Hi All,

Happy vetrans day. I need some help adjusting my pushrods on a 1979 80 inch, I have the hydrolic lifter and adjustable push rods.
Thanks,
Charlie

 

just do a search on here,there are a lot of pages on it,thats how I learned

 

take the lifter body apart -- use a small nail and stick it in the nipple -- drain ALL the oil do this a few times -- do not take any parts apart other than the normal 2 parts -- re-install adjust till it feels solid -- not where it opens the valve just the push rod wont move -- then back off 4 turns -- this way you dont have to wait till they bleed down..

 

Sometimes a previous owner will locktight the hydraulic unit in place and it can't be removed without damage. Then you will have to adjust it as per the manual and don't forget to let it bleed down before turning the motor over or you will bend the pushrod and probably the valve. The valve you adjust will be at the lowest position and it's oposite on the other cylinder will be at the highest point. Loosen it until you have some slack then tighten it until you have no movement then four more turns. Wait until it bleeds down before turning the motor over to do the next valve.!!! You will know its down when you can spin it between your fingers.

 

Damn where did you run across that kinda fubar ? Never seen loctited hyd. units yet thank god . Got a box full of beat to hell and sloppy fitting ones , don't think I've ran across a shovel that had one too tight .

 

Believe it or not a owner of a dealership told me they had problems with some of the late 70 models blowing oil by the hydraulic unit and that was their fix. I've run into a few of them held in by red loctite. One company offered a tool that expanded into the barrel of the unit and sometimes allowed you to get it out.

 

I can see it happening I've had some so loose I'd miced the insides of the lifter and then the insert bodies then wrapped them with stainless steel shim stock to take up the fit , worked pretty well for what it was .
