394 oil pump ?
« on: November 21, 2013, 07:43:55 pm »
Got a 394, used but new to me, I fired it up and its pumping oil rather quickly.  I turned the screw all the way in and it still pumps to much.  Any help would be great, as far as whats going on here.

Thanks.

Adjustment of the oil pump
The oil pump is adjustable. Adjustments are made by
turning the screw using a screwdriver or combination
spanner. The machine is supplied from the factory with
the screw set to position 2. Turning the screw clockwise
will reduce the oil flow and turning the screw anticlockwise
will increase the oil flow

I was in error your last post is correct! Do you have a bar on the saw?

Yup, bar is on it. I yank the pimp apart and have a look see tonight. Just wondering if there were any parts that wear out and cause the problem. The saw feels like a beast Tim. I put a new piston and rings on it with the jug with the broken top fin.  There was some scoring on that jug. I cleaned it up as good as I can. It's at 130 psi, with no base gasket.

Well it could be that the oil pump is a high volume designed for looking bars. Could also be that it is a crank driven pump, I will check my manuals.

All versions use a clutch driven pump. No oiling at idle. See photo at bottom.

A  little bit of grinding here and there and it pumps less now.

Al, I may have another 394/395 oil pump around here in case you need to get the oil volume up. Especially if you need to run 30 inch or greater bar.
