Engine Reconditioning Process

On arrival we allocate a job number. All engines are completely dismantled, all components are tagged with the job number and then are put into the hot tank to be chemically cleaned. When they are cleaned, they are crack tested and measured to OEM tolerance. After inspection we prepare a full report and quotation to advise you of the cost to recondition your engine. Following approval of the quotation, all the components are taken to respective work stations where they are reconditioned.

Cylinder Head Inspection & Repair Process

After dismantling, we chemically clean and inspect checking valves and valve guides, retainers and collets condition and test valve spring pressures.

The cylinder head core is checked for height, straightness, hardness and pressure tested in a submersible pressure tester checking for any cracks or porous leaks and all threads are checked.

Cylinder head failure can cause several problems such as poor performance, rough running and engine overheating.

Crankshaft Inspection & Repair Process

Crankshaft failure will start as a slight noise gradually becoming louder which, If not rectified can cause major damage to the engine.

The procedure for crankshafts starts with crack testing, measuring against OEM specifcations and checking for straightness.

After the testing procedure, the crank is ground to the first possible undersize.
