Instruction Sheet For #2459, 2460 & 2461
Power Glide™ Tappet
Big Twin - Use on 1953-84
Pan and Shovel Models
Install tappets per H.D.® Service Manual
Use with JIMS® pushrods No.2404 for panhead or JIMS®2369 for shovel-
heads or H.D.® style pushrods #17904-66, or equivalent.
1. These tappets will work best in Jims® Tappet Blocks
#1095 (supersedes #18602/3-80A), with a run-
ning clearance of .0007-.0012.
2. Jims® Power Glide™ Tappet can also be run in H.D.® blocks, at a running clearance of .0007-.0012.
3.
Install lifters in tappet blocks with oil hole on tappet facing each other in the blocks.
4. Jims® Power Glide™ 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.
5.
With the Power Glide™ Tappet installed, start with the front tappet at the lowest point on the cam, extend the pushrod to zero lash (no
up and down play, this is not moving the hydraulic unit from snap ring down).
6.
Extend the pushrod adjuster 15 wrench flats if your pushrods have 24 threads per inch (H.D. pushrods® have 32 threads per inch),
17 wrench flats if pushrods have 28 threads per inch, 18 wrench flats if pushrods have 32 threads per inch, 24 wrench flats if
pushrods have 40 threads per inch, and 30 wrench flats if your pushrods have 52 threads per inch. Tighten locknut.
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 very important that the engine is not rotated while pushrods are tight. The pushrod will spin with your fingers after it has
bled off properly.
7. Recheck lock nut, close covers and install clips.
8. Repeat exact procedure on rear set.
9. Turn motor over several times to pump oil into the Power Glide™ Tappet or until the oil light goes out, or oil is returning to the oil tank.

CAUTION: Use motorcycle oil 20-50w at best and clean the tappet filter screen.
May also be used with 50w or 60w oil (See item E, below)
The following is sometimes mistaken for noisy tappets:
A. The most common being the clearance between cam gears and pinion gear (referred to as gear lash). If you did not change the cams at the time of installing this
kit and had no gear lash but a slight whine when motor was cold it is safe to say you are OK in this area.
B. Rocker arm end play .004” to .010” is good.
C. Oil pressure at normal operating temperature about 2000 r.p.m. should be 12-35 p.s.i..
D. Check valve to guide clearance.
E.
If using 50w or 60w oil you may have a ticking noise at cold start, this is normal.
