Replacing Meyer Plow Power Angle Ram Packing Set


THE most important thing is to get the Packing Nut loose. IF you cannot get it loose, there is no point in buying a new Packing Set. If the chrome on the rod is rusted, chipped, or pitted, there is no point in replacing the packing set. Getting the nut loose is either very easy, or impossible, in my experience. The nuts are usually cast steel, and shatter easily.

THIS is what I have found to be the best way to hold the PA Ram securely to work on getting the nut loose.

Loosen the Packing Nut all the way, and then yank out the Packing Set and Rod. I got this one loose and took the PA Ram apart a few months ago, so it is dusty.

I separated the Packing Set to show the pieces. Take a picture of yours before you take the old ones off so you have a record of how many, and what order they are in. The new Packing Set will be installed the same as the old Packing Set.

The new Packing Set comes with a new Wiper for the Packing Nut (sometimes called a Gland Nut) as well.

Getting the old Wiper out and installing the new one can be a task. There is a special tool for installing them, and no, I do not have one.

You can see in the picture that I do not have the Wiper fully seated on the one side. It has to be fully seated.

New Packing Set installed on the Rod, you can see that I have two leftover pieces, which is fine. Packing Sets are for more than one PA Ram, you just use what you need from the set.

The Packing Nut must be installed from the end of the Rod, so it is important to remove all the rust and paint. You will have a VERY hard time trying to put it on from the other end.

Some Rods have a numerical code, and others just have a date stamped on the end. You can also see the end of the rod has a taper to make getting the Packing Nut on easier.

If you ever want to get the Packing Nut off again, use anti-seize on the threads.

Coat the Rod and the Packing Set with hydraulic oil to make assembly easier. I am holding the split washer in place for the pic. To hold the split washer in place for assembly, use a dab of grease on each half to hold it in place while you carefully get it back into the tube. Be gentle, wiggle it a little and it will go in.

Work the Packing Set into the threaded part (that you coated in Hydraulic Oil as well) and then use a blunt drift to gently work the packing into the tube. Work your way around with gentle taps. You need to get it in far enough to use the Packing Nut to push it into place as you snug the Packing Nut.

A little blurry, but you can see I got the Packing Set in about 3/8" which is enough to use the Packing Nut to seat the Packing Set.

As you tighten the Packing Nut. make sure you can spin the chrome Rod, and move it in and out, not necessarily easily, but that you can move it. If you over tighten the Packing Nut, you will lock the Rod in place. You generally snug the nut, then test the Ram. IF the packing leaks, snug the nut a little, and repeat until the leak stops.

It so happens that the nut was tightened down completely. Often the Chrome Rod gets tight before the nut if fully tightened. That is fine. The nut does not have to be fully seated. Take note of where the nut is with your old Packing Set, and you will see what I mean. That's it!
