Im trying to put new connecting rod berrings in my 1984 f 150 300 stright six i have my oil pan off but im not sure how to do this type of job do you have any suggestions
fist of all r u putting in mains too
u should replace them all at once.
to start u need a good torque wrench and some plastigauge and a book with all ur specs. u can get it at most parts stores.
ok take the cap off of one and using a small block or wood or a mallat. not a hammer. knock the cap off and the connecting rod up about a half inch. clean good and put the new bearing in. no oil should get on the back of the bearing. a little assembly grease on the inside of the bearing.
ok take ur plastigauge and put a new bearing in dry on both top and bottom. use a small piece of the plastigauge and put it on the bearing and torque it down, then take it apart and messure how much it smashed it out. that tells u the clearance. if its in spec then u carfully take the smashed plastic out and grease it good and put in back in and torque it down.
do the same for all the rest. if you have a plastigauge showing too much clearance u may still be ok if its realy close but if its mor then 3 to 5 past spec u need a new crank, or have it turned down. remember most specs list new and max. dont go over the max because with new bearing just think how much u had with the old ones
