hen the M1074 and M1075 PLS trucks switched over to the new Allison 4500SP
transmission, the vehicle’s speed sensor had to be updated to handle a 24V system.
But when you check out Item 2 in Fig 1 of TM 9-2320-364-14&P in IETM EM 0206 (Apr
09), you’ll notice there isn’t an NSN listed. And PN 1857380U doesn’t cross to an NSN.
Until an NSN is available, order the speed sensor directly from Oshkosh. Call 1-800-392-

aving trouble pulling the manual control (MC) on your M978A4 HEMTT tanker’s
V1 emergency valve, operators? Then get down on your hands and knees and take a
close look at the MC cable’s support bracket.
If the support bracket is bent, it’s likely because the cable isn’t properly adjusted.
As the bracket bends, the cable binds even more. Pretty soon, you’ve got a cable
that’s damaged and an MC that won’t pull at all.
If you Fnd a bent support bracket, tell your mechanic. He’ll replace the bracket,
NSN 5340-01-618-5711, and readjust the cable to prevent future problems.
