Responsible for the inspection, dismantling, repair, assembly, and testing of hydraulic cylinders used in industrial and mobile hydraulic applications. The technician must be capable of carrying out precision measurements, identifying component wear and damage, and ensuring cylinders are restored to the required specifications.

Key Responsibilities

• Dismantle and assemble hydraulic cylinders, including single-acting, double-acting, and telescopic cylinders, safely and correctly.

• Inspect cylinder barrels, pistons, rods, glands, bushes, seals, and other components.

• Identify wear, damage, corrosion, scoring, leakage, and other defects.

• Carry out accurate dimensional inspections using:

o Micrometers

o Bore gauges

o Vernier calipers

o Dial gauges

o Other precision measuring instruments

• Check cylinder barrel ID, piston OD, rod OD, gland dimensions, and required clearances.

• Perform cylinder barrel honing and rod polishing, ensuring the required dimensions and surface finish are achieved.

• Assist the machinist with machining of pistons, glands, bushes, and other cylinder components.

• Inspect and replace seals, guide rings, wear rings, bushes, and other consumables.

• Follow engineering drawings, specifications, tolerances, and repair procedures during the work.

• Maintain proper identification and traceability of components during dismantling, inspection, repair, and assembly.

• Be capable of carrying out Dye Penetrant Testing (DPT) for weld crack inspection.

• Have good knowledge of hydraulic seal materials, seal profiles, preloading requirements, and their applications.

• Carry out pressure and functional testing of hydraulic cylinders after repair, including:

o End-to-end testing

o Mid-position testing

o Pressure holding/leakage testing

• Record inspection measurements, findings, repair details, and test results accurately.

• Assist with troubleshooting and technical assessment of hydraulic cylinder failures.

• Support site work when required for cylinder inspection, removal, installation, commissioning, and troubleshooting.

• Maintain workshop tools, measuring instruments, machinery, and equipment in good condition.

• Follow all company HSE procedures and safe working practices.

• Maintain good housekeeping and workshop discipline.

• Work independently as well as effectively as part of a team.
