Alternator pulley diameters...

Gave up thoughts of refurbing alternator: at 150,000 miles thought
replacement was sensible rather than new brushes/regulator, so bought a
recon at local spares place.

They didn't have an identical unit, so fitted a Ford one which looks
almost identical (clearance hole instead of tapped for the adjustment
bolt otherwise the same), BUT the pulley is larger, about 1/3 bigger
diameter than the original. I tried and couldn't undo the nuts to swap
them over, so fitted it anyway.

Seems to be fine, but was this sensible? I'm assuming the alternator RPM
will be about 1/3 slower, but shouldn't matter much above tickover as
the regulator'll just be working less hard.

What does the team think?

Regards,

Simonm.

so long as you haven't got the kind of rev counter that connects to the
alternator, it should be fine. If you get problems with not enough output
then you can always change it later.

The pulley nuts are a bit of a sod sometimes. I grip the pulley in a vice,
meself, which isn't always good for it.

Thanks for the reassurance...

....on two counts (it's not just me then!). I stopped when I was likely
to bend the Allen key. I must get some of those nice ones that fit
impact screwdrivers and thus socket sets.

Cheers,

Hold the pulley with a leather glove and use an air impact wrench on the
nut - it'll undo really easily.

I tend to forget that a lot of people on here don't have such tools - I
had 6 at last count (1/4", 3/8", 2x1/2", 3/4" and 1" drive).

I thought leather gloves just came in S / M and L

My impression was "one size fits nobody".

I've finally found some decent welding gloves to suit my 10 year old son
- it's school holidays here at the moment and he's commandeered the MIG
to make "stuff" with. He's just about finished some wrought iron gates
for a mate of mine - my design, but all his work cutting and welding
them. I'm quite impressed with what he's done but my plans for the day
now have to include dropping them off to be galvanised.

Brilliant.

Does he use an ordinary mask or one of the 'electronic' ones? Interested
because my twelve-year-old daughter is showing an interest (from a
distance behind a shield!).

He and I both have electronic ones - he's got my new, very expensive one
because it's better fit on the smaller head and is a lot more reliable,
and I've got an older cheaper one that's due for replacement as it fails
to darken from time to time.

Kids who are going to weld need:
Spark resistant overalls - heavy cotton or better yet pyrotex.
Leather workboots.
Thick woollen socks.
Really good havey welding gloves.
An automatic helmet.
Scads of suntan lotion.
A watering can of water nearby for when the inevitable happens.

The gear for them should be better quality than your own (if possible)
as they get burnt much more easily than adults. My son also wears a
welders cap to keep the hot bits out of his hair - he reckons the
burning smell is gross.

not as bad as grindersparks going in yer ear, mind.

actually, a hat is a good plan, stops sparks going down the back of yer
neck.

oh and BTW, a tip for all you wannabe welders out there - sandals are not
the best footwear.

and I agree about the suntan lotion, you can get a nice sunburn from an arc
welder.

Automatic mask very good if you can wear the cost, either that or be *very*
careful to make sure they don't look at the arc.

I believe there are eyedrops to be had for "arc eye", and laying in a supply
might be a cunning plan if possible - however careful you are, sooner or
later someone gets a flash in the eyes, and it can be pretty uncomfortable.


and finally... things that've been welded are hot!

When I forget and some one asks "Was that hot" I just reply with "No, very
heavy"!

understatement, exchanged my dynamo last year and the motor factors very
kindly broke my 2a pulley saving me the bother

It took ages to source another one
