wbx eng tear dn?

[morymob]

Tearing dn a wbx eng that is locked solid, probably a spun brng, seems to be a real chore.Pull all liners & 'maybe'get to some rod bolts? Cant see splitting case as far as it will go will help if crank held up by a frozen rod or am I overthinking this?? Done with type 1s ok. Anyone care to comment that has done this?? Have. a 1.9 I want to tear dn. 4 possible salvage, thanks.

I think once you have the heads off and the cylinders slid off, you'll have a better idea of what you are up against. In theory, a rod bearing should seize well ahead of the a main bearing. It is a little difficult to remove the pistons from the rods installed, but if you can, you can split the case with the rods attached to the crankshaft.

My thinking is a frozen rod wont allow u to turn crank to get to rod bolts even if liners r pulled neither can u remove piston pins, will try this later, I do have a sawzall if needed.

splitting the case sounds easiest - can't you pull the pistons through the block? i never tried, but given how the sleeve fits into the block, i think it should work. certainly kinder than the sawzall.

after you remove the heads, you can remove the 4 water jacket nuts that hold the case together. i had to use a breaker bar on one of those. the rest of the case nuts were easy.

other question is whether it is good practice to just do the whole thing as you have a lot of work in it already

Thought a bit at times today, if pistons r past top & bottom stroke no pins r coming out. With liners out , if its a rod should be easy which one, the one thst piston dont flop up/dn. Was a quiet good running eng, 1.9, had started it up a few times, last time it idled 4 a couplemin, sputtered & stopped. Tried to restsrt & only a starter click, put a bar on pully nut, no budge either way. Cant remember if u can down the side of pistons to any rod bolts.i also have a good selection of hammers. Might be a worn off oil pump drive or cam slot, never seen one.

Yeah, I was not thinking... Of course you can pull the sleeves over the pistons once you get the heads off. Then you have easy access to the rod bolts.

ONLY if u can turn the crank, that is the main problem, locked up tight.
