I just finished changing my rod bearing since they didn't look too great (had a weak oil pump for years). Had a question though, it seems that rod bolt assembly (stock set up) could easily get loose (no loctite, no lock washer,....) I torqued them to 22ft/pds. I am sure they will not loosen up ?

What engine? My [u]memory[/u] is telling me 40 ft lb for rod bolts and I definately use loctite.

Pierre, This sounds like the correct torque for 5/16 rod bolts, The 40 is for 3/8. Believe me if your wrong the 40 will snap the 5/16 bolt. Loctite is a good thing to use but is not called out in the manual, believe it or not they stay torqued. ------------------ 69 393W Sportsroof Deluxe

Clark, you are right. I was assuming 351W. I should have been more clear in my post.

Thanks guys !! Yes it is definitely 5/16 (302). I probably should have used loctite but like you say no manual (ford or Tom Monroe's)mentions it so I did not. Must be safe.

Rod bolts should be installed and torqued with motor oil or moly lube (if they were re-sized with moly). Loctite should never be used on rod, main or head bolts. Butch
