I have the engine out of me 1845 skidsteer and torn down. Machine shop says $85. per hour shop rate to pull cylinder liners. Could be easy or hard. One to two hours. I figure to make or cobble together a puller to remove these liners. Anybody have any suggestions or shortcuts? Thanks in advance.

hi george jd as long as were on the d-188, do the backhoe 188s fit in the 450 crawler.want to find a block to use for either a core or start for a rebuild. looks like mine might of been one of those block patch deals.it works but i could not use it for a core.even if i have to buy a tired backhoe then scrap it for the engine.i guess you have to start with serial numbers? jd how did you make out with that 207 reto fit.

207D was a bolt-in swap. It is exactly the same external dimensions as the 188D and has all the tapped holes in the correct places. The 207D came out of a military forklift and went into my old 580CK hoe. My neighbor put a 580CK backhoe engine into his 450 crawler with no problems. I haven't seen every 188D ever made, but from what I HAVE seen, the differences are bolt-on. An engine with a steel pan has a different rear-main seal retainer than an engine with a cast-iron pan. Also, the oil-pump has to be modified if you're swapping a steel-pan to a cast-iron pan. All it takes is a little grinding on the pump housing. There are many differences with the front-timing covers and water-pump arrangements. Some are pot-metal, some are cast-iron. Some have generator mounts and some have alternator mounts. Some early covers are one-piece which makes cylinder head removal difficult. Case offered update kits for the older engines to convert them to two-piece covers. So, there are many different cover arrangements out there - but all the ones I've worked on shared bolt-patterns, i.e. no problems. Intake manifolds and exhaust manifolds also differ, but again, use the same bolt patterns.

I see other posters have mentioned the sleeves come out easy. That is true sometimes, and sometimes it absolutely is not. All depends on how much corrosion has developed. I've had engines - including Deere, Allis Chalmers, IH, Case, and Detroit, where I could pull the sleeves out by hand. I've had others where a puller was just barely able to move them. I just had a Case 188 apart - block in tractor. I put a hydraulic jack underneath with a bar pushing on the sleeves, one at a time. The entire tractor got lifted in the air and none of the sleeves would budge. I don't classify that as "easy." I finally had to use a threaded-rod type puller, and even with that they came out extremely hard. When all is clean, the sleeves should push in or out by hand, and the only pressure should be from the sleeves fitting into the o-rings.

John, I might have known that you would nitpick the word easy , I guess I should have qualified it.
As compared to most dry liners , wet liners pull
easily .About 25 years ago I had an OTC wet liner puller (1 inch coarse thd) that we pulled a dry liner out of a mack with , it rolled the threads on the lead screw beyond reuse. Since then I got a dry
liner puller ( 1 inch fine thd). Also had a 354
perkins that were very tight, put it in the little
press ( 60 ton ) upside down and thought it was going to break the block , had it not let go when it did I
was going to set the cylinder boring bar up on the
block and bore out the sleeve . I also have a 30
ton hollow ram porta power cyl that I use on the
liner puller when I have to do an inframe , most
of my jobs come in already out of frame .

 What is nit-picking? in reply to george md, 02-23-2006 23:02:31  
Someone that has experience might deem my comments as "nit-picking", but - some of these people posting questions have no experience - thus the questions. I pity the poor guy trying to pull apart a wet-sleeved engine for the first time, after being assured by experienced mechanics on how easy it is, and then being unable to do it - wonders what the h*ll is wrong. I've been in similar situations, it can kinda' makes you feel like a d*man idiot. So, call it nit-picking if you choose. I call it being accurate. On the specific subject of wet-sleeve removal, I've had just as many difficult removals as easy ones, i.e. it is NOT a rare occurrence.

Dave ,

That is a wet liner engine , keep the welder out of it . Those liner come out easy and being that you have the engine out , I would assume that you have the crank out also. Turn the block up side down , set it on 2 short 4x4's , lay a flat plate across the bottom of the liner, drop a large bar on the plate , couple of licks and the liner is out ,do two , move 4x4's to clear the other two . A few minutes and the job is done .

I knew that was a wet sleve, but we all have our methods that work well for each of us. I always grab the welder, just makes the job easier for me, be it a dry or wet sleve. Me personally, I would rather see them fall out than have to beat them out...D..... ...

Pulling the liners is easy, putting them back is the hard part. I cant recall ever using a puller though. Take a welder, weld a bead from top to bottom of sleve, might have to go down each side, ( wide bead, using side to side motion ) sleave should fall out, if it doesn't, a small ammound of persuasion might be needed..... D....
