ASSEMBLY/DISASSEMBLY HELICAL BEVEL

REDUCER (RHB)

Please follow the instructions outlined below when assembling

and disassembling this unit. Failure to follow the instructions as

outlined may result in damage to the gear unit or to the machine's

drive shaft. For ease of assembly, it is recommended that the

machine's drive shaft be chamfered. DO NOT HAMMER THE

GEARBOX SHAFT ONTO THE MACHINE'S DRIVE SHAFT.

The machine's drive shaft should be produced in accordance

with the dimensions shown on the accompanying Table 5 or 6.

ASSEMBLY

All shaft mounted gearboxes are furnished with A) Retaining

Ring, B) Keep plate, C) Retaining Bolt, D) Spring Washer, E) Dust

Cap and Anti-Seize as shown in the finished assembly, Figure

4. Apply the anti-seize onto the customer shaft before installing

reducer onto the shaft. The gearbox is pulled onto the shaft by

means of a threaded rod and nut assembly as shown in Figure

3 below. The threaded rod and spacer are not supplied. The

threaded rod (M) is specified in Table 5 or 6. After the gearbox

has been pulled completely onto the machine shaft firmly against

the machine shaft's backing shoulder, it must be locked in place

with the retaining bolt tightened to the tightening torque shown in

Table 4.

DISASSEMBLY

Prior to disassembly, the dust cap, retaining bolt, spring washer,

keeper plate and retaining ring must be removed. For ease of

disassembly, it is recommended that the following tools be made

and used as described: The round keyed nut (A) is inserted into

the free space between the retaining ring in the gear unit's hollow

shaft and the end of the machine's drive shaft. The removal

bolt (B) is screwed into the nut (A) which presses a disk (C)

against the machine's drive shaft. The resulting force pushes the

gearbox off of the machine's drive shaft. Reference Figure 5 for

the disassembly arrangement.

NOTE: The retaining bolt supplied with the gear unit cannot be used

for this purpose and must be replaced with the bolt specified in Table

5 or 6. The round keyed nut and disk should be made from 1045 steel

and removal bolt should be a minimum of SAE Grade 5.
