Timing Chain Lubricating Tube???

[np50dodge]

We were about to install the timing chain cover when we saw a threaded hole without anything in it and another unthreaded hole. After much searching we have determined that the small tube for lubricating the timing chain (shown in the attached picture) had not been installed prior to putting the cam sprocket on. Our question - does this tube just push into the unthreaded hole to be held in place by the screw or does it need to be sealed in some way? Thanks for your help!

Make sure the inside is clean to maximize oil flow.

The tube just pushes into the hole in the block without any other means of sealing it.

This is what it looks like installed.

Only the early series - 48 to 50 - had this oiler tube feature. Later engines used a solid collar-type oil slinger on the crankshaft behind the lower chain gear to sling oil onto the chain - a more positive arrangement, since the early type oiler tube could and did clog up with sludge on engines that were not warmed up each start-up and/or poorly maintained. The front end of the oil galley in the block was just plugged on the later style engines. This was one of several changes between old and new style L6 engines - connecting rod bolt type and cap were a second modification that I know of. There are likely orthers of which I am not aware.

This writer has disassembled two old style engihes, both of which showed clogged oil lube tube orifices. Actually, I drilled mine a few drill sizes oversized before I reinstalled it.

Hope his helps.

Good Luck

Interesting! The pictures I posted are of the original setup on my 1953 Desoto engine.

That oil tube, #600787 is used on most all model trucks (except the big heavy series Moly Blocks) with all 6 cylinder flatheads through at least 1955 and all the 6 cylinder flathead cars as shown in any of my parts books thru 1954. I don't have the later books to show when the change was made-interesting engine design change.

I have a 230 Industrial engine that I was told came from an airport tug at Australia's Sydney airport......it has the tube and I am of the opinion that the engine is from the 1960's.....andyd

Has anyone used the oil slinger on the early style engine? If this will work can you just plug the hole for the tube and use the slinger instead? Can you use the original early style timing chain sprocket with the slinger? I believe there are two styles of timing chains, will only one style timing chain work with the slinger or will any chain and sprocket work? Thanks for any input on this.

somhow I always envision the part in question in one of my Yellow divider Stanley parts boxes and not in my engine. I think I'm in need of some sort of help. Are there any documented cases of Post Tramatic Rebuild, Parts Sorting Disorder?

Wish I'd kept the 1966 Dodge truck factory service manual I had when I had the 63 D200. It had a section on rebuilding the flat head engine which was still used in, I think, a WM model truck. That would have shown a detail like oil slinger versus tube. But I let the manual go with the truck.

Dodgebeforya,

When I overhauled my '48 enegine, I also had on hand another, that was from a '53 truck with fluid drive. My engine had the tube oiler and the later had the slinger. Connecting rod nuts and caps were also different, but otherwiswe the two appeareed to be idenhtical. I do not have the later parts books to compae numbers. You may have better info than I.

Thanks
