The axle tubes hold quite a bit of oil that doesn't get drained with the rest of the oil, therefore I added the drain holes.

The later Cubs did use needle bearings and all the info I can find says that they used the same axles so they must be hard enough. They constantly run in oil at low speeds so I think they'll be ok. If I knew what kind of steel the axles are made of, I would flame harden the area where the bearing rides.

I got one of the axle tubes bored out today and ordered new axle seals.

Picked up my engine rebuild kit today so I can now get the cylinder bored.

Nice work, I always do the drain holes on the aluminum rears when I have them apart. :beerchug:

.0005" is the max out of round. I'd grind that crank. If not, you'll wish you did in a few years. Not likely right away..... but in a few years.



Looking good Adam!! :beerchug:

Looking good... I hold a special place in my heart for a 100... Learned to drive Dads when I was 4 years old circa 1975. wish we still had it! Keep the pictures coming!

Checked the cylinder head and found it was warped .010" so I milled .030" off to flatten it and bump up the compression a little.

Got the engine tins stripped.

Pressed in the axle bearings and new seals. Found a Stens seal that fits perfect. Has the spring on the back side just like the factory seals.

Had some gasket material so I made axle tube and rear cover gaskets. Need more material so I can make a shifter gasket.

Got a chuckle when I opened the box of the new piston and found this.

Bill's Motor World? :biggrin2:

Adam you're coming right a long. I like your work as usual. Question, are you sure those ridges will clean out with just a .010" over job and piston?

The bore checks .003 over at the biggest spot. It will be fine.

Started putting the rearend back together. Scraped some loose paint.
