Been working on a chiller fixing leaks with 5 six cly Carlyle's on it. O6EF's 299 310 compressors pretty good size. Pulled the top head off number two compressor to replace a leaking gasket and my spider senses started tingling so I pulled the head off of the left bank. The valves were broken and the tops of the pistons were pretty mealed up. Tomorrow Im going to pull the other head and insp the valve plate on that side, roll it over and insp the cylinders and check to make sure no rods are broken and do the same for number one. They are in tandem and for the first stage. The other three compressors are for second stage. Last summer I guess they were always pumping ref to the old gal because of all the leaks and im thinking who ever did it slugged them with liquid and as you know these compressors dont tolerate much abuse and thats what took out the valves.
My question is if the cylinder walls look ok and no rods are broken and it rolls over ok would I be ok just replacing the valve plate? I think it would be ok. What do you think.
