ON JOB (OJT) TRAINING FOR OVERHAUL PERSONNEL


On Job (OJT) Training for overhaul personnel

 

Functions

The following personnel are required to undertake D 30 howitzer overhaul to the required level:

  • Welder
  • Lathe operator
  • Hydraulics technician for counter-recoil mechanism and recoil brake
  • Specialist in overhaul of breechblock and semi-automatic loader
  • Specialist in overhaul of cheeks and upper/lower carriage
  • Specialist in overhaul of chassis and braking system
  • Specialist in overhaul of barrel, breech and cradle assembly.
  • Electrical equipment technician
  • Gun sight specialist
  • Quality controller
  • Assembly and disassembly specialist

Expertise levels

  • Each individual should be familiar with both the theory and practice of the following:
  • Structure and technical characteristics of the D30
  • Operating principle and structure of their specific components
  • List of equipment and tools
  • Sequence of disassembly and assembly of components
  • Troubleshooting and fault detection
  • Safety measures to be observed during overhaul

 

In order to achieve this trainees will require the following basic skill sets:

  • To be able to read technical procedure manual and apply the procedure as stated.
  • Be familiar with the instruments and tools used for repair/overhaul.
  • Be able to prepare/ update service record for the gun or component concerned.
  • Be familiar with the correct use of general-purpose equipment – lifting and handling gear, cleaning equipment etc used in the overhaul process.

Organization of Training

Whilst it is appreciated that the aim is to carry out as much training as possible on an OTJ basis considerations of practicability and safety dictate that some degree of theoretical instruction will be required to bring trainees to the level of competence necessary for them to function effectively on the overhaul line.

In terms of basic qualifications the major requirements for trainees are as follows

  • technical secondary education;
  • not less than 2 years prior experience working with technical equipment.

 

For those in this category it is proposed to organize trainees into two groups of 12 individuals and each group will undertake a maximum of four hours of theoretical training or six hours of practical training on any one day. Practical training will commence after trainees have demonstrated an understanding of the theoretical elements.

 

Theory Training

 

This will take place in a classroom environment equipped with tables, seating, white-board, and overhead projector.

Documentation will be provided on overhaul and operation of D30 supplemented by illustrative wall posters.

 

Training will be provided by a combination of short lectures and classroom discussion. Tests on theoretical knowledge will be made on a regular basis to determine candidate’s suitability to proceed to the practical stage.

 

Practical Training

 

Practical training will take place on the established overhaul line, the content and structure of which is dealt with in the main proposal.

 

After completion of the initial five howitzers under close supervision, each group of trainees will undergo practical examination carrying out an independent overhaul of a further three howitzers.

For this purpose an examining committee will be formed, which in addition to the instructor for each discipline will also include customer representatives.

Technicians who successfully pass this practical examination will be nominated as artillery mechanical engineer level 3.

With further on the job training it is anticipated that able individuals will progress to level 6.

Trainees will also take part in post overhaul testing of the howitzer at the nominated firing range in the presence of customer representatives/mentors.

Lathe operators and welders will require additional practical training, which can be provided during the overhaul process. (OTJ)
