Machinery Service Tips
1. Be updated of large machinery operator training
Many types of large machinery have multiple operators. Ongoing inspections on any checklist should be overseeing the correct operation of the equipment.
Large machinery needs to be inspected as soon as it is purchased. Operator training is normally done at that point, but training needs to be kept up.
Operator manuals should be revised for the specific work situation. They can be rewritten in a language that can be better understood. A short manual can be provided to each operator for simpler reference. If you operate in a paperless environment, you can rest assured operators use the most updated version of each manual.
2. Put lubricants to the test frequently
Lubricants reduce friction around moving parts. A schedule of good lubrication maintenance extends the life span of large machinery equipment and parts.
Lubrication is an important part of maintenance checks. Look for signs of too much oil or grease build-up on pistons. Check for leaks around oil seals.
Be sure to use the right lubricant. There are specific kinds of oil and grease for every component. Check the manufacturer’s recommendations.
Getting the lubricants checked is a good way to diagnose problems with large machinery. Experts analyze particles in the used oil. The makeup of any contaminants will indicate which part may be suffering from wear or breakdown.
3. Check for wear
Vibration, shock, high temperatures, friction and age all contribute to the breakdown of parts in heavy machinery.
- Vibration can come from gears and belts that are out of alignment
- Shock can come from accidents and from poor operator technique
- High temperatures can come from extended use, friction, poor lubrication and worn parts, among other reasons
- Age affects many key components. Over time, belts will warp. Seals will dry and crack. Bolts will loosen and stretch out of shape. Age is a factor to monitor in equipment.
Should you discover wear and tear on any moving parts within your heavy equipment, be sure to quickly perform the necessary replacement of any worn parts.
4. Keep large machinery clean, and maintain a clean environment
There are many seals and filters in place on heavy machinery to keep working parts clean and free of contamination. Seals should be inspected regularly to make sure they’re in good condition. Filters should be inspected and changed regularly. Breathers should be kept clean to avoid creating a vacuum in the cab which will suck contaminants into the cab. The electronics in the cab are susceptible to breakdown if contaminated. This impacts the clutch, for example.
Large machinery should be stored in a shed or other building if at all possible. Exposure to wind and weather can lead to rust and rot. The machinery should be run periodically if it is not in use.
5. Have a maintenance and repair schedule, and keep good records
Fluids, tires, tracks and electrical systems are among the components that have to be checked regularly for preventive maintenance. Know what needs to be inspected and when. Here are some examples.
- Power transmissions have many moving parts that need to be maintained in top condition. Gearboxes need to be checked for lubrication, vibration and damage to parts.
- Friction materials, seals, gaskets and bearings all need to be inspected for wear and replaced. Gears and shafts usually last a long time and don’t need to be replaced often, if at all.
- Drive train components need constant monitoring. Check pulleys and v-belts on CVT transmissions for alignment and wear. Check sprockets for correct meshing with chains and for breaks.
- Test the oil to diagnose problems. Change filters frequently.
- Bearings keep great amounts of force running smoothly and are vital to large machinery performance. Check bearing lubrication often. Maintaining bearings well extends their life.
- Lubricate gears frequently.
- Do a seal check to prevent bearing raceway contamination.
- Run torque checks on the bolts. Bolts can elongate and creep over time.
