Stuck Cylinder Liners YM1700

[rock2610D]

I used a 1/2" thick piece of plate steel on top of the head bolts, with a 5/8 inch hole to allow althread to go thru plate down to the piece I used to pull liners.

In your situation since you have one short head bolt I would get a plate that is approx the same dimensions at your head and bore 2 holes. Because of the longer span of plate I would use 1 inch there too.

Just so you know I was supprised at how easy the 1/2 inch stock bent. Once I got the "T" in place it did not bend and I was supprised at how EASY the liners came out.

Be advised I had to drill 2ea 5/8" holes in the lower piece, and router out the metal between two to make an oblong hole. This was so I could angle steel on althread bolt as I lowered it thru cylinder and once at bottem I just leveled out the steel and it hooked to bottom of liner.

I have seen mechanics fill the cylinders with dry ice and let stand
for {I think} 30 minutes. The extreme cold caused the sleeve to shrink
and pull right out. Plug the bottom of cylinder with a snug fitting piece
of cardboard. Also filled new sleeve with dry ice before driving into
block. I know it has worked before, because ai witnessed it quite a
few times

Now that sounds like the easiest and cheapest idea yet. I will try that this weekend..

Thanks

On an old 8N Ford, I've seen my uncle put the new sleeves in the freezer for a couple of days before he'd install them. Then take them out of the freezer one at a time and install it. They would go in real easy that way.

Here is another method I have HEARD about. Spray cylinder liners with a fire extiguisher for a few seconds. It rapid cools liners and they pop in and out easily.

I guess you would need a CO2 extinguisher for that but, it sounds like another good idea.

If you have put your new liners in where they hard to put in? I am wondering too about those o-rings. How are they kept in place when you put the liners back in? The freezer idea sound like a good one too.

Called my wife earlier today and she said UPS guy came today; so my new liners just came in. Will install this weekend. New head, pistons, and such also came in

O-rings on old liners are in liners. They fit in a groove kinda like rings for a piston.

Still wondering if I need to paint them like 336 manual states???

I will probably stick them in freezer over nite and use a high temp gasket material on upper lip and o-ring area prior to installation.

I am going to buy some dry ice today and try it tomorrow.

I have the same question as you about painting the liners. The manual that I have (YM195) is pretty close to the YM1700. It says to paint them with a water proof paint too but, I have not painted them yet. I would think that you would need some kind of metal primer and some high temp type of paint.

I too think I will put the liners in the freezer

I have done a lot of pulling in of sleeves and bearings. The freezer will help but dry ice will work a lot better. If you use dry ice be careful as you can freeze burn yourself when messing with dry ice or liquid nitrogen. It would also help to have a block of wood and hammer near as the sleeves can get cocked in hole and lock up. Some times a bump with hammer will make them go right in. If you use dry ice the sleeve should just drop in on its own. Lots of luck. big dan

My sleeves are in Put in freezer over night and this morning I put sealant on them and o-rings. They slid right in. Had a little too much sealant on first one and had to use old liner on top of new liner and hit with a hammer about 5 times and squeezed some sealant out the top and new liner was in place.

Pretty simple really. Chilling liners works great.
