I have been asked several times if i can supply replacement shell bearings for the engines, unfortunately these are not now available in the after market which leaves owners with a serious problem.
One solution is to invest in a new Crankshaft & find bearing shells to fit the housings, this is expensive.
It might be possable to have a special batch of bearings produced but this is going to be expensive & will require the support of the club & owners to fund it, i am investigating this & will make a proposal if i am able to get a manufacturer to quote!
Another option which may be possable is to find some existing shells which could be adapted to fit the housings which would offer the journal diameters required, i have some details i am investigating but it will probably require block line boring of the main housings & grinding the journals to suit.
It would help if the owners could indicate what solutions they have devised to this problem.
