706-d 282 part 2

guys : here are some pic's of the deck and sleeves , serial number 7372 S-Y
let me know what you think on this as I sure its a early one. it was white smoke when it ran. that is what I was told by the person I got it from and this tractor come for north Dakota and low compression.

head gasket is leaking between those two cyl's in second picture. plus first pic. sleeve should be dry. post pic's of pistons also.

Just theorizing here. But either the gasket leaking let oil and fuel down by the sleeve due to compression pushing it there or deck height is off some. Allowing the sleeve to work in the bore a tiny bit. Maybe both. Though if wet sleeves you should see the effect in the radiator with fuel/oil in the coolant.

From your serial # yours is older. (assumes all digits are reported and that that is the engine serial#). If it is it is a wide flange slip fit style. the bottom of the sleeve is exposed to crankcase oil, so oil could get in the space between the sleeves and the native block casting/bore. I think it is too loose. A slip fit is not loose (to my thinking) there is usually only hand pressure needed to push them in, but not fall in the hole. I also think the gasket is blown between 2 cylinders. (it may be the beginning of that event, but it is discolored. Jim

well best way is to mic the bore on all holes and then decide on best course of action . As to going and oversized sleeve and custom fitting such . While out i would have the deck of the block cut and counter bores redone and have the sleeves set accordingly . If everything is not done correctly and that sleeve or sleeves start bouncing around the flange will break off and end up going down around the crank and become pieces and parts . Keep in mind here that your after market parts at times do not come with oversized sleeves unless things have changed since i retired and at times one had to go back to the FRIENDLY Case I H to get and oversized sleeve or the other option was bore the block and press in a repair sleeve and bore to fit. Today with prices the way they are this is no time for shortcuts . If you do not have all the toys to play with then let someone that does and knows what the heck they are doing do the bottom end and the head , then you can do the rest . What they talk about on hand fit is a clean dry block and a clean dry sleeve then a vary light coating of like kerosene applied to the sleeve and a hand PRESS do not use oil . Deck hight is done by micing the flange thickness in four places 90 degrees off then usen a depth mic doing that hole or bore the same way then figure your height and if you need to add shims or not same as fitting the sleeves to the hole ya mic each sleeve and each bore and see what you have then try and fit to the bore mating sleeve to bore and marking what sleeve goes to each hole . same goes for the pistons as they are never dead on .

The flanges on the D-282 liners look very similar to the 504 w/ D-188 that I am working on. Both of these engine #'s 282 / 188 divided by corresponding # of cylinders 6 / 4 = 47 cubic inches per cylinder? So is the 282 the C.I.D. for the 706 and 504 is 188 C.I.D. with just less two cylinders?
