M88A1…Keep Final Drive Sprockets On Track

Mechanics, the final drive hub sprocket’s threaded bolt holes on your M88A1 can strip or even break if you don’t do PM. That could leave your vehicle with a wobbly final drive sprocket.

Here’s how to keep those bolt holes in good shape and your final drive sprocket on track:

  • During semi-annual PMCS, inspect the final drive hub bolts. Re-torque loose bolts, NSN 5306-00-799-7722, to 225-250 lb-ft. Locking nuts, NSN 5310-00-225-6408 should be torqued to 70-90 lb-ft.
  • Only use those locking nuts once. If they’re loose or have to be removed, replace ‘em.
  • Always use a dab of GAA on the final drive hub sprocket bolts and locking nuts during installation.
