The Mini Sport 9 Step Remanufacturing Process...
Here at Mini Sport, our engine remanufacturing process consists of 9 meticulous stages which contribute to the performance & reliability of your remanufactured engine.
These stages are as follows…
1. Dismantle
Every engine and component is stripped, removing and discarding all gaskets, oil seals, bearings and pistons - ready for the next stage.
2. Cleaning
All major engine components undergo an intensive cleaning process which includes a chemical dip, high pressure spray wash system, abrasive cleaning and a final rinsing to flush all excess debris.
3. Inspection Of Parts
Following the cleaning process, parts are meticulously inspected for wear and damage. Parts are also measured for size, ovality, taper and alignment. Components that do not meet specification are replaced.
4. Cylinder Block Remanufacturing
Bolt & stud threads are cleaned. Damaged threads are replaced. Cylinder Blocks are then rebored and honed to give the essential cross hatch micro finish. All gasket surfaces are machine refaced
5. Crankshaft Remanufacturing
Crankshafts are crack tested, the journals are reground to the next undersize then micro-finish polished to exact tolerances. All surfaces are re-meausred. oil galleries de-burred and cleaned.
6. Conrod Remanufacturing
All conrod bearing housings are measured for size, ovality and taper, non-confirming items are discarded. Every conrod is checked for alignment, weight graded into engine sets, then dynamically balanced.
7. Camshaft Remanufacturing
Measured for straightness & wear. Cam profiles are then reground to the original valve timing/lift specifications. Camshafts are finally heat treated by a nitrocarburising process for a longer service life. The journals can then be polished if required for finish.
8. Cylinder Head Remanufacturing
The cylinder heads are cleaned to ensure all carbon deposits are removed.Valve guides are renewed, valve seats are recut or replaced and examined. Cylinder heads are painted with high temperature engine paint.
9. Rocker Assembly
The complete rocker assembly is stripped, cleaned, checked and machined where necessary and then rebuilt using a new rocker shaft.
