Abstract
The “no tools” pump removal system comprises a bearing housing attached to the drive housing. The bearing housing has a hinged door that when opened allows removal of the pump pin and then the pump. The bearing housing is provided with a latch assembly and a handle. A safety latch retains the handle in place during operation and until it is desired to remove the pump.
