Installation, Operation and Maintenance Manual E-CLCL-CC002-E2

May 2017

HEVC 5005

2.2

Mounting considerations

2.2.1

Shaft alignment must be within the tolerances

indicated in the Alignment section of this manual.

Caution

Operation with shaft misalignment exceeding the

limits indicated in this manual will result in

accelerated wear of the HEVC components.

2.2.2

The element must be protected from contamination

from oil, grease or excessive amounts of dust.

Caution

Oil or grease contamination will result in a reduction

of developed torque. Excessive dust contamination

may result in incomplete engagement. Either of

these conditions will result in clutch slippage and

overheating.

Caution

All rotating equipment must be guarded to comply

with applicable safety standards.

2.2.3

All mounting fasteners must be of the proper size

and grade, and torqued to the appropriate value.

See Table 1.

Warning

Use only the proper grade and number of mounting

fasteners. Using commercial grade fasteners

(Grade 2) in place of Grade 8 fasteners (where

called for) may result in failure under load,

causing personal injury or equipment damage.

2.3

Mounting spider and drum hub

2.3.1

The spider and drum hub are bored for a press fit

onto their respective shafts. The interference is

approximately 0.0005 inch per inch (0.0005 mm/mm)

of shaft diameter.

2.3.2

Ensure the shaft is clean and free of nicks or burrs

and check the shaft and bore diameters for proper

fit dimensions and are also clean and free of nicks

and burrs. Tap the key into the keyway, making sure

it bottoms, and apply a light coat of light weight oil to

the shaft and key.

2.3.3

Heat the drum hub or spider uniformly to a maximum

of 250°F (121°C) to expand the bores.

Caution

It is recommended the drum hub or spider be heated

in oil or an oven; however, torches may be used.

Use several with “rosebud” (broad-flame) tips and

keep them moving to avoid "hot spots". Check bore

temperature with a temperature reading device

frequently to avoid overheating.

2.3.4

Slide the heated drum hub or spider onto the shaft.

Hold in position and allow them to cool. It is helpful

to put a mechanical stop device onto the component

face to prevent “over-shooting” the proper axial

location if there is no physical stop on the shaft such

as a machined shoulder.
