D13000 Liner Pulling Tool

I just made one from a piece of shaft. Mine was for a 4.5” bore but the same concept. Basically, you will have 2 diameters on the puck, one about .010 less than the bore that will fit inside the cylinder and the larger part usually about a 3/8-1/2” larger than the bore that will fit underneath the liner and post it out. It essentially looks like a dime stacked on a nickel. I have a 3/4” fine thread in the center of the puck and use ready rod with a nut welded to it on one end to pull the liner out. You also need a “bridge” to go over the liner that the ready rod will go through so as you tighten the ready rod, it will pull the liner. You only need a few inches to bust the liner loose, I have seen people make the bridge as long as the liner or longer. You don’t need that, just enough to get the seals out at most.

I can take a picture tomorrow if you need me to.

You can make the puck round, or round with two side flattened if you want to fish it in or out from the top. I am going to make a round one for use with dry ice in the bore, admittedly the bridge I threw together is a little wimpy, so a more substantial bridge would probably pull the very stuck liner I am looking at.

I was thinking of making a round puck for the bottom, but thinking about a 6" or so piece of heavy wall pipe at the top. Then take a 1" or so thick bar and go on top of the pipe (acting as a bridge). If the top bar was chucked up, I could cut a groove in the flat top bar so that it sets on the pipe above and keep the pulling threads centered.

Going to the steel warehouse to see what I can dig up today.

How far do I need to pull these liners up before they will come loose?

A lot of times, once they pop they will lift out. Sometimes you have to crank on it until the seals lift out. Just depends on how far the seals are down on the liner. Usually not more than a few inches. I think my bridge has about 3 inches of clearance on it.

Here is the one I made for 4 1/2 inch liners in a D-6. The disc just needs to be bigger to fit your liners. BBOAZ[attachment=55274]20190724_090150.jpg[/attachment]

Thanks for the comments guys.

I thought I was gonna come up short on the pipe I needed, but there is a standard DOM pipe size which is 6 1/2 ID and 7 1/4 OD. That should work perfect for pulling, so I bought a 6" chunk.

Got 7/8" plate for the bottom, but must have been 4140 or some grader blade stock because my 9" South Bend groaned and HSS melted like butter on it. I had a few carbide tools and got it almost done- just need to bore the hole in the center. 7/8" Grade 8 ready rod coming from Mac Car tomorrow and hopefully can pull a sleeve on Saturday.
