intervals specified in the Lubricants section of this document.

Check alignments of drive components regularly. Check chain

and belt tensions and hardware tightness periodically too.

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 tables 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

7. 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

6 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 8 for the

disassembly arrangement.

Please 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.
