Heating and rapidly cooling metal in water hardens it.
Heating and allowing it to cool naturally achieves annealing.

Re: Steering knuckle lube
Wheel bearings get the grease, any good grease other than moly.
The Tractra joints in the knuckle live in a big wad of it, too. Normal there.

Re: Steering knuckle lube
That one gets grease via the Zerk in the axle housing bell via gravity. Essentially pump that baby full till it oozes a bit out the felt seals.
The internal shaft seal always leaks a bit of gear oil in there, too. Messy, but it keeps things from wearing out.

Those genset M101's used the G741 gas tank, pretty valuable if in decent shape.

Re: Wheel alignment??
Seeing the same thing on lots of old Dodges, I'd bet your toe is off. Try this simple home test for toe-in: Get one of those 1/2" round coaxial springy curtain rods, wide enough to fit snugly between the inner tread of your front tires. If you 'borrowed' it from your living room, make sure to p...

Re: Wheel alignment??
Camber can't readily be adjusted on a G741. The king pin stubs are welded in at the factory, and never try to bend the housing. A non-issue. Caster only by using an axle wedge either from the front or rear of where it sits under the springs. Higher arch springs will affect camber. Improper caster wi...

Re: Some M37s in Greece by the highway
Greece and Spain, among others, bought a lot of retired G741 trucks from us for military service.
I've seen old fotos of M37's in service in Argentina as well.

Re: replacement bulbs?
If one is using the plastic full round covers (originally fielded on Goats), never fit the larger lamp in the socket that is closer to the lens.
As others have learned, it will melt a hole in the cover.

Re: How to tell if engine is original
Few went thru rebuild programs to include the original engine, as they drew from supply most of the major components such as axles, transmissions, engines, eTc rebuilt previously by Support Units such as Toelle, RR, and other depots. Keep in mind, in the later periods of those truck's use the engine...
