engine help please

as most of you know i'm going to fit my spare engine in that's done 55,000 miles. my question is do i fit new bearings and rings in or would it be ok to just use as it is. i don't know how long it's been sat in the shed before i bought it.

i would just fit it and see what its like

ill second that id just fit it should b ok if its genuine mileage and when its fitted you could do a compression test to give you a idea on condition of rings valve ect

you could turn the engine over by the crank pulley nut to check if it's sloppy, or seized. It's hard to explain sloppy, but easy when you compare the feel of 2 of the same.

You'll need a big socket set lol.

Grab hold of the crank pulley, face on, and pull and push it away from you. If you get more than a few mm movement then I'd at least inspect the shells. It'd be a shame to bolt it all back together then lose the bottom end

there is next to no play that i can feel when pulling the pulley.
i'll use it then as it is.
cheers guys for the advice.
