SFG10E ELECTRIC SURFACE GRINDER — OPERATION AND PARTS MANUAL — REV. #1 (07/16/07) — PAGE 34
Do not install an elastomeric mount without the use
of an approved lubricant. Installation without an
approved lubricant can produce tears in the mount,
resulting in substandard operational performance
and service life.

9) Support the elastomeric mount, socket and mounting
plate as depicted in FIGURE 50. The mounting plate
must be suspended from the arbor press to allow the
mount to clear when the pressing process is completed.
A short section of 1-1/2 inch inside diameter steel tubing
can be utilized for this purpose. Using the arbor press,
apply a steady force in a straight line direction to the
mount until it fully penetrates the cavity in the mounting
disc. Do not attempt to push the elastomeric mount
through the mounting disc with excessive force.
Damage to the elastomeric mount will result.
10) Reassemble the mounting disc to the transmission shaft.
11) Reassemble the mounting plate to the mounting disc.
12) Reassemble the aluminum multi-accessory disc to the
mounting plate.
13) Check to determine that the replacement elastomeric
mounts allow for proper position of the aluminum multi-
accessory disc. If the elastomeric mounts are not
properly positioned, they will require removal and
reinstallation. The removal process can produce tears
and abrasions in the mount that will require new
replacements.

LUBRICATION REQUIREMENTS
Parts Required:
1 each, standard grease gun filled with one of the following:
ESSO Beacon 325, Shell Alvania #2, Chevron SRI, or
equivalent.
1 each, container of dry film lubricant.
1) Lubricate the caster wheel bearings with a dry film
lubricant only. Dry film lubricants dry immediately upon
contact. Use sparingly. Excess lubricant will attract the
fine grained, powdered materials described and directly
affect bearing service life.
MAINTENANCE/SERVICE
Do not lubricate the caster wheels with any type of
grease material. Grease will attract foreign material
accumulations that can accelerate bearing wear.

2) The transmission gears are supported by extra capacity,
ball bearing units. Bearings are lubricated at the time of
manufacture and do not require additional servicing
when placing the unit in initial service. Zerk grease
fittings can promote improper service schedules and
an excessive amount of over lubrication. Excess
grease escaping from around the bearing insert seals
will attract foreign material accumulations that can
drastically shorten their service life. Excessive amounts
of grease in the bearing race cavity can actually
increase friction and resulting heat increases that can
also dramatically shorten bearing service life.
