Hey all,
As the title says I installed a new Indigo thermostat system, nice design. While I played with the cooling system, I removed the water pump to check it out. The pump looked pretty rough. I cleaned it up with a brass wire wheel. The grease cup was full but the nipple on the shaft end was broken & no grease was getting to the shaft. The shaft has grooves like a record(remember those??). I can see the shaft hole in the pump body is egged out and there is probably an 1/8" of shaft play. I tried calling MMI on Friday to get help & order a new MMI pump but they must have taken the day off....good on them
I guess my question is why my pump worked fine when it was cruddy but won't now clean. Tom at Indigo gave me some ideas to try. I ran the pump without the cover gasket; flipped the impeller, one end of the vanes are a little rounded; took the new sea strainer out of the system. Nothing changed.
I have some other ideas to get the system back to pre Indigo level. There is a bit more plumbing on the Indigo system & maybe the old pump can't quite make it.
Any tips or tricks you might have would be much appreciated. Is there a good way to bench test the pump?
Thanks
Steve
