Hi guys here again

the past weekend with a friend we remove the engine from my Aspen... was very hard because i forgive remove the 4 bolts of the torque converter.. but finally we did it...

here put some photos of the engine and the Aspen the man in red shirt is me...

http://www.facebook.com/media/set/?set= ... 0b8&type=1

well... tuesday i disarm the engine and when i remove the 6 pistons have a code on top "TRW L3012F 020" is this code the size of the piston? if this code is the size... is the standard or oversize?



and the connecting rod have two pieces like a C in the crankshaft connection...(i don´t know the name in english) 11 of them have a code in one side "8 89 CB1214AL A" and just one of them have this code"8 89 CB1214AL B A"... i don´t know what means that... well my question is if this "things" are standard or oversize...

well... tomorrow i´ll take some pictures ´cause the camshaft have some older rust... and i don´t know if i have to replace it or reinstall the same... and the same thing with the pistons well... thans guys read you tomorrow...

Bet you don't forget the 4 torque convertor bolts again. This might help you find out what the numbers on several parts of your motor-

If you scrape off the carbon on the top of the piston, the manufacture normally stamps the oversize (.020 ~ .0?0 ) ? is any other oversize.

That TRW L3012F is the TRW piston part number and .020 is the overbore size...

On the other items, its time to get out the micrometers and 500 grit to shine up the crank and measure the journals...

yes the size is 020... but i don´t know if is the standard or the engine was modified... before me

Someone already bored the motor .020 oversize.

The C shaped part is called the rod cap. Keep the caps with their respective rods. They should be stamped with a number, 1-6. Hopefully you already know this and are keeping them together.

CB1214AL- BEARING ROD 1976-87 S6 CAST CRANK

Measure the rod journals and determine what you need. Only a micrometer will help at this point. Once you have good measurements, compare that to the bearing sizes that would be needed to maintain clearance specifications. If the meaurements don't meet specs, machine work will be needed.

The pistons are aftermarket, not OEM. (Pretty good ones too.)

hey CJ obviusly i keep all rod caps in his place just remove to see the code...

the make of rod caps is clevite 77... is this a good make?...

a friend tell me that buy a micrometer but he said something like external... i don´t know how to get it?... well in the afternoon will take some pictures of the camshaft cause it have some rust to gimme some oppinion if is really necesaire to buy another...

what of these i must buy to measure (upper to lower)... number 1...2...or 3?

Not sure how much micrometers cost where you are. A cheap one will run about $40 here. (Chinese) The one pictured at top would be what your looking for. A good one will appoach $200 real quick. I have European and US made ones in inch sizes. The European ones are a bit less expensive than the US made ones, but seem to be fine.

Another option is simply to have them measured at a machine shop that already has these tools. It also gives you the peace of mind of having somebody read the tool that is accustomed to the scale. Micrometer scales are not always intuitive, and it is critically important to measure correctly.

Clevite brand is fine. The number you gave is a Clevite part number.

I have no useful advice. But I love that you and your friend are removing an engine on the side of the street I could never even think of getting away with that around here.

Small bit of information... The thin C shaped pieces, with the numbers stamped on them, are the bearings, not the rod caps. They are consumable, meaning they are the part that is designed to wear, so the connecting rods or crankshaft do not. I hope this helps.

you are saying that the thin pieces are bearings... nice
but how can i know the size... or i must carry the piece to the shop and they sell me a right bearing...
the connecting rod is the piece that pull the piston from the crankshaft?... sorry but i don´t know the names of some pieces from the engine.. specially this litlle things...XD

The connecting rod is the part that connects the piston to the crankshaft.

From the information you have posted, your pistons are .020in oversized from original, and the crankshaft is still the original size unless there are other numbers stamped in the bearings. They would be something like .010 or .020 and at the end of the part number stamp or just under the part number stamp.

The best way to know for sure is to have the crankshaft journals measured at a machine shop if you do not have a micrometer or calipers to do it yourself.

To get the proper size bearings, you will need to take the crankshaft to the machine shop. They will check to see that it is in good shape or will need to be resurfaced to the next undersize. Then you will know what size bearings to purchase. One thing to watch is the main bearings have a hole that must be aligned to the hole in the block or you will not get oil to the rod bearings.

hi:

saturday gone to the machine shop... and the guy tell me that i have to meassure before to buy the pieces...then tomorrow i will go with the crankshaft and the block, to meassure the crankshaft and resurface the block.
and the guy have a used camshaft... without rust... i´m so happy about this... because i buy it for a CL$20.000 like U$40.

tomorrow will take some pictures and i´ll up.
