Square Housings

Cylindrical Housings

IMPORTANT

The design of the Viscount II hydraulic pump upper and lower motor housings has been updated. The cylindrical 

design replaces the square housing design previously used. There is no performance change associated with this 

update. If replacement of a square housing is necessary, both the upper and lower housings must be converted 

to the cylindrical design as it is not backwards compatible. 

If replacement housing 16F140 is needed, you must order replacement housing kit 20B232 to upgrade system to 

cylindrical housings design. 

All instructions in this manual apply to both the square and cylindrical series of models, unless otherwise noted.
