S&S Cycle Pushrod Kits and Travel Limiters (all) - Manual (Page 4)

i. Repeat above procedures for rear cylinder.
j. Replace spark plugs and pushrod tube clips. Start
motorcycle and check for leaks.
2. 1966-'84 with hydraulic lifters.
(Part 93-5070 & 93-5071.)
NOTE: These kits are intended to replace the stock pushrods
found in 1966-'84 engines. These kits require the stock-type
adjusting screws, which are not included.
a. Remove pushrod cover clips and lift cover
assemblies to view lifters.
b. Remove sparkplugs and rotate engine until front
piston is at the top of its stroke, with both front
lifters at their lowest position (TDCC – top dead
center, compression).
c. Loosen front lifter adjusters and remove pushrod
and tube assemblies.
d. Clean and inspect pushrod tubes. Replace all cork
and/or O-ring seals. Apply a light coat of engine
oil to O-rings.
e. Install stock-style adjusting screws & locknuts
into pushrods.
f. Insert new pushrods through tube assemblies and
install in appropriate positions.
g. Extend adjusting screws to remove lash in pushrods.
Compress hydraulic unit in exhaust lifter 4 complete
turns (24 flats) and tighten locknut. Allow sufficient
time for lifter to bleed down (5 to 10 minutes)
before adjusting intake pushrod.
Failure to allow hydraulic unit to bleed down before rotating
engine or adjusting the other pushrod could result in valve-
to-valve contact and serious valve train damage. Lifters are
bled down when pushrod can be turned with fingertips.
h. Repeat above procedures for rear cylinder.
i.
Replace spark plugs and pushrod tube clips. Start
motorcycle and check for leaks.
3. 1966-'84 solid lifter conversion kit – adjustable lifter
(Part 93-5068 and 93-5062.)
NOTES:
●
These kits are intended for converting 1953-'84 stock-style
hydraulic lifters to adjustable solid lifters.
● Shovelhead engines with solid lifters should have tappet
block hydraulic lifter oil feed holes plugged to prevent
excess oil escaping above lifters and filling pushrod tubes,
causing potential oil leaks. Thread 8-32 tap into oil feed
passage from gasket surface of tappet block until tap end
just starts to enter lifter bore. Plug hole with an 8-32 x
3 ⁄
16
"
set screw. Repeat for other tappet block.
● If hydraulic lifters are to be reinstalled, plugs must be removed.
Restricted oil flow to hydraulic lifter assemblies causes lifters
to operate with improper oil pressure which may damage the
lifters or other valve train components.
a. Remove pushrod cover clips and lift cover
assemblies to view lifters.
b. Remove spark plugs and rotate engine until front
piston is at the top of its stroke, with both front
lifters at their lowest position (TDCC – top dead
center, compression).
c. Loosen front lifter adjusters and remove pushrod
and tube assemblies.
d. Clean and inspect pushrod tubes. Replace all cork
and/or O-ring seals. Apply a light coat of engine
oil to O-rings.
e. Remove tappet block and perform plugging step
detailed in above note. Remove hydraulic unit
from tappet and replace with solid lifter adapter,
adjusting screw, and locknut assembly.
f. Insert new pushrods through tube assemblies and
install in appropriate positions.
g. Extend adjusting screws to remove lash in pushrods.
Adjust to be able to spin pushrods with fingertips
with a slight drag, and tighten locknuts.
h. Repeat above procedures for rear cylinder.
i. Replace spark plugs and pushrod tube clips. Start
motorcycle and check for leaks.

93-5080)
NOTE: These kits are intended for converting 1953-'84 stock-style
hydraulic lifters to non-adjustable solid lifters.
a. Remove pushrod cover clips and lift cover
assemblies to view lifters.
b. Remove spark plugs and rotate engine until front
piston is at the top of its stroke, with both front
lifters at their lowest position (TDCC – top dead
center, compression).
c. Loosen front lifter adjusters and remove pushrod
and tube assemblies.
d. Clean and inspect pushrod tubes. Replace all cork
and/or O-ring seals. Apply a light coat of engine
