HELP...liner removal on 1020

I have developed a coolent into oil leak on my 1020 Deere. It is a 1969 mfg with the 135 gas engine, about 1,500 hours on it, runs great. I caught it before any damage was done looks like. I removed the head and there are on obvious problems. Shining a light up into the crankcase, I can see a few bright green drips along 2 on the liner lower edges. Seems that is most likely the problem. The engine serial number is 133647 and that indicates this is the early one seal type liners. Now...how do I get the liners out? I put a piece of wood on the lower edge and rapped it with a hammer but there seemed to be no movement. Any help would be appreciated...I need to geet this thing going soon, we have a small produce farm and it is about time to get things going.

Thanks, Tony
 
I have blocked up to them then used a piece of hard wood block or thick iron on bottom of sleave then used a bottle jack to push them out. Once they get moving doesn't take much to get them free. Good luck.
 
I made this puller for the 1020 diesel that I removed the liners from
The plate is 1/2 inch by 2-1/2 I welded the nuts to keep the puller straight in the liner -I welded the cylinder ring pieces on the opposite side for the 4020 diesel we pulled the liners from
I used a 3/4 threaded rod - 16 inches long and a 1/2 inch thick 8 x 8 plate on top of the block sitting on wooden blocks
used a 1-1/4 wrench and cranked the nut down to pull up the liner
The plate is only slightly longer than the outside diameter of the liner, so the plate doesn't catch on the sealing grooves on the way up -worked great

O.K., got one liner out and will work on this again later this week. Now...this is an older model, engine serial number is 133647T, tractor made in 1969, engine looks to be made in 1968 (date on bearings is 12-67). There is only one o-ring on the liner...which is what I expected...which is what the early ones had. Now for my replacements...I guess I need the "before serial number 162,078"...description states "two grooves on sleeves". I know this is an upgrade, just want to make sure I get the right kit.
