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
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:

. 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.
