Super “Powerglide™” Kit (Shovelhead)
✔ Shovel®"Powerglide™" Tappet Block Kits are capable of the highest rpm a
Harley can safely turn, at a valve lift of .700” and with the right valve
springs, valves, cam, oil, etc.
✔ Shovel motors can have all the hydraulic
benefits of the late EVO style
®
hydraulic system by installing JIMS Shovel "Powerglide™" Hydraulic Tappets.
✔ These kits will eliminate the total oil loss of the stock hydraulic units, No.
17920-53A.
✔ Billet Shovel Tappet Blocks with "Powerglide™" Hydraulic Tappets.
✔ Comes complete with instructions.
✔ Tappet block gaskets included.
These tappet blocks supersede lifter block No.’s 18603-80A, 18610-76A and tappet No.’s 18522-53A. Fits Shovel Big Twins 1953 through 1984. Use 1/4”-20
®
®
screws, JIMS No.1205, from late 1976 through 1984. Use 1/4”-24 screws, JIMS No.2406, from 1953 through early 1976. These blocks
are designed to accommodate a gross valve lift of .550” at the valves, leaving a clearance of .035” roller to block freeplay (Please note, if
using a cam with a higher lift, a simple modification is all that is needed).
®
All JIMS Billet Polished Tappet Blocks are made from 7075-T651 aluminum with a tensile strength of 83,000 psi, which is double the amount
of 6061-T6 aluminum and almost triple the amount of cast aluminum tappet blocks. These tappet blocks are machined to the center line of the
cam and hold to ±.002”. Also, the bores are held perpendicular to the mounting flange to ±.0002”.
®
At last JIMS has designed and engineered a completely new block kit for shovel motors, stock or performance application. This new kit has an
upgraded pushrod seat at a 3/8” diameter and a 5/8” lower seat. Lowering the pushrod seat will help reduce the severe tappet pushrod angle,
®
making JIMS new kit as close to an EVO tappet as possible. Kit comes with four Big Axle Tappets with new pushrod seat, one 1029-53F front 7075T651 tappet block polished, one 1029-53R rear 7075-T651 tappet block polished, pushrods, two tappet block gaskets and complete instruction
sheet.
Please read all instructions before starting this job.
Refer to H.D.® Service Manual for specifications and to remove tappets and tappet blocks.
Remove all old gasket material and keep all foreign material out of tappet block holes.
Wash pushrod covers and install new seals.
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.
6. Apply JIMS® Assembly Lube, No. 1226, to tappets and rollers. Slip tappets into blocks and install blocks.
7. With both blocks in place on case, install JIMS® Tool #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.
8. This is a good time to clean the tappet screen.
9. Locate the front pushrod and covers first. Apply JIMS® Assembly Lube, No. 1226, 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)
10. Extend pushrod adjuster 9 wrench flats or 1 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 locknut 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.

SHOVELHEAD VALVE TRAIN KIT
Shovel head owners, "clean up your act," with JIMS®
new valve train kit. This totally engineered valve train kit
will enable you to oil your Shovelhead top end like an
EVO.. You can remove your top end oilers because oil is
fed through JIMS® proven Powerglide tappets, then up
through work saver pushrods into JIMS® Roller Rocker
Arms. Tappets maintain oil pressure better, and they
improve the lubrication because oil is now pressurized
through the points of contact. Oil pressure to the top
end is controlled just like the proven EVO oil system.
This kit comes with super special Powerglide™ tappets
with an EVO style pushrod seat, special worksaver
pushrods, chrome tappet blocks, two tappet block gaskets, and an easy to follow instruction sheet.
Use on single cam only Big Twin 1966-84. (Note: Includes Aftermarket motors) ( Use quad seals for the best
possible oil sealant.)
Please read all instructions before starting this job.
1. Remove heads and rocker boxes from engine as per H-D® or Clymer Service Manual.
2. Remove rocker shafts from rocker covers by first removing rocker arm shaft screw and o-ring from one side,
then remove acorn nut and washer from other side.
3. Tap rocker arm shaft from cover being careful not to damage threads. Inspect shafts for wear and burrs,
replace with JIMS® # 17611-66B if needed. Remove rocker arm and spacer. Remove old gaskets. Check for
excessive wear at the valve stem tip and pushrod tips. Replace any valve train parts that are worn, bent,
broken, pitted or discolored. Keep in mind that excessively worn parts at the pushrod ends and valve stem
tips are an indication of wear at the valves and seats. This might be a good time for a valve job, and or new
valve springs ect.
4. Install JIMS® rocker arms with spacer. Use assembly lube on rocker shaft. Install shaft and tighten acorn nut.
Use a new washer.
5. Check rocker end play. See H-D® or Clymer Service Manual specs, adjust if necessary.
Instructions continued on page 2
NOTE: When installing a performance cam with high lift, you should always check for rocker arm to
rocker box clearance. This can be done with clay or machinist dye. Keep in mind all rocker boxes are
different due to casting differences. Minimum clearance .060. Remove material from the rocker boxes
only. Also, if you are using a valve spring with a large diameter top collar check for clearance between
underside of rocker arm to the edge of the top collar. Also check valve to valve at overlap (should have
at least .035" to .040"). Then check valve to piston to have at least .060". All this must be performed
with your valve train set with zero valve lash. If you have hydraulic tappets, adjust them to be solids
for the above check. Readjust tappets after check per tappet instructions.
CAUTION: Wear safety glasses. Excessive force may damage parts and tool. See JIMS® catalog for over 100 other top quality professional tools. The last tools you will ever need to buy.

SHOVELHEAD ROLLER ROCKERS
RATIO 1.50
By popular demand, JIMS® introduces roller rocker
arms for Shovelheads. Designed to reduce friction in
the valve train, providing more horsepower and less
heat in the top end. Cast from 4340 chrome moly steel
®
and heat treated. JIMS Roller Rocker’s feature a 660
bronze bushing fit to .0007” - .0012” for the best wear
resistance and oil control, along with a roller tip made
from bearing grade material to reduce valve guide
wear and valve tip galling. Other features include a
segmented parabolic pushrod cup which reduces friction at pushrod end and also puts the load on the outer
®
perimeter of pushrod ends, with full oil pressure at pushrod tip. Designed to work in conjunction with other JIMS
®
valve train components. Use JIMS No. 17611-66B Rocker Arm Shafts, or equivalent. These rocker arms replace
H.D.® No’s 17630-66A & 17375-66A.
1. Remove heads and rocker boxes from engine as per H-D®Service Manual.
2. Remove rocker shafts from rocker covers by first removing rocker arm shaft screw and o-ring from one side,
