Diameter of main bores?
Does anyone have the factory range for the diameter of the crankshaft main bores, NO bearings. It should be the spec that machine shops reference when align honing but I cant find it anywhere. Also what size mandrel for align honing? If you have the info please let me know where you found it.
thanks |
Ok I found the info in case someone else needs it later. Main bore size: 53.998mm-54.018mm. 2.1259”-2.1267”. This is from ACL. CLEVITE also has it listed as 54mm-54.01mm and 2.12160”-2.1267”

Lol. I just got my block back from getting decked and was able to measure the main bore that the other Shop aligned honed on Tuesday. 54.00mm exactly. So I guess the spec we referenced in this thread is indeed accurate for those in the future who want align bore and hone information. Thanks for the help y’all.
