Lifters and pushrod questions
OK, so I put in some TW6-6 cams and used the SE Adjustable pushrods. I have been adjusting them slightly to try and get rid of what I thought was too much noise but with no success. I also had one loosen on me (my fault I believe).
I would now like to start from the beginning again and go thru the process again, but I think now that I have adjusted them I have limited the travel of the lifters (the hydraulic lift). So the questions are this:
1) If I pull the push rods and start over, do I need to charge the lifters to get the cups to the maximum throw? If I just loosen the lifters and adjust to 0 lash I would think I will be right where I am now.
2) Can I just remove the push rods and turn the engine over with the back wheel to pump up the lifter? Will enough oil be pushed into them?
3) I read in a few post away back, that the SE adjustables will rub or hit the tubes with high lift cams. I don't see how that happens since the lifters roll on the lobes and lift straight up. Is it due to the rock arm lifting higher and changing the angle?
Could this be the source of the noise? If so it sounds like tapered push rods would be the way to go.
Thanks

Not intending to hijack this thread but to bump it and see if some discussion can generate.
Seems push rod loosening up is a little more common then I would of believed did a little searching. It happen to me on Wednesday. I can not look at bike until Saturday.
What kind of damage can this do?
Should I replace push rods? Not sure I can trust it now.
In my mind I can re call exactly how I did each push rod and am surprised it come loose. But it must be my fault?

First of all, you don't need to worry about (1) If I pull the push rods and start over, do I need to charge the lifters to get the cups to the maximum throw) or anything else. Just follow the original manufacturers instructions and you will be fine. One thing I would suggest is that you clean the threads of the rod, nut and stud very well with parts cleaner and make sure it is evaporated before you start the install, and most important is to use locktight and give it enough time to set up. If you follow this step you will not have a problem with them coming loose like some others have .

Let me be clear, I am not having problems with the push rod adjusting nuts coming loose, I did on one but that was my fault (it came loose in about 5 miles and was due to I believe getting the bottom wrench on the nut and rod at same time). So I don't want this thread to be a adjustable rod bashing party.
The basic question is, if I want to readjust them do I need to recharge the lifters or will the plunger return to the top travel by itself once the load is taken off it?
The other question was on push rod rub, but I think I found that answer in an old thread, looks like it is possible with a high lift cam. But the TW6-6 seems to be a mild lift at .510 so I don't think this is a problem.
I may investigate the end play in the rocker arm that fireaxxe has posted about.

redhawk44 said no need to charge lifter in his above post. I am going to re do the one push rod on mine but I am unsure if I trust it.
I went about 80 miles before my push rod come loose. I am checking the one today but intend on replacing I think.

I have had the adjustables in for over 600 miles now and no problems after that first time. Just make sure they are tight and a dab of blue locktite on the top of the locking nut like redhawk said.
I just reread his post and he says no need, I was just wanting to make sure that the lifter cup will push back up when unloaded, but it seems he is implying that

It is my understanding that the lifter will fully inflate on it's own. There are springs in the lifter to bring the cups to full extension. The oil is a damper of sorts. So to me this means go gentle with a lifter not full of oil or you might not notice when you have zero lash as opposed to set into the travel of the lifter.

No. Just loosen the pushrod and start over.

I don't know anything about the adjustable push rods. However, I'm sure with the advise here you will get it worked out. When you do please post a review on how well you like the woods cams. These have been recommended to me by several people. Do to the shape they are suppose take away a lot of the lifter, pushrod or whatever noise the screamin eagle cams produce. Please keep us posted!
