Automite: Be happy that you didn't win this one

Post  rsv1cox on Mon Dec 29, 2014 5:29 pm



When I saw this sellers picture in an ebay ad bells should have went off but they didn't.  Well they did, sorta.  So the flywheel is off  the axle I thought, we can fix anything.  Trouble is, the other half of the engines crank shaft is broken off up inside the axle.  



This thing was a disaster from the beginning.  Instead of the nice smooth plastic finish of my first Automite, this one is crazed like someone wiped it off with a solvent unfriendly to plastic.  The engine was so gummed up that aggressive use of a heat gun was necessary to free it.  I have never seen an engine this bad.  The user must have filled the tank with fuel, then filled the venturi flooding the crankcase housing.  This picture is after I had cleaned most of the gunk out of the housing.

 

When I unscrewed the cylinder the goo inside it held the piston and rotated it off the connecting rod.

The combination of dried fuel and the neoprene residue of the fuel line made a major mess that no detergent or solvent could remove.  It had to be dug out.



Media blasting (aluminum oxide) cleaned everything up.  But it did nothing for the broken crankshaft.  I have a spare engine, but I still have to deal with the axle with the broken half of the crank inside.  I can make one with the proper size steel rod, but it's drilling the hole in the rod that presents alignment problems.  I don't have a lathe, but maybe if I'm careful I could do it with my drill press.  Tapping the hole isn't a problem or cutting threads on the other end for the axle nut, but drilling that hole is.



Any suggestions?

Well, Halleluiah I had two pieces of good luck.  First the threaded end of the broken crankshaft was not inside the axle and I was able to use my Cox piston re-setter tool to put the Wen Mac piston back together.  



The base would not work though as the Wen Mac piston is larger in diameter than the Cox.

I was also able to remove the broken crankshaft from the Automite’s engine and the crankshaft from a parts engine and replace it in the Automite.

But there is a difference.  The size of the Automites crankshaft splined portion is larger than that of the replacement crank.  Probably made more robust to absorb the heavy flywheel.  



Also notice the intake holes are different also between the two crankshafts.



Got it all back together, but I will have to find the crankcase to cylinder gasket before I run it.  Those gaskets are hard to find so I will probably have to make one.





There are differences between the two, one has the pull string start, the other doesn’t.

How did you restore the tyres? Do you know what the white crud was?

I like seeing models brought back to life.

Man, that was quite a challenge. I commend you for your patience to tackle this job.

Thanks, it was an effort, especially those wheels. A two day soak in Simple Green did nothing. It took a detergent, hot water and a stiff brush (a tooth brush would not do it) to remove it.



I have no idea what it was. Wasn't paint, looked like pot ash. I hope it wasn't toxic. Smile

The instructions say to just tighten the drive wheel nut finger tight. The flywheel acts "like a clutch" until the inertia of the flywheel catches up to the engines RPM's.

I still have to take it all down again and bench test the engine before I run it. It's interesting that this one has no provisions for a driver or muffler. I still have to construct a muffler for the other one.

Yes, nice job! Maybe the crazing on the body will polish out? I used a 4" polishing wheel and Novus on the hard plastic on the Prop Rod and it worked very well.

I saw that.  I will have to revisit that thread to see the products that you used and how you did it.  That was a great job.

I used glass top range cleaner and fine steel wool to remove the crazing.  It came out very smooth but dull, but it was dull to begin with.  A little effort with your method should help.

Ha Mark, LOL me, all I need is more ebay competition on these.... Sad

But...here's a good one for you. Looks like a good candidate for restoration.

I still have this one waiting in the wings. Testors Indy Racer. I have a much nicer one but this one has a pull starter on a wheel.





Yes, that's masking tape holding the body together. Twenty bucks and I was the only bidder. Wonder why.

I might not have bought it if I had bought the Automite first. The Testors engine looks every bit as gummed up as the nightmare Automites was, but at least the wheel isn't hanging off.

But, I just like that Automite. Looks...Butch with the 30's/40's styling.

One of the hardest things to find for the Testors Indy car are the stickers.
This seller has repo stickers, they look nice and haven't been around long.
