Oil pump should be assembled in the following order.. Fat gerotors, plate, wavy spring, plate, thin gerotors..

Yup, this is what happened to me as well. Wound up shattering the gerotors and had to purchase a new oil pump.

You'll like those 509's when you get it back together. I ran them for a couple of years in my Deuce (also an 88)...Tons of mid range torque, and a nice lope.
Here is what mine sounded like with the 509's

It was the oil pump once I opened it up and I corrected the problem put it back together and its great! Love the cams. I used the S&S adjustable Pushrods and S&S lifters. I used 21 flats on the adjustable rods and the valves seem noisy still. Should I put a couple more flats on it? 21 equals 3 and a half turns.

Yep... I have a set of S&S cams sitting here waiting to install in my Rocker. The instructions with the cams say "S&S adjustable pushrods have 32 threads per inch, and 24 flats (4 full turns) will place the pushrod in the optimal position of the stock tappet"
