Preventive Maintenance
1.
Lubrication Guidelines
As required by the warranty, to ensure safe operation, and to achieve optimum performance and
service life from Milnor® washer-extractors, the schedules, instructions, and precautions herein
must be strictly followed.
WARNING 1 : 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.
• Insure belt and pulley guards are in place during service procedures.
• Permit only qualified maintenance personnel to perform these procedures.

36026V5J Main Bearing Maintenance
36026V5J main bearing housings are oil-filled and require periodic draining and refilling (see
below). 42026V6J bearing housings are grease filled and require periodic greasing of seals and
bearings (See “Lubrication Precautions” and “42026V6J Main Bearing Maintenance” below).
See the appropriate “MAIN BEARING ASSEMBLY” (see Table of Contents) during this
procedure.
1. Remove the drain plug on the bottom of the main bearing housing and allow the bearing
housing to drain completely (Figure 4). Inspect the leak-off, drained oil, and magnetic drain
plug for water and/or metal particles. Install the drain plug. Water and/or metal particles can
indicate worn or damaged seals and bearings.
2. Locate the two 1/2" plastic tubes secured to the electrical control chassis (Figure 5). Clean the
surrounding area and remove the cork stoppers from each.
3. Strictly following lubrication specifications, refill the bearing housing. After refilling the
bearing housing, re-install the cork stoppers and clean any excess lubricant from the machine.

Lubrication Precautions (42026V6J only)
CAUTION 2 : Bearing and Seal Damage Hazard —Mixing different base greases can
cause bearing and seal damage.
• Consult lubricant manufacturer before using non-specified lubricants.
WARNING 3 : Entangle and Crush Hazard —Belts and pulleys can entangle and crush
body parts. Power is ON and cylinder is turning during the following procedure.
• Insure belt and pulley guards are in place during service procedure.
1. Do not use a pneumatic grease gun. Pump grease slowly while cylinder is rotating. Take 10-
12 seconds to complete each stroke. A grease gun can build up extremely high pressure
which will force the seals out of position and cause them to leak, even though both the seal
and bearing cavities are equipped with spring loaded relief plugs.
2. Apply the quantity of grease called for in the checklist. Over-lubrication can be as damaging
as under-lubrication. Where quantities are stated in strokes, one stroke of the grease gun is
assumed to provide .0624 fluid ounce (by volume) (1.77 grams) of grease. Therefore, one
fluid ounce (28.3 grams) of grease would be provided by 16 strokes of the grease gun.
