GEAR RATIO TABLES
7.92 C.D. Chaincase Jackshaft RPM / MPH
The following tables show the acceptable upper and lower
gear combinations for the 7.92 C.D. (EDGE) chaincase
along with the corresponding drive chain.
The MPH is a mathematical number and would occur

(spinning at the same RPM).
To prevent premature gear, chain and/or tensioner wear
do not install gear/chain combinations that are not listed
in the table.
