Air Con compressor pump repair

Hello all,

The air con compressor on my 1983 110 V8 SW (originally exported to the
UAE) seized on me last year, necessitating the drive belt to be cut. It
has sat there forlornly ever since, until yesterday when I finally took
a look at it. Rather than the pump unit being seized (as I had
thought), it was the drive pulley - the pump shaft moves freely. There
is an electromagnetic coil which pull s the drive shaft clutch onto the
pulley when activated, and this seems to have short circuited just
before the failure (I was getting blown fuses), and then it wound itself
around the inside of the pulley. I have removed all this, and it just
needs re-assembling. Here is my dilemma!

1) what is the likelihood of getting service parts for this? The make
is Seiko-Seiki, and that's about all on the body except for the
refrigerant (R12) and lubricant.

2)If I can't replace the electromagnet, what's the best way of
permanently attaching the pulley to the drive shaft (I ran the thing
almost continuously anyway)

2a)How do I get ball bearings back between the grooves on the pulley and
the body?

3)If none of the above are feasible, what other air con pumps would work?

Ta,
Stuart

Pretty damned good. The clutch assembly should be a fairly standard one
that any good automotive aircon parts distributor should carry.

The best way is not to - just because it's turned on doesn't mean the
clutch is engaged so it doesn't actually run continuously. Summat will
overpressurise and do itself a mischief if you try that.

Buy a new twin row bearing, and they're fecking expensive for what they
are. That said, a new clutch assembly will come ready to bolt on and go.

Go and see a specialist - there should be plenty that will mount up the
same.

Assuming that it's original fit - then all the parts on on our
site at:

Get in toutch if you need prices.
