Priming T/C Oil Pump

[m38inmaine]

I am trying to prime my transfer case oil pump, following the instructions in the TM. I can pull a steady flow of oil through with a suction gun but all I can get by manually actuating the pump is a dribble. Is this normal or should I be able to get a steady flow manually?

Thanks

It's only a dribble. The stock and diameter of the little piston can't pump much. The dribble drops down inside on the top of thr gear, this spreads as the gear turns.

That's good to know. I thought my pump was shot so I ordered another one from Red River. Oh well, looks like I have a back up pump.

Does this need to be done if machine has been not run in long time or only if u drain all oil out ?

Id add the Lucas if you've never done it before and always if you drain. The main thing is to insure it supplies the oil to those gears, and it's
such a bear to get the dog house up just to check.
