Piston and rod removale and installation

[TimF]

Okay so last summer I bought a rebuilt block off a member on here, and I am now barely putting it together (ran out of money last summer). He said it is all stock bore and deck, and he did not get it bored over and decked because it was all in spec, well double checking it today it is, except for a small section were the .002 catches, and will slide though if I put a little force behind it. I know that is the max that can be out of spec. Like I said it does not slide in and out freely, but it catches and I can force it though I guess. I figure I might want to get it milled to be safe.

My question is removing the rods, crank and pistons. I have never before taken apart a block, and I would want to take them out to save money and not have the machine shop do it if I go that rout. Is it as simple as unbolting and pulling everything out, and re bolting it back in when I get the block back, or would there be more to it. Everything is already fully assembled, rings bearings ect, and everything is machined and balanced (6 bolt w/ evo 9 pistons combo). would taking them out for machine work throw something out of spec or is it simple enough to remove and reinstall when it is done.

I will be using a composite HG with copper spray and ARP studs

pay to have the shop do it. you need a ring compressor and a torque wrench.

I have a torque wrench, and the rings are already on the pistons. the block is ready to run other than the deck being slighlty out of spec. I was just wondering if I can just pull the pistons/rods and crank and reinstall is myself.

Yes you can, just keep the main caps and bearings in the proper order, also the rod caps and bearings.

No reason you can not slip the rod/piston out the bore and have the block milled. Then re install the rod/pistons.

** Tech tip**

Measure the piston to deck clearance before you remove the pistons, this way you will be able to tell how much was milled from the block.

so its just a remove and reinstall, simple as that? and what about the rear main gasket? would I be fine reusing it? It was new and has not been ran yet. Thanks BogusSVO you have given me a lot on info.

 

[BogusSVO]

You will need a new front case gasket.

The rear main seal will be just fine.

Now the gasket behind the rear main seal plate will need replaced.

 

[TimF]

I ordered all new gaskets for the other things already, block is torn down, was lot easier than I thought.

The comming apart is the easy part.... putting it back together right is the trick

I would recommend buying a reading a book on basic engine rebuilding. That way you'll familiarize yourself with the parts, terminology, tools, methods and procedures. Read and learn as much as you can from a reliable source before you get yourself into trouble.
