Engineering Workshops
The in-house Cylinder Head & Engine modification department works on a philosophy of continual development, drawing on a 50 year heritage, providing Mini engines & components of the highest quality.
Cleaning & Inspection of Parts
All major engine components that are to be used go through an intensive cleaning process, this includes chemical dip, high pressure spray wash system, abrasive cleaning and final rinsing to flush all debris. Each component is then meticulously inspected for wear, stress cracks and damage, and measured for size, ovality, taper and aligment. Any component not meeting specification or tolerances is discarded.
Cylinder Block Remanufacturing
Bolt and stud threads are cleaned. Any damaged threads are replaced. The cylinder blocks are rebored and then honed to give the essential cross hatch micro finish. All gasket surfaces are machine refaced producing the correct surface finish and accurate deck height. New cam bearings, core plugs and oil gallery plugs are then fitted and the block is painted in the colour of your choice, (British Racing Green, Red, Black or Blue) using special high temperature engine paint.
Crankshaft Remanufacturing
Crankshafts are crack tested, the journals are reground to the next undersize then micro-finished polished to exact tolerances. All surfaces are then re-measured and checked, oil galleries
de-burred and thoroughly cleaned. Finally, each crankshaft is dynamically balanced to ensure smooth and efficient running.
Conrod Remanufacturing
All conrod bearing housings are measured for size, ovality and taper, any non-conforming items are discarded. Every conrod is checked for alignment, weight graded into engine sets, then finally balanced.
Cylinder Head Remanufacturing
The cylinder heads are cleaned in an additional process to ensure all old carbon deposits are removed. All valve guides are renewed, valve seats are recut (replaced if required) to ensure correct seating and position. All valves are examined for damage, head thickness, stem wear and replaced or machined.
Rocker and block faces are surface ground to the correct tolerance, ensuring a perfectseal with the gaskets. Painting process is then completed to the colour of your choice, (British Racing Green, Red, Black or Blue) using special high temperature engine paint. Finally, the cylinder head is assembled completely with valve springs, top caps, collets and valve stem oil seals, ready for fitment.
Final Assembly
Once all the machining work has been completed and passed, the engine is then assembled by one of our skilled technitions, using all new pistons including rings, crankshaft bearings, thrust washers, timing chain and tensioner (where applicable), oil pump, rocker shaft, pressure release valve and spring, gaskets, oil seals and oil filter.
All new components have been selected for their durability, reliability and are sourced extensively from the original OE manufacturers where ever possible. All O.E torque settings are adhered to during assembly.
