Omega Pistons

Made for us in the UK by Omega Pistons (www.omegapistons.com).
The pistons are not a replica of the original, but a new design using the best technology available today. They are made from a forged (rather than cast) alloy and incorporate a solid skirt (unlike the original split-skirt design with a modern three ring pack and feature a lighter gudgeon pin.

Our Omega pistons have been designed and extensively tested using state of the art techniques:
Design - Mass distribution and proportioning of the crown, improved gudgeon pin bosses and braced skirts
Material selection - Aerospace grade forging stock giving a lighter but stronger piston
Heat treatment - Optimised for strength and durability
Machining - CNC machines used at all stages allowing greater control of tolerances. No need for balancing or matching up of the individual pistons
Finishing operations - Honing (gudgeon pins and pin boss bores) and a proprietary coating
Gudgeon pin preparation - much higher specification material used than standard pins, improved CNC machining and optimised heat treatment
Modern three ring pack – with a life expectancy of 100,000 miles

Traditional less-precise piston manufacturing techniques, typical of the period 65 years ago in which the OEM piston was designed, can lead to piston “rock” which contributes to piston ring and groove wear. This leads to higher oil consumption, increases in gas blow-by and lower cylinder compressions often associated with poor starting. Omega Pistons do not suffer with such issues.
Our research has established that most of the B60 engines have previously been worked on and this usually involved re-facing/decking/skimming of the cylinder block and/or cylinder head, on average by 0.010". Our pistons are 0.010" shorter than original in order to account for this machining which helps maintain the correct compression ratio.
