If you have a Packer Hyd. Motor on your Wrecker you need to add a case drain to it.
I have had to have my motor rebuilt two times now. the second time I was asked if I was using the case drain on the motor and I did the deer in the head lights thing. LOL
When you blow a seal it will fill up the winch gear box with Hyd fluid and it wills start
draining out of the winch drum holes. Makes a big mess.
The old type of Hyd. motor does not have a drain port.
I talked to two other guys that know about hyd motors and they said the same thing, you need to
use the drain.
I guess when the Military went to the newer Packer Hyd motor they did not add a case drain.
There is a 1/4 npt on the bottom of the motor and that needs to ran back to the Hyd. tank.
What I did was drill and tap the return fitting coming out of the tank and added the return there. I also added a 5psi check
valve to the return. see pics.
