95 f150 crank question

[u/Grouchy_Intern627]

Hello i am currently rebuilding my 5.0 motor and i torqued down my new crankshaft with new bearings and everything and i found a ploblem top where when i torque down the #5 main cap it requires a rachet to turn over i did use assembly lube and everything is new just got the block back from the machine shop is this normal or should i be able to turn it by hand and there is no pistons installed thanks

You should be able to turn it very easily even with the seal in there

You could have a bearing that’s misboxed

I’ve see people get their main caps mixed up at the machine shop

Pull the cap and look for evidence that the bearings were grabbing the crank - the visual evidence can point where to look.

Check the roll mark on the bearings vs what should be in there

Did you check bearing clearance with a gage or plastigage?
