This, coupled with quick job turnaround times and components machined to OEM tolerances in a quality endorsed environment guarantees your engine will be produced at the highest possible standard.

Whether your needs are for resurfacing a cylinder head, or reconditioning a long engine for petrol, diesel, LPG or performance application, Reflex have the facilities, experience and capacity to professionally satisfy your needs.

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.

Conrod Inspection & Repair Process

Our process for reconditioning of conrods involves crack testing, checking small end and big end size and straightness.

After the testing procedure, the conrod is resized, small end bushes are replaced and pin bored.

Engine Block Inspection & Repair Process

The block inspection consists of checking cylinder condition, top deck, main tunnel and camshaft tunnel. Depending on the engine condition it will be rebored to the first oversize and top deck resurfaced.

Timing Components

Timing components are checked for wear to determine if replacement with a new timing kit is necessary.

Oil Pumps

Oil pumps are check for wear to determine whether we can rebuild with new components or if the pump should be replaced with a new oil pump.

Camshafts

Camshafts are measured, then linished or reground if the camshaft is deemed too badly worn, and replaced with a new billet.
