sleeve installation

I just tried to install a sleeve in a 770 block. It went in hard and there seems..... no it does protrude out farther than the others. I'm guessing .002 maybe .003 I will measure with a straight edge tomorrow. I used dawn dish soap as a lubricant and the sleeve did not snap in like the ones in the 1550 rebuild video shows. My question is this normal or will i crack the head?

you need to use something far slicker than dishwashing soap.

Are you working in a heated shop? Put the sleeves in the freezer for a day and if the block is warm, they should shrink enough to drop them right in. Chris

If your gut tells you something isn't right, pull it and confirm you haven't rolled or cut an oring. That's the only way you'll know if anything has happened. It would stink to get it running and find it's dumping antifreeze in the oil.

One of your O-rings may have rolled over on you and not be seated properly or possibley you might have something under the shoulder. Not sure if you would want to pull it again to check, you'll probabley need new O-rings for sure if you do. I think I would try to get it to sit to the same point as the others by using 2 or 4 bolts with big washers in your head bolt holes and cinch it down at the very least. Not easy to put preasure on water side with out head on but you might also first before any thing else want to at least put some water in to see if you have a leak when looking up from under side. That might give you an idea if your O-rings are okay. Is it normal, I don't have enough experience to tell you but when I rebuilt my 1550 I had pretty much the same situation,# 6 last cylinder at back if I remember correctly and I did what I have suggested to you. Still holding about 800 hrs later. Sure there are others out there with lot more know how than me and You'd probabley be wise to wait for their input. Just giving you my 2 cents. I had never rebuilt a motor before that and was worried and ancious about the end product. Hope this helps you. Rocko.

When you get that sleeve out take the orings off and set the sleeve back in the hole. It should NOT hangup and you can turn it in place. If not you need to correct the interfearance. Then, with the sleeve out look at the ramp on the bottom of the block where the orings start to get tight. Look for spots of skale/rust/flakes that will damage and or pinch the oring "too" soon as the sleeve gets close to seating.Chip off and sand/clean. Reinstall the orings dry to the sleeve, then use a icepick to realign the oring , I rotate the icepick 5 or 6 times under the oring . this untwists it. Now soap it up and happy sleeving.

the soap is not the problem, and is perfectly ok to use.

I was always told to never freeze a sleeve if its a wet sleeve. I can see why but have never heard of anyone doing this so who knows if it will hold water. e is right, if youre gut is telling you something is wrong pull it back out. You might possibly have to get new o rings but I think you can get them seperate. While that sleeve is out do exactly as Tom Rowe-Drake says. You may have to clean that area up where the o rings sit in the block. Also make sure you have no crud on the top of the block where the lip of the sleeve sits.
