4500 power steering puking

[berky]

My 4500 TLB with remote reservoir and filter will sometime blow fluid out the the vent hole. Usually occurs when cold but not always. I have put a new filter on the unit and changed the fluid but it still happens. Must be something wrong in the pump. Any ideas out there on what the problem might be and is there anything I can do short of pulling the pump?

what fluid you using? 134d spec?

make sure filter is correctly installed on return line, and it HAS the outer cover on it to stop puking in the reservoir. If you see pleats, its the wrong filter..

also check to see if someone shimmed up the safety valve to a higher pressure.

Got the filter at my local Ford construction equipment store and it does have pleats. Don't that just figure. Do you have a part number for the right one? Is the safety valve the large aluminum plug on the side?
thanks for the help

hydraulic fluid that I got at Rural King. Marked as compatable with ford but no numbers.

The correct part number for the filter is C7NN3N538A

better check that!

TSC sells UTF fluids.. but they list specs.. they also list a older fluid marked for use with ford tranny, hyds and diffy, but for fords from 39-52, and it is a 90wt gl1/ gl3 oil.. NOT a utf.. more of a mineral gear oil.

correct filter has a wrap of paper over the pleats and then a metal screen if IRC. No paper wrap and it will puke forever. So its gotta have the wrap... ask me how I know...

on remote reservoir, you can reverse the in and out ports but unlikely as return port is bigger IIRC so it should be obvious if the sizes dont match up. And filter is always on the return port and keeps the fluid from squirting out everywhere.

Been a while.. good luck.

Thanks sotxbill. You know I got on the New Holland site and downloaded a picure of the set up. The lines on mine do not match their pic. The return line from my front steering cylinder goes to the bottom of the reservoir. New Holland shows one of the lines from the pump going to the bottom. Now I don't know if previous owner miss-matched them or the web site drawing could be wrong????
