Hagerty Buick Straight 8 Rebuild - Installing the Sleeves

Kind of an old-timey way of inserting sleeves.

I would have preferred to press the sleeves in my self but obviously these guys know far more than i do. I have been loving following this whole series. With not only the inline eight Buick but also the inline six Chevrolet. Thanks for sharing.

We froze the sleeves using liquid propane (-40 degrees). They dropped in - no force. 3 minutes later, they were set. It was a long time ago but 0.006 interference rings a bell.
Pretty sure Id have been run-off for beating on a cast iron sleeve.

I agree the cylinder liners should have been chilled and they would have gone in easily. Also that sleeve installer would have had a driver that fit into the hole in the middle so the force would act evenly on the sleeve. Wailing it with a hammer and hitting it off centre would certainly increase the risk of breakage.

Did you use Locktite or another adhesive also as per the video ... just curious?

Freezing makes a lot more sense to me. Maybe in conjunction with heating up the block a bit.

You really have to wonder why these guys hammered it in the way they did. They have a shop there that would be able to press them in.

I dont recall using any lock-time or other sealant. I suspect itd get pretty thick at -40F/C and do more harm than good?
I know we had one chance to get the sleeves in. If they jammed or got warm, theyd stick and would have to be reamed out to start again. We wore mitts to prevent warming the sleeves with our hands. Im guessing, but about one in a couple dozen would get stuck & have to be redone.
We did not heat the block. The sleeves were relatively thin with lots of surface area. Theyd warm up too quickly with a room-temperature block never mind heating the block.
I dont recall any coming back with problems, except something about Diesel engine liners that had o-ring seals on the outside of the liner, under a lip near the top?
Brings back memories. Late 70s, I was just a teenager. Thinking of it today, all that propane boiling off had to be just a little risky...

This is want I thought. The Locktite wouldn't adhere properly.
