Engine Reconditioning in Durban

Full automotive machine shop services in Durban — engine reconditioning, crankshaft and camshaft grinding, cylinder block machining and conrod resizing. All makes and models. Part of the CRS Group, engineering for South African industry since 1977.

Engine machining and reconditioning

We are a fully equipped, up-to-date automotive machine shop. Whether you need a single component machined or a complete engine rebuilt, the work stays on our premises from strip to reassembly.

Work we take on every week includes:

• Cylinder block machining — boring, honing, decking and skimming
• Line boring — main bearing tunnel restoration to original alignment
• Re-sleeving — restoring worn bores to original specification
• Conrod resizing — big end reconditioning and small end bush replacement
• Cylinder head overhaul — skimming, resurfacing, valve and seat work
• Bell housing machining — alignment and face restoration
• Engine rebuilding — complete strip, machine, measure and reassemble

Crankshaft and camshaft grinding

Precision grinding and polishing of crankshafts and camshafts, restoring journals and bearing surfaces to original specification.

• Crankshaft grinding and regrinding — main and big end journals to undersize
• Crankshaft polishing — correct surface finish for bearing life
• Camshaft grinding and polishing
• Straightening — correcting run-out before machining
• Crack testing — before we invest your money in machining

Diesel and petrol, passenger vehicle through to heavy commercial and industrial engines.

Recondition or replace — whichever costs you less

Service exchange is the easy answer, not always the right one. For older engines, imported units and anything with a long lead time, reconditioning is usually faster and cheaper — and you keep the engine that matches your vehicle.

We measure first and quote honestly. If a component genuinely can’t be saved, we’ll say so rather than machine it and hope.

Why CRS Group

Established 1977. Nearly five decades machining and repairing automotive and industrial components for South African industry.

Eight specialist divisions under one roof. Engine reconditioning, general engineering, metal stitching, specialised welding, micro welding, component manufacturing, 3D scanning and CAD/CAE modelling. If your job needs more than one discipline, it doesn’t leave our premises.

Turnaround that competes with service exchange. Downtime is the real cost of a failed engine. We’re set up to get work back to you quickly.
