Continue Karinya Rebuild, Going back together.

Jeff,

Awesome job on your rebuild. I am in the process of figuring out everything I need to reassemble my A-4. I had a shop do some work on the engine and when I got it back all of the nuts and bolts came back in a bag. I had them all labelled as to where they went when it was dropped off. (I am missing quite a few, but have to figure out what I need ) I have a Moyer Manual which will help greatly. When the machine shop did the work on the crank, they left the pilot bearing in. I tried to turn it with my fingers and it won't budge. Do recall if your new one would spin pretty easy? I would expect it to spin pretty easy, but would like confirmation. I don't want to reassemble and have this go out on me!

Thanks,
Todd

Yes the Bearing itself turns very easy,, but not the outer case of the bearing,, it was almost a press in fitting. and I recall the old one was difficult to get out,,, but I did, replace mine.

As for the nut and bolts. I separated all of mine and label them in plastic coffee cans.
I then sandblasted and wire wheel them to make them look really nice and I separated them by size. Then when i reassembled I just took the size I need. A lot of the bolts I separated by quantity and size.

Another person with excellent taste in paint colors!

Thanks Bill. I remember when you picked your color, that I was going for the same color, As I recall you said yours was more of a Tractor Red,, Mine is Chevy Orange,,, I like the Orange and Black Theme with all the Brass fittings,, Looks Shippy,, and Kind of Has that Harley Edge,, haha.. It Has Been a Long Road but I hope to do a test Start This Week. My Biggest concern, is it seems awfully easy to turn over by hand. But I have been using Assembly Lube,, Maybe it's just well Lubed....

Oil Pressure?

Jeff,
Excellent rebuild. These little engines do rotate very easilly by hand because of their low compression and light "ring drag". There is one thing that I like to do before putting the "fire" to a rebuilt engine which is to crank it over on the starter, with the ignition disconnected, long enough to let the oil pressure build. As I recall, there was another rebuild recently that had an oil pressure "glitch".
Tom
P.S. Sorry Bill.

oil pressure

Looking good!

For sure crank her as Tom suggested to test oil pressure and ease the rings back to life before firing her up.

I think he's remembering my ill fated rebuild, but the oil pressure problem turned out to be okay: a faulty meter.

Good luck!

[thatch]

Nope!

Marty,
Actually it wasn't you're faulty guage that I was referring to, but rather Bill's missing oil galley plug.
Tom

[Marty Levenson]

oops..

I remember that one...! Inspiring perseverance.

The quote of the day in this morning's newspaper was "Absent-mindedness is a form of freedom."

If that is the case, I must be extremely free indeed...

[thatch]

Bill,
You did such an excellent job on your rebuild that many of us were quite puzzled with that oil pressure problem. Being able to go through the trouble shoothing process with you was an eye opener for sure.
Tom

[ILikeRust]

Well once I got that oil pressure thing addressed, there was the minor little issue of the ignition timing being 180 degrees out...

[thatch]

"Great Minds"

Bill,
On a "test bench" A4 that I have named "Rusty" I etched in a beautiful set of timing marks on the flywheel exactly (you guessed it) 180 degrees out. Apparently it is easy to do on these little buggers.
Tom

Say WHAT??

Thatch,

Do you mean 180 out on the crank (flywheel) which translates to 90 out on the cam and distributor? 180 out on the distributor would be a correct timing mark on the flywheel, no? The crank doesn't care if it's on the compression stroke or the exhaust stroke, up is up.

Clarrification

Neil,
The flywheel was positioned using an extension through the center of the rolled pin in the crankshaft. In my case, I accidentally had this "extension" pointing down rather than up.
Tom

[ndutton]

10-4. That was one of the possibilities, the likely one.

Bill's issue was the other one, distributor reinstalled and firing on the exhaust stroke, 180 out on the distributor which translates to a deceptive 360 out on the flywheel.
