I had this problem before, two things to do # 1 plug bottom of cylinder, put dry ice in it or use puller bushing and 5 / 8 s all threads big iron cross engine bottom
Bill, ring gap is critical to proper compression and preventing catastrophic failure from heat expansion. If the gap is too close, the ends of the ring could touch one another as heat is generated causing ring bind and eventually damaging the ring groove and separating the top of the piston from the skirt. The manufacture of the pistons should have provided the min/max specs for ring gap. Otherwise, you've assembled a grenade waiting for detonation. I know it's a lot of work, but pull the pistons back out and gap the rings properly and use assembly lube on the rod bearings and oil the rings with regular motor oil.
wow, I am very happy you did well with the sleeves and pistons / rings. Congrats, now just get that last set of rings installed and piston and you will be home free!! Thanks again, I enjoy your videos.
I broke two sleeves on my 8N, ordered two more and took the block to a machine shop and they successfully installed them. I tried the freezer trick and it did no good. The sleeves were made in India and the two that broke just kinda crumbled apart at the top. I used the “hockey puck” puller to drive them in but I did not lube the bores either.
I am about to install new sleeves in my 800 series with the 172 engine, I have been planning on letting the new sleeves sit in dry ice before I install them, I just don't want to have to beat them in like that, I do hope everything turned out alright though, thanks for the video
Bill a freezer isn't cold enough to install sleeves unless you can get it in in about 1min.. Best is Liquid Nitrogen, if not then dry ice, put the sleeves in a box and completely cover the sleeves with the ice for about 30mins and only remove the sleeves from the box when you are ready to install it. They should then just slide straight in with maybe a little knock, you should never have to belt the living shit out of them to fit
I know you got them in .but a chain and head bolts and a bottle jack and your little puller plate hydronic to press them in!! Love the vedio. Did you notice the dent on the block metal on the second sleeve you put in ?
I have been following your channel for many years. For some reason I got unsubscribed from your channel and it really made me mad. Not sure how it happened but glad I am back. I missed so much! Keep up the good videos.
Not sure how similar liquid nitrogen is to liquid oxygen, but the latter requires some safety considerations. I like my bill the way he is thanks. No poof, no broken off frosty bits,

I respectively agree with this..
I would think they factory set the gaps for the rings as they ere installed in the cylinders

For me a freezer was plenty cold enough but we did also slightly heat up the block
Thanks Bill...

47:42 I would take the die grinder to the top edge so the sleeve fits easier. Hope you used assembly lube on the rod bearings.
yes they were lubed up
Hopefully they will replace the broken ones.
I believe that cylinder was oval and was sleeved to make it round that's why it was thicker on one side then the other.
Good job, thanks for sharing the video !
I am wondering if you can trim the bottom of the sleeve to make it go down that little bit so it sits flush
Looking good!
Leave sleeves in cooler or fridge until assembly
as we did
Hey bill were did u get that box of sand paper at that's pretty nice made in strips that way

Sorry to hear that
It did that to me too. i think because i haven't been watching for awhile and youtube auto unsubs you.
Hi Bill, shave the top of the sleeve with a file or something
Hey Bill next time run amd get some liquid nitrogen lol. It's cheaper then you think. And tank rental
But overall makes the whole job a breeze

Liquid nitrogen or dry ice.

Dude you need a bigger hammer
WTF ARE YOU DOING ??? Holly Crappers . YOU NEVER DRIVE ON A PISTON SLEEVES. DISTORTION WILL RESULT ! 😲😳🤨
well on the plus side, this vid.should go viral on the worlds worse botched engine rebuild on u tube. 🤣
How do you figure that?
