S&S Cycle Pushrod Kits and Travel Limiters (all) - Manual (Page 8)

a. Remove sparkplugs.
b. Bring piston to TDC on compression stroke in
cylinder to be adjusted. Normally both tappets will
be at their lowest point of travel.
c. Extend pushrod until it contacts the hydraulic
piston assembly in the lifter body, then extend
pushrod an additional four complete turns, until
piston assembly is in contact with HL

T spacer and
the valve is lifted off of its seat. If tappets contain
oil, as when pushrods are readjusted after engine
has been run, or if all oil was not removed during
installation, allow at least 10 minutes for piston
assembly to bleed down.
d. Loosen pushrod adjustment until pushrod can be
rotated with the fingers with slight drag.
Continue loosening (shortening) pushrod one full
turn (6 flats).
NOTE: Shortening adjuster an additional six flats or full turn from
zero lash often results in quieter pushrod operation. This provides
additional travel for the hydraulic piston assembly, which can
improve the ability of the hydraulic unit to maintain zero lash
under normal operating conditions.
e. Tighten lock nut.
f.
Follow the same procedure for all four pushrods.
NOTE: Perform this operation on one cylinder at a time. Do not
turn engine until pushrod adjustment is complete, and pushrod
can be spun with fingers.
Turning engine while valve is held off the seat could result in
valve to valve or valve to piston contact and serious valve
train damage.
