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

transmission housing is self-evident. To disassemble the removed unit, follow the procedure outlined in paragraphs 271, 272. 271. DISASSEMBLY. To remove the pto shaft, first remove the bearing cap 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 that they both have the same amount of free travel.
PTO & BELT PULLEY
A unit contaimng a pto shait only, or a pto shaft and a belt pulley is optionally avaUable on all models. In models A, BF, BG and R the pto external shaft is driven from the end of the transmission countershaft (input shaft) via a coupling shaft (22—Fig. A30) called the drive shaft. A spur gear (25) mounted on this shaft, drives the combination spur anii bevel gear (12) on the pto external shaft. The bevel toothed portion (not visible in Fig. A30) of gear (12) meshes with the bevel gear (46) on the inner end of the bctlt pulley shaft.
The bolt pulley and pto unit on the model V employs a somewhat similar drive as shown ill Fig. A32. In this model, however.

brake connecting eyebolts (11) so (5—Fig. A30) and shims and gaskets from the rear face of housing. Using a puller with jaws of same engaged over the front face of gear as shown in Fig. A31, press the pto shiaft out of the gear. 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).
