 Topic: Installing WD45 engine sleeves question
Posted: 26 Mar 2016 at 9:02pm |
I started installing the sleeves on the WD45 engine this afternoon. I cleaning everything up good with a wire wheel and dropped the sleeves in with no orings. Sleeves turn by hand in the block. Problem is I've got .004 -.009 standout on all the sleeves. Usually in the .005-.006 range. When I spin the sleeves I only get about .001 change on the indicator. I can measure different spots around the sleeves and get from .004-.009 on the same sleeve. Just from the fingernail check I can tell it's different. Block deck isn't perfect but cleans up pretty good. I've cleaned the counter bores with break clean,a wire wheel and scraped with a razor blade. To measure I'm using a dial indicator and magnetic block.
What's my best options? Do I need to get the block decked and re-cut the counter bores? The service manual says to file the sleeves, but that doens't seem like it's help much when I get different readings when checking around the sleeves.

Put the head on and go. The head will push them down. MACK

If you are using one of the good thick metallic head gaskets it should compress and seal just fine on .005 difference, I wouldn't worry

After you run it for a few hrs, retorque the head bolts when COLD and you'll have no issues.

Thanks guys This is my first full rebuild on my own and I want to make sure everything's right.
Would it be worth it to try filing down a couple of the high spots that are .008 after sleeves and O-rings are set in place?

File what?? the sleeves????????? The engine has run 70 years like that hasn't it ?? You'd better be bolting the sleeves in place with heavy flat washers to squeeze them down where they belong before you do any measuring.

I have found that some aftermarket sleeves have a slightly thicker flange, about .002" Have seen it that too much standout on these engines can cause the head gasket to leak coolant on the right side,

Last night I compared the old M&W sleeves to the new reliance sleeves. Kevin's right. The new one's measure .247 flange thickness, but the old ones are only .245. SO that where my .005 standout is coming from.
I had the new sleeves tightened down with 2 bolts and doubled up 1/2 washers, maybe sunk the sleeves .0005. Still around .005 which I'm ok with
The only spot that bothers my is around the thermostat studs I'm getting .007-.008 standout on the 1 and 2 cylinders. Machine shop said it'd be around $300 to deck the block and recut the counter bores. There were some signs of coolant leakage but hoping that having the head surfaced will take care of it. I think I'm taking everyone's advice and giving it a good spray of copper coating and re-torqueing.

I would make sure the corner of the sleeve (red circle below) has a bigger radius, than what is in the corner of the c'bore and the top edge of the sleeve bore (orange angle) has a bigger radius than the inside corner of the sleeve.

Thanks for the suggestion Charlie. I checked last night and neither the counter bore nor sleeve flange has much of a radius. They are pretty square. I took a red sharpie marker and colored the bottom of the flange and spun the sleeve in the block and it looks like I'm getting pretty good sleeve to counter bore contact on all 4 cylinders. I had red ink deposited all the way around the counter bore as long as I pushed down on the sleeve correctly.
Hopefully I'll install the sleeves tonight or tomorrow with O-rings and clamp them down. Thanks for everyone's suggestions.

Keep us posted on how it turns out as this could be an issue for others. I had a antifreeze leak on the outside of a WD45 so I took the head off and cleaned everything up and put a new head gasket on coating it with aluminum paint. Used the tractor for about 10 years after with no leaks.
