WORKSHOP PREPARATION

This is a customized workshop on one or more of your machine centers. Before the training can take place, one of GPM's consultants will conduct a sight survey on the equipment.

 At this time, the original hydraulic schematics are compared to the existing machine. Any changes or modifications are made to ensure that the schematics are accurate. If the original prints have been lost, our consultant will then make a new one. Pictures will be taken of each component to be include in a troubleshooting manual.

Troubleshooting Manual.

A troubleshooting manual and P.M. checklist is developed from your schematics. In the manual you will find a complete description of each hydraulic component on the machine and troubleshooting tips. You will have colorized flow charts which integrate the electrics and the hydraulics together.

WHAT THE STUDENTS LEARN

• Hydraulic Safety.

• How to troubleshoot each component.

• Reading and troubleshooting from the hydraulic schematic.

• The basic function of each component on their hydraulic system.

• The three tests that can be performed to determine if the pump is bad before it is changed.

• A step by step pressure setting procedure that will reduce heat, shock and leakage.

• The right and wrong methods of increasing the speed of the machine.

• How to pre-charge an accumulator properly for maximum speed and/or shock absorption and the two quick checks to make to verify that it is operating properly.

• How to troubleshoot and adjust the null of a servo and/or proportional valve.

• The specific preventive maintenance checks that need to be done to determine component wear and by-passing.

WHAT THE STUDENTS RECEIVE

• Our colorized Maintenance Basic Hydraulic Troubleshooting Manual. (Over 200 pages of practical hydraulic troubleshooting information)

• Their Troubleshooting Machine Specifics Hydraulic Manual.

• Fluid Power Data Book.

• A certificate of completion.

HOW YOUR COMPANY WILL BENEFIT FROM THE TRAINING 

• You will have updated schematics on your machine in a colorized troubleshooting manual which contains a description of each hydraulic component, troubleshooting tips and colorized flow charts. The electrics and hydraulics are integrated together and shown as machine cycles.

• You will have a customized preventive maintenance schedule. You will have a  P.M. list that was completed during the training and a blank P.M. list that can be used for future troubleshooting.

• Laminated component tags will be placed on your hydraulic system for fast identification when troubleshooting.

• Your personnel will have increased hydraulic knowledge and troubleshooting skills.

WORKSHOP DURATION

It takes1-2 days to teach one machine center. This workshop can be 3 or more days in length depending on the number of machines that you want to be included in the workshop.

WORKSHOP DESCRIPTION

• 3-4 hours of classroom time is spent teaching the student the function of each component, how to troubleshoot each component, reading the hydraulic schematic, troubleshooting from the schematic and learning the machine cycles.

• 4-5 hours is spent in the plant identifying, locating and tagging each component. The students also:

• Set pressures.

• Check for pump wear.

• Check accumulators' precharge.

• Make various heat tests.

• Identify the causes of leaks.

• Record other machine specific P.M. information.

• Return back to the classroom and review the P.M. and answer any additional questions.
