WHERE DO'S THE IDLER SHAFT ON THE HYD PUMP ON THE 620 GET IT'S OIL FROM, GOT ONE THAT IS RUNNING DRY AND CAN'T FIND ANY OIL PORT TO FEED IT--THANKS

Just splash and a little trough formed by the gasket for the pump.
If you use the hyd. a lot then I'd drill the gov. case there is a bump there where the pin bottoms in (IIRC) and add a fitting and tee into the oil line going to the gauge. I seen it done before and also did it myself.
The idler pin should already have a hole drilled thru it to this end.
