2- 1953-'65 Panhead Stock Replacement Hydraulic Pushrod Kit

(Part 93-5091 and 93-5092)

NOTE: These kits are intended to replace the stock pushrods found in 1953-'65 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 (20 to 30 minutes or when pushrod spins freely) 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 procedure for rear TDC cylinder.
i- Replace spark plugs and pushrod tube clips. Start motorcycle and check for leaks.

3- 1953-'65 Panhead Solid Lifter Conversion Kit.

(Part 93-5081, 93-5082, 93-5083, 93-5084, 93-5058, and 93-5028)

NOTES:

These kits are intended for converting 1953-'65 stock style hydraulic lifters to adjustable solid lifters.

•

Panhead engines, 1953 & later, and 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.
