Wartsila’s User Group Forums 50 SG Engine Broken crankcase cover bolt Reply To: Broken crankcase cover bolt


Follow-up to my first post:  We’ve sourced US-made M24 x 90 bolts from our local Fastenal and turned them on the lathe to match the reduced-shank profile of the Wartsila bolts.

After having 2 of the OEM bolts snap off in service and forced units offline, we decided the OEM bolts were unreliable and sought alternatives.   And yes, these were all hand-torqued to spec.
