CAUTION: Before assembling or performing any secondary operations, please carefully read the "Application Hints" at the beginning of this section.
NOTE: These worm gears are profile shifted except the 25-tooth gear.
NOTE: Allowable torques shown in the table are the calculated values according to JGMA Standards 405-01 when the worm is rotating at 600 rpm, The table below shows the allowable worm gear torques at selected worm speeds.
NOTE: The shaft O.D., S, has the tolerance +0.2/+0.1 except where ground +0.40/+0.35.
NOTE: Please avoid secondary operations that affect the strength of the joint between CAC702 and FC200. Also, there may be space in the casting between the two materials, but it will not effect the joint strength.
