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 port configuration on
that pump; the ports on the replacement pump must be positioned the same way as on the old
pump. If they are not, proceed with the indexing of the new pump.
The replacement pump must be oriented in such a way to facilitate reconnection to the hydraulic
system and attachment to the chassis frame.
Go to page 92 to know how to index 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.
