AXLE TAPPET ASSEMBLIES FOR BIG TWIN & SPORTSTER -
Jims offers you a choice of four different types of Big Axle
Tappet Assemblies. The first type is the Standard Style Mechanical
Tappet. The second type is the Standard Style Hydraulic Tappet.
The third type is the Powerglide Hydraulic Tappet and the fourth
type is the Hydrosolid Tappet. All assemblies listed are of
the Big Axle Roller design. The roller is designed around only
three working parts that have been improved for durability
and reliability. The Big Axle Tappet has a 27% greater wall
that reduces harmonic distortion for better tracking of the
cam lobe. In addition, the pin bearings have been reduced in
size to increase RPM for more precise tracking around the axle,
and the axle itself has been increased in diameter by 36%.
The simplicity of this new design is that the axle serves as
the inner race meaning the pin bearings and outer wheel rotate
around the axle and not on an inner race, eliminating all possible
movement. All tappet assemblies are sold each and include instructions.
Made in the U.S.A.

The Hydrosolid Hydraulic Tappet Assembly is the ultimate high performance/RPM
tappet available. The Hydrosolid performs like a hydraulic tappet
up to about 5500 RPM and then turns into a solid tappet. The second

horsepower. Hydrosolids will not pump up and allow your valves
to hit each other and can be used with hydraulic type or solid
type cams. (NOTE: Use with adjustable pushrods).
