We are also able to provide in-house crankcase line boring facilities, where shell bearings are used to replace the original white metal bearings in the crankcase. In many instances this requires the replacing of the main bearing caps with new precision-made aluminium caps including studs or bolts and for some models, new rear oil seals in the sump also.

It is appreciated that in some instances where it is not possible for customers to send their crankcase (perhaps due to long distance/overseas etc.), we can supply our innovative ‘Crankcase Conversion Kit’, (comprising new caps, bolts studs etc.) which enables the customer to use an engineering shop locally to them to complete the works using our tried and tested components. We will advise you whether this particular service is applicable for your model when you make your enquiry.



Customers are reminded that Phoenix Crankshafts Ltd manufactures automotive crankshafts and con-rods and does not supply assembled bottom-ends ‘ready for use’. With regard to our line-boring service, crankshafts are only fitted into the crankcase for delivery as proof that the crankshaft freely rotates in the main bearings and for ease of transport and product safety.


It is the responsibility of the customer and/or engine builder to ensure that the crankcase(s) are thoroughly cleaned and free from any swarf or debris. Furthermore, checks should be made to ensure all oilway plugs etc. are properly fitted to the crankshaft and that following these initial steps that everything else is fit for purpose, before re-assembly.


It must be noted that once fully assembled, the engine performance falls under the responsibility of the engine builder and not Phoenix Crankshafts Ltd.
