19. EQUILIBRATED ELEVATION MECHANISM ASSEMBLY (C)

Lubricate two lubrication fittings (55) with GAA (item 17, Appx D).

20. TRACK ADJUSTER (C)

Lubricant is under high pressure. Loosen bleeder plug slowly to avoid injury.

When increasing track tension, do not let track adjuster extend beyond 3-1/2 inches (8.89 cm) to

avoid track adjuster damage.

Check track tension on track adjuster (56). Clean lubrication fitting (57). Pump GAA (item 17, Appx D) into lubrication

fitting to increase track tension. Open bleeder plug (58) to decrease track tension.
