NOTE: FOR USE ON ADJUSTABLE PUSH RODS ONLY.

Use with JIMS new No.1043 Twin Cam Tappet Cover when using any stock to mild lift cams.
NOTE: Hydrosolid®II must be adjusted as a solid lifter in a cold motor only. If you are
unfamiliar with solid lifter adjustment, seek professional help. Otherwise serious engine
valve train damage will result.
NOTE: The JIMS Hydrosolid
affect your oil pressure. These performance tappets incorporate an “oil hole” to feed the
tappet roller, axle and cam assembly. In test, JIMS has seen a slight drop in oil pressure
ranging from 0-3 lbs psi. It is up to you, the mechanic, to confirm adequate oil pressure
before and after installing these tappets.

Note: As you are preparing the engine for the installation of the new Hydrosolid® II, place
all 4 tappets in a clean container (plastic bag) filled with clean H-D
tappets, let them set for 20 minutes.

2. Place the front piston at TDC compression position.

3. With all four Hydrosolid
making sure tappet is at the lowest point on the cam.

4. Extend the pushrod adjuster screw to zero lash, you will be making the pushrod
longer (no up and down movement, removing all free play without pushing the
hydraulic unit down). See pushrod adjustment chart for your particular pushrod.
Example: If your pushrods have 24 threads per inch extend pushrod 5 hex wrench flats.

Note: This will move the adjusting screw down, pushing the hydraulic unit down it’s bore
.0345”, this will put the hydraulic unit about .014” from the floor of tappet. What we are
looking for is the hydraulic unit resting on the floor of the tappet.

(This is just a starting point, the adjuster screw may need to be extended or shortened if
the adjusting screw was either adjusted too far or not enough.)

This adjustment will bleed the Hydrosolid
longer to bleed off oil pressure. What we're looking for is a pushrod that just barely turns
with your fingers. If after 15 minutes, if the pushrod still turns easily, (with your thumb and
forefinger) extend the pushrod until you can just barely turn pushrod with your fingers. If
you can barely turn the pushrods with your fingers and the Hydrosolid
lowest point on the cam, then they have been adjusted properly.

CAUTION: If you cannot turn pushrod with your fingers DO NOT rotate engine.

Note: You can check your adjustment for all 4 tappets by performing the following: With
the rear wheel safely off the ground (bike tied down), shift bike into the highest gear, have
a helper rotate the rear tire forward just enough to see the front intake tappet start its
move up in its bore (only allow the tappet to move up it’s bore .100”, almost the thick­ness of a nickel). Stop the rotation of rear tire and have helper rotate the rear tire back­ward just enough to see the front intake tappet start the movement back down and then
back up it’s bore no more then .100”. As the tappet is moving up and down in it’s bore
(from the rear tire being rotated back and forth) you will need to be trying to turn that
pushrod with your thumb and forefinger. If you find any free movement (turning) of the
pushrod, take up this freeplay (by making the pushrod longer with the adjusting screw)
until you can barely turn the pushrod with your fingers.
Do the above Note for the other 3 tappets.

6. Repeat exact procedure for the next three pushrods, making sure to be on the
lowest position of cam for the tappet you're adjusting.

1. New motors, after the first 50 miles (at time of first oil change), check adjustment
of pushrods. You should still be able to turn them with your fingers, if not, you will
need to loosen the pushrod until it can be moved.

After 200 miles, readjust if needed and as needed until all your motor parts are seated.

3. Recheck as
