660 piston pump leaking. A lot
Finally got around to this. Pulled pump, removed end cap and replaced gaskets. Had to remove the other end of housing to reassemble as piston springs protruding prevent reinstallation of the end cap. No big deal and immediately obvious the gap between end cap and pump housing was smaller... -

UD - could you offer a little more clarity in your reply re:pressure test? If it is too high and you send me to the pump, based upon other replies, Id just head there now. Wont happen today though. Gotta go spew a couple more gallons of hydraulic fluid around the farm mowing buffers. -

I dont think I have a crack. Have you got torque values you like for the 7/16-14-20 studs? -

I think you may be right. If the pump cover is leaking where it joins the body it would be very difficult to see until it got to where I can see it. -

Thanks, I actually did the pressure test which led to the pump rebuild. Top cover can stay on and accessory plate gets flipped around over a self-made paper gasket to block pressure tubes. -

660 piston pump leaking. A lot
This had occurred to me so I got it cleaned up quite well last time I pulled it off to look for cracks and watched it carefully on startup. The fluid appears to originate from the rear edge where the pump cover joins the manifold. It gets increasingly difficult to see as that edge disappears... -

660 piston pump leaking. A lot
I rebuilt the pump on this tractor a few months ago after losing lift. Got my lift back and its fast, maybe too fast? Had lots of planting work to do and got it done but maybe didnt notice there was leaking happening until I found low fluid level. Filled it up and started paying attention and... -

For archive purposes, while symptoms matched my 660, running as long as using choke, for which new points were the cure, not so for this 8N. New points and set timing, ran great...fully choked. Cleaned and put in a carb kit and purring like a kitten.- Billybuck

Thanks Bruce. Ill change the points but they dont have many hours and got a new resistor on the last change. Why would the richer mixture help with the weak spark condition?- Billybuck

Ran my 660 over 50 acres of ground in the last month with no issues until the last day or two. Noticed a change in sound maybe fuel or maybe electrical. Required more choke to start last couple days. Ran a crisp bill through the points and seemed to improve for a half hour then went downhill and...- Billybuck

Piston pump
Thanks. The pump went on fine and I have my lift back. Its strong and fast. Curiously, if I stand on the lift with no implement, I get rapid vibration while lifting which I think it was Dean who said that might indicate sticking piston(s) but it snatches my heavy Ford bush hog no hesitation. I... -
