OK,

X300R.

Drove it 2000kms home, sweet ride.

Now a slight "squeak" at times on start up cold.

New belts were fitted prior to the trip home, so first stop is belt adjustment, now they have bedded in a tad.

The Alternator belt is slacker than I would like, so out with the 14mm spanner, and then the brick wall got hit.

How on earth do you get at the alternator adjuster without removing the Supercharger, or maybe the Supercharger belt????

I managed, by feel, to loosed the outer nut, but the inner nut is eluding me at the moment.

Visibility is zero, so any ideas would be nice.

Doug will know, and the 8 hours he mentioned before for the lower radiator hose sounds like this is going to be tons of fun also.

 

Grant,
The supercharger does not need to come off, although you may find access improved if you remove its drive belt.
It is basically an imperial quality PITA. Slacken the alternator pivot bolt from underneath the car. Everything else is approached from the engine bay.
Slacken the pivot at the base of the threaded adjuster rod, and then begin turning the adjuster nut itself. It is basically one flat at a time, and if your belt has a lot of slack, you will find the end of the adjuster rod gets very close to the supercharger body, but manages just to avoid contact. Not Jaguars finest piece of engineering, but the belt does seem to stay tight once it is settled. Nice adjusters like those on the A/C and supercharger belts would have been too much to ask, but I am sure alternator belt adjustment on a normally aspirated car is pretty straightforward, so just a throwback from bolting the supercharger on.
If you have any three year old mechanics in your area, their hands are better sized for the task!

 

Thanks for that.

My 3.2 Poverty pack X300 is a snap as you said.

I will consume some courage after breakfast and do what is needed.

Maybe only 6-8 flats needed, so maybe 4 hours worth.

One belt doing it all would be smarter.

Thanks again.

 

County gave you the info you need; right on the money. Once you get yourself into a comfortable position the one-flat-at-a-time adjustment process isn't so bad. Tee hee.

If the cold-start squeak persist, though, start looking for someone down under who re-bonds harmonic balancers....because I have a funny feeling that's what you'll be facing.

Lower rad hose? This will give you an overview.....

BUGGA.

Nearly easier to take the engine out, and do it ALL outside that bay.

The hose on this car is NEW, as the Supercharger was refreshed 4 months ago, and they did the water pump as well. Barely driven until I got it.

PO did it at a dealer, OOPS.

 

My thoughts exactly. I "white lined" that pulley at the Motel the first stop home. It has not moved in the 1600kms for the rest of the trip, so maybe I am blessed, ha.

Iglio Engineering, around the corner (Aussie corner) from me does them. He has done a few V12 units for me over the years.

The Alternator belt is quite loose, about 1" easy flex, alternator to crank pulley.

 

Ok, good ! An already-replaced lower hose is obviously a check mark in the "plus" column. Who would think that a radiator hose would be such a significant repair on a car?

It's sorta funny to think that, if given two otherwise identical XJR/6s to choose from, the one with the recently replaced hose should absolutely get the nod.


Dear lord, I'd hate to see the invoice.

Grant, did I miss a post, or have you just bought an XJR?
If so, can you post some photos?
Cheers , Al

 

If you tighten up the alternator belt without removing the SC belt make sure that the SC belt is properly aligned before starting the car.

I once adjusted the alternator belt this way and accidentally pushed the SC belt a few mm sideways at the guide pulley, which resulted in a damaged SC belt..

 

Well do.

This is now today's task, the pain killers have kicked in, and arthritis stiffness is reduced a small amount.

 

All done.

Not a task for the side of the road by any stretch.

NO squeal, which was the object of the exercise, and the timing paint line from 1600kms ago is still in line, so damper rubber is holding.
