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, perform plugging step detailed in above note, and then reinstall tappet block and tappets.
f- Reinstall tappet block and tappets.
g- Insert new pushrods through tube assemblies and install in appropriate positions.
h- Extend adjusting screws to remove lash in pushrods. Adjust to be able to spin pushrods with fingertips with a slight drag, and tighten locknuts.
i- Repeat above procedures for rear cylinder, this time bringing the rear cylinder to TDCC (top dead center compression.)
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.)
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 (20 to 30 minutes) before adjusting intake pushrod. Pushrods must spin freely
with fingers.
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, this time bringing the rear cylinder to TDCC (top dead center, compression.)
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, perform plugging step detailed in above note, reinstall tappet block and tappets.
f- Remove hydraulic units from tappets and replace with solid lifter adapters, adjusting screws, and locknut assembly.
g- Insert new pushrods through tube assemblies and install in appropriate positions.
h- Extend adjusting screws to remove lash in pushrods. Adjust to be able to spin pushrods with fingertips with a slight drag, and tighten locknuts.
i- Repeat above procedures for rear cylinder.
j- Replace spark plugs and pushrod tube clips. Start motorcycle and check for leaks.
4- 1966-'84 Solid Lifter Conversion Kit – Adjustable Pushrod
(Part 93-5014, 93-5015, 93-5016, 93-5063, 93-5067, & 93-5080)
NOTE: These kits are intended for converting 1953-'84 stock-style hydraulic lifters to non-adjustable solid lifters.
