I have the front cyl at tdc, working on the intake pushrod. I've got it extended so that it is seated with no up and down play but still spins freely. With fuelmoto pushrods they have reccomended 4 turns. How much resistance should you feel at that point? I know it's hard to qualify over the internet but those turns have more resistance than I expected. What exactly is the pushrod pushing at that point? rocker arm? is it possible to do any damage? Got it all loosened off right now while I figure it out. Thanks!

 

You need to feel a little resistance.The lifter is nothing more than a pump.If there's any space in between it's going to be noisy.

 

Take a look at this video:

I don't know if it will help you or not.

 

After the four turns out and letting it set a few minutes, you should still be able to spin the pushrod. Basically you are tryng to set the bottom end of the pushrod right in the center of the lifter travel or some set them just slightly deeper to cut down on valve train noise.

 

at 4 turns out you will have a lot of resistance, but wiat 1/2 an hour and they again will spin freely as the lifter will bleed down.

 

The pushrod is pusing against the oil in the lifter body and oil doesn't compress. The only way oil can escape is back out the inlet hole in the lifter body; the hole is very small. Like others have said let that lifter bleed down to the point that you can rotate the pushrod between your fingers before you rotate the engine to adjust another valve. TDC should also be TDC on the compression stroke.

 

TDC on the compression stroke, ok, I am following the guideline on bigboyz site which says....

To Adjust the Pushrods....

Watch the rear cylinder pushrods or lifters.

Turn the engine over (by hand) until you see the cam overlap for the rear cylinder. That is when exhaust lifter is traveling down and the intake lifter is traveling up (closing the exhaust valve and opening the intake valve).

Once you find that for the rear cylinder, the FRONT cylinder will be on its compression stroke. You can now adjust the front cylinder pushrods.

Is that accurate?

Cheers

 

That should work. The thing is to adjust the pushrod when the lifter is riding on the base circle of the cams, not while the lifter is on the lobes.

 

ok, one pushrod in. bled down after 20 min, all good. now if i can just figure out how to get the clip back in.......

 

Getting the clip is not the fun part. Its worth getting a clip installer. If you don't then get a giant screw driver. Put the top of the clip into the head and slide the bottom part of the clip down the shaft of the screwdriver. Helps to put a little oil on the screwdriver. Push hard! Wear gloves. Bloody knuckes are guaranteed.
