Smog Air Pumps..

[Jon Pike <jhpike@domain.elided>]

Well, curiosity might have gotten the better of me again..

I have the air pump off our 77 Spider.. turning it by hand makes the 
most obnoxious rubbing and scraping noises.  So I thought I'd take a 
look inside to see if something was fixable/cleanable/evaluate if it 
still is workable..

After a major fight with one last bolt that didn't want to go..  I 
discovered two pins driven from steel plate to aluminum housing.. got my 
new punch set out and started hammering... to discover that one needs to 
have the pulley off (I think) to get the parts apart.

So, lacking a large vise to hold the critter with while I try to get the 
big 21mm or so nut off the shaft (nope, removing the pulley isn't good 
enough) I quit for the evening..  hoping my separating the case 2-3mm 
and feeling the innards locking together rather than sliding out didn't 
damage it worse than it already might be.

Anyway..  wondering if any Digesti have some knowlege of these pesky air 
pumps.. how to tell if they are useable and where to get replacements if 
not. I have to put a working one on for my smog test, which is waiting 
till I get the engine fixed up and back together.

Interesting note.. I was surprised to see the manufacturer of the pump: 
Nippondenso!  Unfortunately, I can only see half of the model number on 
the label..  Hopefully someone can supply the rest,  and tell me "75-82 
Toyota Celica" or some such to look for in a junkyard, if I've wrecked 
this one.  ;-)

TIA..
