I've been told it's possible, but never actually encountered someone who has put pistons back in their B-series from the bottom. Upon looking with everything off and the crank ready to come out, the bore is the same all way down with nothing in the way for a piston ring compressor not to work...So has ANYBODY ever done this succesfully? I'm really trying to avoid taking the damn head off again from the last build!

 

No, I've never seen that done.

 

IMPOSSIBLE!

 

No one ever has.

 

u cant because...u cant...

 

Second this guy...Sorry there is no short cut to doing this. You can't not insert the piston from the bottom up...Also helms don't instruct you to do it that way either...

 

jeezus you have to be kidding right.

 

that has not been possible since the 1930's but if you do take pics. I want to have a good laugh.

 

It was an honest question, no need to flame him. I doubt it has been discussed before.

 

what are you thinking??!?!?!?!?!?!?!

 

there are parts in the way.

I suppose you could sleeve a block and machine it specifically to do this, but it makes no sense to do that.

 

don't do it!

Also there is nothing in the way except for the crank which is coming out...Don't get me wrong I'm not entirely sure it's possible, but why not? The bore is the same all the way down as the skirts of my CTR's come down to the bottom of the cylinder, the oil sqiurters can easily be removed and reinstalled, and a ring compressor (the slip over type) can easily be loosened up and slid over the rod after the top of the piston is in the bore. The only concern I've been made aware of is damaging the rings during insertion, basically going up to insert the pistons instead of down...But once the damn things are installed they go UP and DOWN... so WE SHALL SEE!!! Regardless if I'm unable to do it NO BIG DEAL, then everybody will know NOT to waste their time, but if it is possible then I'm sure there are a few people out there that would love to save some dough on a new head gasket plus a few extra hours of work........

Uhm, sorry to burst your bubble, there is a stepped edge on the bottom of the cylinders on all b series blocks. Pistons cannot come out or go in that way unless you machine that piece out or the piston is in mulitiple pieces.

I suppose mine DOESN'T have a stepped edge because of the overbore I have, if anyone has a picture of this edge I'd like to see it, as I cannot remember what the bottom of my cylinders looked like when they were still stock...As soon as I get the crank out I'll take some pics, as I'm guessing the machine shop nixed the stepped edge you are talking about......

You could probably take care of that with a good ridge reamer, my question would be how you'd keep the piston rings compressed all the way to the bore. I admit I haven't pulled the bottom end of a Honda motor recently, but I can't imagine the mains not getting in the way.

 

The step is over a 1/2" wide. So it would take more than a ridge reamer. Also, it would be very difficult to compress the rings and not have them pop out if you could do it that way. Just save the time and effort and pull the head.

 

you've got to be kidding.....YOU CAN NOT PUT A WORKING PISTON INTO A BSERIES BLOCK from the bottom!!!!!!!!!!!!!!!!!!!!

I GUARENTEE IT!!!

i have had over 200 blocks apart....HEAD MUST COME OFF....as azsi22 said there is a step down there.....and NO you can't ream it out!!!! duh....

to not listening to what other who have experience have said!

 

what about after market sleeves

just curiuos...

 

Didn't I say I haven't had a B series apart? However, a good ridge reamer can take care of a whole lot if you've the will to use it I agree though, the head should come off.... prolly a lot easier in the short run.

even with aftermarket sleeves is can not be done....

if you are wanting to put them in from the bottom still.....the crank must come out....and to get the crank out the tranny must come off.....and the flywheel and clutch....


SO YES IT IS IMPOSSIBLE TO PUT PISTONS IN A B SERIES FROM THE BOTTOME WHILE IN THE CAR&gt;&gt;&gt;&gt;&gt;&gt;......


goollllyyy.....and no a ridge reamer would not help....do you not under stand how much material you'd have to remove....thus causing structural degrading of the integrity of the block!!!!!

holy crap....i can't believe how many people go around their *** to get to their elbow!!

 

This is BrewerHatch's GSR block. Look closely, if you bore the cylinders all the way down you remove crank journal material. If you go with a larger bore then you would end up removing more main bearing material. I suppose that it could be done but why? you would have to take the engine apart either way. Your choice.

No, I don't... I believe I've mentioned that.... twice.
