than it has been in the past, so looks like I’ve gained some “tightness” in it with the alternator in it’s correct spot, but man of the match must go to the tensioner I guess for keeping everything in line for however long it’s been like that!
