Bands are centered on drum by the adjustable brake guides (9) mounted on the top cover (7) as shown in Fig. A29. Test freedom of rotation of wheel after top cover is installed to make sure that guides (9) are not forcing
BRAKES Brakes shown in Figs. A28 and A29 are external hand type contracting on drums located in the final drive housings and mounted on the main axle (bull pinion) shafts. Brake eyebolts (11) are connected to brake pedals by rods and a brake pedal cross-shaft mounted in the frame. Individual brake locking cams (10) are provided on front of final drive housing on some TTiodehi, ADJUSTMENT 260. To adjust brakes, remove upper cover and tighten nut (2) on adjusting
Paragraphs 260-271 top ends of bands against drums thus throwing bands eccentric tci drum and causing drag. Guide should just contact the adjusting bolt when cover is installed. Adjust the pedals by means of the brake connecting eyebolts (11) so that they both have the same amount of free travel.

In models A, BF, BG shaft whUe the belt pulley shaft (29) is and R the pto external shaft is driven from driven from a separate bevel pinion (13) the end of the transmission countershaft on the drive shaft which meshes with the (input shaft) via a coupling shaft (22—Fig. bevel gear (30) on the belt pulley shaft.

The front bearing cup (18— Fig. A30) and snap ring (20) wiU remain in the housing. If this cup is removed for any reason, be sure to mark and keep together the shim or shims (19) located between the cup and the housing. These shims are used to control the mesh position of the combination spur and bevel gear (12). The belt pulley shaft can be removed after removing the pto shaft by
