That’s a REV truck,
You don’t have a TDM or Cadillac valve.
let me tell you what I’ve found on these non-runner trucks after getting them in a few a week for the last couple years…there is absolutely no rhyme or reason as to what or why something was done to a truck in regards to what’s missing.
The one constant is the right rear caliper missing or the line disconnected and no brake fluid for the REARs only is gone, leaving the fronts untouched, I’ve seen this on every model truck…my observations:
Engine oil drained 50% of the time
Tcase drained 75% of the time
Diffs drained 20% of the time
Transmission drained 75% of the time
geared Hubs 5%
just made an M1152 run last night…PS reservoir was removed but present, reinstalled…found it had it a rust hole in the bottom-and immediately started leaking, oil cooler rotted and leaking, radiator shot and leaking, other than that…the truck is like brand new, shows 471 miles on odometer, this truck was stationed on a ship or next to the ocean from the corrosion I’m seeing, folks gotta remember these trucks are on Amphibious ships and pre-positioning ships for years.
