ford 2000 hyd pump leak

joe201 · Nov 9, 2012

I have a 1974 ford 2000 3 cylinder gasser and it has a small hyd oil leak at the 1 inch nut on the hyd pump. I have looked in the achrives and at new holland web site and the parts list at new holland it has a protection seal number 45(connb997a) 1/1/65 to 9/30/69.And the achrives at your site says that the hyd line in the 1 inch line is bad. My question is does my tractor have a protection seal or is the hyd line bad. I haven't took it apart yet cause I could live with the leak for now if I had to, but if I could just change the protection seal if it has one. Just don't want to get in over my head and take it apart and put the tractor down . Any thoughts or help would be great
Thanks Joe C

The leak is at the 1/2 line. The nut is a one time use setup. The p/n C7NNH856C, Index# 72A. Depending on how many times nut has been replaced it is a good idea to cut about 1/8in of end of tube if it is crushed about 1/2in from end or deep groove from metal washer in it.

does it have a ferell on it? and how do you get the nut off. I haven't taken it apart yet

Those darned nuts are problematic.
You kind of have to wreck the nut to get it off the tube. New nut is over $40 from the dealer.
When you reassemble it put the nut on first then take a punch and swedge the end of the tube slightly - I mean expand the diameter of the tube just a hair. That should fix your problem.
