I just made a fascinating discovery:

This component was "functioning" and I only happened upon it by chance.

 

OOPS.

Well found though.

Would have reeked absolute havoc real soon.

 

Does anybody here in the states happen to have one of these laying around that they would like to sell me?

 

I have one I don't need anymore as I ditched my aircon... Though I'm in Europe...

 

This is the tensioner or jockey pulley for the fan belt. Were the same ones also used to drive the aircon? Obviously the cars here have the smog pump as the tensioner for that.

 

found this, its used and to me a bit pricey,

Jaguar USED IDLER PULLEY AND ARM ASSEMBLY - EAC8097-USED

on ebay
Jaguar XJS 1985 Belt Tensioner with Pulley | eBay

 

No they were not used for air con belt. Mechanical fan only.

 

$51.75 (on sale normally 70 )

follow their instructions... that piece will press out and press in the new one: install new pulley

Google Paul's jaguar in Florida...
they even had an new old stock undertray BEC16739 that terry's listed but was sold out...


Paul has always had what I needed...

 

Thanks, that's awesome. I would prefer a new bearing. 51.75 sounds fair to me.

 

Wowee, trouble almost there !!!


1. Can not see what the hole in the pulley
looks like?? OK, or just as bad ?


2. Junk or fixable. I lean toward the latter. Cut that old
shaft off. Drill out the stub in the arm. Fit an
8 grade bolt as a shaft. Fit a brass bush to the pulley
to fit the new shaft. Include a Zerk for lube. Better than
ever.


3. Is the Jagbits or Ebay assembly any better?
I'd trust Jagbits just a tad more.

The bearing was long gone. The pulley was riding on the shaft. Luckily, the tension of the belt held the pulley in place. I ordered an new pulley and bearing and shaft to repair the arm. I have been wondering what the odd squeal was during startup.

 

hahaha that is funny...
and people say that Jaguars are not reliable....
I think that is a go while in Fail mode!
try that on a NEW Car....


not going to happen
