Push Rod Adjustment
 

I hope someone can help me. I have had a 98 Ultra for a copuple years and its claimed to have a stage II kit installed, minus the heads. It does have adjustable push rods, and hydraulic lifters. It has been making a washing machine noise and has been getting worse. I have taken the primary all the way down and found nothing out of the ordinary, I have traced the noise down to the lower end of the motor. So now I have it torn down to the cam and lifters. I noticed upon disassembly that the push rods were spinning freely when the pistons were at TDC. I thought this was kinda strange since it has hydraulic lifters. My question is when I re assemble the push rods how much preload do I put on them, 1 turn, 2 turns ???? I just don’t know. I don’t want to bend a valve in the process of guessing. I have looked on line till I’m cross eyed and would appreciate any help you guys could send my way.

First you need to find out how many TPi the pushrods are. From there we can tell you how many turns you need.

It has a 40 tpi adjustable push rod.

Those riveras? 4 complete turns to start, if a little noisey, add another turn at a time...

Make sure the pushrods spin in you hand before going from one cyl to the next. Do this on the cams base circle(per cly) as well.
