JIMS 1807 - Manual

Use with JIMS ® new No.1043 Twin Cam Tappet Cover when using any stock to mild lift cams.
NOTE: Powerglide II must be adjusted in a cold motor only. If you are unfamiliar with lifter
adjustment, seek professional help. Otherwise serious engine valve train damage will result.
NOTE: The JIMS Powerglide II tappet includes design parameters that may or may not
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: JIMS Powerglide II Tappets are assembled with a small amount of oil to ease in the
tappet adjustment process. If the pushrods you are using are adjustable, proceed as follows:

blocks at the same time follow those instructions.
Note: As you are preparing the engine for the installation of the new Powerglide II, put
all 4 tappets in a clean container (plastic bag) filled with clean H/D 20-50 w oil to cover
tappets, let them set for 20 minutes.
2. Place the front piston at TDC compression.
3. With all four Powerglide II tappets installed, start with the front intake pushrod,
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 15 hex wrench
flats, tighten lock nut, to 15 ftlb of torque.
Note: This will move the adjusting screw down, pushing the hydraulic unit down it’s bore
.1035”, this will or may make the pushrod tight which will bleed the hydraulic tappet.
Note: It may take 5 to 15 minutes to bleed off completely.
Caution: Do not rotate the engine until you can turn the pushrod or pushrods with your
thumb and forefinger.
CAUTION: If you cannot turn pushrod with your fingers DO NOT rotate engine.
5. Repeat exact procedure for the next three pushrods, making sure to be on the
lowest position of cam for the tappet you're adjusting.
6. Tighten lock nut, to 15 ft.lbs. of torque for all 4 pushrods.
