Ayuh,..... Welcome Aboard,...... I'm guessin' yer lookin' for a shop manual, for a 4.3l Volvo motor,..??

It's a GM 4.3l long block, that Volvo bolted their accessories onto,....

Hopefully, someone with more resources than me, can decipher the serial number, to help ya find the right manual,....
Do you happen to know it's year, or the year of the boat it's in,..??

There is a serial number engraved on the bloc :126 30 881 and 19 07 15 b0008 (see attached picture )
Do you think it can be a useful information ?
THANKS for your help

HI
Unfortunatally on the volvoshop, the segments are not supplied (see attached )and no delivery time is indicated. Even the local dealer , has no answer , that is why I am searching other equivalent on a similar VOLVO PENTA engine .
are you needing crank shaft parts and related?

thanks do you have the link of the GM parts that could fit my engine ? as a reminder , I am looking for 6 sets of segments
Ayuh,...... Are you callin' segments, what we call connecting rods,..??
The arm with 2 holes that connect the piston, to the crankshaft,..??

Not sure what the numbers are in yer picture, but the Block's serial number is stamped into the block's deck, starboard forward corner, right up close to the cylinder head,....

Do you have a machine shop that builds motors near you,..??
There's more to buildin' motors, than just slappin' parts together,....
If you need 6 connecting rods, that's pretty much a full on rebuild, which should involve machine work, so that everything fits properly,....

I am looking for the piston rings .(see attatched)
of course that the assembly of the piston rings will be made by a professional , my only problem , is that the piston rings are not available on the market .
i will try to find the serial numbers engraved on the pistons

if you need rings, you also need pistons and the block machined first.

because your engine bore is no longer stock diameter and has a taper, because your pistons are now oval shaped and you need to bore and hone for larger diameter pistons.

every engine rebuild shop can order the rings from Mahle, Perfect Circle, Seal Power (both MPR brands) or other piston ring companies. or spend more money on GM rings (which come from Mahle)

So it sounds like you need pistons, rings, bearings, a machine shop and gaskets

the GM part number for the piston ring kit for the 2014+ GM 4.3 is 12663864. $54USD. also available at any GM dealer in europe

HI
my mechanical , said that our engine is in aluminium (with an internal foil coat !!!)he said that they are in good shape , and just the rings need to be replaced .
we will check again with MAHLE , but it seems that they don't have the sizes we need .Unfortunatally GM is not represented in my country , so I will have to check in europe.
thanks a lot
