From a previous post viewtopic.php?f=1&t=97865&p=771340#p771340 I think Tim is describing freeze damage. Look at the last picture in the link.

First of all, I would like to thank those who offered us a donar block to work with. THANK YOU!

After considering our options, we have decided to buy a block from JP Tractor Salvage. The block is over bored at 0.04" and comes with a new piston kit, ground valves, lifters and camshaft. All it needs is a crank and rods.

Rocky is the donar and is a match. Any advice or tips on removing and inspecting the crank and rods?

I think there is an overhaul service manual at the "Quick Links" tab. Should give you all the info you need. Good Luck.

Hi,
Below is the Cub service manual GSS-1411. Connecting rod info starts in section 1, page 25. The crankshaft is covered in section 1, pages 47 - 52.
There are 2 sections gone from it. But the engine section is there. There might be another manual like it at the upper left of the page with the missing sections, if you need those. :)

Thank you for the link Glen! Everything you need to know at the click of a mouse.

I was just reminded that the crankshaft pulley has to come off in order to get the crankshaft out. Just about ruined my day.....until I was told that I could remove the rod connectors while properly labeling them, and then remove the front cover. Then, let the machine shop press the pulley off. That sounds about right to me, let the machine shop do the dirty work, yea.

Does anyone foresee problems with this approach?

I would just emphasize to them that the pulley needs good backing so a flange doesn't get broken off. I think you saw how we did it at the Cubfest, which is probably harder than using a press on the crank.

It appears that Rocky's crankshaft has been worked on? Can someone confirm that these numbers represent over sized bearing replacements?

Looks like it to me, measure to be sure though. According to the writing the rods are .030" over and the mains are .020" over making the crankshaft smaller by those same numbers.

:Dito: on Chipmaker's comment on measuring. That's the only way you can know for sure. You might get lucky and find the journals are still in spec after they were turned. Remember the main bearing caps have to stay with the block that they were fitted to and in the same position as when they were bored.

Pulled the crank and got the following numbers using a digital micrometer.

Crank:
Rear - 1.601"
Center - 1.600"
Front - 1.062"

Rods:
Rear - 1.466"
Next - 1.465"
Next - 1.464"
Front - 1.463"

This seems to be in line with the noted "oversize" bearings and original specs.

Did you check each one in several positions to determine if it is "out of round"? Sorry to be a pessimist!

I was not looking forward to removing the crankshaft pulley so much, that I threatened to take it to a machine shop for removal. After debating for several days, I decided to at least attempt it before giving in so easy. It could not have been any easier! :{_}:

Now, does that mean that the pulley needs to be re-sleeved? Or is the clean living paying off, big time?

If there is a wear groove where the seal runs on the pulley, it would need the sleeve. A sleeve will not have any effect on the tightness of the pulley on the crank.
