Ford 4600 Hydrsulic leak

Matt Reinders · Apr 9, 2017

I am finishing up a project and once running I noticed a hydraulic leak at the pressure tube below the flow control valve on the right side of the 1976 Ford 4600 tractor. I'm sure it is a faulty o ring on the pressure tube. Before I remove the hydraulic manifold and perform major surgery here to fix it like the I and t says, are there any pointers or an easier way to get at this pressure tube? I've included two pictures, one of me pointing at the spot of the leak and the other of the tractor for reference. Thanks in advance.

My 6610 is like a dog that has to pee somewhere, and rarely in the same place.

You're not gonna like this...
If it is like a 4000 there should be a circlip around the tube just above your finger - on the underside of the flow control valve. To remove the pump you have to remove that circlip then slide the tube upwards into the flow control valve.
If the leak is on the pump end of the tube, remove the circlip, slide the tube up and renew the oring.
If the leak is on the valve end of that tube - upper end - you will have to slide the tube up, pull the pump, then pull the tube down/out to renew that oring.

Im with Udog but upper orings gonna leak since been disturbed so just as well pull pump and replace both.

Agree.... with one exception. The difference with the 4600 is that you have the filter manifold on the other side... and getting the pump back into the manifold will probably require a rear split or pulling the lift cover.... or both.
