9. Attach the pump to a suitable lifting device and remove all 5/8” bolts that hold the pump to the
PTO extension shaft.
10. Remove the pump.
11. Install the new pump using a suitable lifting device.
Before attempting to install the new pump, it is very important to check the porting configuration
of that pump; the ports on the replacement pump must be positioned the same way as on the
uninstalled pump. If not, proceed with changing the porting configuration of the new pump.
The replacement pump must be oriented in such a way to facilitate easy reconnection to the
hydraulic system and attachment to the chassis frame.
Go to page 263 to know how to change the porting configuration of the new pump; procedure
begins with Step 13 a.
NOTE: If the old pump had an o-ring on the front cap, the replacement pump must have a new o-ring
installed. Make sure this is done before installing the pump.
