Dana 18 gears and yoke/flanges

Dang I should of came and said hi.  We were just in your town a few weeks ago passing thru.  Had to stop at our favorite fish and chips The Bowpicker.

The teeth.    Mine look like someone never touched the clutch and forced them into gear, chipping big chunks out of the teeth.

Learn something new everyday! I never knew that, so that dates my case as a '52.

Pitting doesn't bother me, if it is not too bad. Obviously I am trying to find the best looking gears but also on a limited budget. ( I know you know what I mean! The 8-18 is better then what I have. ( Mine is missing big chunks on the smaller teeth.)

PM will be written and sent after I post this.

Yes, those are date stamps. December 1951 and September 1951 respectively. Gears with the same part number but different date stamps are totally interchangeable. For example: a gear with the number 18-8-17 1251 would be interchangeable with a gear marked 18-8-17 548. A gear marked 18-8-17 1251 would NOT interchange with one marked 18-8-18 1251.

The part number 18-8-17 meant that it fit a Model 18 gearbox and the 8 meant it was a gear. The 17 referred to the particular gear in an engineering drawing. Each gear with a different design has a different part number and is not interchangeable with gears with different part numbers.

It can be noted that in some instances the gear might say 18-8-28 but be found in some other gearbox, for example, a Model 20. This would have meant that the gear originally had an application in a Model 18 gearbox but was also used in a Model 20. This wouldn't happen very often, but did at times.

Warning: Interesting history follows that does not apply to jeeps:

The Model 24 transfer case was a heavy duty transfer case used in Ford 3/4 ton trucks until 1972 when Ford replaced it with the New Process Gear Model 205 transfer case. The Model 24 had its gears marked 23-8-xx (with xx representing any number used as an example). This was because the Gears were first used in a Model 23 transfer case that was used in some early Chevy and GMC trucks to replace the Napco transfer case and it had a right hand front output to match the front axle on the truck. When Ford specified that they wanted to front output to be on the left, Dana Spicer built a mirror image of the Model 23, called it a Model 24 with almost everything in it identical to the Model 23 except for the housing, bearing end caps, and shift rails. Both the Model 23 and the Model 24 had a SUPER noisy low range because of very large spur gears used on the low range set of gears.

No worries Les. I know you've been busy with your project.

I'm still looking for gears as well.
