What is the purpose of the disk on my 89 vet water pump...looks like as my buddy called it a big frisbee, does it have to be there or not?

Starting in 1988, GM used an "improved" A/C compressor. The disk was added to smooth out compressor on/off cycling. When I owned a 1988, I removed it, and found no performance improvement. It did seem like the A/C cycling was not as smooth with it removed. The disk is heavy. It is easy enough to remove and reinstall.
i think it was added to eliminate what gm anticipated as teh belt slapping around when the a/c cycled "on"...i have an 88 and removed it also.......where in buffalo are you as i am from there?

I just happen to be in North Tonawanda this past weekend looking at a 1987 Z51 with 68,000 miles. I'm finding that C4s are selling way under their real values. So I'm out hunting for a 87-89. I really like the L98 engine for a daily driver.excellent!...town of tonawanda across the street from st. joes.
well, now that we know what maybe the "frisbee" does or does not do...should we remove it...seem to me and my mechanic that it is a lot of weight on the H20 pump??????
After all of your discussions and per my mechanic...the disk goes this weekend, not needed and l;ike you said better air flow and weight off of water pump...thanks
