I recently purchased a six Hyd control for my ford 861. Does anyone know of a place to get new ones?

Thanks
Mike

Which Orings?
The ones to install it on the tractor or
the internal ones?
You can buy the oring kit to mount it for
not much $ at the dealer.
 

About all you need to know is the width and I.D. of the O-ring to get replacements. Measure the grove withe and the I.D. of the grove. This site will list a bunch of specs for standard and metric its confusing throw out every spec and use the Width and I.D.

The width could also be called the C.S.

About all the o-rings you will need for a Ford tractor

-114 (14457281)
-117
-212 (86553262
-214 (86629540 are CONNB997A)
-215 (CONNB998A)
-216 (134372)

The o-ring should fit the grove somewhat snug with no distorsion to the o-ring and not protrude more than .040
I like .030 to .40 YMMV

As a general rule
Less than .015 wrong o-ring move up in CS
More than .040 wrong o-ring Move down in CS

The ID is set in stone YMMV
