A new warning label so I don't over shoot anyone by a week and a half ;)😁 My truck wouldn't look good in plaid.

What he said! 👆;) Thanks for the shout-out, Brother Brutacus! 👍👍

WOOHOO! I finally made the Big Time! Thanks to all who supported the Hannibal 8 and Crew!

Yes, you can. The mainshaft and countershaft are common to both. However, The drive gear ratio is different between the two. So, I did the math and just replacing the third gears widens the hole between 2nd and 3rd to around 78%.

Thanks for your reply. The sale I have my eye on said the tranny came from a 1979 International S1900. In what capacity (bobtail box, dumptruck, tractor), its not stated. We have several decent grades out here and I've had to take them all in 4th high, one in third. So, I should be OK there...

I have mulled over the alternatives for replacement transmissions, i.e. 6, 7, 8, 9 or even 10 speed, for my M818, but have run into issues including over length, over width and PTO incompatibility. Some of these problem may be cured, but only after major modification to the drive train. So, I...

Ah, heck! I haven't played in a while. @USAFSS-ColdWarrior, is this the proverbial gauntlet answer? ;)

I converted an M809-series truck to straight air brakes ridding myself of the questionable air-hydraulic brakes. M809-series (M818) Air Brake Retrofit

Correct. Going to outboard drums was a project in and of itself.

The M39/M809-series and M939/M939A1-series hubs are dissimilar. The latter are narrower on the spindle housing.

I did it on an M818 with drums, hubs, spiders, and shoes from an M931A1. https://www.steelsoldiers.com/threads/m809-series-m818-air-brake-retrofit.140055/page-3 Start with post #55.

Thank you! 👍

My M818 next to my Dad's '30 Model A

This is the seal part number straight out of the -34P, 11669023.

I just finished my second replacement of the oil seal on my M818's front axle's front companion flange. However, I am still getting a leak during longer trips when the axle warms up and gear oil flows easier. The leak originates behind the companion flange deflector, obviously from the seal...

You would have to go up to 16.5 x 7 s-cams. All the M939-series trucks are 15" diameter. Seeing how the the same spider for the wedge brakes is used across all incarnations of the M939-series and the M809 and the M939A1/A2 axles are the same, then the spiders, s-cam brackets, s-cams and chambers...

I found this Boeing document. It goes into detail on how the truck was operated with some "propeller head" info too. It was not a launching vehicle. It provided transportation and emplacement into launching structures.
