In the bottom web of the WD45 block where the sleeve orings rest, my block has 2 grooves where the old orings were. Were these grooves machined or has the block corroded and a should try to smooth out the area with Beloza super metal or something similar? There is some pitting in the area but not too terrible. Don't want to have leaky orings.

Those a smooth bores.I know when cleaning mine,the cleaner it got the smoother it got.Lots of sanding,scraping.If everything is down to bare/base metal and you have grooves,I think JB might be in order.

Just talked to a local mechanic shop that has worked on these and he says there is supposed to be 2 grooves cut in the bottom of each web for the orings?? They look like they're supposed to be there, but I never saw one of these blocks close to new.

I am not aware of any WD45 block that has grooves for the orings in the block. Only the D15 block has oring grooves in the block. Check your old sleeves to see if they have grooves in for orings.

Dave I'd start sanding the lower bore holes the 201/226 engines don't have lower O-ring groves so if your engine has groves and it's not just a build-up of crap then I'd do what Mike was talking about he had done to his.

Somebody should set him straight, or find another shop!

Only the D15 has grooves in the block? How about D14 and D10-12?
What is the fix for corroded grooves in D15 block?

The old M&W sleeves had groves in them for the orings. The new sleeves do too.

The block was tank tanked and I cleaned out the lower web with a wirewheel on the end of a die grinder. So there is no gunk in there at all.

DO you think it'd work to fill in with some high quality filler, or better to sleeve. Sleeve sounds better, but also pretty expensive.

Might call your engine shop and get a price to sleeve the lower block before moving forward on the engine, just saying it's a long way back inside again. I'm doing a block replacement on a WD45 gas engine right now over this same thing, if I didn't find a good replacement block I'd sleeve the bottom of the old block and go to work building her.

I think you're right Don. It's a long way back inside...

The rest of the block is good. Line bore is good, and no cracks in the upper web. The deck is a little off though. Just got a price of $800 to cut and sleeve the lower web, and deck and re-counterbore the block. If I was more experienced, I would've caught all this earlier.

Thanks for everyone's help.

That's a little high to me but one thing about it you will have one nice engine after you are done with it. Might look around for a better block. I know it costs money to rebuild old tractors! One good thing about your rebuild is she will not cost what a 45-Diesel costs.
I don't like spending big money on rebuilds but I know who the guy is the customer will call if she go's down. I remember thirty years ago that a engine over haul on WD/WD45 being a straight forward job not the bigger deal it is now.

This is not a difficult repair (for me). I have repaired several engines with BELZONA 1111 (Super Metal).   
Caterpillar even list it as a repair.

What would be the repair process using the BELZONA 1111?
Must it be machined?

Maybe my memory exaggerates problems with time. Back to working on it again last night. There is corrosion on the surface above were the top oring sits, but where it seats and below is fine and smooth. Looks like Coolant corroded down to the oring but couldn't get any farther. So I'm happy.

Lubed up the top and bottom webs and orings with John Deere oring soap and installed the new 4" sleeves last night.

Thanks for all the advice guys. Maybe I'll get to work on another one of these someday and be lucky enough to remember this.
