The could have at least made piston pihn access holes on both ends of
the block !
you have to do the second piston through the first pistons 'area'.
there's a small tool that's an 'examdable grabber' made for extracting
oil pressure relief pistons on air cooled VW engine blocks..........
it's exactly the right size to grab the inside of the wrist pin.
heating the piston helps sometimes too.
But I'm curious what you or others are going to do with your separated
cases and crankshaft.
Are main bearing sets readily availble in standard or oversize ?
I've heard they were hard to get.
I don't know if waterboxers have a thrust issue in the case like
air-cooled vw engines do .......and does anybody line bore cases anymore
anyway ?
Perhaps you'll just leave the main bearings alone- in which case, unless
there is an oil leak at the case split or something .......there's no
reason to take the cases apart that I can think of - except new main
bearings would be better I suppose.
FYI - main bearings on vw engines .......at least traditionally have '3
oversize' things to consider - there's smaller on the inside if the
crank is turned, there's larger on the outside if the case is line
bored, and ..........don't know if wbxr's have this m but they
might..........there is also how wide the main bearing by the flywheel
is...........cases used to get a 'thrust cut' so that the new main
bearing at the flywheel end would fit tightly in the case again..
here's a trick to tell how loose or tight your flywheel main bearing is
in the case. You remove the flywheel, put in a few extra end play
shims, and tighten the flywheel back on.........this locks the crank and
the flywheel end bearing together in one piece..........then you pry
up/down and left/right, and try look for end play ........if the main
bearing is loose in the case ...........you can tell by flywheel
movement. it's not supposed to move there at all.
but have fun !
I will be interested , Very interseted to hear what you find on the main
bearings and what you do there when putting it back together.
My guess is you'll just re-use the exisiting main bearings or put in a
new standard set.
you know about plasti-guage yes ?
it's the rod bearings and rod bearing oil clearance that's the weak
thing on 2.1's I hear.
I'd want the crank turned or polished at least there, connecting rods
checked and rebuilt- new rod bearing bolts, and new rod bearings, and
check the oil cleaarace with plastiguage. Lot of work ! but worth it
to do it right.
( I think I'd convert it to overhead cam and subaru 4 valve heads while
I had the engine this far apart - lol )
have fun.
nice to see you go for it on serious engine work.
