Maintainers, if you've done a visual inspection of your HEMTTA4 truck and discovered hull, cab or foot well cracks, don't panic! These cracks are cosmetic only and don't affect the safety or function of the truck.
Example of hull crack
If you find the cosmetic cracks unsightly, a cover plate is available in the supply system. The cover plates along with sealant will help prevent water intrusion into the cab.
You can order a HEMTTA4 cover plate kit with NSN 2510-01-692-5253. When it arrives, cover the cracks with the cover plates and attach the plates with the hardware that already exists on the trucks.
You’ll also need desert tan sealant compound, NSN 6850-01-586-4155 (PN SIKAFLEX-227).
Here’s a table with the various HEMTT A4 models:
