bwmuldoon Posted October 24, 2020 Share Posted October 24, 2020 Hey All, I've had an issue with my 1460 combine causing my feederhouse to not want to go down unless I ease pressure onto the steering wheel. If you turn the wheel the wrong way it will cause the feederhouse to raise up. I'm guessing it's bypassing through something that it shouldn't be, but I'm not sure where it would be doing that. A priority valve or something or is it in the valve stack? Not real sure how those two functions are connected. Thanks, Bradley Quote Link to comment Share on other sites More sharing options...

ksfarmdude Posted October 25, 2020 Share Posted October 25, 2020 Mine does the same thing , makes it kinda tricky to put the header on its been that way for years I just never worried about it it must be a check valve problem that causes it to cross over into the header lift cylinders some how maybe someday I'll look into it Quote Link to comment Share on other sites More sharing options...

Iowa5288 Posted October 25, 2020 Share Posted October 25, 2020 There is a service bulletin that addresses that issue. I don't the number but it involves installing a office fitting in the inlet port of the steering hand pump. It helps with steering chatter and the head raising issues.

SDman Posted October 25, 2020 Share Posted October 25, 2020 One of the orifices in the header lift valve was relocated. It was a common problem for years. Not too long after it was fixed, they went to a different valve stack. Quote Link to comment Share on other sites More sharing options...

jass1660 Posted October 25, 2020 Share Posted October 25, 2020 Pretty common for it to want to jump up when no head is on and you steer. Quote Link to comment Share on other sites More sharing options...
