Thanks WWDiesel,

In the vein of "...if at first you don't succeed, get a bigger hammer..." I got it off. A shot of whiskey and some lessening of my inhabitations, the parts came apart much easier.

I have a 5-cylinder pump with a good coil but it doesn't fit. The central hub mounting is not the same diameter and the pulley does not fit overtop the coil. Bummer. Tomorrow or Tuesday I'll get a new one.

Dean.

Today's job is replacing the AC pump magnetic clutch coil. Attempting to remove the front plate but having problems. Any recommendations out there?

This is the style of pump we have, although mine is a different manufacturer.

The entire assembly is similar to this drawing, including a single machine bolt in the center. That came out easily.

The part number on the clutch is MC247300-022.

The method to remove the clutch plate is to pry it off with flat blade screwdrivers. Mine is stuck too well and not coming off. I've soaked it with penetrating oil and heated it with propane. Still no joy.

I'm a bit shy about using too much power into the prybars.

Finished the AC clutch magnetic coil replacement. I sure took the long way around....
- Recklessly ordered a part from eBay that was actually the wrong part. ($60 down the drain.)
- Checked all the auto parts places in town and none could get the right part for my non-Santen pump.
- Then I remembered I still have access to the *other* engine at the local machine shop.
- Found and harvested the correct coil and it works!

Feels good to get past that part of the reassembly. Tomorrow I'll install the radiator and start up the beast.

Dean.
