I can imagine some frustration when working in such confined spaces, oil all over the place. But the satisfaction when you'll be digging with this backhoe will be something else! :cheers: oh how much I would like a backhoe like that. One day..

Some have ask why posting has been on hold. The last week has been spent taking out carpet and intalling floating flooring and other home renovations.

I can see now why the quote for doing the stair way was $100 per tread. Undercutting the pieced tiles has been a learning curve.

A box of tractor parts arrived this week so motivation for completting the floor is high.

Finally found some time to get back at the restoration. Spent the afternoon puting crank, cam, valves, and pistons in. All new bearings, valves and guides, pistons and high end rings. Hope to finish by the end of week.

The engine assembly was going well until the new armature would not fit. It took a bit of time for the cause to become apparent.

When removing the flywheel, it was found that the armature was missing. Now the reason is obvious. Two of the standoff lugs are missing and 1 of the mounting bolts is sheared off in the cover.

At least there is a spare cover here but it needs a lot of cleaning.

I am looking for a timing gear cover. :violin: The cover that came with and engine of unknown origin has the same casting number but :headbash: The difference between the two is the Case cover has bearings top and bottom for the governor shaft to float in, the cover from my stock has a bushing on top and aluminium on steel at the bottom of the shaft with no provision for bearings. With the cost and time put into this rebuild cutting corners by installing a cover with a loose fitting governor shaft is out of the question.

I will add pictures of the differences later.

Oh no! Bummer! :cuss:

It'd be nice if you could put a bronze bushing on the aluminum side. :geek:

Your stator got wiped out by either the flywheel magnets coming off or the flywheel itself. There have been many flywheels cracked from over-torquing the bolt.

I have also seen where an owner hacked a hole in the shroud to change a starter. The debris from the hack job was picked up by the magnets which both shorted the stator and took out the stator. The hacked hole will always haunt the engine in a loss of cooling air that escapes from the hole in the shroud.

Short cuts are often a fool's folly.

Thanks for all of the feedback. A member here came through with the timing gear cover and bonus engine tin for the CCKA.

It is awsome having a fellow enthusiast close by.
