I'm new to this forum, though I have been active in other Jaguar forums since 2001.
I'm the third owner (since May 2001) of the following 1975 XJ 4.2 L Series 2 with a 3-speed Borg-Warner automatic transmission:
My fan-drive belt recently slid off its pulleys, shredding itself in the process. It's the type that drives the fan as well as the water pump and the PAS pump (see below, circled in orange):
The tensioner spring is fine, all the pulleys run ok, with no wobbling and no sticky spots; there are as well no leaks in either pump. This is what the pump + tensioner assembly looks like when taken off the engine (photo by Eric Feron of jag-lovers.com); mine is still in the car:
I cannot pull the new belt over the four pulleys (crankshaft, water and PAS pumps, and tensioner idler) even with the tensioner pushed all the way up to its stop (the point where it'd provide the least possible amount of belt tension). There is a nut I've slackened (circled in red below; page 1I 13L from the official Jaguar Parts Catalogue–RTC9883CA, of Jan. 1987) that fits through a slit (the one the small red arrow points to) in the mounting bracket (pointed to by the large blue arrow):
Once that bolt is loosened, I should be able to swing the entire pump + tensioner assembly towards the fan (ie, towards the right of the picture in the drawing above). The mounting bracket (part number C.32878 in the drawing) to which the pump + tensioner assembly is attached pivots about the threaded rod shown above as part number C.31269.
I've tried using a long piece of timber as a lever (the fulcrum end pressing against the body of the car) to push against the pump, but to no avail. A hammer (used with caution and only hitting directly on a wooden block sitting on bubble wrap on the side of the pump) wasn't of much use, either.
What am I missing here? It's as though the mounting bracket (part no. C.32878) were welded to the attachment (C.31302) that is fixed to the engine block, both forming one solid piece–when the bracket should in fact easily revolve about the attachment using the aforementioned threaded rod (C.31269) as a hinge bolt.

Hello, Yago,
I wish you success in your repairs.
I'm afraid I can't help you with this as my car was converted to Chevy 350 well before she came to live with me.
Thank you so very much for your warm welcomes and advice–I'll check out the responses to my post in the technical section, thanks to those of you who have redirected my post there.
Thank you so much! It is indeed gorgeous, I must admit–as my own drooling can attest! :-D
It shows 97,814 km (≈ 60,800 mi) on the odometer right now–how many it's really clocked I do not know, though.
However, it went through a major cosmetic restoration in 1998 while under my brother-in-law's ownership and I put it through another major restoration in 2004–this time mechanical: full engine overhaul plus Borg-Warner auto tranny rebuild.
By the type of wear-and-tear revealed with both the engine and gearbox completely stripped, the odometer must have gone aroundat least once (one 'lap' = 100,000 km ≈ 60,000 mi).
Cheers, Y.
