Clutch and Driveline Considerations:
When installing any performance engine you should consider upgrading your clutch and inspecting or replacing your Primary Chain and
adjuster. Increased power levels and aggressive riding styles can cause stock or worn components to fail or work poorly and they may need to
be upgraded. Ultima
®
recommends Midwest part#96-730 high performance clutch for use on 98’-06’ HD
®
chassis & Midwest part#96-731 for
use on 90’-97’ HD
®
chassis. For custom applications, Ultima
®
recommends using industry proven Ultima
®
belt drives.
Primary Belt Driv
e Considerations:
When installing belt drives on Ultima engines it is recommended
that RTV silicone be applied behind the stator where the casting
meets the steel liner & between the crankshaft splines & the rotor
spacer. Be sure to clean area thoroughly beforehand to insure
adhesion & curing of the silicone. See Fig 1. & Fig 2.
After applying the silicone. Install the stator onto the motor case. It
is also recommended that a liberal amount of blue loctite (med.
Strength) be applied to the stator bolts. See fig 3. & 4.
