Date: October 22, 2009Bearing lubrication is required for controlling wear and cooling the bearings. Proper maintenance of these systems will help sustain the life of the bearings and lower the chance for costly repairs. The minimum service period for these items is every 12 months, however more frequent maintenance may be required depending on the amount of machine utilization and operating environment.A NOTE BEFORE BEGINNING: “Optional” items will only be completed if this particular machine is so equipped.This document covers the following items:1. Drive Motor Bearings2. Tailstock Cam Followers3. Universal / CV Joints4. Inertia Lift Trolley5. Inertia Shaft Bearings6. Inertia Lube Pump7. Guide Ways8. Cooling Blower Shaft Bearings9. Cooling Blower MotorRequired Materials:1. Grease Gun2. Screwdrivers (both phillips and straight)3. Set of hex key wrenches (Allen wrenches)4. An assortment of lubricants (Located in chart at the end of this document)5. Clean RagsGeneral Maintenance Procedure:1. Close all software applications turn off the computer and then the control console.2. Turn off main power and install a lockout on the main disconnect switch.3. Inspect the system for any obvious damage or signs of fretting.4. Clean the old grease from the area and the grease fitting.5. Pump a few ounces of grease into the fitting. In some cases you will continue to pump greaseuntil you see the old grease exit the system and new grease begin to exit.6. Clean the area and remove any excess grease. Reference the detailed maintenance procedurebelow.7. Replace any grease fitting covers or grease drain plugs.8. Replace any guards that were removed for service.9. Turn on the control console and start the control software.10. Ensure that the machine controls can be reset and that all systems are functional.Detailed Maintenance Procedures:1. Drive Motor Bearings:There are bearings on each end of the motor. There are grease fittings on top, and a discharge port on the bottom. At the discharge port, remove the screw.Date: October 22, 2009GreaseFittingPump grease through the grease fitting, using EP1 grease or equivalent, until fresh grease comes out of the discharge port. Replace screw.Modern motor designs usually provide a generous supply of lubricant in tight bearing housings. Lubrication on a scheduled basis, in conformance with the manufacturer's recommendations, provides optimum bearing life.Thoroughly clean the lubrication equipment and fittings before lubricating. Dirt introduced into the bearings during lubrication probably causes more bearing failures than the lack of lubrication.2. Tailstock Cam followers:Inspect and grease cam followers as needed, add lubricant to Cam Followers until it appears at the bearing seals, using EP1 grease or equivalent.WARNING: Too much grease can over-pack bearings and cause them to run hot, shortening their life. Excessive lubricant can find its way inside the motor where it collects dirt and causes insulation deterioration.Remove Grease PlugDate: October 22, 2009Grease Fittings3. Tailstock Screw Drive Bearings:There are 2 bearings; one is located under the cover and one under the brake enclosure. Inspect bearings. Grease bearings using EP1 grease or equivalent.CoverGrease Fitting4. Universal/CV Joints:Inspect all Universal/CV Joints for worn parts. The u-joints and telescoping assembly must be lubricated prior to start-up. Use quality lithium base grease.Add lubricant to universal joint until it appears at all four bearing seals.Lubrication intervals should be every 500 hours of normal service or every 200 hours ofcontinuous duty service. Adverse conditions such as extreme temperature, severe shock loading or corrosive environment may require special grease and/or greasing intervals.Date: October 22, 20095. Inertia Lift Trolley:Inspect and grease cam followers as needed, add lubricant to Cam Followers until it appears at the bearing seals, using EP1 grease or equivalent.Grease Fitting6. Inertia Shaft Bearings:Periodically remove Pillow Block Cap and inspect the bearings. Over time, due to heat and wear the grease will break down to a liquid and will insufficiently lubricate the bearing, when thisoccurs, remove all the old grease, clean bearing housing and cap. Repack bearing with EP1grease or equivalent.Date: October 22, 2009Pillow BlockCap7. Radial Load Guide Ways:These are located on the tailstock for a Dynamic Wheel Load. There is 2 Star Guide Waysand 4 Thompson Bearing Blocks that have grease fittings, located behind the plate in the picture below. Lubricate the 4 bearing blocks using EP1 grease or equivalent.Guide Ways8. Cooling Blower Shaft Bearings:Locate and inspect the cooling blower shaft bearings. Some might be behind a guard, as shown below. Add EP1 grease or equivalent as needed.Date: October 22, 2009Grease Fittings9. Cooling Blower Motor:Most motors have sealed bearings and do not require maintenance; however there is a few that do have lubrication points, so inspect the motor to see which style it is. After completingmaintenance turn on the cooling air and check for noisy bearings.10. Inertia bearing lube pump:This pump is used to lubricate and cool the inertia bearings. The proper operation of this pump is critical to life of the inertia bearings. Verify the tank is at proper level and the flow control valves are set to 0.2 GPM. The oil should be sampled to verify contamination has not occurred. Contamination could be the result of a damaged bearing or could lead to the bearing damage.Note. See Oil sample maintenance Procedure document.Example1 Example2BELOW IS A TABLE TO SHOW WHAT KIND OF OIL/GREASE TO USE FOR DIFFERENT APPLICATIONS.Date: October 22, 2009EP1 GreaseThe National Lubricating Grease Institute (NLGI) Grade = 1.
