6. Check rocker arm to rocker box clearance.
7.
Remove the overhead oil line fitting (H.D.
®
#63526-57) from the front and rear rocker covers and crank
shaft. Install the four plugs provided in this kit. Use sealant on threads.

®

10. Wash pushrod covers and install new seals.
11. JIMS
®
"Powerglide™" Tappets are assembled with a small amount of oil to ease in the adjustment. This
way you will not have to bleed down the tappet at the time of final adjustment.
12. Apply Assembly Lube, to tappets and rollers. Slip tappets into blocks and install blocks.
13. With both blocks in place on case, install JIMS
®
Tool No.33443-84. (If your case has 1/4-20 mounting
holes, lube tool and screw into the tappet screw hole to center block into case.) Tighten to 30 in/lb.
Install the other block the same way. Remove tool and install last lubed screw and finish torquing to 120
in/lb in a criss-cross pattern at 30 in/lb increments.
14. This is a good time to clean the tappet screen. Use JIMS tool No.2233 to remove screen plug.
15. Locate the front pushrod and covers first. Apply Assembly Lube, to top and bottom ends and threads of
pushrods. (Note: Front and rear exhaust pushrods are the longest.) With the front exhaust cam at the lowest
point, adjust pushrod with thumb and finger just until you eliminate all up-and-down free movement.
(NOTE: Do not take up more than the free play of pushrods)
16. Extend pushrod adjuster 7 wrench flats or 1.2 turns. To do this hold screw with a 1/4" open end wrench,
while turning pushrod with a 1/2" open end wrench until you have completed the adjustment. Tighten
lock nut to pushrod with two open end 1/2" wrench.
IMPORTANT NOTE: This adjustment will make the pushrod tight, which will bleed the hydraulic lifter. It will take 10-
15 minutes or longer to bleed off. It is important that the engine is not rotated while pushrods are tight. The pushrod
will spin with your fingers after it has bled off properly. Tighten lock nut. Recheck, close cover and install clips. Repeat
exact procedure on other pushrods. Turn motor over several times to pump oil into the "Powerglide(tm)" Tappet until
the oil light goes out, or until oil is returning to the oil tank.
