Abstract
A gearbox for an engine-driven mechanism comprises a gearbox housing having opposing walls. A first bearing bore is defined in one of the opposing walls and adapted for receiving an input shaft. A second bearing bore is defined in the other opposing wall and aligned with the first bearing bore. Each bearing bore mounts a bearing for supporting the input shaft which extends through the first bearing bore and into the gearbox. The second bearing bore includes an associated transparent and/or translucent lens to define a sight window for monitoring the level of oil in the gearbox. A sight window of this nature is particularly well suited for retrofitting older gearboxes which lack a sight window.
