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.

UPDATE, I pulled the heads on no. 1 compressor and the valves were
fine. No broken rods on no. 2. Slight scoring of the walls but
nothing major. The customer said run it. Got the system leak free,
well tight as they say put the pump on second stage compressors
3,4,&5, and it pulled down to 400 microns in 8 hours, Got the pump on
1st stage comps 1 & 2 going to let run overnight and hopefully start
charging the old bitch in the morning. I recovered 250lbs of
refrigerant and the system requires approx. 485lbs, Im going to try
and talk the customer out of re using the recovered refrigerant
because I dont trust it. It leaked like hell all last year so im told
and I dont know for sure what condition its condition is in. Im sure
cost is going to be a factor. I have a week and a half in on this job
so far and my knees are talkin to me. :(
