Cox Engine of The Month
Older Thin Wall TD .049

Older Thin Wall TD .049
I picked this engine up at an estate sale yesterday. It was frozen, and had 50 years of dust and fuel residue on it when I got it. Also, the carburator was washed out and had a split in it. Came home and cleaned it out (not refurbished). It turned out to be a very nice example with excellent compression. Some interesting things I found. It has an unmarked #4 cylinder. The Gold anodizing looks like a rose color similar to the older Golden Bees. The crankshaft was purple in color across the back web and the front. Overall a really nice early model TD. Andy

Andy, does the conrod have a oil hole in the bottom of it? I have 2 very similar to this one. I found them to be terrific runners. Ken

Ken,
Yes, it does. I noticed the hole in the bottom of the conrod when I was putting it back together. I meant to mention that too. I vaguely recall a conversation about it on the forum but didn't remember why it was there. I am guessing this is from the first year the engine came out, only because it is before they started numbering the cylinders. Either that, or they made a mistake, but I am guessing this is an early run engine. The deep purple hue of the crankshaft really caught my eye. Andy

I have an .051 that is identical. Mine has a 5 on the cylinder though.
The purple hue on your crank puzzles me. Are you sure it just didn't get really hot at one time?

Re: Older Thin Wall TD .049
That's likely what happened, as the anodizing is faded. When anodized aluminum gets hot over a period of time the colors can fade. None the less its still a pretty nice early Tee Dee.
I can't remember for sure, but I think the new crank/case number came out in the early seventies?
