I'm having a won't work until it's hot problem with the lift on my 851. Let it run about 45 minutes and it works just fine.
I changed the utf along with hp tranny line and manifold seals(NH) back in the spring and it worked great just as soon as I fired it up. I haven't used it all summer and now she's acting up until it runs a good while.
Fire it up and there isn't much drag on the lift handle like there is no pressure for a few minutes. Then you can feel the drag but no lift. Loosen the pump bleed screw and oil is pushing out. Remove the filler cap and look inside for an oil spray. There isn't one from anything - check again after lift starts working and there still isn't. It has to be a pressure problem but is it a pump or stuck valve? With it not working at all when cold and working fine 45 minutes later I'm stumped. Hopefully one of you guy's have seen this before and can point me in the right direction.
