Do all diesel engines have sleeves in the cylinders? I got to wondering if one of the many items to be changed when rebuilding a diesel engine was changing the sleeves and piston rings and dropping the crank. What all else is involved when doing a complete rebuild? 8)

 

I would also like to know what all is involved in doing a complete rebuild as well?

 

Depends on what engine you're talking about; if it's in a class 8 truck, YES it has sleeves, and yes they are replaced during an overhaul. The crankshaft is usually NOT removed during an overhaul... unless a condition warrants its remnoval... the crankshaft main/thrust bearings are replaced during overhaul.

A ford powerstroke (IH t444e) or GM (isuzu) duramax does not have sleeves.

A cummins ISC has sleeves but, an ISB does not.

A 4.2L GM inline 6 gasser also has sleeves because it has an aluminum block (dry sleeves).

Small Deutz air-cooled diesels have sleeves as well.

A detroit 2-stroke has sleeves --- some are wet, some are dry.

 

A complete rebuild generally includes;

fitting rod and main bearings

fitting cylinder kits (pistons, pins, rings, and liners (sleeves))

replace cylinder head(s)

bottom and top end gasket set

additionally; oil cooler, fuel injectors, engine brakes overhauled

some (certainly not all) dyno it to measure hp/performance

Anything over and above that is typically the result of problems found with components/systems during the overhaul.

 

I don't think the older volvo engines had sleeves.

 

I rebuilt an I-6 out of an '88 Volvo L90 this past summer... it had wet sleeves.

 

I heard (truck stop rumor) that the mid 90's or so volvo engines didn't have sleeves.

Not the most reliable source!

 

You could well be right, allan. I checked quickly on tractor-trailer.net and they don't mention anything about sleeves or liners in a '95 d12. Maybe that's part of the reason for their lack of popularity... if you scratch a cylinder wall... well, it's part of the cylinder block (that's no fun!). Speaking of lack of serviceability, I was talking with a FL tech yesterday who tells me that if liner protrusion is low in an MBE, the block is scrap... the counterbore ledge can't be cut.
