A hydraulic pump is disclosed. The hydraulic pump may have a first fluid section (12), a second fluid section (14), and an input shaft (16) extending through the first fluid section and the second fluid section. The input shaft may have a first end (44), a second end (46), and a mid-portion (48) located between the first and second ends. The hydraulic pump may also have a first bearing (30) configured to continuously support the first end of the input shaft, and a second bearing (32) configured to continuously support the second end of the input shaft. The hydraulic pump may further have a third bearing (56) configured to intermittently support the mid-portion (58) of the input shaft. |
