Fluids needed for M715 series rebuild

[maddawg308]

Okay, time to add fluids to my truck, but the military manuals only list the applicable military standard fluids by NSN and mil type. Doesn't seem to correspond correctly with commercial off the shelf stuff.

Here's what I am guessing for my M715 series truck:

Engine oil: 10W30
Tranny: 90-W gear
Transfer: 90-W gear
Axle diffs, front and rear: 90-W gear
coolant: standard 1:1 ethylene glycol and water
brake fluid: DOT-3

Let me know if I'm right...hate to be wrong.

Thats pretty much what I run in my 725.

Thanks, gimpyrobb. BTW - saw pics and vids of your -725 at Haspin last year. Do you have the stock drivetrain in your ambulance? If so, I'm impressed by the off road capability and power given by the standard drivetrain setup. I was told these rigs were thought to be underpowered for their size, but you'd never know it by seeing your rig at work!

A stock M715 does great in the environment it was designed for. Off road below 45 mph.

The underpowered concerns only show up with those of us trying to use the truck as a modern new 1 ton is used.

You can use straight 30 in the summer in your Tornado.. and GL1 gear oil in the gearboxes and diffs... some M715/25 may have been converted to Dot5, but Dot 3 is what they came with...and regular chassis lube and the 50/50 AF is fine... ACE

Yup, stock for now. Going with a 366 chevy for cheap available parts, 3035a trans for O.D. and a 205 to rid the over heating at speed Tcase. Someday maybe axles.
