**Two of the plastic bushings must be furned down from 1.500" to 1.275"
The Main Shaft outer gearcase plastic bushing must be turned down from 1.500" to 1.150" to accomodate the housing and Main Shaft Seal CR 12330 (Any machinist can do with a 1.5" chuck).


Inspect bearings for condition, if OK they do not have to be replaced.

NOTE: the Warn 5687 does not have a drain plug for the gearcase! Drill and tap the bottom of gearcase inbetween the two main housing bosses for a 1/8-27 NPT drain plug.
