 sprocket carrier, NSN 2520-00-679-7960. The old sprocket carrier will not allow the 3-in mounting bolts to tighten all the way. The added length of the 3-in bolts is needed because of the additional weight and stress of the T150F track.

So check those sprocket carriers before converting to T150F track and replace them with NSN 2520-00-678-8382 if necessary.

After the Conversion

If your vehicle has already been converted to the new track, you may have already noticed a problem. The roadwheel lifter (dog bone), NSN 5120-01-062-5607, that's part of the organizational maintenance That maintenance that is the responsibility of and performed by a using organization on its assigned equipment. Its phases normally consist of inspecting, servicing, lubricating, and adjusting, as well as the replacing of parts, minor assemblies, and subassemblies.  tool set, doesn't does·n't

 work with T150F track. That makes it hard to replace roadwheels.

Order wheel lifter, NSN 5120-01-496-3694, as a replacement for the old dog bone. Until it arrives, mechanics can use the 8-ton hydraulic hand jack, NSN 5120-00-595-8396, to raise the roadwheel arm.

Position the jack on the track below the roadwheel arm. Make sure the jack is centered on the arm spindle spindle: see spinning.

. You might want to use a piece of wood between the jack and roadwheel arm to help center the jack and protect the arm spindle.

Raise the roadwheel arm high enough to keep it from hitting the center guides when removing the roadwheel.
