Crankshaft Bearings for 34 Standard 8 Engine

Posted by Russell James On 2008/8/4 7:03:14
Hi Pre War Team

A good friend has encountered some serious knocking coming from his 34 (1100) Standard Eight engine. Oil pan removal has revealed plenty of metal, big-end bearing damage, journal damage but fortunately no hole in the crankcase (you can be lucky)! We don't suspect main bearing damage but the crankshaft is coming out soon to fully investigate.

Options include re-babbiting of the main and big-end bearings.

Other option? I understand that later Super 8 320ci engine (37-39) had easy to obtain slipper bearings. Is it a viable option to machine the 34 320ci engine to fit the later bearings?

Or are there other bearing options?

(I have just noticed a 733 on e-bay claiming to have slipper bearings)

Please let me have your thoughts and experience.

Best regards
