Adjustable pushrods in unfired engine
I need to adjust the pushrods in my engine.
I have new johnson hylift lifters. I did soak them for a while before installing.
this engine hasnt been fired yet, so there has been no oil flow through the engine. Is there any special procedure when this is factored in? Or do just follow crane's instructions for adjustment since the lifters are going to have to have the oil I soaked them in bled down anyway?

Also, the best way to get oil into the lifter before install is with an oil squirter can thing, with the trigger, into the side hole since that's the way the check valve works. Soaking them don't do **** but get them oily. Even if you fill the lifter it's still not "pumped up" because you can still push the plunger down with your finger. It's harder, but still free. Doing this makes the clatter at first startup much shorter though.
And, when you get the lifters installed if you still have the top end off I like spinning the crank a few dozen times by manually lifting the rods up and down. The oil pump does its job and fills the lifters the proper way. When you see oil come out the hole in the top of the lifter where the pushrod goes, she's as full as she'll get.

Always they were noisy with the DM 530 cam .
If you got away with .060 I think I will try it as I have cast iron.

So you guys are saying the Johnson's like a little looser push rod adjustment than some other lifters?
Where do I take that measurement? Exscuse my ignorance on this, never had a hydraulic drivetrain harley, especially with adjustable push rods

I can only tell you what J Hilift told me on the phone
preload of .030
He said theirs is different than others.
With that, I think there are two styles of J.Hilifts, AFAIK
So, in the in the end, it is not looser just the preload less.
Most Hyd lifters will ask to be centered which is at about the .100 thou mark
My word is not law here..
Do feel free to call them Monday if you are not sure and post what you find out.

I used to have a chart here that showed all the height difference .'
Of course, Al is going to grow much more than steel or cast.
I am sure Mattbastard is correct in the above post.
Make sure when you talk to J.Hilift you explain what you are working on, IE not a chevy
