Purging Air from the HST Pump
WARNING
When refitting the HST pump after repair or re-
placement, be sure to purge air before starting
the operation. Failure to do so can cause injury
or death due to unexpected machine move-
ment.
1. Before installing the HST pump on the machine,
fill the servo control chambers with hydraulic
oil.
a. Plug the pilot ports (X1), (X2), (X11) and
(X12) temporarily.
b. Supply hydraulic oil through the servo pres-
sure gauge ports (M4), (M5), (M14) and
(M15) to fill the servo control chambers.
