I'm getting ready to disassemble my 1987 5.0L Engine. I'm going to measure everything and see what it needs for rebuilding. Any recommendation for a good source for Spec's. I need all the necessary dimensions and tolerances?
:frown:Motors repair manual for one place.
kultulz will have a few hundred pages to cut and paste from.
But the big engine builders here can give you clearance tolerances and the like if you give them a little time, or if you're a little more specific in your questions.
These specs are taken care of by the crank grinder. The only spec you're going to need for the crank is bearing clearances, unless you're doing the re-grind yourself.thanks for the replies.
I could use the following or recommend a source:
Crank Main journal size
Crank Main journal out of round limit
Crank Main Journal taper limit
Crank Rod journal size
Crank Rod journal out of round limit
Crank Rod journal taper limit
you get that info with a bore gauge all by yourself. nobody can tell you the size of your own cylinder hole....Cylinder size
this is a moot issue if you're rebuilding....Cylinder out of round limit
same goes hereCylinder taper limit
now this is just getting silly.... It's Your motor, the piston size will decry the amount that your cylinders get bored out and honed to. it's another question we cannot answer for youPiston size
this all depends on the type of piston you will be using, and the type of piston really depends on the REASON you are building the engine, Race, travel, leisure etc...Piston to cylinder wall clearance
Not much below but the will be of much value until you get your engine back from the machine shop and start assembling it.... Especially the color coded pistons....I was able to find the following on-line:
