Adjustable pushrods ...

and hydraulic lifters are a combo I have no experience with . I seem to
recall reading here that they should be adjusted to about the middle of the
distance the plunger in the lifter moves . That is , if the lifter guts move
.200" , I should extend the pushrod about .100" past the point of initial
contact (with the lifter on the base circle of the cam , of course) . I gots
the lifters , and the pushrods . Just need to pick up the alignment tool and
make sure I have the correct 12 point socket .
It's ticking just a bit when hot , figger it can't be a bad thing to
replace 'em , since I have NO idee of how many miles they got . BSTS !
Shirley it's time for a drink ...

Yep. Easiest way I've found to do that is to get the lifter on teh heel
of the cam and tighten the pushrod up until it won't move. Wander
around for a little while, come back and take up the slack that's
developed while the lifter bled down. Repeat as necessary until no slack
develops. The lifter is fully bled then. Back off the number of turns
you need to give back half of the travel (depending on the thread pitch
of the pushrod), lock it down and move on to the next one.

Haven't had to replace lifters in quite a while. Are the HD's still big
axle types and are they still under $30 apiece?

I picked up a set of supposedly hi perf lifters on ebay . Finish is nice
and they look beefy , that's for sure . I did contact another purchaser
before I ordered these , feedback was they looked good enough he was using
them in a 117 inch build . Seems they were like 50 bucks the set . Nope , 65
bucks including shipping .
These are new in the plastic bags , so it'll be easy to adjust them - no
wait to bleed down . Also one helluva racket when it's first fired up .
Gotta remember to borrow the bolt cutter from work ... and get these soaking
in a can of oil the day before the install .

I don't know if they are "large axle", but the stock ones I got about a
month back were 29.95 per, less whatever loyalty discount your beloved
dealer offers. (I get 10 off everything for having spent over $300 there)

The spec for the SE adjustables is to go to zero lash, then 2.5 full turns
more. Mine is running quieter that they have for quite a while. I once
tried the Bleed-em-down-all-the-way-then-back method and it did not go
well, but then I'm not a real mechanic, so that doesn't mean much.

Don gave you the easy version of how to adjust push rods. If you don't
know the thread pitch, or like some of us are too lazy to do the math, backin'
off 11/2 turns will give you enough room for hydraulic pump up & plenty of
cushion.
If you have just a little ticking you might want to ask what the push
rods are made of. In EVO days the aluminum stock push rods were pretty quiet.
Then we'd change to some cool adjustables that were made of a harder material &
add some ramp & duration to the bump stick. It left us wonderin' why we
couldn't get all the noise out of the valve train...............Duh!

Dem bad boys are exactly .025 per turn . I had to source a 3/8-40 tap to
make a locknut that was missing (bored and retapped a gr5 5/16-24 since the
others were 1/2" on the flats). These came from an opened package from a
dealer on ebay (Harley dealer in Pa. IIRC) for a very reasonable price .
There's no tick when cold , and it's not loud when hot . I'll just feel
better KNOWING that I ain't about to spew needle bearings throughout my
motor . The PO kept a lot of records for parts and work , lifters ain't on
any of them ... and at 70k+ it's due for a second replacement set anyway .
Shirley , get Jinks and Spunky whatever they want offa the top shelf .

Good point. I hadn't even thought of that.

Not sure about the EVO, but on the TC there's a tool you can use to keep the
tubes outta the way while adjuting them pushrods. An old fashioned clothes
pin, the kind with the spring now have a place in my toolbox.

I useta carry four of 'em in the saddlebag of the Shovel ... I was
paranoid about adjustment cuz those wuz my first set of solid lifters . I
haven't even put the toolkit back on this bike since the rear suspension
mods , but then I've only been local so far .

I've used a bent paper clip and a rubber band to do that for, shit can
it be forty years?

Damn.

Good advice from the others, I'll just add that certain adjustable pushrods
will hit the bottom of the inner tube when running. Just watch for it and
trim the tube to clear if needed, especially watch the front exhaust. If
you need to shorten the tube, 1/4" is usually more than plenty.
