This is a revelation as I wouldn’t have thought Welsh would sell a
replacement part for something that was not offered in the US market.
I will give them a call and see what is up.
Sorry. I was referring to the Jockey Pulley bearing. The jockey pulley
tensions the water pump belt. It is not the idler pulley that goes in place
of the air pump. Thought it may use the same bearing.

Actually, I think you’re talking about the jockey pulley that
tensions the fan belt. The water pump belt is tensioned by the power
steering pump.
Actually,
I just checked out their website and they do list the bearing! EAC3042(pg
I05 in RTC9900CA) and I have emailed them for a quote. It does look quite a
bit like the water pump bearing but has a different part number!

The bearing on a water pump has the shaft sticking out both ends,
with the pulley going on the front end and the impeller on the back
end. The bearing in the idler and the bearing holding the fan clutch
are similar bearings except the shaft only sticks out the front end.
If that’s the only difference, you could use the same bearing and
just cut the back end of the shaft off. However, there are LOTS of
other things to check, including OD of bearing, length of bearing,
press fit diameter on shaft, length of shaft, etc.
Besides, using a bearing from a Jaguar water pump would be expensive.
I suggest using a bearing from a Chevy water pump, which use similar
bearings but the entire water pump can be had for less than $30 or
some such.
Well I guess Welsh isn’t the solution. They are more expensive than direct
from the UK from some suppliers I use there.
I will look at finding a good general bearing shop and see what they might
have. I might have my father (a machinist) make up some sort of adapter
which might accommodate another type of bearing.

comments: Could you please quote the price for the bearing EAC3042 as
liste4d in your on line catalogue. Is it an OEM supplier bearing?
I would also like acatalgue and price list if possible. Thank you

See, that’s just unreasonable. You can pick up a rebuilt GM water
pump which includes a brand new very similar bearing, a new seal,
sometimes a new impeller, a lot of professional parts cleaning, and a
paint job for perhaps $30. I’ll be willing to bet that when/if we
actually get some dimensions for this bearing and/or a non-Jaguar
source, we’ll find that an identical bearing except that the shaft
sticks out BOTH ends instead of just one costs something like $20.
IOW, Jaguar is charging you $93 to saw the shaft off.
Do you have this thing out? Can you take some dimensions?
A few years back the Arbor Bearing on my trusty old Rockwell Table Saw
went out. Delta bought out Rockwell many years ago, and halted production
of replacement parts. Their customer service guy was kind enough to
suggest that perhaps I could go to a machinist and get a new one made if
I really wanted to keep that old antique. I went to a machinist, who took
one look at my part, and said “Take it to any bearing supply house,
they’ll have what you need… bring it back here, and I’ll machine it
for you”. Sure enough, I went to a bearing supply house, the guy behind
the counter took one look and said “Water Pump Bearing”… he took a
quick measurement, looked in a book, and in less than five minutes I was
out the door with a Water Pump Bearing of the appropriate size… The
machinist cut the shaft off of one end, after cutting the appropriate
“reverse” threads on the other end, and I had a brand new Arbor Bearing
for less than the price Delta quoted for a part they no longer stock.
You might want to give that a try.

Not yet as the car is in storage for the winter, but I am expecting via
mail, a spare complete assembly which I’ve just purchased online from a CDN
spec 87 VDP.

That arbor bearing didn’t cost you $112, did it? Even INCLUDING the
cost of having a machinist cut reverse threads. And for the Jaguar
idler pulley, no reverse threads required; you can do the required
machining yourself with a hacksaw.
This is what I’m talking about. If you have the old bearing in hand
and can take it to a place that sells water pump bearings, I can’t
see this issue being a serious problem. Nobody, not even Jaguar,
would devise a custom bearing in an oddball size for an idler pulley.
If someone finally does this, please report with the dimensions
and/or bearing numbers so it can go in the Book.
Hi All,
I have a fix that may suit some of you, One time when I had my car in the
Middle East the jockey pulley bearing went and with no chance to get one
from the local Jag dealer, I had to come up with a solution.
What I did was, find a Pulley from a rice burner the same dia as your
original with a center bearing then find a piece of tube the same dia as the
bearing and have a bolt welded to one end, fit the tube into the bracket and
mount the new pulley onto the bolt with a self locking nut and you should be
back in business!
I think I still have that old setup laying around if anyone needs a pic.
regards
