1. Remove the left and right Drive Housing covers, see "Drive Housing Covers Replace-
ment" on pageî88.
2. Measure and verify that the first stage drive belt tension is within specification, see "First
Stage Drive Belt Tension Adjustment" on pageî52. If the belt tension is not within spe-
cification, re-tension the belt.
IMPORTANT: Adjust the first stage drive belt tension prior to adjusting the second
stage drive belt tension.
3. Use a 1/2" socket to loosen the two Generator/Brake assembly bolt nuts (left side) just
enough to allow assembly movement. Do not remove the carriage bolt nuts.
CAUTION:îMake sure that the two Generator/Brake assembly carriage bolts are
loosened before adjusting the second stage belt tensioner. The tensioner hardware
can be damaged and the belt cannot be tensioned if the Generator/Brake assembly
are not loosened.
4. Place the belt tension gauge onto the Second Stage Drive Belt midway between the
Generator/Brake pulley and larger Step-up Assembly pulley and measure the tension.
Record the measured belt tension.
