Questions as I rebuild 144 dexta

hello Dexta'rs,

I purchased a 1959 dexta. Its an oil-aholic. Rebuild kits say "unfinished sleeves". Does this mean I only need to hone? Or do I need to bore and hone? Anyone have a recommended kit? I've seen there are 3 different types of sleeves. What is the best repair manual for this tractor? I plan to do this in-tractor. How do I remove the oil pan in-tractor? I hear dexta's are dry sleeve, yes? And I'll need to dry ice the new sleeve not just freezer it.

I will first put valve cover to verify source of smoking. Maybe its just a head issue.

Update: I found the manual on this site. Very good. Got a few more jobs for "Vector Control" then I'll start tinkering on it.
Yes, dry sleeve.
Seller can answer my sleeve finish question.


thanks

howard

There are two types of replacement sleeve for your engine and both will need to be fitted at a machine shop.

The first is the original type which is press fitted and then bored out to the correct size. This would be the way I would go.

The second type is a "looser" fit and is held in place by a ring around the top of the sleeve. This will possibly be a later 152 sleeve for the Super Dexta/MF35 and will require the block to be modified to take it. You would also need new pistons to fit the sleeve. The sleeve may also require boreing/honing to size.
