(See fig. 4-7.) 1. Front output shaft case. (See fig. 4-7.) m. n. o. 4-4.) 3.) Air cylinder assembly. (See fig. 4-6.) Companion flanges. (See fig. 4-5.) Draining transfer. (See fig. 4-4.) Positioning transfer on overhaul stand. (See fig. Handbrake drum and shoe assembly. (See fig. 4- AND ADJUSTMENT (MODEL T-136-27) the tests and 4-10. Lubrication. Tighten drain plug (fig. 4-2). Lay transfer on side with filler plug up. Remove filler plug and pour ½ pint of universal gear lubricant (GO), MIL-L-2105, through the plug opening. Install and tighten filler plug. Lubrication of the complete unit should be accomplished after installation. Attach a tag to filler plug giving instructions for filling before transfer is placed in service. Refer to paragraph 4-3 for transfer data and lubrication order (LO 9-2320- 209-12/1) for lubrication specifications. 4-11. Shift Test. a. Neutral. Place shifter shaft in neutral position (between low, shifter shaft out, and high, shifter shaft in). Turn input shaft by hand. Front and rear output shafts should not turn. b. High. Push shifter shaft in to shift to high position. Turn input shaft in clockwise direction. Rear output shaft should revolve in same direction. Front output shaft should not turn. c. Low. Pull shifter shaft out to shift to low position. Turn input shaft by hand and note if rear output shaft turns approximately one-half as fast as when in high position (step b). Front output shaft should not turn. d. Front Output pressure, check for steps b and c, both Shaft Air Lockup. Apply air sound of lock engaging. Repeat output shafts should turn. Remove air pressure and repeat step b. Front output shaft should be disengaged. 4-12. Handbrake Test. Pull handbrake lever (fig. 4- 2) to engage brakeshoes with handbrake drum. Release lever and note if shoe return spring pulls shoes free of drum. For in-vehicle handbrake lever adjustment, refer to TM 9-2320-209-20/1. 4-13. Handbrake Shoe Adjustment. a. If shoes do not clear brakedrum (para 4-12) check adjustment of shoe anchor pin. (See fig. 4-3.) If outer shoe is free on anchor pin, tighten bolt in shoe stop bracket to increase shoe-to-drum clearance. For in-vehicle adjustment, refer to TM 9-2320-209-20/1. b. To ensure brakeshoe assembly is correctly positioned on brakedrum, use spacer washers between brakeshoe assembly and rear bearing cover to obtain 1/16-inch of brakedrum extending beyond brakeshoe assembly. 4-11
