Main Bearing Housing Preventive Maintenance

ELECTROCUTION HAZARD—High voltage is present inside electric boxes, mo-
tors, and many other components. Power switches on machine disable only
control circuit power in certain boxes. You can be killed or seriously injured on
contact with high voltage.

☞

Lock OFF and tag out power at the wall disconnect before servicing.

ENTANGLE AND CRUSH HAZARD—Belts and pulleys can entangle and crush
body parts.

☞

Lock OFF and tag out power at the wall disconnect before servicing, except
where specifically instructed otherwise in this section.

☞

Permit only qualified maintenance personnel to perform these procedures.

Lubrication Procedures

—See the appropriate main bearing assembly drawing (if provided) during this

procedure (see Table of Contents).

1. Remove the console top by prying out the four plugs from each corner on the top of the machine and remov-

ing the four bolts. Remove the belt guard.

2. Remove the drain plug on the bottom of the main bearing housing and allow the bearing housing to drain

completely. Inspect the leak-off, drained oil, and magnetic drain plug for water and/or metal particles. Water
and/or metal particles can indicate worn or damaged seals and bearings. See “REPLACING MAIN BEAR-
INGS AND SEALS,” if provided (see Table of Contents). Install the drain plug.

3. Locate the two 1/2" plastic tubes secured to the frame. Clean the surrounding area and remove the cork

stoppers from each.

MALFUNCTION HAZARD—Oil spilled on components may cause machine malfunction.

☞

Refill bearing housing carefully.

MACHINE DAMAGE HAZARD—Mixing incompatible lubricants will result in se-
vere machine damage.

☞

DO NOT mix different base lubricants.

☞

Before using a non-specified lubricant, consult the lubricant manufacturer
to determine compatibility.

4. Strictly following lubrication specifications, refill the bearing housing. After refilling the bearing housing,

reinstall the cork stoppers and clean any excess lubricant from the machine.
